The vagus nerve and epilepsy


Hi. The vagus nerve is the longest and most complex of 12 pair of cranial nerves that emanate from the brain. It transmit information to or from the surface of the brain to tissues and organs elsewhere in the body.

The name vagus comes from the Latin term for "wandering." This is because the vagus nerve wanders from the brain into organs in the neck,chest, and abdomen.

It also know as the 10th cranial nerve or cranial nerve X.

The vagus nerve has two bunches of sensory nerve cell bodies, and it connects the brainstem to the body. It allows the brain to monitor and receive information about several of the body's different functions.

There are multiple nervous system function provided by the vagus nerve and its related parts. The vagus nerve contribute to the automatic nervous system, which consist of the parasympathetic and sympathetic parts. The nerve is responsible for certain sensory activities and motor information for movement within the body.

VAGUS NERVE STIMULATION

Stimulation of the vagus nerve is a medical procedure that is used to try to treat a variety of conditions. It can be done either manually or through electrical pulses.

The effectiveness of vagus nerve stimulation has been tested through clinical trials.Consequently the United State Food and Drug Administration has aproved its use to threat two different conditions.

Epilepsy

This involves a small, electrical device, similar to pacemaker, being placed in a person's chest. A thin wire known as a lead runs from the device to the vagus nerve. The devise is placed in the body by surgery under general anesthetic. It then sends electrical impulse at regular intervals, throughout the day, to the brain via the vagus nerve to reduce the severity or even stop, seizures.

Mental illness

In 2005 the FDA approved the use of vagus nerve stimulation as a treatment for depression. It has also been found to help with the following conditions:

. Bipolar disorder
. Anxiety disorders
. Alzheimer' disease

In my next blog I will write about other vagus nerve effects.
