The family history of major psychiatric disorders was examined among relatives of 193 in-patients fulfilling the Research Diagnostic Criteria (RDC) for Schizophrenia, Unspecified Functional Psychoses, Schizoaffective Disorder, Manic Disorder or Major Depressive Disorder. The morbid risk (MR) for schizophrenia was greater among the relatives of probands with non-affective psychoses whereas the MR for mania was greater among the relatives of probands with affective bipolar disorder. When major psychiatric syndromes were examined, only manic syndrome showed familial aggregation.

Ten patients suffering from chronic psychiatric disorder with violence were admitted for stereotactic multitarget limbic leucotomy. Eight of them were schizophrenia, one was paranoid, and one was mania. In operation, thermococagulative lesions were made bilaterally in the amygdala, the anterior cingulate region and the innominate region. The criteria of the patients selected for the operation, the operative procedure and evaluation of the results are introduced. Five patients achieved significant improvement and three patients showed some improvement after operation. The complications included, temporary mild paraplegia (in four cases) and sphincter disturbances (in five cases) in the first two weeks postoperation. The choice of targets and possible causes of complications are discussed.

After a statement of the works of P. Janet, in a precedent article, the authors study the lived time in Minkowski. They expose then the notions of syntony and schizoidy inherited by Minkowski from Bleuler and the diagnosis by penetration. The notion of lived time is at last studied in schizophrenia, then in mania where there is a subduction of lived time, it is the contrary in melancholia where the lived time is slower and some times stopped.

The classification of psychoactive drugs into minor tranquilizers (i.e. antianxiety drugs) and major tranquilizers (i.e. antidepressants, antimaniacs and antipsychotics) is based on clinical symptom rating scales. The group of symptoms in these scales of anxiety, depression, mania and schizophrenia has a shared phenomenology in the sense that the symptoms can be ordered from less to more severe. The inter-observer agreement when using these scales is adequate as agreement is of 80% or higher. By use of rating scales it has been found in controlled clinical trials that minor psychiatric disorders such as anxiety states without depression have a good outcome of placebo in 60 to 65%. In depressive disorders placebo has a good outcome in 20-45%, but in the elderly depressed patient the placebo effect is poorest (25%). Antidepressants have a good outcome in 60-75%, but in the elderly depressed patients only in 50%. In other words the drug-placebo difference is around 25%. In the major psychiatric disorders such as mania and schizophrenia the drug-placebo difference is around 50%. The use of clinical symptom scales in evaluating side-effects of psychoactive drugs is increasing. However, also non-clinical or laboratory tests have an important role in measuring side-effects, especially in motor skills related to car driving. The use of mentally healthy volunteers in measuring side-effects of major tranquilizers seems inadequate. As yet no biological methods to measure clinical effects of the tranquilizers have been developed for practical use.

The therapeutic effects of carbamazepine (CBZ) were evaluated in 103 patients with affective disorders, 54 with schizophrenic disorders, and 26 with schizoaffective disorders by a multi-institutional open study. The rate of marked and moderate improvement was 72.8% in affective disorders, 54.6% in schizophrenic disorders, and 61.5% in schizoaffective disorders. Symptom items of the Clinical Psychopharmacology Research Group rating scale for mania showed significant improvement in the patients with affective disorders as well as in those of the other two groups. In the Brief Psychiatric Rating Scale as applied to patients with schizophrenic or schizoaffective disorders, symptom items related to affect and emotion showed significant improvement. The antimanic efficacy of CBZ was also noted in many poor responders to lithium. Side-effects were observed in 82 patients (44.8%), and abnormal laboratory findings in 37 patients (44.8%), and abnormal laboratory findings in 37 patients. The present study seems to confirm the usefulness of CBZ for the treatment of affective disorders and in some cases, of schizophrenic and schizoaffective disorders.

One hundred forty-eight psychiatric inpatients, 12 outpatients, and 17 normal controls were given the 1.0-mg overnight Dexamethasone Suppression Test (DST), with salivary cortisol concentrations being measured as the dependent variable. Based on the Structured Clinical Interview for DSM-III, the patients were diagnosed as having major depression with melancholia (n = 21), nonmelancholic major depression (n = 50), mania (n = 15), schizophrenia (n = 32), dementia (n = 6), substance dependence/abuse n = 18), and miscellaneous (n = 18). Neither the melancholic major depressives nor the entire group of major depressives had significantly higher salivary cortisol pre- or postdexamethasone as compared with all the other patients combined, nor did the melancholic patients have significantly higher cortisol than the nonmelancholic depressives. The inpatients as a group had significantly higher pre- and postdexamethasone cortisol values than the normal controls; cortisol values for the outpatients were intermediate between these two groups. Illness severity (in the depressives), length of time in hospital before the DST, and medication regimen were all unrelated to DST outcome. Thus, in this study, the salivary cortisol DST showed little clinical utility in discriminating major depressives with and without melancholia from other patients with a broad range of psychiatric diagnoses. The test did distinguish between hospitalized psychiatric patients and normal control subjects and between depressed inpatients and depressed outpatients, indicating that hospitalization-related variables contributed to DST outcome.

Of 301 first-time admitted patients with delusional psychoses, 50 met DSM-III criteria for major depressive disorder (MDD), 33 schizoaffective disorder, depressive type (SADD), and 94 schizophrenia. At personal follow-up after 3-39 (mean 22) years, the SADD group was recorded in between on course and outcome variables, but closer to MDD. The findings in MDD and SADD were respectively: remission 66% vs. 42%, personality disorders 14% vs. 12%, anxiety disorder or alcohol abuse 2% vs. 6%, psychosis 18% vs. 36% (with bipolar development in 2% vs. 6%, paranoid disorder 2% vs. 3%, schizophrenia 4% vs. 3%). Chronic psychosis was recorded in 10% vs. 27%. No significant outcome difference was found between early onset MDD and SADD cases and those who fell ill at a higher age. The assumption that antidepressants may induce mania could not be confirmed. Normal premorbid personality seemed to predict a favourable course.

The existence of seasonal variations in the dexamethasone suppression test (D.S.T.) has been remarked. In a sample of 345 patients with affective symptomatology and various psychiatric diagnostics, patient with major depression have higher non suppression levels in spring and winter; a similar but stronger seasonal variations is observed in patients with melancholic and patients with psychotic syndrome showed a similar tendency. In patients with diagnostics different from depression (dementia, schizophrenia, mania, anxiety disorders), the non suppression level is higher in winter. Some similarities with the contributions of other authors are observed but in general disagreements are more frequent, which suggests us the influence of latitude and geo-climatic changes, since the seasonal variability can not be explained by means of seasonal changes in demographic or clinical variables, as diagnostic or psychiatric syndrome.

A recent review of the literature on Post-Traumatic Stress Disorder (PTSD) and the MMPI has shown that all previously published studies have been limited to clinical groups whose trauma occurred in Vietnam combat. The purpose of this study was to test hypotheses that predict higher MMPI and PTSD scale scores among combat veterans who differ in degrees of noncombat traumas. Results support predictions. Those who reported more noncombat traumas attain significantly higher MMPI scores for scales F, Hypochondriasis, Hysteria, Psychopathic Deviate, Psychasthenia, Schizophrenia, Mania, Social Introversion, and an MMPI PTSD score (Keane, Malloy, & Fairbank, 1984). Moreover, noncombat effects are manifested differentially: Combat veterans with higher noncombat trauma evidence greater social withdrawal, whereas noncombat veterans who report higher noncombat trauma are characterized by higher anxiety. MMPI elevations were progressively higher as groups increased in degrees of combat and noncombat trauma: noncombat and low combat trauma veterans were the better adjusted, and combat veterans with higher noncombat trauma were the worst adjusted. Results provide descriptive validity for PTSD as a construct and underscore the importance of assessing frequency and intensity, as well as types of traumas and stresses, in the background histories of substance abusers and other clinical groups as well.

This study asked, "What are the psychological characteristics of Vietnam combat veterans who claim Agent Orange exposure when compared with combat-experienced cohorts who do not report such contamination?" The question was researched among 153 heroin addicts, polydrug abusers, and chronic alcoholics who were seeking treatment: 58 reported moderate to high defoliant exposure while in combat; 95 reported minimal to no exposure while in Vietnam. The null hypothesis was accepted for measures of childhood and present family social climate, premilitary backgrounds, reasons for seeking treatment, patterns and types of illicit drug and alcohol use, interpersonal problems, intellectual functioning, and short-term memory. The null hypothesis was rejected for personality differences, however, those who self-reported high Agent Orange exposure scored significantly higher on MMPI scales F, Hypochondriasis, Depression, Paranoia, Psychasthenia, Schizophrenia, Mania, and Social interoversion. The results suggest that clinicians carefully assess attributional processing of those who report traumatic experience.
