Impaired age self-consciousness in latent schizophrenia

IntroductionThe topic of research was phenomenon of impaired age self-consciousness in non-psychotic latent schizophrenia patients defined.ObjectivesTo explore features of impaired age self-identity and to determine syndromic affiliation of the syndrome in comparison with premorbid personality disorders traits.MethodsThe study sample comprised 141 patients with latent schizophrenia (pseudo neurotic (F21.3 - 64.5%, 91 patients), coenesthopathic (F20.8 - 25.5%, 36 patients) and pseudo psychopathic (F21.4, - 9.9%, 14 patients)) aged 16-31 (average 22.1 years old) in 2007-2019. A follow-up, experimental psychological and clinical study was conducted.ResultsThe onset of impaired age self-identity was dominated by a radical drop of the subjective age in self-conscious mind of the patients accompanied by a tormented feeling of loss of self-dependence, role autonomy, helplessness, inability of decision making and to be answerable. Patients described this sudden condition as a loss of ‘maturity feeling’ and return to the juvenile perception of self. In a delusive and unclear manner, phrases such as ‘I feel inferior to others as if a helpless child among adults’, ‘I feel as if my childhood is back’ were uttered. Excessive worrying and enlivening of childhood memories were also included. This correlates to occurrence of humble and sometimes dependent/avoidant behavior, feeling of helplessness and fear with respect to caring for one self, rising subordination and suggestibility.ConclusionsThis phenomenon of regress to earlier ontogenetic level of personal development reported as impaired age self-consciousness can thus be regarded as an obligate form of depersonalization in patients with latent schizophrenia.

Pervasive refusal syndrome: systematic review of case reports.

Pervasive refusal syndrome (PRS) is a complex condition that affects young people leading to social withdrawal, inability or refusal to eat, drink, mobilise or speak. The affected individual regresses and is unable to self-care and quite characteristically will resist rehabilitation, worsen with praise or remain entirely passive. This systematic review was aimed at describing clinical features of PRS, current interventions and to summarise some of the nosological aspects of the condition. Without language restriction, an electronic search was conducted in Embase, PsychInfo, Medline, Cochrane library, and PubMed databases yielding 29 articles with a total of 79 cases. We performed a risk of assessment bias using an adapted Newcastle–Ottawa Scale and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. 124 articles were identified, of which 29 were included and these yielded 79 cases. Seventy-six percent of the studies had a low rate of risk of assessment bias (good quality). Our results show that PRS overlaps with several conditions, mainly affects young females aged 7–15 years and has a recovery rate of 78% if diagnosed and treated early but the duration of inpatient treatment may last up to 9.44 months (8.82 SD). The patients had multiple inter-dependent risks. The major predisposing factors included vulnerable premorbid personality and pre-existing mental disorder. Precipitating factors were stressors such as infection and traumatic experiences. Enmeshed parent–child relationship served as a maintaining factor. The themes of treatment approach are essentially rehabilitative: (1) working collaboratively with patient and family, (2) having access to multidisciplinary team, and (3) peer/group supervision. This study has systematically evaluated a large sample of patients with PRS to ascertain its clinical features and the core elements of its treatment. Its key treatment approach is a multi-modal rehabilitative strategy that is compassionate, transparent and inclusive.Electronic supplementary materialThe online version of this article (10.1007/s00787-020-01536-1) contains supplementary material, which is available to authorized users.

Personality disorders characterized by anxiety predict Alzheimer's disease in women: A case-control studies

This research is geared toward the evaluation of current and pre-morbid personality psychopathology in Alzheimer's disease (AD). The study was conducted with four groups who were administered the Personality Diagnostic Questionnaire-4+, mainly in the form of individual interviews. Current measurement: AD Group, 44 female participants (M = 81.36 years); Control Group, 80 female participants from the population at large (M = 75.84 years). Pre-morbid measurement: AD Group Informants (n = 40); Control Group Informants (n = 42). The incidence of all clusters in clinical state are significant, and Cluster B incidence in pre-morbidity is evidenced. Cluster C is highlighted throughout the life course as a predictor. Logistic regression analyses showed that schizotypical, narcissistic, avoidant, obsessive-compulsive, pre-morbid schizotypical, pre-morbid histrionic, and pre-morbid obsessive-compulsive personality disorders, predicted the presence of AD diagnosis, accounting for 49% of the variance. These findings are relevant to research relating personality and psychopathology in Alzheimer's disease.

Analysis of risk factors for antipsychotic-resistant schizophrenia in young patients – A retrospective analysis

Treatment resistant schizophrenia (TRS) is a severely disabling disorder, which decreases dramatically the quality of life and overall functionality, while it increases the rate of hospital admissions and overall healthcare costs. The main objective of this research was to evaluate the risk factors for TRS in a group of patients based on a retrospective analysis. The secondary objective was to design an algorithm for initial evaluation in patients with schizophrenia, in order to detect the candidates at risk for developing TRS. Medical charts and consultation records of all patients aged between 18 and 30, diagnosed with TRS, evaluated during 1-year in our department, were selected for analysis. The most significant risk factors for TRS found in univariate model were younger age at schizophrenia onset, male gender, living in rural areas, co-morbid drug dependence, lower therapeutic adherence, and premorbid personality disorder. Marginally significant were higher Positive and Negative Syndrome Scale (PANSS) scores at previous admissions, higher scores on PANSS negative symptoms sub-scale, and lower educational background. In the multivariate model, TRS was still significantly predicted.

Premorbid Personality Disorders in Male Schizophrenic Patients with or without Comorbid Substance Use Disorder: Is Dual Diagnosis Mediated by Personality Disorder?

Although substance abuse is an important clinical problem in schizophrenic patients, very little evidence explains why these patients use drugs and alcohol. This study therefore aimed to examine whether premorbid personality disorders affect substance abuse. The sample included 40 male schizophrenic patients with and 40 male schizophrenic patients without substance use disorder comorbidity who had applied to Ankara Numune Research and Training Hospital. Each participant and a family member were interviewed in a structured clinical interview that addressed premorbid personality disorders. Altogether, 32 patients (80%) in the group with comorbidity and 28 (70%) in the group without comorbidity had a premorbid personality disorder. Antisocial (35% vs. 0%; p<.001) and borderline (37.5% vs. 5%; p=.001) personality disorders were more often detected in the group with comorbidity, while avoidant (10% vs. 35%; p=.014) and obsessive-compulsive (0% vs. 15%; p=.026) personality disorders were less frequently found in this group. Comparing the group with comorbidity with premorbid personality types, schizophrenic patients with premorbid antisocial personality disorder were more frequently unemployed and hospitalized as well as had an earlier onset age of schizophrenia (p=.034, p=.038 and p=.035, respectively). Schizophrenic patients with premorbid borderline personality disorder had a significantly earlier onset age of substance use (19±5; p=.028). Schizophrenic patients with substance use comorbidity variously differ from those without comorbidity and some of these differences may be associated with premorbid personality disorders.

Functional outcome in major psychiatric disorders and associated clinical and psychosocial variables: A potential cross-diagnostic phenotype for further genetic investigations?

Objectives. Functional outcome has recently become of interest for cross-diagnostic subphenotype approaches in psychiatric genetics. Therefore, it is crucial to know about clinical, demographic and psychosocial variables that correlate with long-term functioning. Unfortunately, there is a lack of studies that directly compare the importance of correlates for functional outcome between different disorders. Methods. Applying regression models to samples of patients with schizophrenia (SZ, n = 238), bipolar disorder (BD, n = 533) and major depressive disorder (MDD, n = 398), we compared the magnitude of association of potential correlates with functional outcome, measured by the Global Assessment of Functioning (GAF) score. Results. Shared correlates for worse functional outcome were poor premorbid functioning, insidious illness onset and poor premorbid work or social adjustment in all three disorders, and negative symptomatology in SZ and BD. Disorder-specific correlates for SZ were longer duration of illness, lower functioning during episodes and being life-time single, for BD substance abuse and suicidality, and for MDD premorbid unemployment and having a premorbid personality disorder. Conclusions. We found different patterns of correlates for long-term functioning in SZ, BD and MDD. Knowledge of these patterns may improve the quality of genetic investigations focussing on functional outcome.

Prevalence and impact of childhood abuse in people with a psychotic illness. Data from the second Australian national survey of psychosis

Child abuse has been associated with risk of mental illness, including schizophrenia and other psychotic disorders and, among those with mental illness, with a more severe clinical profile. Using an extensively characterised and epidemiologically representative sample of 1825 Australians with a psychotic illness aged 18–64 years and in contact with mental health services, we estimated the proportion of individuals with psychotic disorders who self-reported child abuse and examined its relationship with clinical and other characteristics. The prevalence of child abuse in this nationally representative sample of people with psychotic illness was 30.6%. Women were almost three times more likely to report child abuse compared to males (OR, 2.8, 95% CI 2.3–3.4). When adjusted for age at interview and socio-economic status, there was no significant relationship between self-reported child abuse and type of psychosis or course of illness. Participants with child abuse were significantly more likely to have subjective thought disorder, lifetime suicide attempt and premorbid personality disorder (females only) and anxiety (males only). Our findings demonstrate that child abuse is relatively common across the range of psychotic disorders, with an elevated risk for women in particular, compounding the already high burden associated with psychotic illness. Clinicians need to inquire routinely about child abuse in order to develop appropriate treatment plans tailored to individual needs.

One Quintillion Ways to Have PTSD Comorbidity: Recommendations for the Disordered DSM-5

Galatzer-Levy and Bryant (Perspect Psychol Sci 8:651–662, 2013) have calculated the number of ways that Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5; American Psychiatric Association, 2013) posttraumatic stress disorder (PTSD) symptoms can be combined as over 600,000. They concluded that the amount is astounding and the category is rendered amorphous. PTSD often occurs in the context of polytrauma or comorbidity. The epidemiological literature indicates that the most common comorbid conditions in cases of PTSD include major depressive disorder (MDD), chronic pain, neurocognitive disorder due to traumatic brain injury (e.g., mild), and alcohol use disorder, with premorbid personality disorder possible, as well (which we consider as exacerbated due to the traumatic incident at issue, as in borderline personality disorder). We calculated the possible symptom combinations for each of these disorders and then in comorbid combination with PTSD (e.g., PTSD with MDD, but also when all six conditions are present). The number of symptom combinations in full polytrauma involving all six conditions listed is truly astounding, over one quintillion. Also, we reviewed the range of PTSD comorbidities, which adds to the symptom heterogeneity in cases. We make recommendations to prioritize symptoms in disorders as primary (e.g., unique, marker), secondary (e.g., core essential), and tertiary (e.g., common, cross-diagnostic). The latter tertiary type of symptoms in a disorder, if any, should be kept apart in its own criterion. This approach might help make the next version of the DSM more clinically useful both to clinicians and to court.

Demographic features and premorbid personality disorder traits in relation to age of onset and sex in paranoid schizophrenia

Personality disorders in the premorbid period of schizophrenia and particularly in relation to age of onset and sex, seem to be a rather under-researched area. In the present study, 88 patients with paranoid schizophrenia were examined, regarding demographic characteristics and premorbid personality disorder traits, in order to investigate for differences in the premorbid period of the disease, in relation to age of onset and sex. Age cutoff points were set at <30 years and ≥35 years of age for young and late onset groups, respectively. The Structured Clinical Interview for DSM-IV-Patient Edition for Axis I disorders (SCID-P) was used prospectively for diagnoses. Premorbid personality disorder traits were retrospectively assessed by using the Structured Clinical Interview for DSM-IV-Patient Edition for Axis II disorders (SCID-II). Comparisons were performed by applying the two-tailed Wilcoxon rank-sum and the χ2 statistical tests. Young onset patients were characterized by significantly higher proportion of urban birth, single status, more avoidant premorbid personality disorder traits, and less passive-aggressive premorbid personality disorder traits, than late onset counterparts. Differences were more prominently shown in men. Earlier age of onset seems to be associated to increased social inhibition and worse psychosocial adaptation in the premorbid period of paranoid schizophrenia.

Prevalence of premorbid personality disorder and its clinical correlates in patients with delusional disorder

The aim of this study was to investigate the presence of premorbid Personality Disorder (PD) and its relationship with clinical correlates in patients with Delusional Disorder (DD). Eighty-six outpatients with DD whose diagnoses were confirmed using the Structured Clinical Interview for DSM-IV Axis I (SCID-I) Disorders (psychosis module) were evaluated for premorbid PD utilizing the Standardized Assessment of Personality (SAP). Psychopathology was assessed using Module B of SCID-I and the Positive and Negative Syndrome Scale (PANSS); psychosocial functioning was evaluated with the Global Assessment of Functioning scale. Premorbid intelligence was assessed using the Wechsler Adult Intelligence Scale-Third Edition, vocabulary subtest. A sociodemographic-clinical questionnaire was completed. Sixty-four percent of the patients had at least one premorbid PD, the most common being paranoid PD (38.4%), followed by schizoid PD (12.8%). The presence of at least one premorbid PD was significantly associated with higher scores for psychopathology, in particular, on the affective dimension of DD symptoms. However, the presence of premorbid PD was not associated with psychosocial functioning. Each of the premorbid PD was associated with different psychopathological profiles. Premorbid PD is a relevant phenomenon in DD, given its high prevalence and comorbidity, its influence on clinical correlates and its potential ability to predict specific sub-syndromes.

Role of demotivation and affective disorders in apathy in patients with Parkinson's disease without dementia and depression

to assess the role of demotivation and various affective factors in apathy in patients with Parkinson's disease (PD) without dementia and depression. 20 patients and 20 control subjects matched with age, education level, and genre. apathy was assessed by the Apathy evaluation scale (AES) and by a specific scale including a quantitative evaluation of 32 intentional activities and a qualitative assessment of the causes of attribution of restricted activities by a semi-structured interview (GDAS). Four causal attributions were distinguished: E = related to external factors, M = disease symptoms related, C = affective disturbances with preservation of motivation, and D = demotivation. The results were compared to a battery of tests including cognitive evaluation (mini-mental state and Mattis dementia rating scale for global evaluation, selecting reminding test for memory; Stroop test for inhibition, and six element test for planification); affective evaluation (Montgomery & Asberg and Hamilton depression rating scales for depression, emotional disturbances by the Abrams and Taylor scale, the Depression mood scale, and the International picture system), premorbid personality (NEOPI-R), and defensive psychological mechanisms (DSQ-40); functional assessment by a combined scale including the Self-maintenance physical scale and the Instrumental activities of daily living (Lawton) and the Social activities scale (Katz & Lyerly), the Disability assessment scale, and the UPDRS. apathy was found in 25% of the patients according to the AES, but only in 15% according to the GDAS. Scores on cognitive and affective evaluation were higher in patients than in controls but only emotional blunting was correlated to apathy. Some results coud be interpreted in favor of a premorbid personality disorder in patients with PD, but were not correlated to apathy. Causal attribution was M in 38% of cases of reduced activities, D in 30%, E in 22%, and C in 10%. emotional blunting was the main correlate of apathy in PD patients without dementia and depression. Demotivation was the causal mechanism in only 30% of the patients with apathy.

2356 – Case report: autoamputation of the penis in a patient with shizophrenia

Schizophrenia is a psychiatric disorder that often manifests itself as chronic, serious mental illness which primarily affects one's ability to think, coupled with impaired perception of reality, which causes a change in behavior followed by unpleasant sensations. The following case report describes an act of genital self mutilation. An employed, unmarried male suffering from schizophrenia, auto castrated his genitalia during a period of illness. Psychotic patients with delusions (often of religious nature), sexual conflict associated with guilt, past suicide attempts or other self-destructive behavior and depression, severe childhood deprivation, and major premorbid personality disorder, are the group at risk of genital self-amputation. The objective of this case study is to gain a better understanding of the consequences of certain symptoms of schizophrenia, however rare and bizarre they might be.

Empirical redefinition of delusional disorder and its phenomenology: the DELIREMP study

AimsSince Kraepelin, the controversy has persisted surrounding the nature of delusional disorder (DD) as a separate nosological entity or its clinical subtypes. Nevertheless, there has been no systematic study of its psychopathological structure based on patient interviews. Our goal was to empirically explore syndromic subentities in DD. MethodsA cross-sectional study was conducted in 86 outpatients with DSM-IV-confirmed DD using SCID-I. Psychopathological factors were identified by factor analysis of PANSS scores. The association between these factors and clinical variables (as per standardized instruments) was analyzed using uni- and multivariate techniques. ResultsPANSS symptoms were consistent with four factors (Paranoid, Cognitive, Schizoid, and Affective dimensions), accounting for 59.4% of the total variance. The Paranoid Dimension was associated with premorbid paranoid personality disorder, more adverse childhood experiences, chronic course, legal problems, worse global functioning, and poorer treatment adherence and response. The Cognitive Dimension was associated with poorer cognitive functioning, premorbid substance abuse, comorbid somatic diseases, mainly non-prominent visual hallucinations, fewer comorbid depressive disorders, and poorer global functioning. The Schizoid Dimension was associated with being single, a family history of schizophrenia, premorbid personality disorders (largely schizoid and schizotypal), non-prominent auditory hallucinations, and dysthymia. Finally, the Affective Dimension was associated with a family history of depression, premorbid obsessive personality, somatic delusions, absence of reference delusions, tactile and olfactory hallucinations, depressive and anxiety disorders, risk of suicide, and higher perceived stress. ConclusionThe identification and clinical validation of four separate psychopathological dimensions in DD provide evidence toward a more accurate conceptualization of DD and its types.

From narcissistic personality disorder to frontotemporal dementia: a case report.

Premorbid personality characteristics could have a pathoplastic effect on behavioral symptoms and personality changes related to neurodegenerative diseases. Patients with personality disorders, in particular of the dramatic cluster, may present functional frontolimbic abnormalities. May these neurobiological vulnerabilities linked to a premorbid personality disorder predispose or represent a risk factor to subsequently develop a neurodegenerative disorder? Are subjects with personality disorders more at risk to develop a dementia than mentally healthy subjects? This topic is discussed presenting the clinical case of a patient who suffered of a probable Narcissistic Personality Disorder and subsequently developed a clinically diagnosed Frontotemporal Dementia.

Vocally disruptive behavior (VDB) in the institutionalized elderly: A naturalistic multiple case report

Employing a naturalistic multiple case study approach, we investigated the current clinical practice in the treatment and care of VDB among a convenience sample of 85 patients cared for in specialized old age psychiatric clinics and nursing homes in French and German-speaking Switzerland. We wished to clinically characterize VDB patients, to identify common approaches used to treat VDB in everyday practice, and to explore how the efficiency of the interventions employed was judged by the responsible carers. Data were collected by means of a questionnaire. Most patients with VDB in this study had dementia, of whom 75% had at least one current or premorbid psychiatric disorder and 25% had premorbid personality disorder. A majority of patients received multiple psychosocial care interventions that were often judged to be effective, but the potential of psychosocial interventions is underused. Many patients did not receive psychotropic medication specifically targeted at VDB, but about 70% of all prescriptions were judged to have positive effects. Premorbid psychiatric and personality disorders or traits are likely candidates to be entered into the etiopathogenic equation of VDB and set a new frame for approaches used to treat these underlying disorders.

Gender differences in delusional disorder: Evidence from an outpatient sample

Our objective was to study gender differences in delusional disorder (DD), by comparing potential risk factors, clinical correlates, illness course characteristics, and functionality. The sample was composed of 86 outpatients with DD (according to the SCID-I for DSM-IV criteria). The following assessment instruments were used service use and demographic questionnaires, Standardized Assessment of Personality (SAP), the Positive and Negative Symptom Scale (PANSS), Montgomery-Asberg Depression Rating Scale (MADRS), Mini-Mental State Examination (MMSE), Mini International Neuropsychiatry Interview (MINI), Sheehan Disability Inventory (SDI), and the Global Assessment of Functioning (GAF) scale. The female-to-male ratio was 1.6:1. Men were more likely to be single, while women were more likely to be widows. Men had a greater frequency of schizoid and schizotypal premorbid personality disorders and of premorbid substance abuse. There were no differences for other risk factors (immigration, deafness, late onset, other personality disorders, and family history). Men were younger at onset and more frequently had acute onset of the disorder. Men had more severe symptoms (higher score on the global or separate PANSS scales). There were no gender differences for the remaining symptomatological variables (types of DD, presence and severity of depression, presence of hallucinations, severity of global cognitive functioning and presence of axis I comorbidity). Global and partial (work, family, and social) functioning was significantly poorer among men. Course type and consumption of resources appeared to be similar. We conclude that men with DD had significantly more severe symptoms and worse functionality. They also had a higher frequency of schizoid and schizotypal premorbid personality disorders and premorbid substance abuse.

Un estudio empírico de los correlatos psicosociales y clínicos del trastorno delirante: el estudio DELIREMP

We aim to describe psychosocial and clinical correlates of delusional disorder (DD) and its types. This approach is important because most knowledge on DD does not come from empirical data collected using a validated systematic research method.A cross-sectional study was conducted in a sample of 86 patients fulfilling DSM-IV criteria for DD as established using the SCID-I. Variables were evaluated using a systematic methodology and standardized instruments, and included possible psychosocial risk factors (low socioeconomic status or social isolation, immigration, sensory deficits, older age at onset), family history of psychiatric disorders and premorbid personality (SAP), psychotic psychopathology (PANSS), depressive syndrome (MADRS), global cognitive functioning (MMSE), axis I comorbidity (MINI) and other clinical aspects such as global functionality (GAF), and disability (SDI). A sociodemographic and clinical questionnaire was also completed.The mean age at onset was 39.6 years and 61.6% of the cases were female. The most frequent DD types were persecutory (59.3%) and jealous (22.1%). Nearly 21% had a family history of schizophrenia and 17.4% had DD (significantly higher among those with the jealous subtype). Sixty-four percent had a premorbid personality disorder (38.4% paranoid, 12.8% schizoid). The grandiose type was significantly associated with higher scores on the PANSS positive subscale and the mixed type with lower scores on the PANSS negative subscale. Depression affected 45.3% of subjects (mainly mild depression) and 45.3% had hallucinations (20.9% tactile, 16.3% olfactory), which were more common among somatic cases. The mean MMSE was 27.6±2.5 suggesting a preserved cognitive function. Mean GAF was 63.9±11.3 indicating a moderate degree of disability, which was significantly worse amongst grandiose cases.This study provides unique empirical and reliable evidence on the real psychosocial, clinical, and psychopathological correlates of DD and its types.

Do premorbid personality disorders predict adult alcoholism? Results from a Danish Longitudinal High Risk Study

Do premorbid personality disorders predict adult alcoholism? Results from a Danish Longitudinal High Risk Study

Premorbid adjustment and previous personality in schizophrenic patients

Psychosocial adjustment and premorbid personality are two factors that are frequently studied in order to elucidate the etiopathogenesis of schizophrenia. Premorbid adjustment alterations and personality disorders (principally those of the schizophrenia spectrum) have been considered vulnerability elements or have been linked with the early manifestations of a disease that is still underdeveloped (hypothesis of neurodevelopment). In this paper we review the literature. We also studied the relationship between premorbid adjustment (PAS scale) and previous personality disorders (SCID-II) in a sample of 40 patients with schizophrenia (DSM-III-R, DSM-IV, CIE-10), and statistically correlated them. The results show that premorbid adjustment correlates with avoidant, schizotypal and schizoid personality disorders: the more personality pathology found, the poorer is the premorbid psychosocial adjustment. Premorbid adjustment positively correlates with histrionic personality traits. The pathological traits of schizotypal and schizoid personalities account for up to 77% of the variance of the total premorbid adjustment in schizophrenic patients. Conclusion: The degrees of premorbid adjustment in schizophrenia are related to the different premorbid personality disorders of schizophrenic patients, which are mainly those most genetically related with schizophrenia, that is, the spectrum of the schizophrenia.
