Cholinergic deficits might contribute to vascular cognitive impairment. Trials of cholinesterase inhibitors in patients with vascular dementia are difficult because of heterogeneous disease mechanisms and overlap between vascular and Alzheimer's disease (AD) pathology in the age-group recruited. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is a genetic form of subcortical ischaemic vascular dementia. It represents a homogeneous disease process, and because of CADASIL's early onset, comorbid AD pathology is rare. We did a multicentre, 18-week, placebo-controlled, double-blind, randomised parallel-group trial to determine whether the cholinesterase inhibitor donepezil improves cognition in patients with CADASIL.
