Diagnosis of affective disorders and schizophrenia in the U.S.: a 1984 survey of psychiatrists and graduating residents.

During a 5-month period in 1983 and 1984, the authors surveyed a random sample of U.S. psychiatrists and all psychiatric residents graduating in 1984, with response rates of 56.1% and 51.9% respectively. They report the diagnostic classifications and subtypes used by the clinicians as well as the clinical features required by the clinicians to diagnose affective disorders and schizophrenia. When diagnosing schizophrenia, the graduating residents differed from their senior colleagues by giving more importance to the course of illness, duration of symptoms, and exclusion of affective disorder. These findings are discussed in light of past surveys and the development of new diagnostic systems.

Electroconvulsive therapy in parkinsonism with affective disorder.

The authors report a patient whose Parkinson's disease and mania both responded well to electroconvulsive therapy (ECT) after failing to respond to chemotherapy. The authors review the literature and suggest that ECT is a safe and effective treatment for affective syndromes associated with Parkinsonism. The presence of dementia in these patients appears to be an indicator of poor prognosis. This paper is believed to be the first report of successful use of ECT in mania occurring together with Parkinsonism.

Consumers' views of DSM-III: attitudes and practices of U.S. psychiatrists and 1984 graduating psychiatric residents.

The authors surveyed U.S. psychiatrists and psychiatric residents graduating in 1984 about their use and views of DSM-III. Although the majority approved of DSM-III generally, 35% of the psychiatrists and 20% of the residents said they would stop using it if it were not required. Residents accepted DSM-III better than did practicing psychiatrists. Many of the respondents doubted the validity of some diagnoses and stated that many of their patients did not satisfy criteria needed for the DSM-III diagnoses in their records. Most respondents did not use all DSM-III axes and did not want new axes. The authors discuss the survey results and their implications for revision of DSM-III.

Mania with emotional blunting: affective disorder or schizophrenia?

Fourteen of 134 consecutively admitted manic patients exhibited emotional blunting in addition to the full manic syndrome. The authors compared these 14 blunted manic patients with the remaining 120 nonblunted manic patients and with 31 schizophrenic patients admitted during the same period. They found that the blunted manic patients more closely resembled schizophrenic than nonblunted manic patients on most of the demographic, clinical, and familial variables studied. Although mania with blunting may represent a variant of schizophrenia, the etiologic association between long-term neuroleptic administration and emotional blunting requires further study.

Mania secondary to left and right hemisphere damage.

The authors report on two fully right-handed men without prior psychiatric history who developed mania secondary to vascular lesions of the left and right hemispheres, respectively. One patient, whose left hemisphere lesion produced a transient posterior aphasia, is believed to be the first patient reported in the literature whose secondary mania followed damage to the hemisphere documented to be dominant for both handedness and speech. The authors conclude that it is premature to consider mania to a be syndrome of the nondominant hemisphere.

Effect of age on QT variability.

Heart rate variability is influenced significantly by age. Recent studies have shown the utility of QT variability to study temporal repolarization lability, and increased QT variability is reportedly associated with sudden death. Because beat-to-beat QT interval variability appears to closely follow heart rate variability, this study investigated the relationship between age and QT variability. We obtained QT variability measures in 34 adults (22-55 years of age) and 15 children (6-14 years of age) using a novel algorithm to compute beat-to-beat QT intervals. QT variability corrected for mean QT interval was significantly inversely correlated with age. Coherence in the band of 0 to 0.5 Hz and high-frequency coherence (0.15-0.5 Hz) were also significantly inversely correlated with age. QTvi (QT variability corrected for mean QT interval over heart rate variability corrected for mean heart rate) was not significantly related to age in supine posture during spontaneous or controlled breathing, whereas there was a modest negative relationship in standing posture. These findings suggest that coherence between QT and heart rate time series appears to be modulated by cardiac vagal activity.

Consumers' attitudes toward DSM-III and DSM-III-R: a 1989 survey of psychiatric educators, researchers, practitioners, and senior residents.

To understand how DSM-III and DSM-III-R are used and perceived by educators, researchers, practitioners, and trainees, in the spring of 1989 we surveyed all US psychiatric residency training directors (N = 197), 337 active psychiatrist researchers, a nationwide random sample of 952 practicing psychiatrists, and all PGY-3 and -4 residents. We describe the factors influencing the use of DSM-III and DSM-III-R and the perceptions of strengths and weaknesses of the DSMs from various perspectives (training, research, and practice). A modest increase in the acceptance of the DSM system was noted in comparing the results from the current survey and a similar 1984 survey about DSM-III. The implications of these findings for the development of DSM-IV are discussed.

DSM-III and DSM-III-R: what are American psychiatrists using and why?

The purpose of this study was to determine whether American psychiatrists have switched from DSM-III to DSM-III-R as their primary diagnostic reference, and to examine what factors predicted the continued use of DSM-III. In 1989, we conducted a mail survey of practicing psychiatrists (N = 454), residency program directors (N = 128), residents (N = 1,331), and researchers (N = 196) regarding their training in, use of, and opinions about DSM-III and DSM-III-R. Approximately 30% of practitioners continued to use DSM-III as their primary diagnostic reference, although this was less frequently true of researchers and residents. In none of the four groups did a majority believe that DSM-III-R was needed, despite the fact that the majority of each group indicated that it was an improvement over DSM-III. The most commonly perceived reasons for publishing DSM-III-R were that it corrected problems with DSM-III and new research indicated changes were warranted. Compared with DSM-III-R users, DSM-III users more frequently believed that the 7-year interval between the two editions was too short, that DSM-III-R was not needed, and that the revised manual was little better than the original. Thus, 2 years after the publication of DSM-III-R 90% of psychiatrists were using DSM-III-R, at least in part, although a substantial minority continued to use DSM-III as their primary diagnostic manual. Even among DSM-III-R users, many believed that the revised manual was not needed. The perceived need for DSM-III-R was associated with the reasons ascribed to its publication; therefore, acceptance of DSM-IV may be partially a function of how its development is promoted and justified. That nearly one third of a random sample of practicing psychiatrists continued to use DSM-III supports concerns that the publication of DSM manuals every 6 or 7 years will divide the psychiatric community into subgroups using different diagnostic criteria.

Psychosensory features in mood disorder: a preliminary report.

The purpose of this study was to determine the prevalence of psychosensory features in mood disorder patients, and to investigate the relationship between psychosensory features and classic psychopathology. We evaluated 50 mood disorder patients (39 bipolar, 11 schizoaffective) for the presence of psychosensory features and psychopathology. We assessed psychosensory features separately using the Profile of Psychomotor Symptoms. We obtained additional information regarding each patient's psychiatric and drug history, family history, and electroencephalogram. Seven (14.0%) experienced three or more recent psychosensory features, and 12 (24.0%) reported three or more past psychosensory features. The presence of alcohol and drug abuse, number of medications, and electroencephalographic abnormality had no effect on the prevalence of psychosensory features. Psychosensory features significantly (rs = .53, P < .001) correlated with hallucinations, but not with other psychopathology (P > NS). Psychosensory features are not uncommon in mood disorders and have a strong relationship with hallucinations. Our findings also suggest that the presence of psychosensory features in mood disorder suggests episode severity and not a specific subgroup.
