Depression-executive dysfunction syndrome in stroke patients.

OBJECTIVE: It has been suggested that executive dysfunction could be the core defect in patients with geriatric or vascular depression, and that this depression-dysexecutive syndrome (DES) might be related to frontal-subcortical circuit dysfunction. The authors tested this hypothesis in 158 poststroke patients, of whom 21 had both depression and executive dysfunction. METHODS: In this cross-sectional cohort study, a neurological, psychiatric, and neuropsychological examination was carried out 3 months after ischemic stroke, and brain infarcts, white-matter changes, and brain atrophy were recorded by MRI. RESULTS: The 21 patients with DES had significantly more brain infarcts affecting their frontal-subcortical circuit structures than the 137 patients without DES, or the 41 patients with depression but without executive dysfunction. Patients with DES also had more severe depressive symptoms and worse psychosocial functioning, and they coped less well in complex activities of daily living. CONCLUSIONS: DES is a valid concept and may define a subgroup of poststroke patients with frontal-subcortical pathology and with distinct prognosis and treatment options.

Temozolomide treatment in glioma--experiences in two university hospitals in Finland.

Thirty-two patients with relapsing glioma were treated with temozolomide in two university hospitals in Finland. One patient (3%) had complete response and 9 (28%) partial response, with 8 patients (25%) showing stable disease. Median progression-free survival for these 18 patients (56%) was 7 months (range 2-11+). The remaining either had progressive disease (25%) or only clinical evaluation (19%). Karnofsky score improved in 34% of patients and decreased in 3%. Symptoms were alleviated in 44% and deteriorated in 9%. Grade 3-4 toxicity was detected in 9% of the patients. Only 4% of the days in treatment were spent in hospital. An average 1.8 neuroradiological investigations, 6.9 laboratory visits, and 5.3 visits to the oncologist were made. This study confirms that temozolomide has positive effects on the outcome of often heavily pretreated glioma patients. High drug costs are compensated by prolonged home care and even the possibility to maintain working capacity.

Clinical features of MRI-defined subcortical vascular disease.

BACKGROUND AND PURPOSE: Vascular cognitive impairment and vascular dementia are now seen to extend much beyond the traditional multi-infarct dementia.A more homogeneous subtype is the subcortical ischemic vascular disease (SIVD). We applied magnetic resonance imaging (MRI) criteria based on research criteria for SIVD in a large cohort of patients with ischemic stroke. We compared clinical features of patients with SIVD and patients with other stroke type. SUBJECT AND METHODS: The study group comprised 337 of 486 consecutive patients aged 55 to 85 years who 3 months after ischemic stroke completed a comprehensive neuropsychological test battery and MRI, including structured medical, neurologic, and laboratory evaluations; clinical mental status examination; interview of a knowledgeable informant; detailed history of risk factors; and evaluation of stroke type, localization, and syndrome. RESULTS: Patients with SIVD (n = 86) more often had a history of progressive cognitive decline (22.8% vs. 6.9%, P = 0.0002), walking disorder before stroke (27.9% vs. 2.0%, P = 0.02), and urinary difficulties (12.8% vs. 5.6%, P = 0.028) in comparison with patients with other stroke type (n = 251). Of the study population, 107 (31.8%) had DSM-III dementia. The patients with SIVD more often had DSM-III dementia (40.7% vs. 28.7%, P = 0.04), had less severe stroke as measured by Scandinavian Stroke Scale (56.6 vs. 55.1, P = 0.03), were more dependent in activities of daily living (ADL) functions as measured by FAQ scale (8.9 vs. 5.4, P = 0.001), were more dependent in instrumental activities of daily living (IADL) functions as measured by the Lawton scale (5.5 vs. 6.3, P = 0.01), and were more depressed as measured by the Beck Depression Inventory (11.8 vs. 8.4, P = 0.0003) poststroke than the patients without SIVD. The main cognitive domain that differentiated the patients with SIVD from those without was executive dysfunction (51.2% vs. 38.7%, P = 0.04). According to multiple regression model, apractic-atactic gait disorder (odds ratio 2.82, 95% confidence interval 1.21-6.53), ADL functions (odds ratio 1.04, 95% confidence interval 1.01-1.08), and the Beck Depression Inventory (odds ratio 1.05, 95% confidence interval 1.02-1.09) related to SIVD. CONCLUSIONS: The most significant clinical features of MRI-defined SIVD were found to be apractic-atactic gait, impaired ADL functions, and depression.
