Benefits of rivastigmine on attention in dementia associated with Parkinson disease

Abstract

In a 24-week, randomized, double-blind, placebo-controlled, multicenter study of rivastigmine, 487 patients with dementia associated with Parkinson disease underwent assessment of attention on the Cognitive Drug Research computerized cognitive assessment system before dosing and 16 and 24 weeks later. Significant benefits of rivastigmine over placebo were seen on all aspects of attention assessed: sustained attention, focused attention, consistence of responding, and central processing speed.
