Patients with major depression admitted to hospital with acute stroke (n = 44), acute myocardial infarction (n = 25), or acute spinal cord injury (n = 12) were examined for differences in their phenomenological presentation of major depression. Depressed stroke patients were found to have significantly higher scores on the syndrome clusters for generalized anxiety and ideas of reference than depressed cardiac or spinal cord injury patients. In addition, significantly more stroke patients met diagnostic criteria for generalized anxiety disorder compared with the other two groups. Although spinal cord injury patients were younger, more likely to be treated with benzodiazepines, and less likely to be treated with beta-blockers, none of these factors distinguished stroke patients with anxious depression from stroke patients with depression only. These findings are consistent with the hypothesis that the etiology of depression following stroke may be different from that associated with myocardial infarction or spinal cord injury.

Lack of effect of naloxone on prolactin and seizures in electroconvulsive therapy.

Both opiate agonist and antagonist injection have been reported to modulate prolactin secretion, alter brain excitability and produce seizures, and modify the postictal state. We studied the effects of administration of high-dose naloxone, an opiate antagonist, on postictal prolactin levels, seizure duration, and postictal behavior, using patients undergoing electroconvulsive therapy (ECT) as a seizure model. Seven patients had 8 mg naloxone injected prior to one ECT treatment and saline injected prior to another treatment, with the order of injection randomized. Before ECT and 15 min after ECT, prolactin levels were drawn, and no blunting of the expected postictal prolactin elevation by naloxone injection was observed. We found no evidence that endogenous opiates trigger prolactin secretion during seizures. Seizure duration was also similar in saline and naloxone groups, and naloxone did not reverse postictal depression, as has been reported in an animal model.

Post-stroke depressive disorders: a follow-up study of 103 patients.

One hundred three patients attending a stroke clinic were evaluated for post-stroke depressive disorders using repeated quantitative assessment of psychopathology during a 12 month period. Almost one-third of these patients were depressed at the time of the initial assessment and two-thirds of these depressed patients who were re-evaluated remained depressed for 7 to 8 months. The prevalence and severity of depressive disorders was significantly elevated in those patients who were between 6 months and 2 years post-stroke. Demographic variables however did not distinguish depressed and non-depressed patients, nor did type of neurological symptoms, degree of impairment in activities of daily living or global cognitive impairment. However, patients with left hemisphere brain injury were significantly more depressed than patients with right hemisphere or brain stem infarctions. Based on this work and previous studies, we have suggested a profile for patients who are at high risk for developing post stroke depressive disorders: patients with left hemisphere frontal lobe infarctions who are within 2 years of the stroke. In spite of the fact that these depressions were clinically significant, none of the patients were presently receiving treatment. Effective treatment methods for these patients need to be developed.

A two-year longitudinal study of post-stroke mood disorders: findings during the initial evaluation.

A consecutive series of 103 stroke patients capable of undergoing a psychiatric interview were evaluated for mood disorders. Nearly 50% of patients studied in the acute stroke period had clinically significant depressions and one fourth had symptom clusters found in major depressive disorders. We confirmed our previous findings that lesion location is most important in determining frequency and severity of depression. In addition, we have identified other variables including functional physical impairment, intellectual impairment, quality of social support, and age which contribute to or modify depression. Post-stroke depressive disorders are multifactorial in their determination and expression and include both neurophysiological-neurochemical mechanisms and psychological factors in their etiology.

A two-year longitudinal study of post-stroke mood disorders: dynamic changes in associated variables over the first six months of follow-up.

We are prospectively studying a group of 103 stroke patients over the first 2 years after infarction to determine the variables which are associated with the development of depression. At both 3 and 6 months post-stroke, patients with left hemisphere infarcts showed a strong relationship between severity of depression and distance of the lesion on CT scan from the frontal pole. The strength of this association was unchanged from the immediate post-infarction period. In contrast, the correlation between degree of functional physical impairment and severity of depression steadily increased over the 6 month follow-up. The correlation between severity of depression and Mini-Mental score or between depression and social functioning score dropped between in-hospital and 3 months but then increased significantly between 3 and 6 months post-stroke. Age did not correlate with depression beyond the acute post-stroke period. Whether the increasing strength of the relationships between impairment and depression over the first 6 months post-stroke indicates that continued depression led to delayed recovery or whether continued severe impairments led to depression is not known, however, this issue will be addressed in further data evaluation from this prospective study.

The pilot Stroke Data Bank: definition, design, and data.

Four university centers collaborated to contribute 1158 patients with acute episodes of cerebrovascular disease to the pilot Stroke Data Bank, initiated by NINCDS in 1978. During the pilot project a standard set of data collection forms were developed and used at each of the collaborating centers. Data on clinical course, laboratory findings, therapy and outcome were gathered prospectively throughout the patient's hospitalization and at specified follow-up intervals. Using operational definitions of stroke sub-types, consecutive cases were systematically allocated to specific categories of brain and vascular pathology. The definitions were based on clinical criteria as well as on laboratory data, including computerized tomography (CT), and angiography findings. This paper describes the pilot Stroke Data Bank and presents the distribution of cases by diagnostic and demographic categories. It represents one of the largest series of prospectively collected stroke cases studied by CT (90% of the cases) and angiography (42%). Based upon the methods and processes of this pilot study, a main phase of the Stroke Data Bank has been established to address a number of questions pertaining to stroke classification, evolution, diagnosis, and prognosis.

Screening for depression in stroke patients: the reliability and validity of the Center for Epidemiologic Studies Depression Scale.

This study examined the inter-observer reliability and validity of the Center for Epidemiologic Studies Depression Scale (CES-D) as a measure of depressive symptomatology in stroke patients, and its utility as a screening tool for depression in this population. The CES-D Scale is a brief questionnaire originally designed for use in community surveys. Twenty-seven non-aphasic patients enrolled in the Stroke Data Bank at the University of Maryland were interviewed by a research nurse using the CES-D. On the same day, each patient was independently evaluated by a research assistant using a psychiatric battery for depression and measures of cognitive, physical, and social functioning. Forty-one percent (11/27) of the patients were depressed according to clinical criteria for major or minor depression. With a cutpoint corresponding to the upper (most severe) 20% in community surveys, the CES-D Scale picked up 73% (8/11) of the depressed patients. In this sample no nondepressed patient scored over 16 on the CES-D (no false positives). The CES-D Scale scores correlated significantly with the other depression measures (r = .57 to r = .82, p less than .002) and did not correlate with the measures of cognitive, physical, or social functioning. Based on 24 patients who received a CES-D Scale score from both the nurse and the research assistant, inter-rater reliability was high (r = .76, p less than .001). Thus, the CES-D was found to be reliable and valid as a screening tool for assessing depression in stroke patients.

Two-year longitudinal study of post-stroke mood disorders: dynamic changes in correlates of depression at one and two years.

As part of a prospective study of 103 stroke patients, we have analyzed the relation between depression and associated variables at 3 months, 6 months, 1 year, and 2 years after stroke. At all intervals up to and including 1 year poststroke, patients with left hemisphere strokes showed a strong relation between severity of depression and distance of the lesion on computed tomography scan from the frontal pole. At 2 years poststroke, this relation was no longer significant. The correlation between depression and impairment in activities of daily living peaked at 6 months and thereafter fell but remained significant at 1 and 2 years poststroke. The correlation between depression and cognitive impairment and between depression and social functioning fluctuated--with most correlations at 1 and 2 years follow-up nonsignificant. Although the conclusions that can be drawn from this study are limited by the fact that less than half of the original patients were followed up at each time, these declining correlations between depression and associated variables at 1 and 2 years follow-up may reflect the natural course of major depression which spontaneously remits between 1 and 2 years after stroke. The persisting significant association of impairment in activities of daily living with depression may reflect the effect of severe depression in sustaining and possibly retarding recovery from physical impairment.

Two-year longitudinal study of poststroke mood disorders: diagnosis and outcome at one and two years.

As part of a prospective study of mood disorders in stroke patients, interviews were obtained from 37 patients at 1 year and 48 patients at 2 years follow-up. In-hospital evaluations for these 65 follow-up patients found that 9 patients (14%) had symptom clusters of major depression, 12 patients (18%) had symptom clusters of dysthymic or minor depression, and 44 patients (68%) did not meet the DSM III diagnostic criteria for depression. Although overall prevalence of depression did not change significantly over time, the prognosis for individual patients, depending on diagnostic group, was different. All of the follow-up patients with major depression in-hospital were improved by 2 years, with a significant reduction in their mean depression scores and improvement in their activities of daily living, whereas only 30% of follow-up patients with dysthymic depression improved by this time. There was no significant improvement in their mean depression scores or mean activities of daily living score. Of the patients followed up who were not depressed in-hospital, 34% had developed major or minor depression by 2 years, and their mean depression scores were significantly increased. These data suggest that the prevalence of depression among the follow-up patients remains high (between 30 and 40%) for the first 2 years after stroke, but that untreated poststroke major depression has a natural course of about 1-2 years, with associated improvement in activity of daily living scores, whereas the prognosis for poststroke dysthymic depression is frequently unfavorable and often persists for greater than 2 years.
