Sertraline in the treatment of severe aggressiveness in Huntington's disease.
Sertraline, a selective serotonin reuptake inhibitor, was used to treat two consecutive cases of genetically confirmed Huntington's disease in which severe irritability and aggressiveness required inpatient admission. The complete cessation of aggressive behavior in both cases has been maintained on follow-up. This report adds to the literature implicating serotonergic mechanisms in irritability and aggressiveness in both neuropsychiatric and idiopathic psychiatric disorders.

Pathological laughing and crying following stroke: validation of a measurement scale and a double-blind treatment study.
OBJECTIVE: This study was undertaken to test the reliability and validity of the Pathological Laughter and Crying Scale and the effectiveness of nortriptyline treatment for patients with emotional lability following stroke. METHOD: Eighty-two patients with ischemic brain injury-54 who had been hospitalized with acute stroke and 28 others who requested treatment for pathological laughing and crying--were given standardized psychiatric and neurological assessments and then administered the Pathological Laughter and Crying Scale. The 54 acute stroke patients were used to evaluate the Pathological Laughter and Crying Scale, and the 28 patients with pathological emotional display were randomly assigned to nortriptyline treatment or placebo in a 6-week double-blind trial to assess the efficacy of a tricyclic antidepressant in treatment of this disorder. RESULTS: The interrater reliability on the Pathological Laughter and Crying Scale for a subgroup of 15 patients was 0.93, and the test-retest reliability of the scale was excellent. After 4 and 6 weeks of treatment, scores on the Pathological Laughter and Crying Scale showed significantly greater improvement in the 14 patients given nortriptyline than in the 14 given placebo. Although almost one-half of these patients also had major depression, the improvement in emotional lability was independent of depression status. In addition, response to treatment was not significantly affected by lesion location or time since stroke. CONCLUSIONS: The severity of symptoms in pathological emotional display can be reliably quantified with the Pathological Laughter and Crying Scale, and treatment with nortriptyline can effectively ameliorate this emotional disorder.

Depression following myocardial infarction.
OBJECTIVE: Although many investigators have studied mood disorders following myocardial infarction, the prevalence, severity, and persistence of depression have been disputed, and standard rating scales and criteria for depressive disorders have infrequently been utilized. The authors' goal was to determine how frequently depressive disorders occur after myocardial infarction, and to investigate predisposing factors for such disorders. METHOD: Structured clinical interviews were administered to 129 inpatients within ten days of myocardial infarction. Patients were also evaluated using standardized rating scales for depression, social function, cognition, and physical impairment. DSM-III diagnoses were derived from the structured interview. RESULTS: Major depressive syndromes were present in 19 percent (n = 25) of the patients and were associated with prior history of mood disorder, female sex, large infarcts, and functional physical impairment. CONCLUSION: Major depression is common in the acute post-myocardial infarction period. Such disorders confer significant psychiatric morbidity and, if sustained, require psychiatric intervention.

The impact of poststroke depression on recovery in activities of daily living over a 2-year follow-up.
The impact of clinically diagnosed depression on recovery in activities of daily living over a 2-year follow-up was examined in a prospective study of 63 stroke patients. Although impairment in activities of daily living, neurologic diagnoses and findings, lesion location and volume as measured on computed tomographic scan, demographic variables, cognitive impairment, and social functioning were comparable between depressed (n = 25) and nondepressed (n = 38) patients during their acute hospitalization, the two groups had different patterns of recovery in activities of daily living. At 2 years after suffering a stroke, patients with an in-hospital diagnosis of depression (either major or minor depression) were significantly more impaired in both physical activities and language functioning than were non-depressed patients. Among patients with major depression, this disparity in the recovery profile was present even after the depression had remitted. This study emphasizes the need for early recognition and treatment of poststroke depression.

Apathy and indifference in patients on fluvoxamine and fluoxetine.
Apathy, indifference, loss of initiative, or disinhibition (without concurrent sedation or hypomania) were observed among five patients receiving the serotonin reuptake blocking antidepressants fluvoxamine or fluoxetine. These effects appeared to be dose related. They disappeared rapidly when the dose of fluvoxamine, which has a short half-life, was reduced. Fluoxetine, which has a long half-life, was more difficult to titrate. A possible relationship between mild drug-induced indifference and the therapeutic effects of serotonin reuptake blocking medication in anxiety disorders is discussed.

A two year longitudinal study of poststroke mood disorders: prognostic factors related to one and two year outcome.
In a prospective study of mood disorders in 103 stroke patients, we examined the predictive value of affective, cognitive, social and neurologic variables obtained in-hospital and at six months poststroke in terms of outcome as determined by the same measures at one and two years follow-up. The following factors were found to have prognostic significance: 1) Lesion Location: proximity of the lesion on CT scan to the frontal pole in patients with left anterior infarcts showed a strong positive relationship with severity of depression at one year but not at two years poststroke. 2) Affective Status: depression (in-hospital and at 6 months) strongly predicted depression at one year but not at two years poststroke. Additionally, in-hospital depression significantly correlated with physical impairment at two years, while depression at six months bore a moderate relationship to physical impairment at one year. 3) Physical Impairment: impairment in activities of daily living in-hospital bore a modest relationship to depression at one year while such impairment at six months correlated strongly with depression at both one and two years. These findings may reflect the natural course of major depression which remits between one and two years poststroke. Although stroke lesion location is the strongest predictor of subsequent depression, there appears to be a reciprocal relationship between physical impairment and depression (i.e., depression predicts impairment and impairment predicts depression). Since poststroke depressions are amenable to therapeutic intervention, these prognostic factors may have implications for the treatment and rehabilitation of stroke patients.

Olfactory recognition: differential impairments in early and late Huntington's and Alzheimer's diseases.
Forty-two patients with senile dementia of the Alzheimer type (SDAT), 38 patients with Huntington's disease (HD) and matched normal controls were administered tests of olfactory, verbal, and visual recognition after being screened for normal olfactory discrimination. Early-affected Huntington's patients (EHD) with minimal chorea or cognitive deficit displayed marked deficits in olfactory recognition despite normal verbal and visual performance, even after correction for task difficulty, suggesting involvement of olfactory brain regions early in the disease process. In the early Alzheimer's group (EAD), marked deficits were seen on all recognition modalities indicating more global impairment. Both overall (early plus late) patient groups were impaired relative to controls on all recognition tasks, with the olfactory paradigm being most affected.

Sex dependent behavioral response to frontal cortical suction lesions in the rat.
Previous reports indicate that male rats given right (but not left) frontal cortical suction lesions develop hyperactivity accompanied by cortical norepinephrine depletions. In this study, female rats given such lesions to either hemisphere developed bilateral cortical norepinephrine depletions but no hyperactivity. Right lesion male rats developed both catecholamine depletions and hyperactivity. Thus, the lateralized hyperactivity response to these cortical lesions is sex-dependent and may involve sex differences in subcortical neural pathways.

Lateralized response to cortical injury in the rat: interhemispheric interaction.
This study was conducted to investigate the role of interhemispheric interaction in the production of spontaneous hyperactivity following right but not left frontal cortical suction lesions in the rat. Bilateral lesions, either simultaneous or left followed 1 week later by right, led to spontaneous hyperactivity and bilateral depletions of cortical norepinephrine concentrations. Rats given corpus callosum sectioning as neonates and frontal cortical suction lesions as adults developed spontaneous hyperactivity only when the right hemisphere was injured. These data suggest that lateralized spontaneous hyperactivity as elicited by small suction lesions of the right hemisphere does not depend on interhemispheric release or interaction and that at least the cortical mechanism is in the right hemisphere itself.

Two-year longitudinal study of post-stroke mood disorders: comparison of acute-onset with delayed-onset depression.
Patients who developed post-stroke depression 3 to 24 months after hospital discharge (N = 21) were compared with patients who developed depression during hospitalization (N = 26) and patients who never developed depression over 24 months of follow-up (N = 15). During the acute hospitalization and at follow-up, the three groups were not significantly different in their demographic characteristics, neurological impairment, intellectual impairment, or quality of social support. The acute depression group, however, showed an increased correlation between impairment and depression from hospitalization to follow-up. Findings suggest that impairment does not produce depression, but, once depression occurs, it may interact with impairment to influence post-stroke recovery.

Depression influences intellectual impairment in stroke patients.
Patients with ischaemic lesions of the left cerebral hemisphere were examined for depression and intellectual impairment: in non-depressed patients, the severity of impairment was related to both lesion volume and location, as assessed by CT scan analysis. Cognitive impairment in patients with major depression was greater than predicted by lesion volume alone, and when patients were matched for severity of impairment, depressed patients had smaller lesion volumes than the non-depressed. After six months, non-depressed patients had significantly less cognitive impairment than depressed patients who showed no improvement. Both depression and lesion volume were significantly and independently related to cognitive impairment. These findings suggest that post-stroke depression can produce a true dementia in its own right, and that treatment of post-stroke depression might benefit cognitive function.

A two-year longitudinal study of poststroke mood disorders. In-hospital prognostic factors associated with six-month outcome.
In a prospective study of mood disorders in stroke patients, variables obtained during the acute hospitalization were examined for their relationship to outcome at either 3- or 6-month follow-up. Distance of the lesion on computerized axial tomography scan from the frontal pole in patients with left anterior infarcts was significantly associated with severity of depression at 3 and 6 months poststroke. In addition, intellectual and functional physical impairment in-hospital were significantly correlated with severity of depression and social functioning scores at 3 and 6 months poststroke. Thus, patients who develop depression during the first 6 months poststroke may be responding to the severity of their impairment whereas the patients who develop depressions during the acute poststroke period may have a neuroanatomical and neurophysiological basis for their depression. Although other explanations might be proposed, the dynamic nature of the relationship between depression and associated variables during the first 6 months poststroke indicates that etiology of poststroke depression may be different depending upon the time of onset of the depression after brain injury.

Mood disorders in left-handed stroke patients.
Thirty left-handed patients hospitalized for stroke were examined for mood disorders. Patients with left hemisphere lesions and nondominant hand impairments had significantly higher depression scores and more depressive diagnoses than patients with right hemisphere lesions and dominant hand impairments. Major depression was strongly associated with left anterior brain injury, and depression severity was significantly correlated with proximity of the lesion on CAT scan to the left frontal pole. These findings are almost identical to previously reported results from right-handed patients and suggest that cerebral lateralization of poststroke mood disorders may be independent of cerebral motor dominance and language dominance.

The dexamethasone suppression test and mood following stroke.
Dexamethasone suppression tests (DSTs) were given to 65 acute and chronic stroke patients. For patients who had had a stroke less than 1 year earlier, nonsuppression on the DST was significantly associated with the presence of poststroke depression. The authors, who used the DSM-III symptom criteria for major depression, found that DST sensitivity was 67% but specificity was only 70%. False positive tests in the stroke patients seemed related to large lesion volume. The DST, although of limited clinical utility in this population because of false positive tests, may help define more homogeneous subtypes of poststroke depression for research.
