Acute Inflammatory Demyelinating Polyneuropathy
(AIDP, Guillain-Barré Syndrome, Acute Idiopathic Polyneuritis, Acute Inflammatory Polyneuropathy, Acute Autoimmune Neuropathy, Idiopathic Polyneuritis)
Acute inflammatory demyelinating polyneuropathy (AIDP) is a rare condition that causes the immune system to attack the nerves. There are treatments for this condition, so contact your doctor if you think you may have it.

AIDP is an autoimmune syndrome, but it is not clear what causes it. In this condition, the immune system begins to destroy the material that surrounds the nerves known as myelin, so the nerves can’t transmit signals efficiently. This causes muscles to lose their ability to respond to the brain’s messages.
One theory behind the cause is the presence of antibodies in the blood that may affect how the autoimmune system behaves. Antibodies are proteins that are made by the immune system to attack foreign substances that may threaten the body. But in the case of AIDP, there may be antibodies in the blood that might cause the attack of nerves.
Preceding infections with certain organisms may be involved in the cause of AIDP. These include infections with:
A risk factor is something that increases your chance of getting a disease or condition. If you have any of these risk factors, tell your doctor:
- Age: 15-35 and 60-75 years old
- Recent gastrointestinal or respiratory viral infection
If you experience any of these symptoms do not assume it is due to AIDP. These symptoms may be caused by other, less serious health conditions. If you experience any one of them, see your physician.
- Weakness or tingling in the legs that may spread to the arms and upper body

- Almost complete paralysis
