Definition[edit | edit source]

Apraxia is a motor disorder caused by damage to the brain (specifically the posterior parietal cortex or corpus callosum.[1] Apraxia is inability to carry out learned purposeful movement despite the presence of a good motor, sensory, or coordination function. Both the desire and the capacity to move are present but the person simply cannot execute the act.

Relevant Anatomy[edit | edit source]

Causes[edit | edit source]

Apraxia has a neurologic cause that localizes fairly well to the left inferior parietal lobule, the frontal lobes (especially the premotor cortex, supplementary motor area, and convexity), or the corpus callosum. Any disease of these areas can cause apraxia, although stroke and dementia are the most common causes. Interestingly, callosal apraxia is rare after callosotomy and is much more common with anterior cerebral artery strokes or tumors
