CIDP (Chronic Inflammatory Demyelinating Polyneuropathy)

What is CIDP?

CIDP is an autoimmune disease that affects the peripheral nervous system. The peripheral nervous system is a network of nerves that connect the brain and spinal cord to the rest of the body. In CIDP, the immune system attacks the myelin sheath, which is a protective layer that surrounds the nerves. This damage to the myelin sheath can lead to a variety of symptoms, including weakness, numbness, and pain in the arms and legs.

What are the symptoms of CIDP?

The symptoms of CIDP can vary depending on which nerves are affected. Some of the most common symptoms include:

• Weakness in the arms and legs
• Numbness and tingling in the hands and feet
• Pain in the arms and legs
• Difficulty walking
• Fatigue
• Vision problems
• Hearing problems

What causes CIDP?

The exact cause of CIDP is unknown, but it is thought to be an autoimmune disease. This means that the immune system mistakenly attacks the body's own tissues. In CIDP, the immune system attacks the myelin sheath, which is the protective layer that surrounds the nerves. This damage to the myelin sheath can lead to a variety of symptoms, including weakness, numbness, and pain in the arms and legs.

How is CIDP diagnosed?

CIDP can be diagnosed with a variety of tests, including a physical examination, a nerve conduction study, and a blood test. A physical examination can help to identify the symptoms of CIDP, such as weakness, numbness, and pain in the arms and legs. A nerve conduction study can help to measure the electrical activity of the nerves. A blood test can help to identify the presence of antibodies that are associated with CIDP.

How is CIDP treated?

There is no cure for CIDP, but there are a variety of treatments that can help to relieve the symptoms. Some of the most common treatments include:

• Immunosuppressive drugs: These drugs can help to suppress the immune system and reduce the inflammation that is associated with CIDP.
• Plasmapheresis: This procedure involves removing the plasma from the blood and replacing it with a new plasma. Plasmapheresis can help to remove the antibodies that are associated with CIDP.
• Intravenous immunoglobulin (IVIG): This is a blood product that contains antibodies that can help to suppress the immune system and reduce the inflammation that is associated with CIDP.

What is the prognosis for CIDP?

The prognosis for CIDP varies depending on the severity of the disease. Some people with CIDP experience a complete recovery, while others may have long-term symptoms. The average life expectancy for people with CIDP is about 10 years.
