Alien Hand Syndrome ! ! ! (AHS)

It is a very rare and interesting neurological disorder. I don’t know whether you would love to read about it, but I really love to write about it. So, lets go to the topic. The affected individual would have full sensation of his hands , but their hand would not be in their control. Moreover, they won’t feel their hand as a part of their body.

Their hand will have it’s own mind, as it will work on it’s own, the owner do not have any ownership or control over it. As you know our brain is responsible for voluntary and involuntary actions.

AHS is very dangerous and life risking, as the afflicted hand may even kill the afflicted individual itself. A new study says that neural activity is restricted to the primary motor cortex during the unconscious motor activity seen with AHS.

It is caused due to certain brain injury like stroke, trauma etc., it can also be a side effect of a brain surgery , of patients having two lobes of brain separated to relieve severe epilepsy. Or it can also be caused due to a damage of corpus callosum.

There is no treatment for AHS. But it can be prevented by placing some objects in the afflicted hand to keep the afflicted hand busy.
