متن کاملNeuropathological assessment of the lesions of significance in vascular dementia.
OBJECTIVES To better define the neuropathology of vascular dementia. METHODS The neuropathological findings in 18 elderly, undemented subjects free of cerebrovascular disease were compared with 19 elderly undemented subjects who had cerebrovascular disease (many of whom had had a "stroke") and 24 elderly demented subjects who had cerebrovascular disease, but no other pathology to account for ...

متن کاملAnterior-medial thalamic lesions in dementia: frequent, and volume dependently associated with sudden cognitive decline.
BACKGROUND The anterior-medial thalamus (AMT), which is associated with memory processing, is severely affected by Alzheimer's disease pathology and, when damaged, can be the sole cause of dementia. OBJECTIVE To assess the frequency of magnetic resonance imaging (MRI) hyperintensities affecting the AMT, and their relationship with sudden cognitive decline. METHODS 205 consecutive participan...
