Definition: Difficulty performing motor activities, even though the person's movement, senses, and ability to comprehend what is being asked are still intact. Apraxia is basically a disconnect between the idea of a task and its execution.
Examples:
A person with Alzheimer's might be physically able to button a coat and see and feel the buttons on the coat, but there's a mental gap between the idea of buttoning the coat and actually being able to do it. Apraxia often affects the ability to do things like cooking, dressing, and grooming.
