In a study of electrolytes in lumbar cerebrospinal fluid (csf) from psychiatric patients, the authors found a positive correlation between calcium concentration and symptom severity in hospitalized depressed patients. CSF calcium levels tended to decrease as patients improved. In four rapidly cycling patients, CSF calcium was higher during depression than during mania. Mean CSF calcium for the depressed patients as a group was not significantly different from neurological controls or other psychiatric patients. Symptom remission from acute psychosis in schizophrenic patients was accompanied by a significant increase in CSF calcium concentration. These findings are discussed in relationship to calcium-induced alterations in neuronal and physiological excitability.

The author attempted to determine whether the Minnesota Multiphasic Personality Inventory (MMPI) would be sensitive to a symptom pattern unique to lithium-responsive patients regardless of diagnosis. Statistical analyses of the MMPI scores of lithium responders, lithium nonresponders, and a group of patients receiving other psychotropic drugs revealed that the depression, psychasthenia, mania, and social introversion scale scores significantly differentiated the lithium response and lithium nonresponse groups. No strong indications of significant difference were found between the MMPI scale scores of the lithium nonresponse and psychotropic groups. The results suggest that there is a lithium-responsive syndrome that exhibits a distinctive symptom pattern regardless of its varying phenomenological features in different individuals.

Plasma and erythrocyte cations (sodium and magnesium) were studied in groups of patients with an affective disorder and in normal subjects. Baseline determinations were obtained before initiation of treatment for mania or depression. In a subgroup of patients, sequential measurements of cations were made during treatment with lithium carbonate. No differences were found in intraerythrocyte sodium or magnesium among any of the patient groups and controls. Patients with a primary affective disorder had significantly higher plasma sodium than control subjects. Neither baseline cation concentrations nor changes in cation concentration during treatment with lithium correlated with treatment response. Gender was shown to be a significant variable affecting intraerythrocyte cation concentrations.

In a study of 18 patients with manic symptomatology and 31 patients with melancholic symptomatology the Bech-Rafaelsen Mania Scale (BRMS) and the Hamilton Depression Scale (HDS) have been compared. The results showed that the inter-observer reliability of the BRMS was adequate compared with the HDS. Both scales are constructed for assessing the severity of manic or melancholic states, and no difference was found in the total BRMS or HDS score between the various diagnostic groups, when the patients were classified by an index of the course and symptomatology otive disorder, using the Multi-axial Classificetion System for Affective Disorders (MULTI-CLAD). The homogeneity of the BRMS seemed more adequate than that of the HDS, when each item was correlated to the corresponding total score. Although the homogeneity of the BRMS needs to be evaluated by other statistical models than correlation analysis, our results seem to indicate that the improvement in assessing manic-melancholic states quantitatively is a matter of redefining items or incorporating new items in the melancholic rather than the manic part of these rating scales.

The authors present a schema for conceptualizing psychiatric illness in terms of state and trait disorders. These disorders are relatively independent components, one or both of which can be present in one patient. They usually require treatment by different methods. State disorders, such as schizophrenic psychosis, mania, and depression, are time-limited and autonomous and respond better to pharmacological than psychosocial therapy. Trait disorders, such as neurotic and characterological disturbances, are long-lasting and respond better to psychosocial therapies. The authors discuss the implications of this schema for the integration of pharmacological and psychosocial treatments.

Maintenance tricyclic antidepressants induced rapid cycling between mania and depression in five female bipolar (manic-depressive) patients. Lithium carbonate did not prevent the tricyclic-induced rapid cycling, although two patients subsequently responded well to lithium carbonate alone. In these patients, the action of tricyclics can be conceptualized as accelerating rather than counteracting the natural, cyclic course of the illness in all of its phases. In this respect, tricyclics are analogous to several other drugs that are capable of modulating the frequency of oscillatory biological processes.

The author used a scale that emphasizes objective behavioral signs to evaluate affective flattening and to rate affect in 69 patients suffering from schizophrenia (N = 30), mania (N = 19), and depression (N = 20). Raters were blind to the patient's diagnosis. Interrater reliability was assessed and found to be adequate to good for most items on the scale and for a global rating. The affective flattening was found to be common, but not omnipresent, in schizophrenia; it was also common among the depressed patients. The author recommends that affective flattening be considered as an important criterion for schizophrenia and that future research explore its frequency and prognostic significance.

Salivary secretion was measured in 54 psychiatric patients comprising four diagnostic groups: schizophrenia, mania, depression and anxiety state. Detailed psychometric assessment was carried out at the time of measurement. Although salivary flow failed to show an association with either diagnostic category or mental state at the time of examination, it was positively correlated with a subjective rating of appetite. The implications of these findings are discussed.

This first part of a multiphase longitudinal study looks at life events implicated in manic depression among an American working class, bipolar sample. Three turning points are identified. a) Stressful life events occurred that resulted in loss of significant social roles. b) Attempts to regain or replace the roles or otherwise "fight back" proved ineffective. c) Retreat via depression, and rebellion via mania, ensued. These turning points were well verified for 75 per cent of the subjects prior to first onset, and for 56 per cent prior to most recent onset. Special methodological issues are raised, and the need for a biopsychosocial etiology of manic depression is suggested.

We conducted a 30- to 40-year field follow-up of 685 patients with schizophrenia, affective disorders, and nonpsychiatric conditions. Long-term outcome was analyzed in terms of the patients' marital, residential, occupational, and psychiatric status. On the whole, psychiatric patients showed a significantly poorer outcome than the surgical controls. On the basis of long-term outcome, schizophrenia, and affective disorders, selected according to the specified research criteria, were significantly different: schizophrenia definitely showed poorer outcome than affective disorders. However, no significant differences in all four outcome variables were found between mania and depression. We hope that the present data on long-term outcome of the typical cases can be used to compare outcome of other psychiatric disorders, such as undiagnosed psychoses, having mixtures of schizophrenic and affective features. In doing this, we hope to charify our understanding of undiagnosed psychoses and their relationship to schizophrenia and affective disorders.
