Brachial plexopathy
Alternate Names : Neuropathy - brachial plexus, Brachial plexus dysfunction, Parsonage Turner syndrome
Definition
Brachial plexopathy is pain, decreased movement, or decreased sensation in the arm and shoulder due to a nerve problem.
Overview, Causes, & Risk Factors
Brachial plexus dysfunction (brachial plexopathy) is a form of peripheral neuropathy. It occurs when there is damage to the brachial plexus, an area where a nerve bundle from the spinal cord splits into the individual arm nerves. Damage to the brachial plexus is usually related to direct injury to the nerve, stretching injuries, pressure from tumors in the area, or damage that results from radiation therapy.
Brachial plexus dysfunction may also be associated with: - Birth defects that put pressure on the neck area
- Exposure to toxins, chemicals, or drugs
- Inflammatory conditions, such as those due to a virus or immune system problem
In some cases, no cause can be identified.
