Cognitive impairment assessment in schizophrenia. purposely a case

Introduction Significant and measurable cognitive symptoms are present at the onset of the disorder and these remain stable in the subsequent period between 2 and 5 years. Their deterioration increases with the course of the disease. Attention, concentration, psychomotor speed and resolution of conceptual tasks are usually affected and are more significant in the presence of positive symptoms.Objectives Sometimes, the typical positive or negative symptoms of the disease do not adequately reflect the severity of cognitive impairment. Measuring this deterioration can be very relevant when evaluating the severity and the prognosis of the disorder.Methods31-year-old male with a previous diagnosis of schizophrenia of 4 years of evolution.

Further, these mice exhibited significant social and cognitive memory impairments, along with hyperactivation of hippocampal dentate gyrus neurons and reduced inhibitory synaptic transmission in this region. However, oral administration of IPA effectively mitigated the histological and electrophysiological alterations, thereby ameliorating the social and cognitive deficits of the mice.

Association between general self-efficacy and health literacy among stroke survivors 1-year post-discharge: a cross-sectional study

Stroke may affect physical functioning, cognition, and mental and social aspects of one’s life. Health literacy and self-efficacy are associated with positive health outcomes and are important factors for managing the diverse consequences of a stroke. However, there is very little literature on the association between health literacy and self-efficacy. This study aimed to investigate the association between health literacy and self-efficacy among stroke survivors 1 year after discharge from hospital. Participants in this cross-sectional study were patients diagnosed with a stroke, mainly a mild stroke, who were referred to rehabilitation in primary care after discharge from hospital in Sweden. Data was collected using questionnaires, performance-based tests, and medical records. Ordinal logistic regression was used to analyze the association between general self-efficacy and health literacy in adjusted models. The analysis revealed that higher levels of general self-efficacy and higher levels of performing activities of daily living were associated with higher levels of health literacy. Stroke survivors with higher general self-efficacy also report higher health literacy 1-year post-discharge from hospital. Future studies should focus on the pathways by which health literacy and general self-efficacy work among stroke survivors and in populations with low health literacy, severe stroke or significant cognitive impairments.

Unilateral Magnetic Resonance Imaging-Guided Laser Interstitial Thermal Therapy Thalamotomy for Essential Tremor.

Essential tremor (ET) affects numerous adults, impacting quality of life (QOL) and often defying pharmacological treatment. Surgical interventions like deep brain stimulation (DBS) and lesional approaches, including radiofrequency, gamma-knife radiosurgery, and magnetic resonance imaging (MRI)-guided focused ultrasound, offer solutions but are not devoid of limitations. This retrospective, single-center, single-blinded pilot study aimed to assess the safety and efficacy of unilateral MRI-guided laser interstitial thermal therapy (MRIg-LITT) thalamotomy for medically intractable ET. Nine patients with ET, unresponsive to medications and unsuitable for DBS, underwent unilateral MRIg-LITT thalamotomy. We assessed tremor severity, QOL, cognitive function, and adverse events (AE) over a 12-month period. Tremor severity significantly improved, with a reduction of 83.37% at 12 months post-procedure. QOL scores improved by 74.60% at 12 months. Reported AEs predominantly included transient dysarthria, proprioceptive disturbances, and gait balance issues, which largely resolved within a month. At 3 months, 2 patients (22%) exhibited contralateral hemiparesis requiring physiotherapy, with 1 patient (11%) exhibiting persistent hemiparesis at 12 months. No significant cognitive impairment was detected post-procedure. Unilateral MRIg-LITT thalamotomy yielded substantial and enduring tremor alleviation and enhanced QOL in patients with ET that is resistant to medication. The AE profile was acceptable. Our findings support the need for additional research with expanded patient cohorts and extended follow-up to corroborate these outcomes and to refine the role of MRIg-LITT as a targeted and minimally invasive approach for ET management. © 2024 The Authors.

Psoriasis and atopic dermatitis in terms of psychosomatic effects

The aim of this paper is to present the review of research into the psychological functioning of children and adults suffering from chronic diseases, with particular emphasis on psoriasis and atopic dermatitis. We have reviewed the scientific articles available in research databases on the topic: psoriasis and atopic dermatitis in terms of psychosomatic effects. It was found that psoriasis and atopic dermatitis interfere with patients’ most vital processes and negatively affect their immediate vicinity. They cause changes in the somatic, mental and social functioning of the patient. Frequently, they also cause a change in behaviour and negatively affect the quality of patients’ lives. Patients with severe psoriasis have an increased risk of death due to circulatory system diseases, cancer, chronic diseases of the lower respiratory tract, diabetes, dementia, infections and kidney diseases. Atopic dermatitis is correlated and may predispose to an increased risk of other atopic disorders, including asthma, hay fever, food allergies, and eosinophilic oesophagitis. It seems that patients with atopic dermatitis are more susceptible to infections and cardiovascular diseases and numerous neuropsychiatric disorders, including depression, attention deficit hyperactivity disorder, speech disorders in childhood, headaches and seizures. There is also a multifactor correlation between AD and osteoporosis, injuries, and fractures. Psoriasis is not only associated with anxiety disorders, depressive disorders and suicidal ideation, but also with significant cognitive functions impairment. In the case of atopic dermatitis, many authors emphasize the association between the occurrence of this skin disease and cognitive impairment, including reduced attention, visual and verbal memory, executive functions and abstract thinking.

The role of clinical characteristics of Lyme borreliosis in predicting cognitive impairment

Background. Lyme disease is characterized by a wide polymorphism of clinical manifestations, including various lesions of the central and peripheral nervous systems. Along with neurological disorders, diverse manifestations and signs of cognitive impairments are often found. Despite the high prevalence of cognitive disorders in Lyme borreliosis, data on their frequency and risk factors are contradictory. The examination of cognitive status is still not included in the standard clinical examination of this category of patients. The aim of the study is to identify predictors that may independently influence the development of cognitive dysfunction in patients with Lyme borreliosis. Materials and methods. A prospective cohort study of 69 patients (47 females, 22 males) diagnosed with Lyme borreliosis, aged between 23 and 77 (average of 49.90 ± 16.26) years, was carried out. The Montreal Cognitive Assessment was used to evaluate cognitive function. To determine the relationship between cognitive dysfunction and its potential predictors, the participants were divided into two groups: patients without cognitive impairment (n = 30) and those with cognitive dysfunction (n = 39) based on the Montreal Cognitive Assessment score. Results. It was found that risk factors for the development of cognitive impairment include: diagnosis of Lyme borreliosis at the age of 45.5 years and older (hazard ratio (HR) 5.09; 95% confidence interval (CI) [1.82–14.27]; p = 0.001), presence of neuroborreliosis (HR 5.98; 95% CI [2.0–17.8]; р < 0.001), Lyme carditis (HR 8.7; 95% CI [1.04–73.06]; р = 0.021), hypertension (HR 7.19; 95% CI [2.32–22.28]; р < 0.001), anxiety disorders. Conclusions. The prospect for further research is to study and analyze the features of the correlation between cognitive and psycho-emotional disorders and the quality of life of patients with different forms and duration of Lyme borreliosis.

APOEε4 Carriers Exhibit Objective Cognitive Deficits: A Cross-Sectional Study in a Single Center Trial.

To explore the association between the apolipoprotein E (APOE) genotype and objectively assessed cognitive function. In this cross-sectional study, 537 participants underwent a neuropsychological assessment for cognitive function and blood testing for APOE genotype. Based on cognitive test results, participants were stratified into two cohorts: Cognitively Unimpaired participants (CU) and Cognitively Impaired participants (CI). The CI group was further divided into Mild Cognitive Impairment (MCI) and Alzheimer's Disease (AD). Furthermore, we conducted age stratification, categorizing participants into three age groups: age 1: <65 years, age 2: 65-75 years, and age 3: >75 years. We assessed the disparities in cognitive function associated with ε4 carrier status across different age brackets. Plasma amyloid-β levels were measured in a cohort of 294 participants to investigate potential interactions involving ε4 carrier status, diagnosis, sex, or plasma markers. The APOE genotypic distribution among the 537 participants was characterized as follows: ε2/ε2 (5 participants), ε2/ε3 (67), ε2/ε4 (13), ε3/ε3 (330), ε3/ε4 (113), and ε4/ε4 (9). Allele frequencies were: ε3 at 78.21%, ε4 at 13.41%, and ε2 at 8.38%. Notably, the ε4 carrier frequency was markedly elevated in the AD group at 81.8% when compared to MCI at 32.8% and CU at 21.3% (p < 0.05). Within the Cognitively Unimpaired (CU) cohort, the sole discernible contrast between ε4+ and ε4- emerged in STT-B (p < 0.05). Within the CI group, ε4 carriers showed statistically poorer scores as compared to non-ε4 carriers in several cognitive tests (p < 0.05). Age stratification result revealed that, among ε4 carriers, cognitive function scores within the age 3 group were significantly inferior to those of age 1 and age 2 groups (p < 0.05). Plasma amyloid-β detection was applied to the 294 participants. We tested plasma amyloid-β (Aβ42) and plasma amyloid-β (Aβ40) levels and calculated the Aβ42/Aβ40 ratio. We found that among female ε4 carriers, both Aβ42 and the Aβ42/Aβ40 ratio were notably lower than their male counterparts (p < 0.05). The ε3/ε3 was the most prevalent among participants, succeeded by ε3/ε4 and ε2/ε3. The least prevalent were ε2/ε4, ε4/ε4, and ε2/ε2 genotypes. The ε3 was predominant, followed by the ε4 and ε2. Individuals with the ε4 allele exhibited significant cognitive impairment, with an especially high prevalence in AD group at 81.8%. The study unveils a pronounced correlation between the ε4 allele and cognitive deficits, implying its potential role in the advancement and severity of cognitive disorders, notably Alzheimer's disease. Cognitive function declines with age in individuals carrying the ε4, and women are more affected by ε4.

The Promise, Mystery, and Perils of Stenting for Symptomatic Internal Jugular Vein Stenosis: A Case Series.

Cerebral venous outflow disorders (CVDs) secondary to internal jugular vein (IJV) stenosis are becoming an increasingly recognized cause of significant cognitive and functional impairment in patients. There are little published data on IJV stenting for this condition. This study aims to report on procedural success. A single-center retrospective analysis was performed on patients with CVD that underwent IJV stenting procedures. From 2019 to 2023, 29 patients with CVD underwent a total of 33 IJV stenting procedures. Most patients (20; 69%) had an underlying connective tissue disorder diagnosis. The mean age of the included patients was 36.3 years (SD 12.4), 24 were female (82.8%), and all were Caucasian except for 2 patients (27; 93.0%). Twenty-eight procedures (85%) involved isolated IJV stenting under conscious sedation, whereas 5 procedures (15%) involved IJV stenting and concomitant transverse sinus stenting under general anesthesia. Thirteen (39%) patients underwent IJV stenting after open IJV decompression and styloidectomy. Three patients had stents placed for stenosis below the C1 tubercle, one of which was for carotid compression. Periprocedural complications occurred in 11 (33%), including intracardiac stent migration in 1 patient, temporary shoulder pain/weakness in 5 (15%), and persistent and severe shoulder pain/weakness in 2 patients (6%). Approximately 75% of patients demonstrated improvement after stenting although only 12 patients (36%) had durable improvement over a mean follow-up of 4.5 months (range 6 weeks-3.5 years). Our experience, along with early published studies, suggests that there is significant promise to IJV revascularization techniques in these patients; however, stenting carries a high complication rate, and symptom recurrence is common. Most neurointerventionalists should not be performing IJV stenting unless they have experience with these patients and understand technical nuances (stent sizing, anatomy, patient selection), which can maximize benefit and minimize risk.

Spiritual Dimension in the Life of a Senior with Dementia

Dementia is a progressive psychiatric disorder characterized by significant cognitive and non-cognitive impairments. This article explores the spiritual needs of seniors with dementia, emphasizing the anthropological constants of spirituality and religiosity. Despite the challenges posed by dementia, maintaining spiritual identity, integrating religious or spiritual rituals, fostering community support, and open communication with caregivers are identified as crucial aspects of spiritual care. The article highlights the diverse spiritual needs of seniors with dementia and stresses the importance of individualized, sensitive approaches to support their overall well-being. The article concludes by emphasizing the importance of spiritual care as an integral component of the bio-psycho-social model of palliative care for seniors with dementia.

Patient and Public Involvement in Technology-Related Dementia Research: Scoping Review.

Technology-related research on people with dementia and their carers often aims to enable people to remain living at home for longer and prevent unnecessary hospital admissions. To develop person-centered, effective, and ethical research, patient and public involvement (PPI) is necessary, although it may be perceived as more difficult with this cohort. With recent and rapid expansions in health and care-related technology, this review explored how and with what impact collaborations between researchers and stakeholders such as people with dementia and their carers have taken place. This review aims to describe approaches to PPI used to date in technology-related dementia research, along with the barriers and facilitators and impact of PPI in this area. A scoping review of literature related to dementia, technology, and PPI was conducted using MEDLINE, PsycINFO, Embase, and CINAHL. Papers were screened for inclusion by 2 authors. Data were then extracted using a predesigned data extraction table by the same 2 authors. A third author supported the resolution of any conflicts at each stage. Barriers to and facilitators of undertaking PPI were then examined and themed. The search yielded 1694 papers, with 31 (1.83%) being analyzed after screening. Most (21/31, 68%) did not make clear distinctions between activities undertaken as PPI and those undertaken by research participants, and as such, their involvement did not fit easily into the National Institute for Health and Care Research definition of PPI. Most of this mixed involvement focused on reviewing or evaluating technology prototypes. A range of approaches were described, most typically using focus groups or co-design workshops. In total, 29% (9/31) described involvement at multiple stages throughout the research cycle, sometimes with evidence of sharing decision-making power. Some (23/31, 74%) commented on barriers to or facilitators of effective PPI. The challenges identified often regarded issues of working with people with significant cognitive impairments and pressures on time and resources. Where reported, the impact of PPI was largely reported as positive, including the experiences for patient and public partners, the impact on research quality, and the learning experience it provided for researchers. Only 4 (13%) papers used formal methods for evaluating impact. Researchers often involve people with dementia and other stakeholders in technology research. At present, involvement is often limited in scope despite aspirations for high levels of involvement and partnership working. Involving people with dementia, their carers, and other stakeholders can have a positive impact on research, patient and public partners, and researchers. Wider reporting of methods and facilitative strategies along with more formalized methods for recording and reporting on meaningful impact would be helpful so that all those involved-researchers, patients, and other stakeholders-can learn how we can best conduct research together.

Patient and Medical Unit Staff Experiences of Proactive and Integrated Consultation-Liaison Psychiatry in The HOME Study: A Qualitative Investigation

Consultation-liaison (C-L) psychiatry services aim to help general hospital staff provide better care for their patients. Recently, many inpatient C-L psychiatry services have adopted proactive and integrated approaches to achieve this aim. Despite these developments, there have been no interview-based studies of patients' and staff members' experiences of the new approaches. To gain an in-depth understanding of patients' and medical unit staff members' experiences of a proactive and integrated C-L psychiatry service for older medical inpatients (Proactive Integrated C-L Psychiatry [PICLP]). We conducted an interview-based qualitative study with thematic analysis. The participants were patients and staff who had experienced PICLP during The HOME Study, a randomized trial that evaluated PICLP in 24 medical units of three UK general hospitals. We conducted 97 interviews: 43 with patients or their proxies (family members who were interviewed on behalf of patients with significant cognitive impairment) and 54 with staff members of all relevant disciplines. Patients and staff both described how PICLP was a helpful addition to medical care and discharge planning. It enhanced the medical unit team's ability to address psychological, psychiatric, and social needs and provide patient-centered care. They welcomed proactive biopsychosocial assessments and the broader perspective that these offered on patients' complex problems. They also valued the integration of C-L psychiatrists into the unit teams and their daily contact with them. For patients, it fostered a therapeutic relationship and helped them to be more engaged in decisions about their medical care and discharge planning. For staff, it enabled ready access to psychiatric expertise and training opportunities. The few reported experiences of PICLP being unhelpful were mainly about the greater number of clinicians involved in patients' care and a lack of clarity about professional roles in the integrated team. We found that older inpatients and medical unit staff experienced PICLP as both acceptable and generally helpful. Our findings add to the existing evidence for the benefits of proactive and integrated C-L psychiatry services.

Neurocognitive Changes in Patients with Post-COVID Depression.

Background: Depression and cognitive impairment are recognized complications of COVID-19. This study aimed to assess cognitive performance in clinically diagnosed post-COVID depression (PCD, n = 25) patients using neuropsychological testing. Methods: The study involved 71 post-COVID patients with matched control groups: recovered COVID-19 individuals without complications (n = 18) and individuals without prior COVID-19 history (n = 19). A post-COVID depression group (PCD, n = 25) was identified based on psychiatric diagnosis, and a comparison group (noPCD, n = 46) included participants with neurological COVID-19 complications, excluding clinical depression. Results: The PCD patients showed gender-dependent significant cognitive impairment in the MoCA, Word Memory Test (WMT), Stroop task (SCWT), and Trail Making Test (TMT) compared to the controls and noPCD patients. Men with PCD showed worse performances on the SCWT, in MoCA attention score, and on the WMT (immediate and delayed word recall), while women with PCD showed a decline in MoCA total score, an increased processing time with less errors on the TMT, and worse immediate recall. No differences between groups in Sniffin's stick test were found. Conclusions: COVID-related direct (post-COVID symptoms) and depression-mediated (depression itself, male sex, and severity of COVID-19) predictors of decline in memory and information processing speed were identified. Our findings may help to personalize the treatment of depression, taking a patient's gender and severity of previous COVID-19 disease into account.

Increasing Teacher Retention and Supporting Students With Low-Incidence Disabilities Through University Partnership

The shortage of teachers is amplified in rural areas where educators work with students with low-incidence disabilities (LID; visual or hearing impairment; significant cognitive impairment; any impairment for which a small number of personnel with highly specialized skills and knowledge are needed for children to receive early intervention services). This scarcity is closely linked to the lack of accessible knowledge for these teachers. Both a high attrition rate and lack of expertise negatively affect the educational outcomes of students with LID. We propose school–university partnerships (SUPs) to alleviate these challenges. This position paper presents the critical elements of a comprehensive SUP by synthesizing programs reported in the literature, including the following elements (a) instructional, assessment, and online resources; (b) mentorship; and (c) professional development. We specifically identify how these elements can improve outcomes of students with LID and alleviate the rural special education teacher shortage. Finally, we discuss the implications of this proposed SUP and implications for practices, policy, and research.

Cognitive Impairment following Mild Traumatic Brain Injury (mTBI): A Review.

Background: Mild Traumatic Brain Injury (mTBI) has been increasingly recognized as a public health concern due to its prevalence and potential to induce long-term cognitive impairment. We aimed to consolidate this observation by focusing on findings of neuropsychological assessments, neuroimaging, risk factors, and potential strategies for intervention to prevent and treat mTBI-associated cognitive impairments. Methods: A thorough search of PubMed, PsycINFO, and Embase databases was performed for studies published until 2024. Studies focusing on cognitive impairment after mTBI, with neurocognitive assessment as a primary outcome, were included. Results: We found consistent evidence of cognitive deficits, such as memory and attention impairments, and affected executive functions following mTBI. Neuroimaging studies corroborate these findings, highlighting structural and functional changes in the brain. Several risk factors for developing cognitive impairment post-mTBI were identified, including age, gender, genetics, and pre-existing mental health conditions. The efficacy of interventions, including cognitive rehabilitation and pharmaceutical treatment, varied across studies. Conclusions: Mild TBI can lead to significant long-term cognitive impairments, impacting an individual's quality of life. Further research is necessary to validate and standardize cognitive assessment tools post-mTBI, to elucidate the underlying neural mechanisms, and to optimize therapeutic interventions.

Study of Pragmatic Skills of Persian-speaking Adults with Autism Spectrum Disorder Based on the Persian Version of Montreal Protocol for the Evaluation of Communication (P.M.E.C.).

Various studies have shown that individuals with autism spectrum disorder (ASD) experience significant cognitive impairments during childhood. Individuals often experience various language disorders that can manifest in different ways. There are also studies indicating that these impairments persist into adulthood for individuals with ASD. This study aimed to evaluate and identify cognitive impairments among Persian-speaking adults with ASD. This research is of a quantitative nature and has been conducted using an experimental method in which two subtests from the Persian Version of the Montreal Protocol for the Evaluation of Communication (P.M.E.C.), including the Metaphor Interpretation and Speech Act Interpretation subtests, were utilized. Thirteen Persian-speaking men with ASD participated in this research, with ages ranging from 25 to 44 years (mean age 32.84, standard deviation 4.17), whose educational levels varied from primary school to 20 years of formal education. The control group consisted of 26 healthy Persian-speaking men who were matched in terms of age and educational level with the ASD group. The Kolmogorov-Smirnov test and a paired t-test were used to compare the two groups. The results indicated that the ASD group performed significantly poorer in both the Metaphor Interpretation subtest (P < 0.001) and the Speech Act Interpretation subtest (P = 0.033) compared to the healthy control group, suggesting cognitive impairments in their abilities. The findings of this research can be valuable for assessment and intervention purposes in rehabilitation centers, as well as in academic and research settings.

Abstract TP75: Age at Time of Stroke Does Not Predict Post-Stroke Fatigue

Introduction: Post-stroke fatigue (PSF) is a long-term sequelae of stroke that negatively impacts patients and their rehabilitation. Approximately 38% of people hospitalized for a stroke are less than 65 years old. Studies regarding PSF and age are sparse and vary in their results. We examined whether age at time of ischemic stroke correlates with the severity of PSF of ischemic stroke patients in a predominantly Afro-Caribbean population. Methods: An IRB-approved prospective, observational study. Patients above 18 years of age with a diagnosis of ischemic stroke in the past 3 years were enrolled after informed consent. Patients with treated depression, significant cognitive impairment, or active cancer were excluded. The Fatigue Assessment Scale (FAS) was used to measure the level of PSF. Linear regression analysis was used to examine the relationship between age at time of stroke and severity of FAS score, adjusted for sex, NIH Stroke Scale (NIHSS), Modified Rankin Scale (mRS), and Beck Depression Inventory (BDI) scores. A general linear model was used to predict log-log-transformed total FAS score from age at stroke, BDI score, mRS score, NIHSS score, and sex. First-order interactions among predictors were investigated; model residuals were examined for skew and for outliers. Results: Of the 121 patients included, 55.4% are female, the mean age is 65.3 +/- 12.1 years old, 93.4% have hypertension, and 60.3% have diabetes mellitus. The median FAS score is 19 (IQR 15-25), median NIHSS score is 3 (IQR 2-5), and median mRS score is 1 (IQR 0-2). Crude Spearman Correlation between age at stroke and total FAS score was -0.07. Age at stroke was not an independent predictor of FAS score (p=0.545). R 2 for the model was 0.38. Both BDI score (p&lt;0.001) &amp; mRS score (p=0.024) were positively associated with transformed FAS score. Conclusion: Our data suggests that age at time of stroke is not independently correlated with severity of PSF in a predominantly Afro-Caribbean population.

Modification of the Paediatric Gastro-oesophageal Reflux Disease Symptom and Quality of Life Questionnaire (PGSQ) for children with cerebral palsy: a preliminary study

ObjectiveGastro-oesophageal reflux disease (GORD) is a common condition affecting children, characterised by the passage of gastric contents into the oesophagus causing pain, vomiting and regurgitation. Children with neurodisability (such as...

Evaluation of nocturnal apnea and airflow limitation as indicators for cognitive dysfunction in patients with chronic obstructive pulmonary disease/obstructive sleep apnea hypopnea syndrome overlap syndrome.

The aim of this study is to investigate how much intermittent hypoxemia and airflow limitation contribute to cognitive impairment in overlap syndrome (OS), which is the coexistence of two common diseases, obstructive sleep apnea hypopnea syndrome (OSAHS) and chronic obstructive pulmonary disease (COPD). We conducted a cross-sectional study of patients with OSAHS, COPD or OS, compared with normal controls, to determine the association between sleep apnea/pulmonary function-related indicators and cognitive dysfunction in individuals with OSAHS, COPD or OS. A total of 157 participants were recruited. Both OSAHS and OS presented lower adjusted Montreal cognitive assessment (MoCA) scores compared with COPD group. In addition, the MoCA score was significantly lower in COPD group compared with control group. The incidence of cognitive impairment was 57.4% in OSAHS group, and 78% in OS group, which were significantly higher than COPD group (29%) and control group (8.8%). Furthermore, a broader range of cognitive domains were affected in OS group compared with OSAHS group. Elevated levels of oxygen desaturation index (ODI) and/or apnea hypopnea index (AHI) were positively correlated with increased Epworth sleeping scale (ESS) in OSAHS and OS. Forced vital capacity (FVC), forced expiratory volume in 1s (FEV1) and peak expiratory flow (PEF) were positively correlated with cognitive scores in OSAHS but not in OS. Serum level of hypoxia-inducible factor-1α (HIF-1α) was significantly higher in OS. Logistic regression identified ODI as an independent risk factor for cognitive impairment in OS, while severity of snoring and PEF were independent risk factors in OSAHS. This study revealed significant cognitive impairment in OS, OSAHS and COPD. Sleep-related indicators are warranted in OS patients for detection, differentiation and grading of cognitive impairment, whereas pulmonary functions are warranted in OSAHS patients for detection and early intervention of cognitive impairment.

The Care Needs of Patients With Cognitive Impairment in Late-Stage Parkinson's Disease.

Cognitive impairment is common in Parkinson's disease (PD), but care needs and resource use for those with significant cognitive impairment are not well established. 675 participants with PD from the international Care of Late-Stage Parkinsonism (CLaSP) study were grouped into those without (n = 333, 49%) and with cognitive impairment (MMSE < 24/30 or diagnosis of dementia or Mild Cognitive Impairment; n = 342, 51%) and their clinical features, care needs and healthcare utilisation compared. The relationship between cognition and healthcare consultations was investigated through logistic regression. Cognitive impairment was associated with more motor and non-motor symptoms, less antiparkinsonian but higher rates of dementia and antipsychotic medication, worse subjective health status and greater caregiver burden. A considerable proportion did not have a pre-established cognitive diagnosis. Care needs were high across the whole sample but higher in the cognitive impairment group. Home care and care home use was higher in the cognitive impairment group. However, use of healthcare consultations was similar between the groups and significantly fewer participants with cognitive impairment had had recent PD Nurse consultations. Worse cognitive impairment was associated with lower frequency of recent PD nurse and multidisciplinary therapy consultation (physiotherapy, massage, occupational therapy, speech training and general nursing). Those with cognitive impairment have more severe PD, higher care needs and greater social care utilisation than those with normal cognition, yet use of health care services is similar or less. Cognitive impairment appears to be a barrier to PD nurse and multidisciplinary therapy consultations. This challenges current models of care: alternative models of care may be required to serve this population. Parkinson's disease is a long-term progressive health condition. Over time, many people with Parkinson's develop problems with thinking and memory, called cognitive impairment. This can negatively impact the daily lives of the person with Parkinson's and their caregiver. It is also thought to be a barrier to accessing healthcare. How people with Parkinson's who have cognitive impairment use healthcare and detail of their care needs is not well known.We analysed data from a large sample of people with advanced Parkinson's from six European countries to investigate their symptoms, care needs and healthcare use. We compared those with cognitive impairment to (342 people) to those without cognitive impairment (333 people).We found that those with cognitive impairment had more severe Parkinson's across a range of symptoms compared to those without cognitive impairment. They also had more care needs, reported their health status to be worse, and their caregivers experienced greater strain from caring. Whilst use of other healthcare services was similar between the two groups, those with cognitive impairment were less likely to have recently seen a Parkinson's nurse than those without cognitive impairment. Further analysis showed an association between cognitive impairment and not having seen a Parkinson's nurse or therapist recently, taking psychiatric symptoms, functional disability and care home residence into account. Therapists included were physiotherapy, massage, occupational therapy, speech training and general nursing. These findings highlight unmet need. We suggest that healthcare should be more targeted to help this group of people, given their higher care needs.

A comparative study of cognitive function in young patients with bipolar disorder with and without non-suicidal self-injury

ObjectiveBipolar disorder (BD) is a chronic mental disorder characterized by alternating or mixed episodes of mania or hypomania and depression. Cognitive function impairment is a frequent associated feature of the disease. While many BD patients also engage in non-suicidal self-injury (NSSI), there is a lack of studies on the cognitive function of BD patients with NSSI. This study aimed to evaluate cognitive functioning of BD patients with NSSI and provide a clinical basis for the differential diagnosis and treatment of BD and NSSI. MethodsA total of 60 BD patients with NSSI, 60 BD patients without NSSI, and 60 healthy controls (HC) were selected for the study. All participants met the inclusion criteria and were not taking any medications, excluding the potential effects of medication on cognitive functions. The following neurocognitive tests were used to measure the cognitive functions in areas such as speed of processing, reasoning and problem solving, attention/vigilance, working memory, visual learning, and verbal learning: The Trail Making Test (TMT), Category Fluency, Digit Symbol Coding Test (DSCT), Brief Visuospatial Memory Test-Revised (BVMT-R), The Neuropsychological Assessment Battery Mazes (NABM), Wechsler Memory Scale Third Edition Spatial Span Test (WMS III-SST), Hopkins Verbal Learning Test-Revised (HVLTR) and Continuous Performance Test and Identical Prs (CPT-IP). ResultsThe findings indicated that BD patients with NSSI exhibited cognitive impairment in all measured cognitive domains. On the other hand, BD patients without NSSI showed less pronounced impairment in terms of speed of processing, but exhibited significant cognitive impairment in the remaining five areas compared to the HC group. ConclusionThe study underscores the presence of cognitive impairment in BD, and the cognitive impairment is more severe in BD patients with NSSI compared to those without NSSI. In conclusion, both individuals with NSSI and those without NSSI in BD exhibit cognitive impairment, which provides ideas and strategies for using cognitive-behavioral therapy to treat BD and NSSI.
