Suicide has been associated traditionally with major depression, alcoholism, and schizophrenia and in the past several years with alcoholism and comorbid depression. More recently, however, panic disorder has been linked with suicide attempts, and the importance of severe anxiety symptoms (panic attacks, psychic anxiety, and agitation) as possible predictors of suicide risk in patients with major affective disorder has been studied. The author discusses data sets from three such studies: (1) the Clinical Studies of the National Institute of Mental Health Collaborative Program on the Psychobiology of Depression, (2) a study on 17-hydroxycorticosteroid concentrations in inpatients with major affective disorder, and (3) a study on inpatient suicides. The author concludes by suggesting that anxiety, which is readily treatable, may in fact be one of the most clinically important symptoms in depressive disorders.

Exploratory eye movements in schizophrenic and nonschizophrenic subjects were examined with an eye mark recorder while the subjects viewed geometric figures. Elementary components of eye movements and the responsive search score (RSS), a function of the number of sections on which the subjects fixated, were measured by means of an eye movement analyzer and slow motion replay. The schizophrenic group and the depressed patient group had fewer eye fixations than the normal control group and the obsessive-compulsive disorder group. The schizophrenic group had a lower RSS average than patients with depression, patients with obsessive-compulsive disorders, or subjects in the normal control group. These results in conjunction with those of our previous studies suggest that a low RSS is specific to schizophrenia. We examined the relationship between these eye movements and neuropsychological tests and also investigated the relation between the eye movements and clinical symptoms by means of the Brief Psychiatric Rating Scale, Schedule for Affective Disorders and Schizophrenia, and the Scale for the Assessment of Negative Symptoms. The RSS correlated positively with the performance IQ and Wechsler's Maze test, but not with the Wisconsin Card Sorting Test or the verbal IQ result. The RSS also correlated negatively with negative symptoms. These results suggest that the RSS has two characteristic features: it is strongly associated with the interpersonal response and it may be connected with visuospatial and visuomotor functions including attention.

Both psychiatric patients and their relatives benefit from learning about mental illness and how to cope with it, but the specific interests of these consumers remain unclear. To determine specific educational needs and to compare the needs of different consumers, a questionnaire survey was conducted with a sample of patients with schizophrenia and affective disorder and their relatives. Both patients and relatives reported strong interest in learning more about psychiatric illness and strategies for coping with common problems, but patients with schizophrenia were less interested than patients with affective disorder and both sets of relatives. Discriminant analyses revealed that needs differed as a function of patient diagnosis, patient/relative status, and relatives' membership of a self-help and advocacy organisation. Consumers of mental health services are capable of specifying their own educational needs, and educational programmes should be tailored to meet these.

There is little information about hypothalamic-pituitary-adrenocortical (HPA) axis function in mania, particularly in mixed states. We therefore investigated HPA function and its relationship to clinical state in 19 hospitalized manic patients meeting Schedule for Affective Disorders and Schizophrenia - Research Diagnostic Criteria for acute manic episodes, compared patients with and without a mixed presentation, and examined correlations between HPA activity and behavior. Data were available from 13-16 patients. Behavioral and biochemical analyses were conducted during a 15-d placebo period. Patients with mania had elevated cerebrospinal fluid (CSF) and urinary free cortisol excretion compared with healthy subjects, and did not differ from depressed patients in any cortisol measures. Mixed manics had significantly higher morning plasma cortisol, postdexamethasone plasma cortisol and CSF cortisol than pure manics. Five of 7 mixed manics and 3 of 9 pure manics were dexamethasone suppression test (DST) nonsuppressors. Afternoon plasma cortisol and CSF cortisol correlated significantly with depressed mood; urinary free cortisol correlated with anxiety. None of the cortisol measures correlated with mania or agitation scores. These data suggest that increased cortisol secretion is a characteristic of the depressed state in mixed manics, although pure manics may also have increased DST nonsuppression.

A two-stage epidemiologic study conducted between 1986 and 1988 in the southeastern United States investigated the frequency of major depressive disorder and dysthymia in 12-14 year olds. In stage one, the Center for Epidemiologic Studies Depression Scale, a life event schedule, and a family cohesion scale were administered to a community sample of 3,283 adolescents. In stage two, 488 mother-child pairs were interviewed utilizing the Schedule for Schizophrenia and Affective Disorders in School Age Children. Although mean Center for Epidemiologic Studies Depression Scale scores were significantly higher in females (25.60) than in males (19.50), prevalence estimates based on a summary of mother and child symptom reports for Diagnostic and Statistical Manual of Mental Disorders, Third Edition, major depressive disorder were similar: 9.04% in males and 8.90% in females. The prevalences of dysthymia were 7.98% in males and 5.00% in females. Previous investigations have reported lower rates and a female preponderance of major depression. Disagreement between mothers and children regarding the presence of symptoms may explain this contradiction. Significant odds ratios were found between major depression and not living with both natural parents (odds ratio (OR) = 3.89), undesirable life events (OR = 1.09), and perceived family cohesion (OR = 0.96). Not living with both natural parents (OR = 14.67) and socioeconomic status (OR = 0.44) were significant correlates of dysthymia.

Changes in brain structure have been demonstrated in elderly patients suffering affective disorder. Enlarged ventricles are associated with cognitive impairment and higher mortality. Depressed subjects also may show a greater degree of cortical atrophy and subcortical white matter, and basal ganglia lesions seem to be commoner than in age-matched controls. The abnormalities demonstrated are not as severe as those found in degenerative dementias such as Alzheimer's disease, and at present there is no evidence to suggest they are progressive. There is a convincing association with vascular disease, although further neuropathologic correlates are needed. Functional imaging methods are just beginning to be applied to elderly populations and, in affective disorder, findings are similar to those in younger patient groups. The results from different groups vary due to technologic differences and the clinical heterogeneity of the patients studied. Depression, however, may be accompanied by decreased and mania by increased cerebral blood flow or metabolism. Evidence also appears to be mounting of a state-dependent frontostriatal dysfunction in depression. Challenges for the future include replicating such results using larger diagnostically homogeneous patient groups and differentiating the findings from those in other disorders such as schizophrenia and basal ganglia disorders.

Discriminant functions of the MMPI and the MCMI-II were compared in a sample of 166 hospitalized psychiatric patients with discharge diagnoses of affective disorder (63), schizophrenia (26), substance abuse (35), and other disorders (42). Of special interest was the comparative diagnostic utility of the two instruments in regards to DSM-III-R Axis I diagnoses. Both tests performed reasonably well in the discriminant function analyses; however, the MCMI-II achieved a somewhat superior overall hit rate with this sample of inpatients (79% to 68%). This difference was tied to greater accuracy of the MCMI-II for identifying the affective disorders group.

With the last two decades, the importance of genetic factors in the aetiology of major mental illness has been firmly re-established and psychiatric research has now firmly embraced the era of molecular genetics. Despite a number of false starts in the study of schizophrenia and affective disorder, there have been successes in unmasking some of the aetiological secrets of Alzheimer's disease. We will give an overview of the rationale behind these studies and the major findings to date.

The present study examined the association between electrodermal activity (EDA) and season of birth in a sample of first-episode patients with schizophrenia, schizophreniform disorder, and affective disorder with psychotic features, and in a normal control group. Patients with schizophrenia who were born during the season of excess risk (January-April) were less responsive than those born during other times of the year. They had lower skin-conductance levels and fewer skin-conductance responses. No such effects were found in patients with schizophreniform or affective disorder, or in the normal subjects. When compared with the control group, winter-born schizophrenics showed significantly more evidence of hyporesponsivity. In contrast, nonwinter-born patients did not differ from normal subjects in skin-conductance level or number of skin-conductance responses. Schizophreniform patients born during the other seasons of the year were more likely to be hyporesponsive. The above results provide supporting evidence for the validity of the season of birth phenomenon. We hypothesize that a viral infection, or some other perinatal complication associated with winter and early spring births, leads to temporal lobe damage and consequent dysregulation of electrodermal activity in patients with schizophrenia.

Platelet [3H]imipramine binding was measured in 40 migrainous (7 classical and 33 common) and 17 tension headache patients and in 28 normal controls. A significant reduction in Bmax was found in migraine compared with controls (p less than 0.05) but not in tension headache. In migraine, there was no significant relationship between Bmax and depression or anxiety score on the self-rating Hospital Anxiety and Depression (HAD) Scale, suggesting that the reduction in Bmax is a concomitant of migraine itself rather than a manifestation of associated depression. Preliminary evaluation using the Schedule of Affective Disorders and Schizophrenia-Lifetime Version (SADS-L) tended to confirm this conclusion.
