Post-stroke depression (PSD) has an important impact on the quality of life of patients with stroke. We studied 100 stroke patients (mean age+/-SD: 64.6+/-11.6, range: 32-85 years) in the subacute phase (2-5 weeks after onset) and investigated the prevalence and clinical correlates of PSD in the subacute phase. The prevalences of PSD and major depression in the subacute phase evaluated by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, were 20.0 and 5.0%, respectively. These values were lower than those reported in Caucasian studies. The Zung Self-Rating Depression Scale (SDS) did not underestimate the presence of PSD and was thus considered valuable for the initial screening of PSD. However, SDS may overestimate PSD especially in patients with anxiety disorders or somatoform disorders and vice versa. Apathy was observed in 40.2% of patients; however, it was widely distributed and observed even in patients without serious depression.

Data on behavioral changes after thalamic lesion are sparse and largely based on isolated reports of patients with thalamic strokes. However, recent findings suggest that behavioral patterns can be delineated on the basis of the four main arterial thalamic territories. The anterior pattern consists mainly of perseverations and superimposition of unrelated information, apathy, and amnesia. After paramedian infarct, the most frequent features are disinhibition syndromes, with personality changes, loss of self-activation, amnesia, and, in the case of extensive lesions, thalamic "dementia"; this pattern may often be difficult to distinguish from primary psychiatric disorders, especially when neurologic dysfunction is lacking. After inferolateral lesion, executive dysfunction may develop but is often overlooked, although it may occasionally lead to severe long-term disability. After posterior lesion, whereas cognitive dysfunction with neglect and aphasia are well known, no specific behavioral syndrome has been reported. In the future, perfusion CT, functional MRI, and tractography using diffusion imaging in stroke patients may provide a better understanding of the role of the corticothalamic relationship in behavioral changes associated with thalamic stroke.

Neuropsychiatric syndromes are common in the setting of cerebrovascular disease. The most frequent psychiatric syndrome after stroke is depression. Emotionalism and apathy after stroke are also frequent and under-detected symptoms. Treatment principles are broadly similar to those currently used to treat non-organically ill patients. The evidence for pharmacological and psychological treatment for depression after stroke is scant, and of variable quality. Currently there is evidence of efficacy for both tricyclic antidepressants and SSRIs in the management of depression but the latter are better tolerated. Randomized controlled trials of antidepressants for post-stroke emotionalism are positive and this is encouraging. The current evidence base for psychological interventions either as first line or augmentative strategies is too limited and inconclusive to permit definite recommendations. Future studies might include multi-modal interventions using the principles of active case management and pharmacological studies which target both specific neuropsychiatric symptoms and underlying cerebrovascular disorder.

This study was designed to examine the correlation between damage to the basal ganglia or frontal lobe and depression status (both affective and apathetic dimensions) in 243 stroke patients. We assessed the affective dimension in post-stroke depression (PSD) using the Zung Self-rating Depression Scale (SDS) and the apathetic dimension in PSD using the apathy scale (AS). We classified basal ganglia or frontal lobe damage into four groups: no damage, damage to the left side only, damage to the right side only, and damage to both sides. Affective and/or apathetic PSD was found in 126 patients (51.9%). The severity of affective depression (SDS score) was associated with left frontal lobe (but not basal ganglia) damage, and that of apathetic depression (AS score) was related to damage to the bilateral basal ganglia (but not to the frontal lobe). The anatomical correlates of PSD differ depending on the PSD dimension (affective or apathetic) and may explain interstudy differences regarding the association between lesion location and type of PSD.

Apathy is a common feature of a variety of different psychiatric, neurological, and medical disorders. It can be defined as lack of motivation affecting cognitive, emotional, and overt behavioural aspects. Despite being associated with other clinical disorders, apathy can also occur as an independent syndrome (e. g., after brain injuries), now depicting a primary loss of motivation. However, apathy is predominantly assessed within the scope of superordinate psychiatric disorders. As a syndrome-independent scale, the Apathy Evaluation Scale (AES) claims to assess levels of apathy in different disorders. The aim of the present study is to provide German speaking researchers with an authorized German translation of the AES (AES (D)). The scale was evaluated in a sample of 217 subjects, consisting of patients suffering from dementia (n=120), remission-phase schizophrenia (n=20), Parkinson's disease (n=12), stroke (n=28), as well as elderly healthy controls (n=37). Preliminary results concerning the factorial structure, item characteristics, reliability, and construct validity demonstrate favourable statistical properties and suggest that the AESD is comparable to its original. The scale seems well-suited to detect apathy in different clinical groups. Differences between informant sources (clinician interview, self-, and informant ratings) seem to be related to the severity of symptoms or expert practice.

The authors studied patients who presented depression and apathy following intracerebral hemorrhage (ICH). Twelve patients who were admitted in our hospital were divided into two groups according to the presence of post-stroke depression (PSD). Five patients with PSD are in group A, and another seven patients without PSD are in group B. Zung-self depression scale (SDS) and apathy scale were used for screening of depression and apathy. PSD was recognized in 5 (42%) of patients following ICH. Single photon emission tomography (SPECT) suggested the reduction of cerebral blood flow (CBF) in the frontal lobe in all patients of the group A (100%), whereas only 29% of patients of the group B. The reduction of CBF in the frontal lobe might be involved in the mechanism of depression following ICH in subacute stage.

A central aspect of the cerebellar cognitive affective syndrome is the dysregulation of affect that occurs when lesions involve the 'limbic cerebellum' (vermis and fastigial nucleus). In this case series we describe neuropsychiatric disturbances in adults and children with congenital lesions including cerebellar agenesis, dysplasia, and hypoplasia, and acquired conditions including cerebellar stroke, tumor, cerebellitis, trauma, and neurodegenerative disorders. The behaviors that we witnessed and that were described by patients and families included distractibility and hyperactivity, impulsiveness, disinhibition, anxiety, ritualistic and stereotypical behaviors, illogical thought and lack of empathy, as well as aggression and irritability. Ruminative and obsessive behaviors, dysphoria and depression, tactile defensiveness and sensory overload, apathy, childlike behavior, and inability to appreciate social boundaries and assign ulterior motives were also evident. We grouped these disparate neurobehavioral profiles into five major domains, characterized broadly as disorders of attentional control, emotional control, and social skill set as well as autism spectrum disorders, and psychosis spectrum disorders. Drawing on our dysmetria of thought hypothesis, we conceptualized the symptom complexes within each putative domain as reflecting either exaggeration (overshoot, hypermetria) or diminution (hypotonia, or hypometria) of responses to the internal or external environment. Some patients fluctuated between these two states. We consider the implications of these neurobehavioral observations for the care of patients with ataxia, discuss the broader role of the cerebellum in the pathogenesis of these neuropsychiatric symptoms, and revisit the possibility of using cerebellar stimulation to treat psychiatric disorders by enhancing cerebellar modulation of cognition and emotion.

The aim of the present study was to assess the relationship between sitting balance at an early stage and activities of daily living (ADL) function in 452 stroke patients. The effect of sitting balance on the two core elements of depression (apathy and depressive mood) was also examined. The ability to maintain a sitting position for 10 min (10-min sitting balance) was assessed, along with ADL using the Functional Independence Measurement, and psychological status using the Zung Self-rating Depression Scale (depressive mood), Apathy Scale (apathy) and Neuropsychiatric Inventory. Proportional-hazards analysis was used to determine the independent effect of post-stroke depression on functional outcome. Comparisons between sitting balance and psychological status were performed using logistic multiple regression analysis. Cox multiple regression analysis showed that significant differences were obtained for the sitting balance (P < 0.0002) and Mini-Mental State Examination scores (P < 0.02) in all six ADL subscales, and for age in four of the six ADL subscales (Dressing-Upper Body and Dressing-Lower Body, Toileting, Walking). Kaplan-Meier survival curves for reaching independence in ADL subscales showed highly significantly differences in achievement rate and time to reach goal for each subgroup on 10-min sitting balance (with or without assistance) and on age (young, <65; elderly, >/=65 years). Ten-minute sitting balance correlated with depressive mood and apathy. A rapid and simple screening method, 10-min sitting balance was related to scores for two core depressive symptoms, lowered mood and apathy, and was predictive of post-stroke ADL outcomes in the rehabilitation unit along with age.

Anterograde amnesia due to infarction of the anterior fornix is a rare but unique neuropsychological syndrome. Only 2 cases have been reported previously. Lacking focal neurologic deficits, this syndrome is not easy to diagnose. Moreover, it is not fully recognized by the clinicians, making its diagnosis all the more difficult. Here we report a patient of infarction of the anterior fornix and genu of the corpus callosum who developed sudden apathy and anterograde amnesia. Unfortunately, the patient was initially diagnosed and treated as an acute psychiatric disorder by a psychiatrist, and treatment for acute cerebral infarction could not be performed. This case emphasizes the importance of suspecting this syndrome and performing brain magnetic resonance imaging immediately in the patients presenting with anterograde amnesia of sudden onset.
