Although risk factors for first stroke have been identified, the predictors of long-term stroke recurrence are less well understood. We performed the present study to determine whether dementia diagnosed three months after stroke onset is an independent risk factor for long-term stroke recurrence. ⋯ Our results suggest that dementia significantly increases the risk of long-term stroke recurrence, with additional independent contributions by cardiac disease and sex. Cognitive impairment may be a surrogate marker for multiple vascular risk factors and larger infarct volume that may serve to increase the risk of recurrence. Alternatively, less aggressive medical management of stroke patients with cognitive impairment or noncompliance of such patients with medical therapy may be bases for an increased rate of stroke recurrence.

Case Reports
A case of spinal cord decompression sickness presenting as partial Brown-Sequard syndrome.
Type II decompression sickness (DCS) usually manifests as myelopathy; however, there are no reports of Brown-Sequard syndrome in association with diving accidents. We report a 35-year-old man who developed type II DCS presenting as partial Brown-Sequard syndrome. MRI of the thoracic spine revealed two punctate foci of increased signal intensity in the right T6 spinal cord.
