Sympathetic Apraxia Symptoms

Sympathetic Apraxia Symptoms

What is sympathetic apraxia?

Sympathetic apraxia is the inability of the non pathologic hand to carry out commanded movements.

Sympathetic apraxia is an ideomotor apraxia of the left hand.

This condition is commonly associated with a right hemiparesis as well as a Broca’s aphasia.

What are the Sympathetic Apraxia Symptoms?

Sympathetic Apraxia Symptoms include the below

  • partial paralysis of the right hand
  • sometimes right hand might be fully paralysed

What causes Sympathetic Apraxia?

It is caused by left frontal lesions disconnecting the left inferior parietal lobe from the right premotor cortex so that “praxicons” for the left hand cannot reach the hand area of the right frontal lobe. 

This condition is the apraxia of the left limb due to damage to the anterior left hemisphere.

This condition is most commonly associated with expressive aphasia.

Where is the lesion underlying Sympathetic Apraxia? 

Sympathetic apraxia thought to be consequent upon frontal lobe lesions.
