Apraxia is a neurological
disorder characterized by the inability to perform learned (familiar) movements on command, even though the command is understood
and there is a willingness to perform the movement. Both the desire and the capacity to move are present but the person simply
cannot execute the act.
Patients with apraxia cannot use tools or perform such acts as tying shoelaces or button shirts
etc. The requirements of daily living are difficult to meet. Patients whose ability to speak is interrupted (aphasia) but
who are unaffected by apraxia are able to live a relatively normal life; those with significant apraxia are almost invariably
Apraxia comes in several different forms:
Limb-kinetic apraxia is the inability to make precise or exact
movements with a finger, an arm or a leg. An example is the inability to use a screwdriver notwithstanding that the person
affected understands what is to be done and has done it in the past.
Ideomotor apraxia is the inability to carry out
a command from the brain to mimic limb or head movements performed or suggested by others.
Conceptual apraxia is much
like ideomotor ataxia but infers a more profound malfunctioning in which the function of tools is no longer understood.
apraxia is the inability to create a plan for a specific movement.
Buccofacial apraxia, (sometimes called facial-oral
apraxia) is the inability to coordinate and carry out facial and lip movements such as whistling, winking, coughing etc on
command. This form includes verbal or speech developmental apraxia, perhaps the most common form of the disorder.
apraxia affects the person’s ability to draw or copy simple diagrams or to construct simple figures.
apraxia is a condition in which patients find it difficult to move their eyes.
Apraxia is believed to be caused by
a lesion in the neural pathways of the brain that contain the learned patterns of movement. It is often a symptom of neurological,
metabolic, or other disorders that can involve the brain.
