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.

A clinical picture of mania can have many causes, including amphetamine or cocaine use, acute schizophrenia, manic-depressive illness, and viral encephalitis. Accurate and complete history--of both the present episode and past experiences--is most valuable in the differentiation, along with mental status examination, physical examination, and selected laboratory tests. It is advisable to withhold drug therapy, if possible, until the initial evaluation is completed, for it may obscure the diagnosis.

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.

Eighty-five patients with both schizophrenic and affective features at the time of admission to the University of Iowa Psychiatric Hospital between 1934 and 1944 were selected for a 30- to 40-year outcome study. Comparison groups were 200 schizophrenic and 325 affective disorder patients, selected by the Feighner et at criteria, and 160 psychiatric symptom-free surgical patients. We assessed marital, residential, occupational, and psychiatric status to evaluate the outcome of these patients at the time of field follow-up. We used multivariate analysis of covariance to analyze the data by taking admission marital and occupational status into consideration. Patients with schizoaffective disorders had a significantly better outcome than those with schizophrenia, but a significantly poorer outcome than those with affective disorders and surgical conditions. Schizoaffective disorder fell somewhere in between the schizophrenia and mania group. Before final conclusions could be made about the nature of schizoaffective disorders, more research should be done.

This investigation evaluates the frequency of various subtypes of thought, language, and communication disorders in 113 patients with diagnoses of mania, depression, and schizophrenia. It indicates that some types of thought disorder considered important occur so infrequently as to be of little diagnostic value, such as neologisms or blocking. The traditional concept of thought disorder, which emphasizes associative loosening, is also of little value, since associative loosening occurs frequently in mania as well as in schizophrenia. This investigation demonstrates that associative loosening can no longer be considered pathognomonic of schizophrenia. On the other hand, an approach that defines various subtypes of thought disorder and uses a concept of negative-vs-positive thought disorder does often permit a distinction between mania and schizophrenia. It is recommended that the practice of referring globally to "thought disorder," as if it were homogeneous, be avoided in the future and instead that the specific subtypes occurring in particular patients be noted in both clinical practice and research.

Recently, provisional research criteria for "schizo-affective" and related psychoses were published by the St. Louis Group. These rigorous criteria were modified and expanded for purposes of the present study in order to analyze the case records of 83 first admissions of Schneider-positive schizophrenics, that is, those with first rank symptoms, hospitalized in a strongly Schneider-oriented German University Clinic during the period 1962-1971. Research diagnosable "schizo-affective" disorder was thus found in 27.7% (23 cases) of these patients; 12 of the 23 satisfied "full" affective research criteria for depression or mania, whereas 11 fulfilled "adjusted" affective criteria geared to cover more "labile" mixed mood states. Moreover, 48.2% (40 cases) and 25.3% (21 cases) of the sample were research-positive for "schizophreniform" illness and "atypical schizophrenia" respectively. Findings such as these suggest that "first rank" schizophrenia, as routinely diagnosed in Germany, may not be all that homogeneous a clinical entity.

After exposure to a low and high dose dexamethasone regime, 11 of 34 acute psychiatric inpatients demonstrated abnormal dexamethasone suppression characterized by morning and/or mid-afternoon escape from suppression. This abnormality of suppression was found in primary depression, in mania, and in acute schizophrenia. In primary depression, the presence of abnormal dexamethasone suppression failed to discriminate "endogenous" depressed from "other depressed" subjects. Because nonsuppression to a high dose of dexamethasone is also found in patients with ectopic ACTH secretion and in patients with autonomous adrenal tumors, caution is necessary in the interpretation of nonsuppression which persists after recovery from psychiatric illness. As patients with Cushing's syndrome of uncertain etiology may be referred to a psychiatrist for a diagnostic evaluation, the psychological correlates of abnormal dexamethasone suppression need to be established with greater certainty.

The uptake of tryptophan and tyrosine by the brain has been studied in 6 manic-depressive patients and in 8 schizophrenics. In an attempt to saturate the blood-brain transport mechanisms, this uptake has been evaluated by measuring the arteriovenous differences (arterial plasma-internal jugular plasma) of these two amino acids before and after perfusion with L-dopa and L-5-HTP. Considering a positive difference as an uptake and a negative one as an outflow, results show (1) in melancholia an uptake of tryptophan and an outflow of tyrosine; (2) in mania an uptake of tyrosine and an outflow of tryptophan, and (3) in schizophrenia an outflow of tryptophan accompanied with either an uptake or an outflow of tyrosine. In addition, the kinetics of tryptophan binding to plasma proteins and the ratio of tryptophan/tyrosine uptake are different in manic-depressive illness and in schizophrenia. These results support the view that a disturbance in the blood-brain transport mechanisms of tryptophan and tyrosine could be involved in the physiopathology of manic-depressive illness and schizophrenia.

A questionnaire regarding medication preferences for major categories of psychiatric disorders was sent to 1,059 psychiatric drug investigators in 53 countries. 264 questionnaires were returned, of which 165 were appropriate for this survey. A total of 87 different psychotropic drugs were selected. Chlorpromazine was the medication most frequently cited in the treatment of schizophrenia. Amitriptyline and imipramine together accounted for the vast majority of medication chosen for all varieties of depression. In the treatment of mania, chlorpromazine was chosen by almost one-third of our sample, lithium by only one-fifth. Chlordiazepoxide and diazepam were equally preferred in the treatment of alcoholism. Most psychiatrists preferred not to use any psychotropic medications consistently in treating patients with organic brain syndromes. The implications of this study are discussed and compared uith similar studies in more limited geographical regions and in children.
