Borderline schizophrenia is held to be a valid entity that should be included in the DSM-III. It is a chronic illness that may be associated with many other symptoms but is best characterized by perceptual-cognitive abnormalities. It has a familial distribution and a genetic relationship with schizophrenia. The term schizotypal personality is an acceptable alternative to borderline schizophrenia, but given the apparent genetic relationship with schizophrenia, and given that we are dealing with a vulnerability to episodic symptoms more than personality traits, we prefer the older term.

Although emotional blunting has always been considered a core symptom of schizophrenia, it has been excluded from recently developed sets of diagnostic criteria because of its alleged unreliability. The authors describe a brief rating scale for emotional blunting that is highly reliable, predicts short-term treatment response, and discriminates between patients with affective disorder and schizophrenia. They suggest that this scale will permit restoration of the important criterion of emotional blunting to modern diagnostic systems, including that proposed for DSM-III.

One hundred ninety cases of lithium carbonate use in children and adolescents are reviewed and divided by the authors according to DSM-II criteria into major affective disorders, behavior disorders of childhood and adolescence, and schizophrenia, childhood type. Of these 190 cases, only 46 cases were described in detail. In this group of 25 males and 21 females, aged 3 to 19, there were 30 positive responses to lithium carbonate. A family history of diagnosed manic-depressive illness was reported in only eight cases, while 19 had a family history of other psychiatric disorders. We were impressed by the affective component, irrespective of diagnosis, in youngsters responding to lithium carbonate and by the use of the drug despite multiple neurological problems. Thirty cases had positive neurological findings. Nevertheless, the many incompletely reported cases prevent conclusive generalization and demonstrate the need for well-documented studies correlating clinical, familial, and biochemical indices.

The relationship between the self-perceived cognitive disorders (SPCD) assessed using the Frankfurt Complaint Questionnaire (FCQ) and 21 definitions of schizophrenia was studied in a sample of 118 consecutively admitted patients. The FCQ total score was significantly associated (p < 0.05) with the presence of Schneider's, Yusin's and Present State Examination criteria of schizophrenia. A significant association, in this case negative, was also found between the FCQ total score and the presence of the DSM-III-R criteria of schizophrenia. The results suggest that the SPCDs are more associated with Schneider-related criteria than with chronic or deficit models of schizophrenia. It was also found that the female sex as well as the presence of insight were significantly associated with a greater number of SPCDs.

A retrospective diagnosis was obtained from a sample of 300 patients discharged from the Psychiatric Hospital of Maracaibo (Venezuela), with the clinical diagnosis of schizophrenia. These medical records were evaluated under DSM-III criteria, by two psychiatrists using structured formats. We found that 46.3% of the patients met the criteria corresponding to the schizophrenic disorder; from the remaining 53.6%, 19.6% did not have enough information to be included in this category, and 34.6% was classified under other psychiatric disorders. Of the patients with schizophrenic disorders, 61.2% were male, single, and Venezuelan citizens; 84.9% began their clinical manifestations during the second or third decade of their lives; 89.9% received education. The predominant symptomatology was impairment in social relations (93.5%), deterioration in hygiene and self- care (92.5%), impairment in functioning (87.1%), illogical thinking (86.3%), with predominant persecutory delusions, auditory hallucinations, dialogue hallucinations (84.6%), grandiose delusions (48.2%), and personal experiences of corporeal changes (45.3%). Affective symptomatology were present in all patients and the predominant subtype was the paranoid, that was observed in 80.6% of the cases. Positive signs of this disease in family history were present in 41 percent of the cases. Our findings confirm the necessity to unify criteria concerning the diagnosis of mental disorders, as it became evident that the variability in diagnosis, makes more difficult the psychiatric research in our country.

Five cases with eating disorders (one case with anorexia nervosa alone, 4 cases with anorexia nervosa and bulimia nervosa) complicated with schizophrenia and 3 cases of bulimia nervosa complicated with schizophrenia were reported. The eating disorders and schizophrenia were diagnosed according to the diagnostic criteria of DSM-III-R. As to the type of schizophrenia, 4 patients were of an undifferentiated type and 4 cases were of a disorganized type. Regarding the prepsychotic personality, 6 of the 8 cases showed schizothyme personality traits. All the patients showed depressive symptoms which are relatively common in eating disorders. In all the patients, significant social or school life difficulties persisted and a resumption of premorbid functioning was not seen. The possibility of an affinity between anorexia nervosa and schizophrenia was discussed.

One hundred American Indian patients with a Psychoactive Substance Use Disorder (PSUD) were studied with special reference to associated psychiatric disorders. This clinical sample was divided into three groups: PSUD only, PSUD plus an Organic Mental Disorder (OMD), and PSUD plus any other psychiatric disorder. OMD diagnoses included primarily Delirium Tremens and Alcoholic Hallucinosis; cases of Alcohol Amnestic Disorder, Alcohol Dementia, and trauma-induced OMD were also encountered. Other psychiatric disorders included primarily Major Depression and Anxiety Disorder, with smaller numbers of Schizophrenia, Conduct, Sexual, and other Disorders. Demographic and clinical characteristics were compared among these three groups. Those with PSUD+OMD tended to be older, male, and have more DSM-III Axis 3 disorders (American Psychiatric Association 1980) as compared to other patients; those with PSUD+other diagnoses tended to be single and younger. Education and occupational status were not related to the three diagnostic groups. The data were also subjected to MANOVA analysis. Even when corrected for sex, types of substance being abused, Axis 3 health status, and other factors, the three diagnostic groups still bore a significant relationship to age. Those with PSUD+Other psychiatric diagnoses besides OMD tended to be youngest. Those with PSUD-only were intermediate by age, while those with PSUD+OMD tended to be the oldest.

In Dutch samples of treated heroin addicts, high prevalences of a heterogeneous psychiatric co-morbidity can be found with regard to Diagnostic and Statistical Manual (third edition) (DSM-III) classifications, Zung Depression Inventory, and sum scores of a 90-item Symptom Checklist (SCL-90). A high-threshold (N = 87) and a low-threshold (N = 116) program are compared with regard to psychopathology and severity of psychopathology. A consecutive admissions design was used. More than 50% of the respondents suffered from a lifetime DSM-III Axis I disorder (70% with antisocial personality disorder included), and 40% were still suffering from one of the disorders in the year preceding the interview. Schizophrenia was diagnosed five times as much as in normal population samples (5%). The most frequently diagnosed disorders were recurrent major depression, phobic disorders, alcohol abuse and dependence, dysthymic disorder, and antisocial personality disorder. The prevalences of DSM-III disorders, the total number of symptoms, and the score on the Zung Depression Inventory and 90-item Symptom Checklist were all significantly higher in treatment-seeking drug addicts entering the high-threshold program. Within each program, three clinically meaningful subgroups can be distinguished: one group with DSM-III Axis I lifetime or current psychopathology and/or antisocial personality disorder, one with antisocial personality disorder only, and one with neither DSM-III psychopathology nor antisocial personality disorder. Possibly, self-selection results in patients with more serious conditions entering more treatment-oriented facilities. Odds ratios show that schizophrenia and mood disorders and especially associated on a lifetime and current basis.

The relationship of age and of level of adaptive functioning to comorbidity of mental disorders among alcoholics was studied in a survey of all alcoholics seeking outpatient mental health treatment in the Veterans Affairs mental health care system during a one-month period in 1986 (N = 22,463). More than half of the alcoholic outpatients had one or more comorbid psychiatric diagnoses. Rates for comorbid substance abuse disorders, posttraumatic stress disorder, schizophrenia, and personality disorders peaked in younger alcoholics and then decreased with age. Age-related increases were observed for major depression, anxiety disorders, and organic brain syndrome or dementia. DSM-III axis V ratings of poor to grossly impaired functioning were consistent across age groups. More than half of alcoholics with a comorbid psychiatric disorder were rated as severely impaired, compared with less than a third of those with no comorbid mental disorder.

Late auditory evoked potentials (AEPs) were recorded by the "odd-ball" method in 20 schizophrenic patients according to DSM III R diagnosis criteria compared with 30 control subjects matched for sex and age. Patients were on antipsychotic medications; mean duration of illness was 3, 55 years. We have also proceeded to a clinical quantitative assessment of negative and positive symptoms of schizophrenia with Andreasen's rating scales. In the group of patients, we have observed a significant lengthening of the latency of N 1, N 2, P 3, N 3 and a decreased amplitude of N 1 and P 3. These results are in favour of an impairment of cerebral information processing probably localized in the subcortical level. Statistically significant correlations have been noticed between the anomalies of the last stages of information processing (P 3, N 3) and negative symptoms, more particularly affective flattening and attentional impairment. The disturbances of the first stages of information processing (P 2) and of automatic information processing (N 2) were related to positive symptoms, hallucinations and delusions especially. The anomalies of N 2 were also related to the sum of the global scores: an attentional impairment could be a main factor in the determinism of schizophrenia.
