Abstract
Patients with vascular dementia (VaD) show cholinergic deficits that may result in characteristic clinical syndromes for different subtypes of the condition. Subcortical VaD is characterised by executive dysfunction and behavioural problems, reflecting deterioration of the frontal lobe. Based on limited open-labelled controlled studies of rivastigmine in VaD, this article aims to determine whether rivastigmine, a dual inhibitor of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), has any effects on the typical symptoms of subcortical VaD. Long-term rivastigmine treatment is safe and effective. Improvements in domains that characterise subcortical VaD were observed, indicating that rivastigmine may have provided targeted treatment in areas of the brain that are particularly affected in this patient population. A large, double-blind study of rivastigmine in patients with VaD is clearly warranted.
