What is apraxia?

Apraxia is defined as the inability to perform previously learned tasks or movements despite having the desire and the physical capability to carry them out. This neurological disorder often results from damage to areas of the brain responsible for planning and executing motor functions, particularly affecting the coordination needed for purposeful activities involving movement. Individuals with apraxia may understand the commands or the gestures required but cannot execute them effectively.

This condition can manifest in various forms, such as ideomotor apraxia, where a person cannot imitate gestures or perform actions on command, and ideational apraxia, which involves difficulties in completing a sequence of actions or using objects correctly. Understanding apraxia is crucial in managing patients, especially in the context of rehabilitation after brain injury or strokes, where the ability to perform daily activities significantly impacts quality of life.

The other options describe different neurological deficits or disorders: the inability to perceive sensory stimuli relates to agnosia, the inability to recognize faces pertains to prosopagnosia, and the inability to communicate verbally is characteristic of aphasia. Each of these conditions has distinct causes and implications that differentiate them from apraxia.
