A retrospective chart review of 54 patients demonstrating depression with psychotic symptoms was accomplished with the use of Research Diagnostic Criteria (RDC) for diagnosis of psychotic major affective disorder. Patients received adequate trials of either tricyclic antidepressants alone, antipsychotics, the two in combination, or electroconvulsive therapy (ECT). Antidepressants alone were found to be ineffective or only partially effective in treating psychotic depression unless somatic or depressive declusions were the only psychotic symptoms. Antipsychotics alone were usually effective in providing at least a partial response, particularly with psychotic symptoms. Excellent responses of the depressive and psychotic elements were provided with ECT, ECT with antipsychotic medication, and the combination of antidepressant and antipsychotic medications. These latter treatments may be the most appropriate for depression with psychotic features.

It is for a good reason that the colloquium is entitled Affective disorders and not Depression: in reality there is a profound unity between elation and depression and we have to ask ourselves whether there may be inversion of mood in any case of elation and vice-versa. Mood inversion occurs in various conditions: depression sets in a previously elated person, finally overwhelmed by the consequences of his acts; or elation may occur as an over-compensation for the pain of loss. These two situations lead either to a paradoxical content of the patient's talk or to a metapsychological elaboration. Finally, the change may take place without there being a clear psychological formulation. The concomitants of these phenomena, involving the biological amines or the neurotransmitters, must be elucidated. Clinically, there are two types of problem: the problem of the premonitory signs of inversion of mood and the problem of attempting to prevent it.

Platelets were examined to enable a simultaneous investigation to be made of indolylamine and electrolyte metabolism in affective disorder. No significant differences were detected in either platelet membrane ATPase or adenyl cyclase specific activity in any of the groups of patients studied, when compared with appropriate controls. A reduced Vmax and y for the 5-hydroxy-tryptamine uptake process into platelets was observed in both unipolar and bipolar depressed groups. The Km for this process was not significantly different in any of the patients from that found in control subjects. Lithium therapy was shown not to influence significantly any of the platelet parameters examined. It is suggested that membrane enzyme changes found in some peripheral cells in patients suffering from affective disorder, i.e. reduced Na+ + K+ - ATPase activity in erythrocytes in depression, is not common to all peripheral cells and may or may not reflect central nervous system changes.

Narrow definitions of schizophrenia increase homogeneity at the expense of leaving unclassified many patients with shizophrenic symptoms. Family history and follow-up studies indicate that many such patients ought to be classified with those having affective disorders. This study determines morbid risks for affective disorder and schizophrenia in first degree relatives of patients with chart but not research diagnoses of schizophrenia. Comparisons with morbid risk figures for relatives of individuals satisfying research criteria for depression, mania or schizophrenia indicate that the 'non-Feighner schizophrenia' group is probably too heterogenous to be classified entirely as affective disorder or as schizophrenia.

In a sample of middle class individuals seeking martial and sexual counseling, 30% had diagnosable psychiatric illness, including 14% who had depressions at the time of interview. Those with psychiatric syndromes were significantly more likely to have prescribed psychoactive than those without these syndromes. Those with depression were more likely to have received diazepam and similar drugs than antidepressants. The same was true for those with other syndromes but in many of these cases, diazepam or other antianxiety agents seemed more appropriate. Thus, affective disorder might well be the psychiatric syndrome for which these drugs are most often inappropriately prescribed. Inappropriate treatment is a matter of concern in an illness which is potentially fatal.

As requirements for tryptophan for synthesis of protein and 5-hydroxytryptamine were comparable in rat brain, during depletion of tryptophan there could be competition between the two pathways for the amino acid. This implied that tryptophan should be rate-limiting for protein synthesis and this was found in the short term when concentrations of the amino acid were reduced in rats. Multicompartmental studies of tryptophan and tyrosine in controls and patients subject to unipolar depression defined two main pools of the amino acid provisionally assigned to extracellular and intracellular spaces. For tyrosine, mean values for the extracellular space were comparable to those of controls. The concentration of tyrosine was low in the intracellular space in both depressed and recovered patients, but the raised fractional clearance rates for this compartment during depression had returned to normal on remission. Plasma tryptophan concentrations were significantly reduced in depression with intermediate values after recovery. This suggested that the procedure used may have been mildly stressful and that this had evoked an idiosyncratic response to the stress in the depressed patients, which was characterized by inability to maintain concentrations of this amino acid in plasma. The findings for both amino acids may have a bearing on the aetiology of unipolar affective disorder.

Seven men and one woman with primary affective disorder, mania, were given a slow intravenous infusion of physostigmine salicylate. In six patients, mood and thought content changed from mania toward depression as evaluated by either a visual analog mood scale or the Pettersen scale. Two other patients, who were the only predominantly irritable manics in the study, demonstrated little change in their hostility, although one became somewhat depressed. These findings are consistent with earlier reports of suppression of manic symptoms after physostigmine infusion in some but not all patients with mania. The pharmacologic mechanism of physostigmine reversal of manic symptoms may be the direct result of increased cholinergic activity or a result of the effect of increased cholinergic activity on other brain neurotransmitters.

Lithium carbonate has established itself as an effective therapeutic agent in primary affective disorders. As not all the patients with primary affective disorders respond to lithium therapy, it is necessary to identify responders prior to treatment. The important indicators of favourable lithium response include a definitive diagnosis of primary affective disorder, occurrence of less than four episodes of mania and depression within one year, psychotic features during both manic as well as depressive episodes, "grandiose-elated" picture during manic episodes; a family history of bipolar illness and response of affected family members to lithium treatment. While those with more than four episodes are not likely to respond to lithium therapy, those with episodes less frequent than once a year or two may not need prophylactic lithium. Among the depressed, hypersomnic depressed patients respond to lithium combined with a monoamine oxidase inhibitor. In addition to clinical predictors of response to lithium treatment, there are a number of pharmacokinetic, neurophysiological and biochemical indices which have been employed as supplementary predictors of response to lithium therapy.

A group of 111 women physicians and 103 women PhDs, selected from the general community, were studied for the presence of psychiatric illness. Fifty-one percent of the MDs and 32% of the PhDs were diagnosed as having primary affective disorder (P less than .01). Other psychiatric disorders were found in less than 10% of each group. Depression among the psychiatrists was significantly more common (73%) than among the other physicians (46%). More than 50% of all the women reported prejudice in training or employment, and depressed subjects reported prejudice more often than well subjects. The presence of children and depression were shown to disrupt a woman's professional career. The finding of a high prevalence of affective disorder among women physicians is consistent with the reported excessive suicide risk for this group.

All the children (ages 5-15) of 14 consecutive patients admitted to hospital at the National Institute of Mental Health with a diagnosis of bipolar or unipolar affective disorder were studied. The children were seen twice, four months apart, and assessed by an interview and rating scales. The parents were also assessed. Of 14 boys, five were depressed on both interviews and three were depressed on one interview. Four of the 16 girls were depressed on both interviews and 11 were depressed on one interview. The clinical picture and the ratings showed the boys, but not the girls, to have a significant correlation for depression on both interviews. The children diagnosed as suffering from depression showed the symptoms of a primary unipolar affective disorder without other significant pathology.
