Ideomotor apraxia: a study of initial severity

Abstract This study investigated whether there are predictors for initial severity of ideomotor apraxia (IMA) in focal left‐hemisphere vascular patients. One hundred and twenty‐nine subjects were examined between 15 and 30 days post‐onset. Twentyfive patients with bilateral lesions were also studied in order to delineate the role of the right hemisphere. Other neuropsychological variables (i.e., token test, progressive matrices and oral apraxia scores) and size of the lesion were included in the experimental design. The main results were that a) token test, progressive matrices, oral apraxia scores, and lesion size correlate significantly with IMA, and b) that the presence of a second lesion in the right hemisphere is not found to have any significant effect on initial severity of IMA.
