Cerebral small vessel disease (SVD) is a common accompaniment of ageing. Features seen on neuroimaging include recent small subcortical infarcts, lacunes, white matter hyperintensities, perivascular spaces, microbleeds, and brain atrophy. SVD can present as a stroke or cognitive decline, or can have few or no symptoms. SVD frequently coexists with(More)
RATIONALE Delirium is often unrecognized in ICU patients and associated with poor outcome. Screening for ICU delirium is recommended by several medical organizations to improve early diagnosis and treatment. The Confusion Assessment Method for the ICU (CAM-ICU) has high sensitivity and specificity for delirium when administered by research nurses. However,(More)
Cigarette smoking doubles the risk of dementia and Alzheimer's disease. Various pathophysiological pathways have been proposed to cause such a cognitive decline, but the exact mechanisms remain unclear. Smoking may affect the microstructural integrity of cerebral white matter. Diffusion tensor imaging is known to be sensitive for microstructural changes in(More)
BACKGROUND AND PURPOSE Cerebral white matter lesions (WMLs) are frequently found on magnetic resonance imaging scans in both cognitively intact and demented elderly persons. Vascular risk factors, especially hypertension, are related to their presence. However, not every person with vascular risk factors has WMLs, which suggests interaction with other(More)
Gait disturbances are common in the elderly. Cerebral small vessel disease, including white matter lesions and lacunars infarcts, is thought to disrupt white matter tracts that connect important motor regions, hence resulting in gait disturbances. Pathological studies have demonstrated abnormalities in white matter that may appear normal on brain imaging.(More)
Vascular factors play a role in the etiology of Alzheimer's disease (AD), presumably due to emergence of white matter lesions. However, important white matter structures involved in the etiology of AD, including the corpus callosum (CC), remain invariably free from macroscopical white matter lesions, although loss of microstructural integrity assessed with(More)
OBJECTIVE Long-term data on recurrent vascular events after young stroke are limited. Our objective was to examine the long-term risk of recurrent vascular events after young stroke. METHODS We prospectively included 724 consecutive patients with a first-ever transient ischemic attack (TIA), ischemic stroke, or intracerebral hemorrhage (ICH), aged 18 to(More)
BACKGROUND AND PURPOSE Stroke in young adults has a dramatic effect on life; therefore, we investigated the long-term functional outcome after transient ischemic attack, ischemic stroke, or intracerebral hemorrhage in adults aged 18 to 50 years. METHODS We studied 722 young patients with first-ever stroke admitted between January 1, 1980, and November 1,(More)
BACKGROUND Little is known about the incidence and risk of seizures after stroke in young adults. Especially in the young seizures might dramatically influence prognosis and quality of life. We therefore investigated the long-term incidence and risk of post-stroke epilepsy in young adults with a transient ischemic attack (TIA), ischemic stroke (IS) or(More)
