The inability to execute a voluntary motor movement despite being able to demonstrate normal muscle function. Apraxia is not related to a lack of understanding or to any kind of physical paralysis; rather, it is caused by a problem in the cortex of the brain.

1877, medical Latin, from German apraxie (H. Steinthal, 1871), from Greek apraxia "inaction," from privative prefix a- (see a- (3)) + praxis "a doing, action, business" (see praxis [..]

refers to the loss or absence of the ability to perform learned purposeful movements, for example, dressing oneself or driving a car, despite not experiencing any motor deficits. The condition is beli [..]

Apraxia is a neurological condition in which a person has trouble making specific movements. There is no damage with the muscles themselves - the problem is in the brain. In extreme cases of apraxia t [..]

An impairment in the ability to begin and execute skilled voluntary movements, even though there is no muscle paralysis. See also ideational apraxia and ideomotor apraxia.

(n) inability to make purposeful movements

Inability to carry out a complex or skilled movement; not due to paralysis, sensory changes, or deficiencies in understanding. [Click Here to Return to List]

Inability to assemble, build, draw, or copy accurately; not due to apraxia of single movements. [Click Here to Return to List]

Deficit in the execution of a movement due to inability to access the instructions to muscles stored by previous motor experience. [Click Here to Return to List]

A brain disorder in which a person cannot perform certain actions, such as combing hair, picking up a pencil, or speaking, even though they want to and have the physical ability to do so.

The loss of the ability to perform tasks that require remembering patterns or sequences of movements (like waving goodbye).

Difficulty controlling voluntary muscular movements, usually without motor impairment, which impacts speech.

<clinical sign> <neurology> Inability to execute a skilled or learned motor act, not related to paralysis or lack of comprehension, caused by a cortical lesion. (27 Sep 1997)
