Previous studies have demonstrated that patients with major depression following stroke have a greater degree of cognitive impairment than nondepressed patients with comparable lesions. The present study examined the longitudinal course of cognitive impairment related to depression. Patients were prospectively evaluated following an acute stroke (N = 309), using a structured psychiatric interview and the Mini-Mental State Examination. Longitudinal evaluations were obtained at 3, 6, 12, and 24 months follow-up in a subset of these patients. During the initial in-hospital evaluation, the frequency and severity of cognitive impairment was significantly greater in patients with major depression compared with nondepressed patients. This effect occurred predominantly in patients with major depression following left hemisphere stroke. The association of depression and cognitive function was strongest during the initial evaluation, but was present for up to 1 year. The year-long effect, however, was evident only in patients with left hemisphere stroke. Patients with both depression and cognitive impairment had a greater duration of depression than depressed patients without cognitive impairment. Depression with cognitive impairment appears to be a phenomenon produced by left hemisphere lesions. This suggests that left hemisphere stroke may produce depression through a different mechanism than lesions in other locations. In addition, the fact that the strongest influence of depression on cognitive function was seen during the initial evaluation suggests that this phenomenon may be mediated by acute or subacute physiological effects of the lesion.

The hospital charts of elderly stroke patients with major depression, as determined by DSM-III-R criteria, who were treated with either methylphenidate (n = 28) or nortriptyline (n = 30) were retrospectively reviewed. Fifty-three percent of the methylphenidate patients experienced complete remission of depressive symptoms. Similarly, 43% of the patients in the nortriptyline group showed remission of depressive symptomatology. Whereas the response rates between the two treatment groups were not significantly different in the patients who did respond to treatment (chi 2 = .608, df = 1, p = NS), the speed of response was significantly better in the methylphenidate group (t[13] = 15.9, p < .001). The average peak response time for the methylphenidate patients was 2.4 days compared to 27 days for the nortriptyline group. This finding is consistent with previous reports suggesting a rapid response to methylphenidate and other psychostimulants, typically between 24 and 72 hours. Adverse side effects, such as cardiac changes, did not differ between groups, generally falling in the mild range of severity. These data suggest that the rapid effects of methylphenidate may be especially useful to speed recovery from depression so that patients can participate more fully in rehabilitation programs.

Sixty surviving patients from a community-based stroke register who had computerised tomography (CT) scan evidence of a single brain lesion were interviewed three to five years after their first ever stroke. Depression (DSM-III-R major depression, partially resolved major depression, and dysthymia) was present in 11 (18%) of the patients and was associated with impaired physical and cognitive functioning, greater age, residence in an institution, absence of a close personal relationship, and larger original brain lesion. Of these variables, only functional dependence (odds ratio 16.4; confidence interval 1.6-170), larger lesion volume (6.6; 1-50), and female sex (8; 1.1-56) remained significantly associated with depression after controlling for all other variables. We conclude that depression in long-term survivors of stroke has many of the same associations as depression in non-stroke elderly populations. Depression in long-term stroke survivors may also be associated with larger original brain lesions, although this requires confirmation in a prospective study.

Apathy and depression are discriminable but related dimensions of behavior. The purpose of this study was to evaluate the source of the overlap between measures of apathy and depression. We evaluated the intercorrelations between the Apathy Evaluation Scale (AES) and the Hamilton Rating Scale for Depression (HamD) in 107 subjects, aged 53-85, who met research criteria for normal aging, left or right cerebral hemisphere stroke, probable Alzheimer's disease, or major depression. We determined the correlation between the individual items on the HamD and the total scores on the AES and the HamD. The HamD items having the strongest correlations with AES total score were diminished work/interest, psychomotor retardation, anergy, and lack of insight. The correlation between AES and HamD total scores was nonsignificant when major depression subjects and these variables most closely related to apathy were excluded from consideration. These findings indicate that the convergence between HamD and AES is attributable to (i) a subset of HamD items which are consistent with the syndrome of apathy and (ii) the fact that major depression is associated with both apathy and depression. Clinical and research applications of these results are discussed.

Despite recent advances in understanding the pathophysiology of poststroke depression, major questions remain. They include the relative importance of lesion location and size and the confounding effects of time since stroke, age, prior history of depression, and cerebral atrophy. To evaluate these issues, we systematically assessed depressive features, functional status, and brain structure with computer tomography scans in 91 men undergoing stroke rehabilitation. Forty percent met DSM-III criteria for major depressive disorder. Mood disturbance was more severe for patients with right than with left hemisphere lesions, correlated with functional disability and lesion size, and was associated with previous history of depression. Age, time since stroke, and atrophy did not correlate with mood. Depression is common in delayed stroke recovery, regardless of lesion location. Because there are no demographic or anatomic features that predict the absence of depression, depression screening should be part of the assessment of all patients undergoing stroke rehabilitation.

The clinical correlates of suicidal thoughts were examined among a group of 301 patients with acute stroke. A total of 20 patients (6.6%) had suicidal thoughts. Previous history of stroke was associated with suicidal thoughts. Suicidal thoughts, however, were not related to severity of physical impairment. Most patients with suicidal thoughts met criteria for major depression. Other risk factors included younger age, poor social support, sensory deficit, and impaired cognitive function. Patients with suicidal plans had depression characterized by social withdrawal and brooding and self blame. Early identification of risk factors including the existence of depression may lead to effective therapeutic intervention.

The authors describe a new scale, the Post-Stroke Depression Rating Scale (PSDRS), specifically constructed to investigate the emotional, affective and vegetative disorders of stroke patients. They also report some preliminary data concerning the validity and reliability of the new scale and of its sections and the first results obtained administering the PSDRS to 68 stroke patients and 10 subjects affected by a "functional" form of major depression. The comparison between the results obtained on the PSDRS by patients classified (on the basis of DSM III diagnostic criteria) as having major depression of either vascular or functional origin seems to show an incomplete overlap between these two forms of depression. In patients classified as having major post-stroke depression, part of the symptomatology seems to be due either to the direct effect of the brain lesion or to the psychological reaction of the patient to the disabilities and handicaps provoked by the lesion.

The validity of observed depression as a criteria for major or minor depression was assessed among 301 patients with acute stroke. Patients who acknowledged a depressed mood or loss of interest (standard depression) were compared to patients who denied depression but were 'observed' to be depressed (non-standard depression) for the clinical correlates of depression. Although standard and non-standard major depressions had some clinical correlates such as increased frequency of female gender and prior psychiatric history, standard major depression patients had a significantly higher frequency of left hemisphere lesions than the non-standard major depression patients. These results support the validity of 'observed' depression as a criteria for major depression but also suggest the possibility that failure to report depressed mood may identify a condition with a different etiology than depression that is recognized and acknowledged. Observed depression, however, was not validated among patients with minor depression since there were no clinical or phenomenological differences from non-depression.

Thirteen vasculopathic nondepressed men, admitted to the hospital 2 weeks earlier because of stroke, 10 age- and weight-matched patients with major depression, and 10 age- and weight-matched normal controls were tested with TRH and on different occasion with the dexamethasone (DEX) suppression test (DST). Patients with stroke were tested again with TRH and DST after 1 year. All subjects were euthyroid. A blunted TSH response to TRH was observed in 77% of vasculopathic patients, 64% of depressed patients, and 27% of controls. Some depressed patients showed serum GH or cortisol increments in response to TRH. Nonsuppression to DEX was observed in 45% of depressed patients and 15% of vasculopathics but not in normal controls. These data indicate that, in contrast to cortisol nonsuppression to DEX, blunted TSH response to TRH has poor diagnostic value as a marker for depression after stroke and may merely represent the expression of neuroendocrine dysfunction associated with cerebral vasculopathy.
