Silent Struggles Within: Alexithymia Unveiled in Irritable Bowel Syndrome: A Systematic Review and Meta-analysis.

In recent years, the presence of alexithymia in patients with irritable bowel syndrome (IBS) has gained more attention, and several studies have evaluated this relationship. However, no clear conclusion has been reported yet. Therefore, we conducted a systematic review and meta-analysis to better understand the association between IBS and alexithymia. We performed a systematic search on the medical databases PubMed, EMBASE, and Scopus using predefined keywords to identify observational studies assessing the association between IBS and alexithymia. The included studies diagnosed IBS using the Rome criteria, and alexithymia was evaluated using the 20-item Toronto Alexithymia Scale (TAS-20) score. We used The Newcastle-Ottawa Scale to evaluate the quality of included studies. The primary summary outcome was the mean difference in TAS-20 scores. We included 7 studies involving 1,513 individuals in our qualitative analysis, with 6 of them included in our quantitative analysis. All studies were considered to be of satisfactory quality according to the Newcastle-Ottawa Scale criteria. We found significantly higher TAS-20 scores in IBS patients compared to controls (8.063 [95% CI, 2.554-13.572]). However, no significant mean difference in TAS-20 scores was observed in IBS vs inflammatory bowel disease patients (0.884 [95% CI -2.536-4.304]). We demonstrated that IBS is associated with an increased risk of developing alexithymia. However, our study did not show a significant difference in TAS-20 scores between patients with IBS compared to inflammatory bowel disease.

Association of neuroimaging measures with facial emotional processing in healthy adults: a task fMRI study.

Investigating the neural processing of emotion-related neural circuits underlying emotional facial processing may help in understanding mental disorders. We used two subscales of the Toronto Alexithymia Scale to assess the emotional cognitive of 25 healthy participants. A higher score indicates greater difficulty in emotional perception. In addition, participants completed a n-back task during functional magnetic resonance imaging. Psychophysiological interaction analysis was used to explore the functional connectivity (FC) of neural circuits. Next, we used elastic-net regression analysis for feature selection and conducted correlation analysis between the neuroimaging measures and questionnaire scores. Following a 3-fold cross-validation, 5 neuroimaging measures emerged as significant features. Results of correlation analysis demonstrated that participants with higher TAS scores exhibited increased FC between the amygdala and occipital face area (OFA) during facial stimulus processing, but decreased connectivity during emotional processing. These findings suggested that individuals with poor emotional recognition exhibited increased connectivity among face-related brain regions during facial processing. However, during emotional processing, decreasing neural synchronization among neural circuits involved in emotional processing affects facial expression processing. These findings suggest potential neural marker related to subjective emotional perception, which may contribute to the diagnosis and treatment of emotional dysregulation in individuals with psychiatric conditions.

Investigation of Deficits in Auditory Emotional Content Recognition by Adult Cochlear Implant Users through the Study of Electroencephalographic Gamma and Alpha Asymmetry and Alexithymia Assessment.

Given the importance of emotion recognition for communication purposes, and the impairment for such skill in CI users despite impressive language performances, the aim of the present study was to investigate the neural correlates of emotion recognition skills, apart from language, in adult unilateral CI (UCI) users during a music in noise (happy/sad) recognition task. Furthermore, asymmetry was investigated through electroencephalographic (EEG) rhythm, given the traditional concept of hemispheric lateralization for emotional processing, and the intrinsic asymmetry due to the clinical UCI condition. Twenty adult UCI users and eight normal hearing (NH) controls were recruited. EEG gamma and alpha band power was assessed as there is evidence of a relationship between gamma and emotional response and between alpha asymmetry and tendency to approach or withdraw from stimuli. The TAS-20 questionnaire (alexithymia) was completed by the participants. The results showed no effect of background noise, while supporting that gamma activity related to emotion processing shows alterations in the UCI group compared to the NH group, and that these alterations are also modulated by the etiology of deafness. In particular, relative higher gamma activity in the CI side corresponds to positive processes, correlated with higher emotion recognition abilities, whereas gamma activity in the non-CI side may be related to positive processes inversely correlated with alexithymia and also inversely correlated with age; a correlation between TAS-20 scores and age was found only in the NH group. EEG gamma activity appears to be fundamental to the processing of the emotional aspect of music and also to the psychocognitive emotion-related component in adults with CI.

“Our similarities are different” The relationship between alexithymia and depression

Alexithymia is a multi-faceted personality trait, which is the inability to recognize and describe emotions. It is associated with a multitude of mental health problems, and its implication for the diagnosis and treatment of depression remains unclear. The current study explored the nuances of the relationship between alexithymia and depression in a sample of 210 patients with depression. We assessed alexithymia with the 20-Item Toronto Alexithymia Scale (TAS-20) and depression with the Beck Depression Inventory (BDI-I). The mean TAS-20 score was 57.47 ± 10.63, and the mean BDI-I score was 49.33±9.24. We explored the network structure of alexithymia and depression. Items related to difficulties in identifying, describing, and expressing feelings were prominent in the alexithymia network. Joy, guilt, and self-dislike stand out in the depression network. In our analysis, we were able to show the crescent relationship between depression and alexithymia, with an inflection point at a TAS-20 score of 53. Although the correlation-concordance index was moderate (0.41; 95 %CI: 0.29–0.51), both scales greatly overlap. In the joint network of alexithymia and depression, we could identify bridge (i.e., connecting) items between alexithymia and depression. These were difficulties understanding and relating feelings to physical and body sensations on the alexithymia side, and self-dislike, crying, and somatic concern on the depression side. Taken together, they point to the pivotal role of alexithymia in the somatization/embodiment of emotions and feelings in depression.

Attitudes Toward Dating Violence, Social Impact, and Alexithymia in University Students: A Structural Equation Modeling.

This research was conducted to determine the effects of social impact and alexithymia on attitudes toward dating violence. Additionally, the interaction between them was examined. In this context, the effect of social impact on alexithymia was also examined. In addition, this research tried to determine whether alexithymia has a mediating role between social impact and attitudes toward dating violence. The study was descriptive and cross-sectional. There was a total of 582 participants in the study. The study used the Sociodemographic Questionnaire Form, Social Impact Scale (SIS), 20-Item Toronto Alexithymia Scale (TAS-20), and Dating Violence Scale (DVS) for data collection. The study used the descriptive statistics, spearman correlation analysis and structural equation modeling in the evaluation of the data. Participants' SIS scores had a statistically significant and positive correlation with their TAS-20 scores (p < .01), while they had a statistically significant and negative correlation with their DVS scores (p < .01). In addition, a statistically significant and negative correlation was found between TAS-20 scores and DVS scores (p < .01). SIS scores directly affected the TAS-20 (effect value = 0.481; p = .001) and DVS scores (effect value = -0.405; p = .001). Similarly, the TAS-20 scores had a direct effect on the DVS scores (effect value = -0.261; p = .008). In addition to this direct effect of TAS-20 scores, there was a significant mediator effect between the SIS scores and DVS scores (effect value = -0.126; p = .008). In this study, it was established that social impact effects both alexithymia and attitudes toward dating violence, and moreover, alexithymia influences attitudes toward dating violence. Additionally, it was identified that alexithymia serves as a mediator in the relationship between social impact and attitudes toward dating violence.

Emotional awareness in patients with amyotrophic lateral sclerosis.

It has been recently acknowledged that deficits in experiencing and processing one's own emotions, also termed alexithymia, may possibly feature the frontotemporal-spectrum disorders. This study aims to determine whether alexithymia could be included within the frontotemporal syndromes of amyotrophic lateral sclerosis (ALS). Alexithymic traits were estimated in a cohort of 68 non-demented ALS patients with the 20-item Toronto Alexithymia Scale (TAS-20). Patients were assessed for the identification of motor-phenotypes and frontotemporal syndromes based on current classification criteria. Spearman's coefficients explored the correlates of TAS-20 measures with motor-functional profiles, global cognitive, social-cognitive (emotion recognition and empathy) and behavioral status. Abnormal TAS-20 scores were found in 13% of patients, and their distribution did not vary within motor and frontotemporal phenotypes. Significant associations were detected between TAS-20 and executive (p ≤ .011), memory (p = .006), state-anxiety (p ≤ .013) and depression measures (p ≤ .010). By contrast, TAS-20 scores were unrelated to social-cognitive performances, dysexecutive and apathetic profiles. Disease duration was the only motor-functional feature being related to the TAS-20 (p ≤ .008). Alexithymia of potential clinical relevance occur in a minority of ALS patients, and its neuropsychological correlates mostly resemble those featuring the general population. Hence, it is unlikely that alexithymia is a specific feature of frontotemporal-spectrum characterizing ALS, rather it could be an expression of psychogenic factors as a reaction to the disease.

Alexithymia Increases Pericranial and Cervical Muscle Tenderness in Women with Migraine.

Background/Objectives: Alexithymia is characterized by a deficit in identifying and communicating feelings. Emerging evidence suggests that alexithymia is highly prevalent in migraine, in a complex interplay with psychiatric comorbidity. Pericranial/cervical muscle tenderness is a remarkable clinical feature in a large proportion of migraine patients. This pilot study aimed at investigating the relationship between alexithymia and pericranial/cervical muscle tenderness in female migraineurs. Methods: A total of 42 female patients fulfilling the diagnostic criteria for migraine were enrolled into this pilot, observational, cross-sectional study after informed consent was obtained. Each patient underwent a psychological assessment to identify any alexithymia by means of TAS-20, anxiety/mood comorbidity (by means of STAI-Y1 STAI-Y2, BDI-II), and migraine-related disability (by means of HIT-6), and a physical cranial/cervical musculoskeletal examination. Palpation of pericranial and cervical muscles was carried out in the standardized manner. A Cumulative Muscle Tenderness (CUM) score (0-6) was calculated for each patient. A multivariate analysis was performed to investigate any association amongst the TAS-20 score, the CUM score, and the following covariates: BDI-II, STAI-Y1, STAI-Y2, and HIT-6 scores, age, disease duration, monthly migraine days, and average head pain intensity in the previous three months. Results: Overall, 35.6% of the sample had alexithymia. The multivariate analysis detected a linear and independent relationship between the TAS-20 and CUM scores, with a statistically significant (p = 0.017) association. Conclusions: This pilot study suggests that alexithymia plays a role in increasing pericranial/cervical muscle tenderness in migraine, independently from psychiatric comorbidity. A novel therapeutical approach, targeting alexithymia, may well reduce muscular tenderness in female migraineurs.

Alexithymia in primary ciliary dyskinesia.

Recent evidence suggests that alexithymic deficits in emotional processing may also affect physical health, and alexithymia may also be associated with organic disorders. The emotional well-being of patients with primary ciliary dyskinesia (PCD) is often negatively affected by uncertainty about the prognosis, lack of ongoing medical care, and lack of symptom control. This study aims to evaluate the frequency of alexithymia and its possible impact on the management of childhood PCD. Subjects were recruited from patients with PCD and healthy volunteers aged 8-18 years. The questionnaire included sociodemographic characteristics and self-report scales. Data were compared between patient and control groups. In the >14 years of age group, the total Toronto Alexithymia Scale (TAS-20) score was significantly higher in the patients (56.60 ± 13.01) compared to the control group (46.47 ± 7.50) (p = .007). There were 6 (30) patients with a TAS-20 score ≥61. There was a significant correlation between TAS-20 and Pediatric Quality of Life (PedsQL) score (child), but no correlation between TAS-20 and Kovacs Children Depression Inventory (CDI) and PedsQL score (parents). The TAS-20 score was significantly higher in patients with bronchiectasis (p = .035), nasal polyps (p = .045), and siblings with PCD (p = .001). Furthermore, the TAS-20 score had a significant negative correlation with pulmonary function tests. Although this study is based on limited data from a single center and cannot be generalized to all PCD patient communities, our results show that PCD patients are more likely to have alexithymia compared to healthy controls and highlight the need to evaluate for alexithymia in patients with PCD. It is important for pediatric pulmonologists to have a thorough knowledge of the alexithymic features associated with PCD and to refer patients to pediatric psychiatry when necessary, especially in patients who are noncompliant with treatment protocols.

Comparative Effectiveness of Supervised and Home-Based Rehabilitation after Anterior Cruciate Ligament Reconstruction in Competitive Athletes.

Background: After the increasingly common anterior cruciate ligament reconstruction (ACLR) procedure in competitive athletes, rehabilitation is crucial for facilitating a timely return to sports (RTS) and preventing re-injury. This pilot study investigates the patient-reported outcomes of postoperative rehabilitation in competitive athletes, comparing supervised rehabilitation (SVR) and home-based rehabilitation (HBR). Methods: After ACLR, 60 (out of 74 screened) athletes were recruited and equally divided into HBR and SVR groups using non-probability convenience sampling, with each group comprising 15 males and 15 females. The rehabilitation outcomes in the respective groups were evaluated at 8 months using measures (Tegner Activity Scale [TAS], International Knee Documentation Committee subjective knee form [IKDC-SKF], ACL Return to Sport after Injury [ACL-RSI]) and objective parameters (isometric muscle strength, hamstring/quadricep asymmetry). RTS was evaluated at 9 months, with ACL re-injury rates recorded approximately 6 months post-RTS. Results: Both groups exhibited decreased TAS scores (HBR: 8 to 6, SVR: 8 to 7), with the SVR group demonstrating superior postoperative IKDC-SKF scores (81.82 vs. 68.43) and lower ACL-RSI scores (49.46 vs. 55.25). Isometric and isokinetic muscle strength, along with asymmetry values, was higher in the SVR group 8 months post-ACLR (p < 0.05). The SVR group showed a higher RTS rate to the same level (76.6% vs. 53.3%), while the re-injury rate was the same in both the rehabilitation groups (3.3%). Conclusions: Although both rehabilitation approaches yielded comparable outcomes, SVR may demonstrate some superior biomechanical improvements in athletes, resulting in a higher RTS rate. However, the psychological outcomes and re-injury rates did not significantly differ between the groups, emphasizing the need to address individual psychological needs during rehabilitation. Further investigation is recommended with a larger sample size to address the differences of gender among competitive athletes.

Do MRI Results Represent Functional Outcomes Following Arthroscopic Repair of an Isolated Meniscus Tear in Young Patients?-A Prospective Comparative Cohort Study.

The use of postoperative MRI to assess the healing status of repaired menisci is a long-standing issue. This study evaluates and compares functional and MRI outcomes following an arthroscopic meniscus repair procedure with the aim of postoperative MRI diagnostic accuracy clarification in young patients. A total of 35 patients under 18 years old who underwent isolated meniscus repair were included. The Pedi-IKDC score, Lysholm score, and Tegner activity index (TAS) were compared between the groups formed according to the Stroller and Crues three-grade classification of postoperative MRI-based evaluations. Grade 3 MRI views were classified as unhealed, grade 2 as partially healed, and grade 1 as fully healed within the repaired meniscus, whereas grade 3 cases were considered unsuccessful due to MRI evaluation. MRI assessment revealed 4 cases of grade 1 (11.4%), 14 cases of grade 2 (40.8%), and 17 cases of grade 3 (48.0%) lesions. Pedi-IKDC and TAS scores were significantly higher among MRI grade 2 patients than among MRI grade 3 patients (p < 0.05). Weak negative correlations between MRI grades and all functional scales were found (p < 0.05). ROC analysis showed that Pedi-IKDC and TAS scores could correctly classify 77% and 71% of MRI grade 3 patients, respectively. The optimal cut-off values to detect grade 3 patients were 88.74 for the Pedi-IKDC score and 4.5 for the TAS score. To conclude, established functional score cut-off values may help identify unhealed meniscus repair patients.

Alexithymia and Suicidal Ideation in Iranian Patients With Psoriasis

Background: Evidence highlighted the high prevalence of some mental problems among individuals with psoriasis, including alexithymia and suicidal ideation. Objectives: The present study aims to investigate the prevalence and comorbidity of alexithymia and suicidal ideation in individuals with psoriasis in Iran. Materials &amp; Methods: This cross-sectional study was conducted on 100 patients with psoriasis referred to Razi Dermatology Clinic and Beesat Clinic of hospitals affiliated to Guilan University of Medical Sciences, Rasht, Iran, in 2020. Psoriasis was diagnosed by a dermatologist, and the demographic and clinical characteristics of patients were recorded. The Toronto alexithymia scale (TAS-20) and the Beck scale for suicidal ideation (BSSI) were used to assess alexithymia and suicidal thoughts. Results: The mean age of patients was 37.56±10.58 years, and 51% were female. Among patients, 52% had alexithymia, 23% were at high risk of suicide, and 6% were at very high risk of suicide. The moderate severity of psoriasis had a significant association with suicidal thoughts (P&lt;0.05). The TAS-20 score had a significant association with the male gender and younger age, and the BSSI score had a significant association with the psoriasis area (P=0.003). The highest score of BSSI was seen in those with psoriasis in the face and limb/trunk (10±4.36 and 8.56±8.52, respectively). Conclusion: Patients with psoriasis exhibit a significant prevalence of alexithymia and suicidal thoughts. Additionally, younger age and male gender were identified as factors associated with alexithymia in this population.

Psychopathological characteristics in patients with arginine vasopressin deficiency (central diabetes insipidus) and primary polydipsia compared to healthy controls.

Distinguishing arginine vasopressin deficiency (AVP-D; central diabetes insipidus) from primary polydipsia (PP), commonly referred to as psychogenic polydipsia, is challenging. Psychopathologic findings, commonly used for PP diagnosis in clinical practice, are rarely evaluated in AVP-D patients, and no comparative data between the two conditions currently exist. Data from two studies involving 82 participants [39 AVP-D, 28 PP, and 15 healthy controls (HC)]. Psychological evaluations were conducted using standardized questionnaires measuring anxiety [State-Trait Anxiety Inventory (STAI)], alexithymia [Toronto Alexithymia Scale (TAS-20)], depressive symptoms (Beck's Depression Inventory-II (BDI-II), and overall mental health [Short Form-36 Health Survey (SF-36)]. Higher STAI, TAS-20, and BDI-II scores suggest elevated anxiety, alexithymia, and depression, while higher SF-36 scores signify better overall mental health. Compared to HC, patients with AVP-D and PP showed higher levels of anxiety (HC 28 points [24-31] vs AVP-D 36 points [31-45]; vs PP 38 points [33-46], P < .01), alexithymia (HC 30 points [29-37] vs AVP-D 43 points [35-54]; vs PP 46 points [37-55], P < .01), and depression (HC 1 point [0-2] vs AVP-D 7 points [4-14]; vs PP 7 points [3-13], P < .01). Levels of anxiety, alexithymia, and depression showed no difference between both patient groups (P = .58, P = .90, P = .50, respectively). Compared to HC, patients with AVP-D and PP reported similarly reduced self-reported overall mental health scores (HC 84 [68-88] vs AVP-D 60 [52-80], P = .05; vs PP 60 [47-74], P < .01). This study reveals heightened anxiety, alexithymia, depression, and diminished overall mental health in patients with AVP-D and PP. The results emphasize the need for careful interpretation of psychopathological characteristics to differentiate between AVP-D and PP.

Patella Fractures outcome after Tension Band Wiring; a Cross-sectional Study

Objective: The most common technique for fixing patella fractures is tension band wiring (TBW). The current study aimed to assess the functional and radiological outcomes of the patellar fractures treated by TBW. Patients and Methods: This retrospective cohort study was performed on 78 patients who underwent TBW of patellar fracture in Akhtar Orthopedic Hospital, Tehran, Iran, from September 2015 to April 2018 and had completed a two-year follow-up. A surgical intervention consisting of open reduction and internal fixation was performed on all patients using TBW. Patients were evaluated two years postoperatively by clinical examination, radiographic investigation, and three scales (Tegner activity score [TAS], Lysholm knee score [LKS], and lower extremity functional scale [LEFS]). Result: Of the 78 patients, 48 (61.5%) were male, with a mean age of 36.7 13.1 years. Postoperatively, 41 (52.6%) patients had anterior knee pain, and four (5%) patients had an infection. Knee range of motion was limited in 20 (25.6%) patients. The mean postoperative TAS, LKS, and LEFS mean scores were 4.3 1.34, 85.97 9.21, and 69.62 6.68, respectively. Age was inversely correlated with LKS and LEFS, as both scores decreased with increasing age (p 0.001, r:-0.4). Younger patients (under 30 years old) were more likely to reach their pre-injury TAS score than older patients (p 0.001). In addition, patellofemoral osteoarthritis and patella baja were significantly higher in patients with comminuted fractures than in those with simple fracture patterns (p 0.001). Conclusion: We found acceptable outcomes after fixation with TBW, especially in younger patients; LKS and LEFS scores were lower in the elderly, and younger patients were more likely to reach closer to their pre-injury TAS score. Furthermore, patellofemoral osteoarthritis and patella baja were associated with comminuted patella fractures.

Evaluation of alexithymia, anger and anxiety depression levels in smokers

ABSTRACT Objective Smokingis a major mental health concern due to its addictive nature and its status asthe leading preventable cause of premature death worldwide. This study aimed toexamine the levels of alexithymia, anger, anxiety, and depression in smokerscompared to nonsmokers. Materials and Methods Thiscase-control study involved 176 smokers from a Smoking Cessation Clinic and 175age- and gender-matched nonsmokers. Participants completed assessments usingthe Toronto Alexithymia Scale (TAS-20), State-Trait Anger Expression Inventory(STAXI), and Hospital Anxiety and Depression Scale (HADS). Nicotine dependencein smokers was measured using the Fagerström Nicotine Dependency Test.Statistical analysis was performed using SPSS 22.0. Findings Significantdifferences were observed between smokers and nonsmokers in TAS, TAS-1, TAS-2,HADS-A, and HADS-D scores. Smokers exhibited higher levels of alexithymia, anger expression, and anxiety, while nonsmokers demonstrated better angercontrol. Additionally, addiction levels in smokers were associated withvariations in TAS, TAS-1, TAS-2, TAS-3, STAXI scores (SA, AC, AI, AO), andHADS-A, highlighting a complex interplay between addiction, psychologicalfactors, and smoking habits. Result This study establishes a link between smoking status, addictionlevels, and elevated alexithymia, anger, anxiety, and depression. The findingsunderscore the psychological impact of smoking, contributing valuable insightsfor mental health interventions in individuals with smoking habits.

Alexithymia and depression may predict treatment failure in patients undergoing Gamma Knife radiosurgery for trigeminal neuralgia: the potential contribution of colored pain drawings.

Gamma Knife radiosurgery (GKRS) effectively achieves high rates of pain control in trigeminal neuralgia (TN); however, psychological factors can also impact how individuals perceive pain and respond to treatment. The authors aimed to measure the effects of alexithymia and depression on GKRS outcomes, as well as the potential role of colored pain drawings (CPDs) in identifying patients who require additional psychological support. Seventy-three medically intractable, typical patients with TN were included. Participants completed a visual analog scale (VAS), the Toronto Alexithymia Scale (TAS-20), and the Turkish version of the Beck Depression Inventory-II (BDI-II). Participants used colored pens to draw their pain patterns on standardized face charts and CPDs were categorized as expected or unexpected. Based on the Barrow Neurological Institute pain scale, patients were categorized as responders or nonresponders. Most patients (63%) were female, and the median age was 60 (range 27-88) years. Of 73 patients, 56 (76.7%) were responders and 17 (23.3%) were nonresponders. Forty-nine patients (67.1%) had expected CPDs, whereas 24 (32.9%) had unexpected CPDs. Responder and nonresponder groups had similar ages, genders, education, comorbidities, and initial VAS scores. Both groups preferred the colors red and black to describe intense pain (79.2% vs 67.3%, p = 0.411). Significantly better pain relief was observed in patients with expected CPDs than in those with unexpected CPDs (87.8% vs 54.2%, p = 0.003). The unexpected CPD group had significantly more alexithymia (58.3% vs 32.7%, p = 0.045). The mean BDI-II score of the cohort was 26 (range 15-37) and was significantly higher in the unexpected group (28.3 vs 24.8, p = 0.028). Unexpected CPD (OR 12.540) and higher TAS-20 score (OR 3.22) increased treatment failure risk. The outcomes of TN treatment can be influenced by psychological factors, and patients with TN with higher total TAS-20 and BDI-II scores, along with unexpected CPDs, had an increased likelihood of treatment failure. CPDs can be accessed quickly and may allow the physician to screen out most patients with unfavorable psychometrics and proceed with the necessary treatment with appropriate psychological support.

Cross-cultural differences in self-reported and behavioural emotional self-awareness between Japan and the UK

ObjectiveHow we express and describe emotion is shaped by sociocultural norms. These sociocultural norms may also affect emotional self-awareness, i.e., how we identify and make sense of our own emotions. Previous studies have found lower emotional self-awareness in East Asian compared to Western samples using self-report measures. However, studies using behavioural methods did not provide clear evidence of reduced emotional self-awareness in East Asian groups. This may be due to different measurement tools capturing different facets of emotional self-awareness.ResultsTo investigate this issue further, we compared the emotional self-awareness of Japanese (n = 29) and United Kingdom (UK) (n = 43) adults using the self-report Toronto Alexithymia Scale (TAS-20), alongside two behavioural measures – the Emotional Consistency Task (EC-Task) and the Photo Emotion Differentiation Task (PED-Task). Japanese adults showed higher TAS-20 scores than UK participants, indicating greater self-reported difficulties with emotional self-awareness. Japanese participants also had lower EC-Task scores than UK adults, indicating a lower ability to differentiate between levels of emotional intensity. PED-Task performance did not show clear group differences. These findings suggest that cross-cultural differences in emotional self-awareness vary with the task used, because different tasks assess distinct aspects of this ability. Future research should attempt to capture these different aspects of emotional self-awareness.

The impact of family alexithymia on the severity of restrictive eating disorders in adolescent patients

BackgroundAlexithymia is the inability to identify and describe one’s own emotions. Adolescents who suffer from Restrictive Eating Disorders (REDs) show a higher prevalence of alexithymia than the general population.MethodsThe study explored the correlation between levels of alexithymia in mothers, fathers, and adolescents affected by REDs and patients’ ability to recognize their emotions. The study also aimed to evaluate if patients’ emotional distress can significantly impact the severity of their disorder and functioning measured by the Clinical Global Impression Scale - Severity (CGI-S) and the Children’s Global Assessment Scale (CGAS). We enrolled 67 families of adolescents affected by REDs. Parents and patients’ levels of alexithymia were assessed through the Toronto Alexithymia Scale (TAS-20). Spearman’s correlation shows a statistically significant correlation between mothers and patients’ levels of alexithymia.ResultsOur findings also suggest that fathers and mothers’ TAS scores correlate with each other. However, there is no statistically significant relationship between the influence of the TAS scores of fathers and sons/daughters.ConclusionsIn conclusion, mothers’ level of alexithymia could influence both fathers and patients’ difficulty in identifying and describing their own emotions. This relationship can be investigated further when considering externally oriented thinking. However, the severity of the disease and overall functioning do not appear to be affected by patients’ levels of alexithymia.

Gender difference in association between clinical symptoms and alexithymia in chronic schizophrenia: A large sample study based on Chinese Han population

BackgroundAlexithymia, a prevalent social cognitive impairment in schizophrenia, remains insufficiently studied. Though some studies propose a link between alexithymia and clinical symptoms of schizophrenia, this connection lacks consistent confirmation. Additionally, there is limited research on gender difference in alexithymia among schizophrenia patients. To fill this gap, our study aimed to conduct a large-sample survey of Chinese Han patients with chronic schizophrenia to explore whether there are gender differences between clinical symptoms and alexithymia. MethodsWe obtained sociodemographic characteristics of 987 schizophrenia patients, measured their clinical symptoms using the Positive and Negative Syndrome Scale (PANSS), and assessed their self-reported alexithymia using the Toronto Alexithymia Scale (TAS-20). ResultsIn patients with chronic schizophrenia, the prevalence of alexithymia did not differ between genders (male: 35.51 % vs. female: 26.91 %, P = 0.018). Correlation and linear regression analyses revealed that PANSS scores and TAS-20 scores were widely correlated in both male and female patients. In particular, multiple linear regression analysis showed that the TAS total score was positively correlated with negative symptoms and cognitive symptoms in male patients, while it was positively correlated with negative symptoms and depressive symptoms in female patients. ConclusionOur study suggests that the prevalence of alexithymia in patients with chronic schizophrenia does not differ between genders. Negative symptoms are related to the TAS-20 total score in both male and female patients, while cognitive symptoms are only related to the TAS-20 total score in male patients, and depressive symptoms are only related to the TAS-20 total score in female patients.

THU113 Psychopathological Characteristics In Patients With Arginine Vasopressin Deficiency (Central Diabetes Insipidus) And Primary Polydipsia

Abstract Disclosure: J. Beck: None. C. Atila: None. J. Refardt: None. Z. Erlic: None. J.B. Drummond: None. B.S. Soares: None. F. Beuschlein: None. B.F. Winzeler: None. M. Christ-Crain: None. Introduction The differential diagnosis between arginine vasopressin deficiency (AVP-D), formally known as central diabetes insipidus, and primary polydipsia (PP) is challenging. In clinical routine, psychopathologic findings are often used as a hallmark for diagnosing PP; thus, it is often referred to as psychogenic polydipsia. Yet, psychopathologic characteristics are barely assessed in patients with AVP-D, and to date, no data exist comparing AVP-D and PP with regard to these features. Therefore, in this study, we aimed to compare levels of anxiety, depression, alexithymia, and overall mental health in patients with AVP-D and PP. Methods This study combined data from two diagnostic studies conducted at three tertiary medical centers. In total, 82 participants (n=39 with AVP-D, n=28 with PP, and n=15 healthy controls [HC]) underwent a psychological evaluation with standardized questionnaires at study inclusion. Anxiety levels were assessed using the State-Trait Anxiety Inventory, mood using the Beck’s Depression Inventory, alexithymia using the Toronto Alexithymia Scale, and overall physical and mental health using the Short Form 36 Health Survey (SF-36). Higher STAI, BDI, and TAS scores indicate higher anxiety, depression, and alexithymia levels. Higher SF-36 scores indicate better health and less disability. Results Compared with HC, patients with AVP-D and PP showed increased levels of anxiety (HC 28 points [24, 31] vs. AVP-D 36 points [31, 45], p&amp;lt;0.01; vs. PP 38 points [33, 46], p&amp;lt;0.01), depression (HC one point [0, 2] vs. AVP-D 7 points [4, 14], p&amp;lt;0.01; vs. PP 7 points [3, 13], p&amp;lt;0.01), and alexithymia (HC 30 points [29, 37] vs. AVP-D 43 points [35, 54], p&amp;lt;0.01; vs. PP 46 points [37, 55], p&amp;lt;0.01). Levels of anxiety, depression, and alexithymia showed no difference between patients with AVP-D and PP (p=0.58, p=0.90, p=0.50). Compared with HC, patients with AVP-D and PP reported comparable reduced self-reported mental health scores (HC 84 [68, 88] vs. AVP-D 60 [52, 80], p=0.05; vs PP 60 [47, 74], p&amp;lt;0.01). Conclusion This is the first study demonstrating comparable increased levels of anxiety, depression, alexithymia, and overall reduced mental health in patients with AVP-D and PP. Based on these data, psychopathological findings should not be used as a hallmark to differentiate between both conditions. Presentation: Thursday, June 15, 2023

Alexithymia characteristics are associated with salience network activity in healthy participants: an arterial spin labeling study

BackgroundAlexithymia, a personality trait characterized by difficulties in identifying and expressing their emotions despite having a range of emotional experiences, can impact individuals’ stress coping mechanisms. While many studies have investigated brain functions associated with specific tasks in relation to emotion processing, research focusing on resting-state brain functions has been limited. Thus, the aim of this study was to investigate the relationship between alexithymia and brain function by analyzing arterial spin labeling (ASL) data obtained during the resting state.MethodsA brain structural and functional imaging study was conducted on 42 healthy adult men and women using ASL and the 20-item Toronto Alexithymia Scale (TAS-20) questionnaire survey. Cerebral blood flow and functional connectivity values were calculated for regions of interest in the default mode network, saliency network, and central executive network from the ASL data. Correlation analysis was performed with TAS20 scores, and partial correlation analysis was conducted to control for anxiety and depression.ResultsThe functional connectivity analysis revealed a negative correlation between the functional connectivity of the right insular cortex and left anterior cingulate cortex and the total score of TAS, as well as difficulty identifying feelings and difficulty describing feeling subscores, indicating that the higher the scores, the weaker the functional connectivity between these regions (T = -3.830, p = 0.0013, R = -0.5180). This correlation remained significant even after controlling for anxiety and depression using partial correlation analysis.ConclusionThe present study revealed differences in the activity of the Saliency Network at rest as measured by ASL, which were independent of anxiety and depression, and varied depending on the severity of alexithymia. This functional change may underlie the neural basis of decreased emotional processing observed in alexithymia. These findings may contribute to the elucidation of the neural mechanisms of alexithymia, which can lead to social impairments, and suggest the usefulness of ASL measurement as a biomarker of alexithymia.
