BACKGROUND AND PURPOSE Vascular dementia is a common cause of dementia, and cerebrovascular disease is related to a higher risk of dementia. The frequency of dementia associated with ischemic stroke and the effects of different definitions of dementia in the diagnosis are still incompletely known. We evaluated the frequency of cognitive decline and dementia(More)
BACKGROUND Depression affects up to 40% of patients with ischemic stroke. The relationship between site and size of brain infarcts and poststroke depression is still not well characterized. Further possible contribution and interaction of white matter lesions and brain atrophy has not been studied previously. We conducted a magnetic resonance image-based(More)
Seventy patients with one brain infarct on magnetic resonance imaging (MRI) were studied 3 months after ischemic stroke by a standardized protocol to detail side, site, type, and extent of the brain infarct, as well as severity of white matter lesions and brain atrophy. Depression was diagnosed by DSM-III-R and DSM-IV criteria. The brain infarcts that(More)
This is the first study that focuses on insomnia in stroke patients. A subgroup of 277 patients from a consecutive series of 486 stroke patients aged 55-85 years was subjected to a comprehensive psychiatric evaluation 3-4 months after ischemic stroke. Of 277 patients, 56.7% reported any insomnia complaint and 37.5% fulfilled the DSM-IV criteria of insomnia.(More)
BACKGROUND Poststroke global cognitive decline and dementia have been related to poor long-term survival. Whether deficits in specific cognitive domains are associated with long-term survival in patients with ischaemic stroke is not known in detail. METHODS Patients with acute stroke subjected to comprehensive neuropsychological evaluation were included(More)
BACKGROUND AND PURPOSE Frequency of poststroke dementia is high, and stroke considerably increases the risk of dementia. The risk factors for dementia related to stroke are still incompletely understood. We sought to examine clinical determinants of poststroke dementia in a large well-defined stroke cohort. METHODS The study group comprised 337 of 486(More)
BACKGROUND AND PURPOSE This study compared stroke features and poststroke disability in two age groups of patients with ischemic stroke: younger (55 to 70 years) and older (71 to 85 years). Stroke has an impact on daily living in many areas, but whether risk factors, stroke features, and poststroke disability differ between young and old patients with(More)
Patients with stroke may have an increased risk of suicide. We sought to examine the frequency and clinical correlates of suicidal ideas 3 and 15 months after stroke. The study group comprised 286 of 486 consecutive patients aged 55-85 years who at 3 and 15 months after ischemic stroke completed a detailed medical, neurological and radiological stroke(More)
BACKGROUND AND OBJECTIVE The main objective of our study was to detail the frequency and clinical determinants of poststroke generalized anxiety disorders in a large, well-defined stroke cohort. METHODS A total of 277 stroke patients aged 55-85 were subjected to a comprehensive psychiatric evaluation between 3 and 4 months after ischemic stroke. Primary(More)
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(More)
