At the present time, neuroleptics are indicated for the treatment of acute psychotic states as well as Tourette's syndrome in children and adults. Neuroleptics may have a useful role in the attenuation of problem behaviors, such as stereotypies, hyperactivity, self-injury, and aggressive outbursts in infantile autism, pervasive developmental disorder NOS, and mental retardation, but they do not improve the underlying condition. Neuroleptics are not the agents of first choice for treatment of hyperactivity or aggression in children who do not have major developmental handicaps. Common and troublesome side effects associated with neuroleptic use in children and adolescents include sedation, extrapyramidal symptoms, and withdrawal dyskinesias; therefore, close monitoring is required. Neuroleptics should be used cautiously and only as an adjunct to other nonpharmacologic interventions.

Clinicians who deal with psychotic patients see individuals whose illness is similar to schizophrenia, but whose symptoms are less florid, and deterioration less severe, than in schizophrenia. The diagnosis of atypical psychosis or psychotic disorder NOS is not satisfactory since it lumps disparate conditions together, whereas the term "paraphrenia" can include such illnesses. Paraphrenia is a well-established concept that was ignored in the DSM-III and the DSM-III-R and may be excluded from the ICD-10. There is a need to re-establish the diagnosis, for accurate diagnostic purposes and for future research of the paranoid/delusional disorders.

The relationship between DSM-III-R schizophreniform disorder, delusional disorder (DD) and psychotic disorder not otherwise specified (PD-NOS) and schizophrenia and affective illness (AI) remains uncertain. We explore this question in the Roscommon Family Study by examining symptoms, outcome and patterns of psychopathology in relatives. Probands were selected from a population-based case registry in the west of Ireland with an ICD-9 diagnosis of schizophrenia or AI. Personal interviews were conducted with 88% of traceable, living probands, a mean of 16 years after onset, and 86% of traceable, living first-degree relatives. Best-estimate diagnoses were made at follow-up. Schizophreniform disorder, DD and PD-NOS constituted 6.4%, 2.8% and 7.5%, respectively, of all probands with a registry diagnosis of schizophrenia. Probands with schizophreniform disorder had prominent positive psychotic symptoms, negligible negative symptoms and a good outcome, comparable to that seen in AI probands. Their relatives had an excess risk of schizophrenia spectrum illness but not AI. Probands with DD had prominent delusions but no other psychotic symptoms, few negative symptoms, fair to good outcome and an increased risk in relatives for alcoholism. Probands with PD-NOS had both moderate positive and negative psychotic symptoms, a poor to fair outcome and a substantially elevated risk in relatives of schizophrenia and schizophrenia spectrum disorders but not AI.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this study was to investigate the concepts of reactive and hysterical psychoses and how they are classified in standardized diagnostic systems. To this end we identified all of the patients who had been admitted to a psychiatric in-patient unit and diagnosed as suffering from psychogenic psychosis, reactive psychosis, hysterical psychosis or hysteria, using ICD-9 criteria. The case notes of these patients were then re-examined and diagnoses reached using DSM-III-R, DSM-IV and ICD-10 criteria and the Present State Examination (PSE)/CATEGO computer program. The objective of this study was to evaluate the agreement between the diagnoses of reactive and hysterical psychosis obtained using ICD-9 criteria with those obtained using the DSM-III-R, DSM-IV, ICD-10 and PSE diagnostic systems. A total of 67 case notes were identified in which the above diagnoses had been made: 27 cases with ICD-9 'hysteria' and 26 cases with 'other reactive and not otherwise specified psychoses'. Using the DSM-III-R criteria, 27 cases were diagnosed as psychotic disorder NOS, 12 as brief reactive psychosis and 11 as bipolar disorder. Using the DSM-IV criteria, 21 cases were diagnosed as psychotic disorder NOS, 11 as mood disorder, 7 as brief disorder without stressor, and 12 as brief disorder with stressor. Using the ICD-10 criteria, 18 cases were diagnosed as unspecified non-organic psychosis, 12 as mood disorder, 10 as acute and transient psychotic disorder without stressor and 13 as acute and transient psychotic disorder with stressor. Using the PSE/CATEGO program, the most common diagnoses were class 'S' schizophrenia (17), class 'P?' uncertain psychosis (16) and class 'M+' mixed and manic affective disorder (11). Using the kappa coefficient a very low level of agreement was found between ICD-9 'hysteria' and 'other reactive and non-specified psychoses' and the corresponding categories of DSM-III-R and the PSE/CATEGO program. We concluded that, although DSM-III-R provides operational criteria for brief reactive psychosis, and DSM-IV and ICD-10 provide such criteria for brief or acute psychotic disorder, these bear little relationship to the original concept of the disorder. The PSE/CATEGO program provides a very systematic approach to symptomatology, but the diagnostic classes have little clinical usefulness.

Anticipation is a genetic phenomenon wherein age of disease onset decreases and/ or severity increases in successive generations. Anticipation has been demonstrated for several neuropsychiatric disorders with expanding trinucleotide repeats recently identified as the underlying molecular mechanism. We report here the results of an analysis of anticipation performed with multiplex families segregating schizophrenia. Thirty-three families were identified through the NIMH Genetics Initiative that met the following criteria: had at least two affected members in successive generations and were not bilineal. Affectation diagnoses included schizophrenia, schizoaffective disorder-depressed, and psychosis NOS. Additional analyses included the Cluster A personality disorders. Three indices of age of onset were used. Disease severity was measured by several different indices. Four sampling schemes as suggested by McInnis et al. were tested, as well as additional analysis using pairs ascertained through the parental generation. Anticipation was demonstrated for age of onset, regardless of the index or sampling scheme used (P<0.05). Anticipation was not supported for disease severity. Analyses that took into account drug use and diminished fecundity did not affect the results. While the data strongly support intergenerational differences in disease onset consistent with anticipation, they must be viewed cautiously given unavoidable biases attending these analyses.

We studied factors contributing to an increased risk of PPD positive status among 147 inpatients dually diagnosed for mental illness and substance abuse in a large urban hospital. Ninety-three percent (N = 137) were tested for PPD on admission. The rate of positive PPDs was 30.7%. Significant correlates of PPD positive status were the diagnosis of schizophrenia/psychosis NOS (p < .05), and crack cocaine use in the 30 days prior to admission (p < .01). A multiple logistic regression revealed a relative risk of 3.53 (p < .005) for PPD positive status for the crack using group and a relative risk of 2.16 (p < .06) for PPD positive status for the schizophrenic group. Reasons for why patients whose primary drug of abuse is crack cocaine and those whose diagnosis is schizophrenia/psychosis NOS may be at an increased risk for exposure to tuberculosis are discussed as are the implications for public health.

A pattern of negative symptoms associated with a high rate of ongoing brain and ventricular instability has been described in a cohort of schizophrenia spectrum probands (patients with schizophrenia, schizoaffective disorder depressed and bipolar, and psychosis NOS) (Garver, D.L., Nair, T.R., Christensen, J.D., Holcomb, J., Ramberg, J., Kingsbury, S., 1999. Differential patterns of premorbid functioning, symptoms and neuroleptic response in stable and unstable ventricular-volume schizophrenia. Neuropsychopharmacology 20, in press). The present study contrasts the prevalence of negative symptoms in first- and second-degree relatives of probands with unstable ventricle volume (UnsVV) and stable ventricle volume (SVV). One hundred and sixteen first- and second-degree relatives of 10 probands were interviewed using the SANS, the 'Characterization of Course: "Pattern of Symptoms"' [from Comprehensive Assessment of Symptoms and History (CASH)], SCID and SCID-II by interviewers blind to the status of the proband. Thirty-five of the 116 family members met DSM-IV criteria for schizophrenia, SA depressed, 'Cluster A' of the SCID-II (paranoid, schizotypal, schizoid personality disorder), psychosis NOS, or psychotic affective disorder. These 35 family members were defined as falling within a 'schizophrenia spectrum' as described by Farmer, A.E., McGuffin, P., Gottesman, I.I., 1987. Arch. Gen. Psychiatry 44, 634-641, but with the addition of DSM-IV affective psychosis. On that basis, the 35 members were considered 'affected family members' (AFMs). The remaining 81 family members were considered unaffected. The 'predominant symptoms of illness' (during the past 2-3 years) for 25 of the 35 AFMs could be characterized according to the 'Patterns of Symptoms' derived from the CASH. Twenty-five of the 35 AFMs were found to maintain a predominant symptom pattern during the course of illness, which could be characterized according to the 'Pattern of Symptoms' as 'predominantly positive' or 'predominantly negative'. Three of the probands had UnsVV; seven had SVV. Of the 35 AFMs, 11 were related to the UnsVV probands, and 24 were relatives of the SVV probands. The nine rated AFMs of the UnsVV probands showed a trend toward higher SANS scores (7.3 +/- 5.1) (mean +/- s.d.) than the 20 rated AFMs of SVV probands (4.3 +/- 5.1) (p = 0.08) at the time of the interview. Eighty-three per cent (eight of 10) of rated affected pedigree members of the pedigrees delineated by probands with UnsVV probands had a predominantly negative symptom course of illness, and 96% (23 of 24) of rated affected pedigree members of the pedigrees with SVV probands had a predominantly positive symptom course of illness during the preceding 2-3 years (p = 0.002). None of the 12 rated affected pedigree members within pedigrees having UnsVV probands were married at the time of the interview; 45% (14 of 31) of affected pedigree members having SVV probands were married (p = 0.004). A psychiatric disorder, characterized by unstable cerebral ventricles and predominant negative symptoms (including avoidance/failure of marital relationships) appears symptomatically to breed true in pedigrees containing schizophrenia-like illnesses.

There is a high comorbidity between eating disorders and substance dependence. The sequence of illness may indicate differences in the underlying pathology and could reflect different etiologies and treatment. The present study subjects were 218 inpatients and outpatients with diagnoses of anorexia nervosa binge-purge type (AN-BP), bulimia nervosa (BN), and eating disorder NOS (ED-NOS). Of these 218 patients, 38 had substance dependence predating the eating disorder (SDED), 71 had an eating disorder predating the substance dependence (EDSD), and 109 had only an eating disorder (ED-only). All subjects were administered the Structured Clinical Interview for DSM-III-R, Patient Edition With Psychotic Screen (SCID-P). EDSD patients had an earlier onset of the eating disorder than SDED patients and had the greatest prevalence of comorbid pathology. SDED patients were dependent on more substances. We conclude that the sequence of development of the eating disorder and substance dependence in eating disorder patients influences the amount of comorbid psychopathology. Clinical implications and future research are discussed.

We previously reported an association of DRD4 exon3 long allele variants with delusional symptomatology independently from diagnoses. The aim of this investigation was to study DRD4 in major psychoses and to test the association in a larger sample. We studied 2,011 inpatients affected by bipolar disorder (n = 811), major depressive disorder (n = 635), schizophrenia (n = 419), delusional disorder (n = 104), psychotic disorder not otherwise specified (n = 42), and 601 healthy controls. A subsample of 1,264 patients were evaluated using the OPCRIT checklist and differences of symptomatology factor scores among genetic variants were assessed using one-way analysis of variance (ANOVA). DRD4 allele and genotype frequencies in bipolars, schizophrenics, delusionals, and psychotic NOS were not significantly different from controls; major depressives showed a trend toward an excess of DRD4*Short and DRD4*Short/Short variants versus controls. The ANOVA on factor scores in the whole subsample of 1,264 subjects showed a significant difference on delusion factor in allele analysis (P = 0.007), and in genotype one (P = 0.018), with DRD4*Long containing variants associated with severe symptomatology. The analysis in the replication subjects only (n = 803) showed a trend in the same direction, though not reaching the significance level. This analysis in an enlarged sample suggests that DRD4*Long alleles exert a small but significant influence on the delusional symptomatology in subjects affected by major psychoses.

Serotoninergic neurotransmitter systems have been implicated in the pathogenesis of major psychoses. A functional polymorphism (5-HTTLPR) in the upstream regulatory region of the gene (SLC6A4) has been associated with a number of psychiatric disturbances, but conflicting replication followed. The aim of this study was to investigate the possibility that the 5-HTTLPR might be associated with major psychoses. One thousand, eight hundred and twenty inpatients (789 bipolars, 667 major depressives, 66 delusionals, 261 schizophrenics, 37 psychotics not otherwise specified-NOS) and 457 control subjects were included in this study. A subsample of 1235 patients (523 bipolars, 359 major depressives, 259 schizophrenics, 66 delusionals, 28 psychotic NOS) were evaluated for lifetime psychotic symptomatology using the Operational Criteria for Psychotic illness (OPCRIT) checklist. The subjects were also typed for 5-HTTLPR variants using PCR techniques. 5-HTTLPR allele frequencies were not significantly different between controls and bipolars, major depressives, schizophrenics, delusionals and psychotic NOS; genotype analysis also did not show any association. The analysis of symptomatology did not show significant differences. Consideration of possible stratification factors such as sex and age of onset did not significantly influence results. 5-HTTLPR variants are not therefore a liability factor for major psychoses or for major psychoses symptomatology.
