The study investigated performance on pantomime and imitation of transitive and intransitive gestures in 80 stroke patients, 42 with left (LHD) and 38 with right (RHD) hemisphere damage. Patients were also categorized in two groups based on the time that has elapsed between their stroke and the apraxia assessment: acute-subacute (n = 42) and…

The present study was designed to investigate the relationship between performance of limb gestures and the severity of Alzheimer's disease (AD). Apraxia tends to occur at later stages of AD, and the severity of apraxia has been shown to vary with the severity of AD dementia. Participants were 19 mild (including 9 with no cognitive impairment and…
