Abstract

Ideomotor apraxia (IMA) and ideational apraxia (IA) were studied in 32 Alzheimer's disease (AD) patients and in 30 non‐demented elderly controls using a standardized apraxia battery. AD patients performed significantly worse than controls on all apraxia tests, and were more impaired when pantomiming movements than when imitating movements. IMA and IA scores correlated with severity of dementia as measured by the Mini‐Mental State Examination. Analysis of individual performances revealed dissociated apraxic disorders in four patients, which may be interpreted as a manifestation of focal damage to left hemisphere cortical systems involved in praxis. Furthermore, these results suggest a greater ideational than ideomotor defect in apraxic AD patients.
