Sympathetic Apraxia Symptoms

What are the Sympathetic Apraxia Symptoms?

The exclusive symptom of Sympathetic Apraxia is the paralysis of the right hand

This paralysis can be either as 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.

Apraxia is characterised by the below

  • loss of the ability to do certain learned movements, such as talk, walk, or understand tasks.

Praxic functions are frequently altered following brain lesion, giving rise to apraxia – a complex pattern of impairments that is difficult to assess or interpret.

Apraxia should be studied in consideration with and could contribute to other fields such as normal motor control, neuroimaging and neurophysiology.

What causes Apraxia?

Here are the causes of Apraxia

  • Damage to the Brain
  • Decrease in brain function which is called as degeneration of the brain, especially in areas of the brain that help to coordinate movements.

In patients with left hemispheric stroke, apraxia has been reported to be prevalent in approximately one-third of this population.

In clinical practice, it is not uncommon that more than one type of apraxia is present in a single affected patient

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.

Which condition is commonly associated with sympathetic apraxia?

Sympathetic apraxia is commonly associated with the below disorders

  • Right hemiparesis as well as
  • Broca’s aphasia

Where is the lesion underlying Sympathetic Apraxia? 

Sympathetic apraxia thought to be consequent upon frontal lobe lesions.
