Psychopathology factors in first-episode affective and non-affective psychotic disorders.

BACKGROUND: Since the onset, prevalence, and course of specific psychopathological features rarely have been analyzed simultaneously from the start of dissimilar psychotic illnesses, we compared symptom-clusters in first-episode DSM-IV affective and non-affective psychotic disorders. METHODS: Subjects (N=377) from the McLean-Harvard First Episode Project hospitalized for first-lifetime primary psychotic illnesses were followed prospectively for 2 years to verify stable DSM-IV diagnoses. We ascertained initial symptoms from baseline SCID and clinical assessments, applying AMDP and Bonn psychopathology schemes systematically to describe a broad range of features. Final consensus diagnoses were based on intake and follow-up SCID assessments, family interviews, and medical records. Factor-analytic methods defined first-episode symptom-clusters (Factors), and multiple-regression modeling related identified factors to initial DSM-IV diagnoses and to later categories (affective, non-affective, or schizoaffective disorders). RESULTS: Psychopathological features were accommodated by four factors: I represented mania with psychosis; II a mixed depressive-agitated state; III an excited-hallucinatory-delusional state; IV a disorganized-catatonic-autistic state. Each factor was associated with characteristic prodromal symptoms. Factors I and III associated with DSM-IV mania, II with major depression or bipolar mixed-state, III negatively with delusional disorder, IV with major depression and negatively with mania. Factors I and II predicted later affective diagnoses; absence of Factor I features predicted non-affective diagnoses, and no Factor predicted later schizoaffective diagnoses. CONCLUSION: The findings contribute to descriptive categorizations of psychopathology from onset of dissimilar psychotic illnesses. This approach was effective in identifying and subtyping affective psychotic disorders early in their clinical evolution, but non-affective and schizoaffective conditions appear to be more complex and unstable.

Neuropsychological differences between first-admission schizophrenia and psychotic affective disorders.

OBJECTIVE: The study compared the neuropsychological functioning of patients with first-admission schizophrenia with that of patients with first-admission psychotic affective disorders. METHOD: Data came from the Suffolk County Mental Health Project, an epidemiological study of first-admission psychotic disorders. Subjects with a diagnosis of schizophrenia (N=102) and psychotic affective disorders, including bipolar disorder with psychotic features (N=72) and major depressive disorder with psychotic features (N=49), were compared on a battery of neuropsychological tests administered 2 years after the index admission. RESULTS: Subjects with schizophrenia performed worse than those with the psychotic affective disorders, even after adjusting the results for differences in demographic characteristics and general intellectual functioning. The most consistent differences were on tests of attention, concentration, and mental tracking. The two psychotic affective disorder groups were indistinguishable in performance on the neuropsychological tests. CONCLUSIONS: Even early in its course, schizophrenia is distinguishable from psychotic affective disorders by global and specific neuropsychological deficits. These deficits might contribute to the disability and poor outcome associated with schizophrenia in the mid- and long-term course.

Mood-congruent vs. mood-incongruent psychotic symptoms in affective psychotic disorders.

This review of the literature on the importance of congruence of mood to identify nosological sub-categories among the affective disorders showed the limited value of this concept. The reported prevalence rates of affective psychoses with mood-congruent, mood-incongruent and a combination of these symptoms vary widely among the different studies. This categorization seems neither to identify sub-groups with distinct demographic and onset characteristics nor to predict course and outcome. Furthermore, the ambiguity of the guidelines and the different use of this concept in the studies increase the confusion. The only heuristic value of the use of this concept seems to be its prediction of change of diagnosis. The authors suggest eliminating the concept of mood congruence from the categorization of affective disorders and, if not, to state more concise and explicit guidelines for research and clinical use.

Two-year syndromal and functional recovery in 219 cases of first-episode major affective disorder with psychotic features.

OBJECTIVE: Psychotic affective disorders are the most prevalent idiopathic psychoses, but their outcome from onset has rarely been studied. In this study, the authors determined the rate and latency of syndromal recovery and rates of functional recovery after first lifetime hospitalization in patients with first-episode psychotic affective disorders. METHOD: From first lifetime hospitalization in 1989-1996, 219 patients with a DSM-IV psychotic affective illness were assessed at intervals over 24 months. Time to syndromal recovery (no longer meeting DSM-IV episode criteria) was assessed by survival analysis, and functional recovery (regaining baseline vocational and residential status) was rated. Factors associated with recovery were identified by bivariate and multivariate methods. RESULTS: By 3, 6, 12, and 24 months after first hospitalization, syndromal recovery was attained by 65.1%, 83.7%, 91.1%, and 97.5%, respectively, of subjects. Time to syndromal recovery (6.1 weeks to 50% of subjects recovered) was shorter for patients who had bipolar disorder, were married, were age 30 or older at onset, lacked comorbidity, required relatively brief hospitalization, and received fewer medicines. Functional recovery by 6 (30.4%) and 24 months (37. 6% of patients) was 2.6-2.7 times less likely than syndromal recovery; 63.1% of those recovering syndromally did not recover functionally by 2 years. Functional recovery was associated with older age at onset and shorter hospitalization. Annual recovery rates remained stable as mean hospital length of stay decreased 3. 6-fold over the 8-year study period. CONCLUSIONS: Syndromal recovery was attained by most psychotic affective disorder patients soon after hospitalization, but only one-third recovered functionally by 24 months. The findings suggest that these very common psychotic illnesses can carry a grave functional prognosis from the initial episode and first hospitalization.

The significance of psychotic affective disorders.

A study of 253 patients with primary and secondary affective disorders disclosed that psychotic features were more frequent among bipolar patients. Except for more frequent psychiatric hospitalization among unipolar patients with psychotic features, no demographic, family history, or parental home variable was found to distinguish between those with and without psychotic features. Chance variation probably accounted for the few symptoms whose frequencies were different depending on the presence or absence of psychotic features. The results failed to support the validity of a classification of affective disorders based on the presence or absence of psychotic features.

The association between lithium carbonate and smooth pursuit eye tracking among first-episode patients with psychotic affective disorders.

The association between treatment with lithium carbonate and smooth pursuit eye tracking performance was investigated in first-episode patients with psychotic affective disorders. The horizontal pursuit performance of patients with major depression and bipolar disorder who were receiving lithium carbonate was contrasted with that of patients not receiving lithium carbonate. In addition, the accuracy and quality of pursuit eye tracking was examined in bipolar patients whose lithium status changed from the time of initial testing to the time of retest 10 months later. For the combined group of depressed and bipolar patients, treatment with lithium carbonate was not associated with worse pursuit performance. Bipolar disordered patients on lithium did not differ in tracking proficiency from those not on lithium; bipolar patients whose lithium status changed from intake to retest also did not display a significant change in pursuit performance.

Adult quality of life and associated factors in adolescent onset schizophrenia and affective psychotic disorders.

BACKGROUND: Subjects in treatment for affective disorders are usually less satisfied with life compared to subjects with schizophrenia. AIMS: The aims of this study were to compare subjective quality of life (QoL) at adult age of adolescent onset psychotic disorders and analyse associated factors. METHOD: Fifty-three patients with adolescent onset psychotic disorders were followed up at age 25, diagnostically re-evaluated according to the DSM-IV and assessed with the Positive and Negative Symptoms Scale, the Strauss-Carpenter Scale and the Lancashire Quality of Life Profile. RESULTS: Subjects diagnosed with schizophrenia or schizoaffective disorder (n = 27) experienced significantly lower overall QoL than subjects with psychotic mood disorders (n = 26). Overall QoL was strongly associated to depressed mood (R2 = 0.49) in the schizophrenia group and to degree of employment (R2 = 0.39) in the mood disordered group. CONCLUSION: Depression is a major concern in the evaluation and treatment of patients with schizophrenia, while vocational support seems particularly important after an episode of psychotic mood disorder.

Shape differences in the corpus callosum in first-episode schizophrenia and first-episode psychotic affective disorder.

OBJECTIVE: The corpus callosum, the largest white matter tract in the brain, is a midline structure associated with the formation of the hippocampus, septum pellucidum, and cingulate cortex, which have been implicated in the pathogenesis of schizophrenia. Corpus callosum shape deformation, therefore, may reflect a midline neurodevelopmental abnormality. METHOD: Corpus callosum area and shape were analyzed in 14 first-episode psychotic patients with schizophrenia, 19 first-episode psychotic patients with affective disorder, and 18 normal comparison subjects. RESULTS: No statistically significant corpus callosum area differences between groups were found, but there were differences in the structure's shape between the patients with schizophrenia and the comparison subjects. A correlation between width and angle of the corpus callosum was found in patients with affective disorder. CONCLUSIONS: Corpus callosum shape abnormalities in first-episode psychotic patients with schizophrenia may reflect a midline neurodevelopmental abnormality.

The New York High-Risk Project. Psychoses and cluster A personality disorders in offspring of schizophrenic parents at 23 years of follow-up.

BACKGROUND: We herein present lifetime prevalence rates of psychoses and DSM-III-R cluster A personality disorders in sample A of the New York High-Risk Project, a prospective study following offspring of parents with schizophrenia (HRSz subjects) and affective illness (HRAff subjects) and of psychiatrically normal parents (NC subjects) from midchildhood to adulthood. METHODS: We interviewed the offspring in adulthood with the Schedule for Affective Disorders and Schizophrenia, Lifetime Version, for Axis I disorders and the Personality Disorder Examination for Axis II disorders. RESULTS: Lifetime prevalence rates (+/- SE) of schizophrenia and unspecified psychosis were 11.1% +/- 4.3% and 5.6% +/- 3.1%, respectively, in the HRSz group and 0% in the HRAff and NC groups. Rates of schizoaffective disorder subclassified as mainly schizophrenic, however, were highest in the HRAff group. Rates of psychotic affective disorders did not differ between the HRSz and other groups. Age-corrected morbidity risks were similar to lifetime prevalence rates. Rates of the three cluster A personality disorders did not differ among the groups, but the combined rate was greater in the HRSz and HRAff groups than in the NC group. CONCLUSIONS: Our data strongly support a specific familial liability to narrowly defined schizophrenia that is not shared by families of probands with affective disorder. Schizoaffective disorder and cluster A personality disorders, however, occur in families of both schizophrenic probands and probands with affective disorder. Psychotic affective disorders, which are not increased in HRSz subjects, do not appear to be an expression of the liability to schizophrenia.

Symptomatology and social inference: a theory of mind study of schizophrenia and psychotic affective disorder.

INTRODUCTION: There is evidence that certain patients with schizophrenia have deficits in theory of mind (ToM) capabilities. It is, however, unclear whether these are symptom or diagnosis-specific. METHODS: A ToM hinting task was given to 15 patients with a DSM-IV diagnosis of schizophrenia, 15 patients with affective disorder and 15 healthy controls. Severity of the current psychopathology was measured using the Krawiecka standardised scale of psychotic symptoms (Krawiecka, Goldberg, & Vaughan, 1977); IQ was estimated via the Ammons and Ammons Quick Test (Ammons & Ammons, 1962). RESULTS: The group with schizophrenia performed significantly worse than the affective and control groups. Poor performance on the hinting task was found to be significantly related to the presence of positive symptoms (instead of negative ones) and specifically related to delusions and hallucinations. These findings remained when covariance for potentially confounding variables was applied. CONCLUSIONS: Individuals with high levels of delusions and hallucinations performed significantly worse on this ToM task, regardless of diagnosis, implying ToM impairment is not exclusive to schizophrenia but is evident in other forms of psychosis. Between-group analyses showed the schizophrenia group had a significantly poorer performance on this task than the others.

Medication treatment in first-admission patients with psychotic affective disorders: preliminary findings on research-facility diagnostic agreement and rehospitalization.

The discharge medications of 101 Suffolk County subjects with facility and/or research diagnoses of affective disorder were ascertained. Rehospitalization was recorded for a 6-month follow-up period. Twenty-three of 31 patients (74.2%) with a facility diagnosis of depressive disorder were prescribed antidepressants, and 21 of 36 patients with a facility diagnosis of bipolar disorder (58.3%) were prescribed lithium. When research and facility diagnoses concurred, 84.2% of depressed patients were prescribed antidepressants, and 66.7% of bipolars were given lithium. The percentages were lower when the two diagnoses were discrepant. The results for diagnostic congruence were independent of demographic variables, length of stay, and premorbid functioning. Patients prescribed diagnosis-specific medications had a lower rate of rehospitalization (7.3%) than those not prescribed such medications (22.2%). The findings suggest that such medications are prescribed in the more unambiguous cases of affective disorders and are important (with or without antipsychotic treatment) in preventing rehospitalization.

A Canadian programme for early intervention in non-affective psychotic disorders.

OBJECTIVES: To provide a brief overview of the development of clinical services and research for early intervention in psychotic disorders in Canada; to describe components of a comprehensive clinical/research programme for nonaffective psychotic disorders; and to present a summary of results of clinical and social outcomes achieved. METHOD: This is a descriptive paper providing some details of how clinical services are being developed in Canada and concentrating on one particular early intervention programme, Prevention and Early intervention Programme for Psychoses (PEPP) London, Ontario, which is using a historical control design to evaluate the impact of an assertive approach to community case detection. Components of a phase-specific treatment programme and early case detection are described followed by results based on clinical and psychosocial data collected according to a defined protocol. RESULTS: One year outcome for patients treated in PEPP shows use of low dose, pre-dominantly novel antipsychotics and high (81.5%) retention and remission (75%) rates. Highly significant improvements were also reported for self-rated quality of life and cognition. Duration of untreated psychosis (DUP) and premorbid adjustment were associated with improvement in positive and negative symptoms, respectively. Systemic changes to improve access to the service resulted in substantial increases in number of cases treated and a> 50% decline in DUP. CONCLUSIONS: Phase-specific treatment approach and case identification strategies to reduce delay in treatment are likely to substantially improve outcome in nonaffective psychotic disorders compared with what has been reported with traditional approaches.

COMT genetic variation confers risk for psychotic and affective disorders: a case control study.

BACKGROUND: Variation in the COMT gene has been implicated in a number of psychiatric disorders, including psychotic, affective and anxiety disorders. The majority of these studies have focused on the functional Val108/158Met polymorphism and yielded conflicting results, with limited studies examining the relationship between other polymorphisms, or haplotypes, and psychiatric illness. We hypothesized that COMT variation may confer a general risk for psychiatric disorders and have genotyped four COMT variants (Val158Met, rs737865, rs165599, and a SNP in the P2 promoter [-278A/G; rs2097603]) in 394 Caucasian cases and 467 controls. Cases included patients with schizophrenia (n = 196), schizoaffective disorder (n = 62), bipolar disorder (n = 82), major depression (n = 30), and patients diagnosed with either psychotic disorder NOS or depressive disorder NOS (n = 24). RESULTS: SNP rs2097603, the Val/Met variant and SNP rs165599 were significantly associated (p = 0.004; p = 0.05; p = 0.035) with a broad "all affected" diagnosis. Haplotype analysis revealed a potentially protective G-A-A-A haplotype haplotype (-278A/G; rs737865; Val108/158Met; rs165599), which was significantly underrepresented in this group (p = 0.0033) and contained the opposite alleles of the risk haplotype previously described by Shifman et al. Analysis of diagnostic subgroups within the "all affecteds group" showed an association of COMT in patients with psychotic disorders as well as in cases with affective illness although the associated variants differed. The protective haplotype remained significantly underrepresented in most of these subgroups. CONCLUSION: Our results support the view that COMT variation provides a weak general predisposition to neuropsychiatric disease including psychotic and affective disorders.

The prevalence of personality disorders, psychotic disorders and affective disorders amongst the patients seen by a community mental health team in London.

BACKGROUND: There is a lack of information regarding the prevalence and co-occurrence of personality disorders, psychotic disorders and affective disorders amongst patients seen by community mental health teams. This study aims to describe the population of patients served by a community mental health team in South London in terms of demographic and clinical characteristics. METHOD: Computerised hospital records and keyworkers' caseloads were used to identify 193 patients. The Standardised Assessment of Personality was used to assess personality disorders and the Operationalised Criteria Checklist was used to assess psychotic and affective disorders. RESULTS: Fifty-two per cent of patients met the criteria for one or more personality disorders, 67 % of patients had a psychotic illness and 23 % had a diagnosis of a depressive disorder. Community psychiatric nurses (CPNs) mainly saw patients with psychotic illnesses. The non-psychotic patients seen by CPNs had extremely high rates of personality disorder. Patients seen by psychiatrists and psychologists had significantly lower rates of personality disorder. CONCLUSIONS: The prevalence of personality disorder is high amongst patients seen by community mental health teams. Possible explanations for this are presented and implications for community care are discussed.

Serum iron and ferritin in acute neuroleptic akathisia.

Acute akathisia is a common and disturbing side effect of classic antipsychotic medication. Some evidence suggests a role for iron deficiency in chronic and tardive akathisia. In acute akathisia, however, the data are contradictory. Serum iron and ferritin levels of 33 inpatients with acute akathisia during classic neuroleptic medication were compared with those of 23 patients on classic neuroleptics without this side effect. Akathisia was rated by means of the Hillside Akathisia Scale. The groups were balanced for age (mean 38.5+/-14.5), medication (butyrophenone- and phenothiazine-derived neuroleptics) and diagnosis (schizophrenia, schizoaffective disorder, psychotic affective disorder). Patients with acute akathisia had significantly lower serum ferritin levels than the patients in the control group. However, the ferritin (56. 94+/-39.54 ng/ml) and iron (88.52+/-40.0 mg/dl) levels in these patients were within the normal range (ferritin 30-300 ng/dl, iron 80-180 mg/dl). No correlations between serum iron or ferritin and akathisia ratings could be found. Although some reduction in serum ferritin was found in patients with acute akathisia compared to patients without akathisia, the difference was small and the ferritin levels were within the range of the normal population. These findings suggest a minor role for iron deficiency in acute akathisia.
