Home / Neuro / Apraxia


The best way to describe apraxia is to first discuss praxis… which is the complex neurological system that remembers previously learned movements in our brains so that our movements are smooth and efficient.  It also remembers how to use objects.  That way we don’t have to plan how to move each time we perform a very common movement or use a very common object.  Praxis is how we remember movements.  The absence of praxis is apraxia.

Someone with apraxia may understand the task of sitting down, but cannot automatically execute it.

Someone with apraxia may know that a fork is something you eat with, but cannot initiate or carryout the actual task.

Apraxia is common in Alzheimer’s disease and with traumatic damage to the left hemisphere of the brain or the corpus callosum.
