Abstract
Poststroke depression significantly affects health and quality of life of stroke patients. This study evaluates the role of social support in influencing poststroke depression. The literature search was conducted in electronic databases and study selection was based on precise eligibility criteria. The prevalence rates reported by individual studies were pooled. A meta-analysis of standardized mean differences (SMD) in social support between depressed and non-depressed stroke patients was performed. The odds ratios and correlation coefficients showing the relationship between social support and depression were pooled to achieve overall estimates. Twenty-five studies (9431 patients) were included. The prevalence of depression was 36% [95% confidence interval (CI): 28, 45]. Patients with poststroke depression had significantly lower social support in comparison with patients with no or lower levels of depression [SMD in social support scores -0.338 (95% CI: -0.589, -0.087); p = 0.008]. The odds of depression were lower in patients receiving higher levels of social support [OR 0.82 (95% CI: 0.69, 0.95)] but were higher in patients who were receiving weaker social support [OR 5.22 (95% CI: -0.87, 11.31)]. A meta-analysis of correlation coefficients found a significantly inverse correlation between social support and poststroke depression [r -0.336 (95% CI: -0.414, -0.254)]. Poststroke depression has a significant independent inverse association with social support.

Post-stroke depression and lesion location: a systematic review. J Neurol 2014; 262:81-90.

Abstract
Post-stroke depression (PSD) is a frequent problem in stroke rehabilitation. Several studies have evaluated association between the lesion location and the risk of depression. Different conclusions and contradictory findings have been published. The aim of the present study was to perform a systematic meta-analysis to evaluate the relationship between PSD and lesion location. We researched PubMed, ISI Web of Science, EMBASE, and systematically reviewed available publications reporting investigations on stroke location and risk of PSD. Subgroup analyses were performed according to the time since stroke onset to assessment for PSD or the source of patients. Odds ratios (ORs) and 95 % confidence intervals (CIs) were used for pooled analyses. Heterogeneity was assessed with Cochran's Q test and I (2) test. Begg's funnel plot and Egger's test were used to examine the publication bias. A total of 43 studies involving 5,507 patients suffering from stroke were included in this meta-analysis. The pooled OR with 95 % CI for the overall association of stroke location and depression risk was 0.99 (0.88-1.11). Subgroups analyses highlighted that only studies with subacute post-stroke group (1-6 months) showed a statistical association between right hemisphere stroke and risk of depression (OR = 0.79, 95 % CI 0.66-0.93). This systematic review offered no support for the hypothesis that lesion of the left hemisphere was associated with an increased risk of depression after stroke. We only find significant association between right hemisphere stroke and incidence of depression for studies within subacute post-stroke phase.

Abstract
OBJECTIVE The aims of this study were to determine the dominant affective temperament changes in stroke survivors and whether temperament affects the disability. METHODS A total of 63 stroke patients were included in this study. Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire was used to determine the dominant affective temperament (depressive, hyperthymic, cyclothymic, irritable or anxious). The disability level was measured with the Barthel index (BI). RESULTS Depressive temperament (17.5%) and anxious temperament (12.7%) were the most common dominant affective temperaments. The frequencies of irritable, cyclothymic and hyperthymic temperaments were 4.8, 3.2 and 0%, respectively. The mean BI score was 78.1 ± 18.3 in patients with depressive temperament and 67.4 ± 28.4 in patients without depressive temperament (p = 0.403). The mean BI score was 78.1 ± 15.3 in patients with anxious temperament and 68.0 ± 28.3 in patients without anxious temperament (p = 0.541). Multiple linear regression analysis indicated that BI score was not associated with affective temperament changes. CONCLUSION The results of the current study suggest that depressive and anxious temperaments are the most common affective temperaments and that there appears to be no association between disability level and dominant affective temperament in stroke survivors.

Abstract
BACKGROUND/AIMS A third of individuals are depressed following stroke. A similar proportion have aphasia. The extent of their inclusion in depression following stroke studies affects the generalizability of findings. METHODS We systematically reviewed published studies (to December 2005) that diagnosed depression following stroke. We identified aphasia screening methods, aphasia exclusion and inclusion criteria and respective numbers of individuals with aphasia. RESULTS Of 129 studies (n = 19,183), aphasia screening methods were only reported by 57 (31 described a published aphasia-specific tool). No mention of aphasia was made in 13 studies. Most studies (92, 71%) reported some exclusion of people with aphasia (49 reported how many: n = 3,082, range = 2-554). Almost half of the studies (60, 47%) actually reported participants with aphasia (37 specified numbers: n = 829, range = 5-60). Aphasia exclusion or inclusion was not associated with sample source (community, acute hospital, other) or study purpose (observation, intervention, screening). Studies that reported screening for aphasia were more likely to describe aphasia exclusion and inclusion criteria and include participants with aphasia. CONCLUSION Aphasia screening, exclusion and inclusion criteria reporting across studies of depression following stroke has been highly inconsistent. This impairs the interpretation of generalizability. Improved aphasia screening and reporting of exclusion and inclusion criteria are urgently recommended.

Abstract
The stress response is mediated by the hypothalamo-pituitary-adrenal (HPA) system. Activity of the corticotropin-releasing hormone (CRH) neurons in the hypothalamic paraventricular nucleus (PVN) forms the basis of the activity of the HPA-axis. The CRH neurons induce adrenocorticotropin (ACTH) release from the pituitary, which subsequently causes cortisol release from the adrenal cortex. The CRH neurons co-express vasopressin (AVP) which potentiates the CRH effects. CRH neurons project not only to the median eminence but also into brain areas where they, e.g., regulate the adrenal innervation of the autonomic system and affect mood. The hypothalamo-neurohypophysial system is also involved in stress response. It releases AVP from the PVN and the supraoptic nucleus (SON) and oxytocin (OXT) from the PVN via the neurohypophysis into the bloodstream. The suprachiasmatic nucleus (SCN), the hypothalamic clock, is responsible for the rhythmic changes of the stress system. Both centrally released CRH and increased levels of cortisol contribute to the signs and symptoms of depression. Symptoms of depression can be induced in experimental animals by intracerebroventricular injection of CRH. Depression is also a frequent side effect of glucocorticoid treatment and of the symptoms of Cushing's syndrome. The AVP neurons in the hypothalamic PVN and SON are also activated in depression, which contributes to the increased release of ACTH from the pituitary. Increased levels of circulating AVP are also associated with the risk for suicide. The prevalence, incidence and morbidity risk for depression are higher in females than in males and fluctuations in sex hormone levels are considered to be involved in the etiology. About 40% of the activated CRH neurons in mood disorders co-express nuclear estrogen receptor (ER)-alpha in the PVN, while estrogen-responsive elements have been found in the CRH gene promoter region, and estrogens stimulate CRH production. An androgen-responsive element in the CRH gene promoter region initiates a suppressing effect on CRH expression. The decreased activity of the SCN is the basis for the disturbances of circadian and circannual fluctuations in mood, sleep and hormonal rhythms found in depression. Neuronal loss was also reported in the hippocampus of stressed or corticosteroid-treated rodents and primates. Because of the inhibitory control of the hippocampus on the HPA-axis, damage to this structure was expected to disinhibit the HPA-axis, and to cause a positive feedforward cascade of increasing glucocorticoid levels over time. This 'glucocorticoid cascade hypothesis' of stress and hippocampal damage was proposed to be causally involved in age-related accumulation of hippocampal damage in disorders like Alzheimer's disease and depression. However, in postmortem studies we could not find the presumed hippocampal damage of steroid overexposure in either depressed patients or in patients treated with synthetic steroids.

Abstract
Corticotropin-releasing hormone (CRH) plays a central role in the regulation of the hypothalamic-pituitary-adrenal (HPA)-axis, i.e., the final common pathway in the stress response. The action of CRH on ACTH release is strongly potentiated by vasopressin, that is co-produced in increasing amounts when the hypothalamic paraventricular neurons are chronically activated. Whereas vasopressin stimulates ACTH release in humans, oxytocin inhibits it. ACTH release results in the release of corticosteroids from the adrenal that, subsequently, through mineralocorticoid and glucocorticoid receptors, exert negative feedback on, among other things, the hippocampus, the pituitary and the hypothalamus. The most important glucocorticoid in humans is cortisol, present in higher levels in women than in men. During aging, the activation of the CRH neurons is modest compared to the extra activation observed in Alzheimer's disease (AD) and the even stronger increase in major depression. The HPA-axis is hyperactive in depression, due to genetic factors or due to aversive stimuli that may occur during early development or adult life. At least five interacting hypothalamic peptidergic systems are involved in the symptoms of major depression. Increased production of vasopressin in depression does not only occur in neurons that colocalize CRH, but also in neurons of the supraoptic nucleus (SON), which may lead to increased plasma levels of vasopressin, that have been related to an enhanced suicide risk. The increased activity of oxytocin neurons in the paraventricular nucleus (PVN) may be related to the eating disorders in depression. The suprachiasmatic nucleus (SCN), i.e., the biological clock of the brain, shows lower vasopressin production and a smaller circadian amplitude in depression, which may explain the sleeping problems in this disorder and may contribute to the strong CRH activation. The hypothalamo-pituitary thyroid (HPT)-axis is inhibited in depression. These hypothalamic peptidergic systems, i.e., the HPA-axis, the SCN, the SON and the HPT-axis, have many interactions with aminergic systems that are also implicated in depression. CRH neurons are strongly activated in depressed patients, and so is their HPA-axis, at all levels, but the individual variability is large. It is hypothesized that particularly a subgroup of CRH neurons that projects into the brain is activated in depression and induces the symptoms of this disorder. On the other hand, there is also a lot of evidence for a direct involvement of glucocorticoids in the etiology and symptoms of depression. Although there is a close association between cerebrospinal fluid (CSF) levels of CRH and alterations in the HPA-axis in depression, much of the CRH in CSF is likely to be derived from sources other than the PVN. Furthermore, a close interaction between the HPA-axis and the hypothalamic-pituitary-gonadal (HPG)-axis exists. Organizing effects during fetal life as well as activating effects of sex hormones on the HPA-axis have been reported. Such mechanisms may be a basis for the higher prevalence of mood disorders in women as compared to men. In addition, the stress system is affected by changing levels of sex hormones, as found, e.g., in the premenstrual period, ante- and postpartum, during the transition phase to the menopause and during the use of oral contraceptives. In depressed women, plasma levels of estrogen are usually lower and plasma levels of androgens are increased, while testosterone levels are decreased in depressed men. This is explained by the fact that both in depressed males and females the HPA-axis is increased in activity, parallel to a diminished HPG-axis, while the major source of androgens in women is the adrenal, whereas in men it is the testes. It is speculated, however, that in the etiology of depression the relative levels of sex hormones play a more important role than their absolute levels. Sex hormone replacement therapy indeed seems to improve mood in elderly people and AD patients. Studies of rats have shown that high levels of cumulative corticosteroid exposure and rather extreme chronic stress induce neuronal damage that selectively affects hippocampal structure. Studies performed under less extreme circumstances have so far provided conflicting data. The corticosteroid neurotoxicity hypothesis that evolved as a result of these initial observations is, however, not supported by clinical and experimental observations. In a few recent postmortem studies in patients treated with corticosteroids and patients who had been seriously and chronically depressed no indications for AD neuropathology, massive cell loss, or loss of plasticity could be found, while the incidence of apoptosis was extremely rare and only seen outside regions expected to be at risk for steroid overexposure. In addition, various recent experimental studies using good stereological methods failed to find massive cell loss in the hippocampus following exposure to stress or steroids, but rather showed adaptive and reversible changes in structural parameters after stress. Thus, the HPA-axis in AD is only moderately activated, possibly due to the initial (primary) hippocampal degeneration in this condition. There are no convincing arguments to presume a causal, primary role for cortisol in the pathogenesis of AD. Although cortisol and CRH may well be causally involved in the signs and symptoms of depression, there is so far no evidence for any major irreversible damage in the human hippocampus in this disorder.

Abstract
Our understanding of the relationship between the neuroanatomic loci of brain damage and the incidence of post-stroke depression (PSD) is not complete. Many studies have investigated this relationship and the evidence is conflicting. With the purpose of gaining a consistent, strong, and credible conclusion on the relationship between PSD and the loci of brain damage, a meta-analysis was used in this study to systematically reanalyze the findings of related studies and to investigate the sources of heterogeneity among study results. The key words "stroke or cerebrovascular" and "depression or mood or affective" were entered into the MEDLINE, PsycINFO, and EMBASE databases to search for relevant studies. The references cited in the studies found were also used to locate additional studies. For each eligible study, the important study characteristics were recorded, and the effect sizes of the relationship between PSD and lesion location were computed. Furthermore, we conducted subgroup analyses to explore the heterogeneity among study results. A total of 3,668 patients participating in 52 studies were included in this meta-analysis. There was a weak relationship between PSD and right hemisphere lesion. The major sources of heterogeneous study results included systematic exclusion of patients with language dysfunction and use of different assessors and instruments for diagnosing depression. Future efforts should aim to enhance standards for reporting studies, improve assessment tools for assessing depression of aphasic patients, and adopt appropriate study methodologies for investigating the relationship between PSD and lesion location.

Abstract
Patients who have had stroke are at significant risk for various neuropsychiatric illnesses. The most common and important of these are poststroke depression and poststroke dementia (attributable to vascular dementia, Alzheimer's dementia, or a combination of mechanisms). Poststroke neuropathology may lead some patients to experience concurrent and "overlapping" mood and cognitive symptoms. Less frequently, poststroke anxiety disorders, psychosis, isolated pathologic expressions of emotions, and apathy or fatigue may be encountered. The authors review the current literature on poststroke neuropsychiatry and offer an integrated approach to pathophysiologic concepts and clinical surveillance, screening, diagnosis, and evidence-based pharmacologic and nonpharmacologic intervention for these clinical problems on the clinical boundary between neurology and psychiatry.

Abstract
Background—
It has been hypothesized that poststroke depression (PSD) results from left hemisphere lesions. However, attempts to systematically review the data investigating lesion location and PSD have yielded conflicting results. We sought to investigate the methodological differences across the literature studying the relationship between lesion location and PSD.
Summary of Review—
A MEDLINE literature search to retrieve articles investigating the association between PSD and lesion location was performed. Information sought included source population of samples, definition of depression, standardized measurement of stroke and depression, blinding, time since stroke onset, and study design. Odds ratios (ORs) and 95% CIs were calculated with the use of Review Manager and MetaView statistical software. Twenty-six original articles were reviewed. Much of the heterogeneity across studies reflected differences in methodology. The direction of association between left hemisphere lesion location and PSD varied depending on whether patients were sampled as inpatients (OR, 1.36; 95% CI, 1.05 to 1.76) or from the community (OR, 0.60; 95% CI, 0.39 to 0.92). Change in the direction of association was also observed across assessment interval from the acute stroke (OR, 2.14; 95% CI, 1.50 to 3.04) to the chronic stroke (OR, 0.53; 95% CI, 0.30 to 0.93) phase. Differences in the measurement of depression, study design, and presentations of results also may have contributed to the heterogeneity of the findings.
Conclusions—
Several key initiatives should be addressed before future research is undertaken, including the development of a comprehensive measure of PSD, optimal poststroke assessment intervals, and determination of a representative population reference.

Abstract
PURPOSE OF REVIEW The most recent reports on emotional consequences of stroke are hereby reviewed and analyzed. In particular the interpretation of some neurological presentations found in stroke patients, such as athymormia, dysprosody, emotional incontinence and emotional blunting is discussed. As current theories on mental functions do not provide satisfactory explanations for the above syndromes, a novel interpretative framework is proposed, based on neuropsychological experimental data on the 'mirror system'. RECENT FINDINGS Recent findings support both the fundamental role of the mirror system in imitative processes as well as the relevance of imitation for the emotional part of human personality and behavior. SUMMARY The mirror system appears to be of paramount relevance for empathy and social behavior. The model of analysis-by-synthesis is here discussed, together with neurological presentations resulting from stroke induced impairments of the mirror system. Speculations for further researches are also proposed.

Abstract
A comprehensive evidence-based review of stroke rehabilitation was created to be an up-to-date review of the current evidence in stroke rehabilitation and to provide specific conclusions based on evidence that could be used to help direct stroke care at the bedside and at home. A literature search using multiple data-bases was used to identify all trials from 1968 to 2001. Methodological quality of the individual randomized controlled trials was assessed using the Physiotherapy Evidence Database (PEDro) quality assessment scale. A five-stage level-of-evidence approach was used to determine the best practice in stroke rehabilitation. Over 403 treatment-based articles investigating of various areas of stroke rehabilitation were identified. This included 272 randomized controlled trials.

Abstract
Stroke represents a major health problem in the United States and most European and Asian countries. Depression is probably the most common and serious emotional disorder following stroke. Post-stroke depression (PSD) has frequently been overlooked and left untreated. Prevention of PSD or successful intervention in the early phase may prevent premature deaths as well as facilitate rehabilitation, reduce costs, and improve quality of life. Stroke is clearly a risk factor for depression, and recent evidence suggests that depression increases the risk for stroke, although the mechanisms by which depression leads to stroke remain to be clarified. Once PSD has developed, numerous studies have documented its adverse effect on cognitive recovery, physical recovery, and mortality. Taken together, these studies support the necessity of identifying and treating this condition.

Abstract
BACKGROUND There is conflicting evidence on the hypothesis that the risk of depression after stroke is influenced by the location of the brain lesion. We undertook a systematic review to examine the hypotheses that depression is more commonly associated with left-hemisphere strokes than with right-hemisphere strokes and with lesions of the left anterior brain than with other regions. METHODS We did a computer-aided search of MEDLINE, BIDS ISI, and PsychLit databases supplemented by hand searches of key journals. We included all reports on the association of depression after stroke with the location of the brain lesion. Studies were systematically and independently examined by two investigators. Fixed-effects and random-effects meta-analyses were done. FINDINGS 143 reports were identified by the search strategy. 48 were eligible for inclusion. Not all reports included original data. Only two reports of original data supported the hypotheses and seven clearly did not. The pooled (random-effects) relative risk of depression after a left-hemisphere stroke, compared with a right-hemisphere stroke, was 0.95 (95% CI 0.83-1.10). For depression after a left anterior lesion compared with all other brain areas the pooled (random-effects) relative risk was 1-17 (0.87-1.62). Restriction of the analyses to reports from high-quality studies or major depressive disorder did not substantially affect the findings. Nor were they affected by stratification of the time between stroke and the assessment of depression. Multiple publications from the same samples of patients were apparent. INTERPRETATION This systematic review offered no support for the hypothesis that the risk of depression after stroke is affected by the location of the brain lesion.

Abstract
OBJECTIVES To examine the relationship between depression and cerebrovascular disease in three distinct settings: depression in established cerebrovascular disease, cerebrovascular disease in established depression and depression in vascular dementia. METHODS Medline, EMBASE, PsychLit and PsychInfo databases were scanned to locate relevant articles. Data were also extracted from other articles, cited by those articles generated from the above databases. RESULTS Using operational criteria, the prevalence of depression is higher than controls only within the first year after stroke, but most studies have not employed control groups. The prevalence of depression in vascular dementia compared with Alzheimer's disease is higher in the majority of studies, but matching for sociodemographic factors and severity of cognitive impairment has been inconsistent. An association between frontal/subcortical cerebrovascular lesions and depression in later life has been observed, but there may be methodological flaws underlying this observation in some computerized tomography studies. CONCLUSION There is some evidence that cerebrovascular disease has an aetiopathological role in late life depression. The increased likelihood of damage to frontal/subcortical brain circuitry following stroke, transient ischaemia and hypertension may explain the high prevalence of depression in older people with vascular risk factors. More valid definitions of lesion location and the use of appropriately matched control groups would seek to clarify this issue. The extrapolation to care settings from the high prevalence of depression accompanying cerebrovascular disease and the prolongation of disability in depressed people with stroke, suggests closer liaison between old age psychiatrists, neurologists and physicians caring for the elderly.

Abstract
Patients were consecutively enrolled in a cross-sectional study to determine the severity of depressive symptoms and the rate of treated depression in a patient population returning to a stroke outpatient service during a 10-week period for a regular check-up examination after their stroke. Of the 143 stroke patients, 119 fulfilled the inclusion criteria. The 13-item Beck Depression Inventory was used to screen for depressive symptoms. The score was at least 5 in 53%, 10 or above in 26%, and 15 or above in 11% of patients. Severity of depressive symptoms did not depend on gender, age, time elapsed from stroke, or the site of the cerebral lesion. Most patients with considerable depressive symptoms did not receive antidepressant medication at the time of the screening.

Abstract
Recent accounts of major depression have tended to focus on dysfunction of frontothalamic-striatal reentrant circuits as a possible source of the disorder. Evidence of frontostriatal involvement in unipolar major depression from lesion and neuropsychological studies, and functional and structural imaging studies is examined. The high incidence of depressive symptomatology following left frontal and basal ganglia lesions implicate these as possible sites of dysfunction. Neuropsychological evidence indicates similar deficits in patients with major depression, perhaps with dorsolateral prefrontal deficits most prominent. Structural imaging studies report frontal and basal ganglia (BG) abnormalities particularly in cases of late-age onset depression. Resting state functional imaging studies show deficits in dorsolateral, anterior cingulate (medial frontal), and BG structures. Activation imaging studies show less consistent evidence of dorsolateral deficit, while anterior cingulate deficit is more consistently demonstrated. Variability in findings across studies may reflect differences between subtypes of depression and differences in methodology. Possible involvement of the BG in the psychomotor retardation of depression is examined. It is concluded that, while there is evidence of frontostriatal deficit in major depression, the exact nature of such deficits is uncertain. Issues such as component vs. system dysfunction need to be addressed.
