Abstract

Cognitive deficits in Parkinson's disease (PD) include disturbances in working memory. We examined sequential visuo-spatial memory span by means of an adaptation of the Corsi Block-Tapping Task in groups of medicated (n=14) and non-medicated (n=15) patients with early stage PD, and in control subjects (n=22). A deficit in memory span was found in medicated patients with early stage PD relative to controls. There were no differences between non-medicated patients relative to either controls or medicated patients. A decrease in sequential visuo-spatial memory span appears to be a relatively early feature of PD and most likely reflects executive rather than mnemonic dysfunction. © 2003 Elsevier Ltd.
