Transcortical Apraxia Definition


Transcortical Apraxia: A form of APRAXIA characterized by an acquired inability to carry out a complex motor activity despite the ability to mentally formulate the action. This condition has been attributed to a disruption of connections between the dominant parietal cortex and supplementary and premotor cortical regions in both hemispheres. (From Adams et al., Principles of Neurology, 6th ed, p57)

Synonym: limb kinetic apraxia, ideomotor apraxia, ideokinetic apraxia, classic apraxia, ideomotor dyspraxia.
