Three patients with Gerstmann-Staussler-Scheinker disease (GSS) caused by a serine-for-phenylalanine substitution at codon 198 of the prion protein gene (PRNP) were compared to 9 age- and education-matched non-mutation-carriers from the same large Indiana kindred (GSS-IK) on a comprehensive neuropsychological test battery. Clinically significant impairments in intelligence, secondary memory, attention and cognitive processing speed, executive ability, and manual motor skills were noted in 2 patients. The wide range and the severity of the cognitive deficits indicated generalized cerebral dysfunction consistent with global dementia. One patient, symptomatic for less than 1 year, had more selective deficits involving memory, motor skills, and verbal fluency, suggesting early subcortical involvement.
