To characterize the clinical, behavioral, and neuropsychological features of dementia resulting from ischemic infarcts within the paramedian mesencephalic and diencephalic regions.
Evaluated clinical neurological, behavioral, and cognitive features in a cohort of 6 patients with paramedian thalamic, subthalamic, and mesencephalic infarcts.
Identified and correlated structural lesion locations with specific neuropsychological deficits using computed tomography and magnetic resonance imaging.
All 6 patients exhibited initial arousal deficits that gradually recovered to normal wakefulness, followed by persistent impairments in attention, mental control, psychomotor speed, and severe anterograde and retrograde amnesia.
Prominent behavioral changes included apathy, lack of motivation, and flat or labile affect, which persisted chronically in 5 of 6 patients while resolving in 1 patient with an isolated mesencephalic lesion.

Implication

Case series uncovers a characteristic subcortical dementia syndrome after midbrain and thalamic strokes, highlighting clinicoanatomic overlap with subcortical degenerative disorders.
