An unselected cohort of 285 stroke patients, median age 69 years, was studied for correlation between potential risk factors and the one-year incidence of post-stroke depression (PSD). The following factors correlated significantly to PSD a history of previous stroke, a history of previous depression, female gender, living alone and social distress pre-stroke. Further, social inactivity, decrease in social activity, pathological crying and intellectual impairment at one month but not functional outcome correlated to PSD. A multivariate regression analysis showed that intellectual impairment explained 42% of the variance of the mood score. Major depression was unrelated to lesion location. We conclude the etiology of PSD is a complex mixture of pre-stroke personal and social factors and stroke-induced social, emotional and intellectual handicap.

This study represents a first attempt to identify some of the clinical and pathoanatomical correlates of violent outbursts in patients with cerebrovascular accident. Subjects were selected from a population of patients hospitalized with acute stroke. Although we did not have behavioral measures of violent behavior, patients who reported having had violent outbursts were identified based on clinical ratings on a structured interview. Subjects were asked if they had experienced episodes of anger accompanied by behaviors ranging from shouting to violence during the time since their stroke. These patients were compared with controls matched for demographic variables. Violent patients had higher total Present State Exam and Hamilton-D scores. The percentage of patients with cognitive impairment in the angry outburst group (66%) was greater than the control group (22%). Outburst patients had a higher frequency of left-hemisphere lesions (46.7%) compared with controls (29.4%). When lesion volumes were statistically equated, proximity of lesion to the frontal pole was one of the factors related to the self-reported irritable/violent behavior. To determine whether depression explained our findings, we carried out two-way analyses of variance with angry outburst and major depression group membership as factors. Effects of left anterior lesion location and cognitive impairment on violence remained present. These findings suggest that the potential for anger and violence in patients with stroke has multiple clinical and neuropathological correlates, including greater cognitive impairment and left anterior hemisphere lesions.

Approximately 15% of persons age 65 and older have major depression. Risk factors include a recent loss (eg, widowhood or mastectomy), living alone, co-morbidities (eg, hypertension, stroke, cognitive deficits), and drug interactions. Warning signs of depression may include weight loss, sleep problems, feelings of guilt or worthlessness, loss of interest in sexual relations, or changes in activities of daily living. The diagnosis of depression is easy to miss if the physician doesn't look for it, because older persons often don't mention feeling depressed. Yet undetected depression can be deadly for older patients, who have the highest rate of suicide among all Americans. Plans for suicide may be direct or covert, as in not eating or not taking heart medication.

Three hundred one patients were examined for suicidal plans during the acute hospital period following stroke and at 3, 6, 12, and 24 months' follow-up. It was found that 6.6% of patients developed suicidal plans during the initial in-hospital evaluation (acute-onset suicidal plans) and 11.3% of patients developed suicidal plans at 3, 6, 12, or 24 months' follow-up (delayed-onset suicidal plans). The development of both acute and delayed-onset suicidal plans was strongly related to the existence of depressive disorders, especially major depression, and to a prior history of stroke. Acute-onset suicidal plans were also related to premorbid alcohol abuse. Acute-onset suicidal patients had more anterior lesion location and delayed-onset suicidal patients had more posterior stroke lesions. Delayed-onset suicidal plans were not related to alcohol abuse but tended to be associated with greater physical impairment and poorer social support during the acute poststroke period. These data suggest that the etiology of these two types of suicidal plans may be different with acute onset related to biological mechanisms and delayed onset related to psychological mechanisms.

The literature contains sporadic accounts of neurologic complications occurring in patients with Crohn's Disease (CD). The pathogenesis of these is unknown and little has been reported about their incidence. Our review of the medical records of 253 patients with confirmed CD showed that neurologic and neuropsychiatric complications were evident in 84 of the patients, an incidence of 33.2%. In some the association could be casual, but in others the incidence of such complications was higher than that in the general population, suggesting a direct relationship with CD in 19.3%. Our study revealed a variety of neurologic and neuropsychologic events, such as seizure disorder, cerebrovascular accident, headache, peripheral neuropathy, myopathy, and major depression. We believe that an autoimmune phenomenon affecting the small vessels of the central and peripheral nerves may cause the most common neurologic complications of CD.

Owing to the lack of instruments specifically constructed to study emotional and affective disorders of stroke patients, the nature of post-stroke depression (PSD) remains controversial. With this in mind, the authors constructed a new scale, the Post-Stroke Depression Scale (PSDS) which takes into account a series of symptoms and problems commonly observed in depressed stroke patients. The PSDS and the Hamilton Depression Rating Scale (HDS) were administered to a group of 124 patients, who had been classified, on the basis of DSM III-R diagnostic criteria, in the following categories: No depression (n = 32); Minor PSD (n = 47); Major PSD (n = 45). Scores obtained by these stroke patients on the PSDS and on the HDS were compared to those obtained on the same scales by 17 psychiatric patients also classified as major depression on the basis of DSM III-R diagnostic criteria. An analysis of the symptomatological profiles clearly showed that: (1) a continuum exists between the so-called "major" and "minor" forms of PSD; (2) in both groups of depressed stroke patients the depressive symptomatology seems due to the psychological reaction to the devastating consequences of stroke, since the motivated aspects of depression prevailed in depressed stroke patients, whereas the (biologically determined) unmotivated aspects prevailed in patients with a functional form of major depression; and (3) in stroke patients a DSM III-based diagnosis of major PSD could be in part inflated by symptoms (such as apathy and vegetative disorders) that are typical of major depression in a patient free from brain damage, but that could be due to the brain lesion per se in a stroke patient.

In this article the authors describe two different ways in which the relationship between affective disorders and cerebrovascular disease can be studied. First, the occurrence of so called 'post stroke depression' offers an opportunity to study this relationship. Second, neuroradiological investigations in patients with a major depressive disorder can be performed. The authors review the literature on both subjects. Until now, unequivocal conclusions concerning vascular lesions on CT or MRI and depressive features in the elderly cannot be drawn from research data available. Moreover, the so-called Post-stroke depression is still not fully understood. Some difficulties encountered in this area of research are also addressed. The authors suggest a neurological cause for the late onset types of major depressive illness and also suggest that these depressions are phenomenologically different from the early onset subtypes of depressive illness. The post stroke depression also seems to differ phenomenologically from major depression according to DSM-criteria.

The effect of anxiety disorder on recovery from impairment following stroke was examined in 142 patients with acute stroke who had follow-up evaluations. Anxiety disorder significantly interacted with depression to influence the severity and course of depression, outcome of activities of daily living, and social functioning. Anxiety disorder, however, did not affect cognitive impairment, which was influenced only by major depression. These data suggest that the existence of anxiety disorders plays an important role in the prognosis of patients with poststroke depression. These data also suggest that depression and anxiety disorder may have different mechanisms.

In stroke and other medical illnesses, secondary depression may be associated with different factors in women than in men. The authors examined 301 consecutive admissions for acute treatment of cerebrovascular accident for gender differences in depression, psychosocial factors, physical impairment, and lesion location. Women were twice as frequently diagnosed with major depression as men. Women with major depression had a greater frequency of left hemisphere lesions than men. In men, major depression was associated with greater impairment in activities of daily living, and greater severity of depression was associated with greater impairment in daily activities and social functioning. In women, greater severity of depression was associated with prior diagnosis of psychiatric disorder and cognitive impairment. These findings suggest a different nature of poststroke depression in men and women and may have implications for its treatment.

The study of excitatory amino acids (EAAs) has recently resulted in new and fundamental concepts in neuroscience. This progress has led to a growing awareness of the crucial role that brain EAAs systems play in a variety of physiological and pathological processes. The N-methyl-D-aspartate (NMDA) receptor, presently the most well understood subtype of EAAs receptors, has been implicated in crucial physiological processes such as synaptogenesis, learning and memory. Dysfunctions of NMDA receptors seem to play a crucial role in the neurobiology of disorders such as Parkinson's disease, Alzheimer's disease, epilepsy and ischemic stroke. This paper is a review of emerging data indicating that alterations of NMDA receptor function may be pivotal to the pathophysiology of four common psychiatric syndromes: schizophrenia, major depression, posttraumatic stress disorder, and alcoholism. Special emphasis is placed on the current state of development of pharmacological strategies aiming at the modulation of NMDA receptor-mediated neurotransmission in these disorders.
