Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)
A chronic autoimmune disorder affecting peripheral nerves, causing progressive weakness and sensory loss
Quick Facts
- Type: Autoimmune Neuropathy
- ICD-10: G61.81
- Prevalence: 1-2 per 100,000
- Age: Can affect any age, peaks at 40-60
Overview
Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) is a rare autoimmune disorder that affects the peripheral nervous system - the network of nerves outside the brain and spinal cord. In CIDP, the body's immune system mistakenly attacks the myelin sheath, the protective coating around nerve fibers that enables rapid transmission of electrical signals. This demyelination process leads to progressive weakness, sensory loss, and functional impairment.
CIDP is considered the chronic counterpart to Guillain-Barré syndrome (GBS), but while GBS develops rapidly over days to weeks, CIDP progresses more slowly over months to years. The condition follows a relapsing-remitting or progressive course, with symptoms that can worsen, improve, and worsen again over time. Without proper treatment, CIDP can lead to significant disability, but with appropriate immunomodulatory therapy, many patients experience substantial improvement and can maintain good functional capacity.
The condition affects approximately 1-2 people per 100,000 in the general population, with a slight male predominance. While CIDP can occur at any age, it most commonly affects adults between 40-60 years old, though pediatric cases do occur. The exact cause remains unknown, but it is believed to involve a combination of genetic susceptibility and environmental triggers that lead to an aberrant immune response against peripheral nerve components.
CIDP is characterized by both motor and sensory involvement, typically affecting the limbs in a symmetric pattern. The proximal muscles (those closer to the trunk) are often more severely affected than distal muscles, which helps distinguish CIDP from other forms of peripheral neuropathy. Early recognition and treatment are crucial for preventing irreversible nerve damage and optimizing long-term outcomes.
Symptoms
CIDP symptoms develop gradually over at least two months, distinguishing it from acute conditions like Guillain-Barré syndrome. The presentation is typically symmetric, affecting both sides of the body, and can involve both motor and sensory functions. Symptoms may follow a progressive pattern or show periods of improvement and worsening.

Causes
CIDP is an autoimmune disorder where the body's immune system mistakenly attacks components of the peripheral nervous system. While the exact cause remains unknown, research has identified several factors that contribute to its development and progression.
Autoimmune Mechanisms
Immune System Dysfunction
The primary cause of CIDP involves aberrant immune responses:
- Molecular mimicry: Immune system confuses nerve proteins with foreign substances
- T-cell activation: Inflammatory T-cells attack nerve tissues
- Antibody production: Autoantibodies target nerve proteins
- Complement activation: Immune system proteins damage nerve structures
- Macrophage infiltration: Immune cells invade and damage nerve tissue
Target Antigens
Specific nerve proteins that may be targeted include:
- Myelin proteins: P0, P2, PMP22, connexin 32
- Paranodal proteins: Contactin-1, CASPR1, neurofascin
- Nodal proteins: Sodium channels, neurofascin-186
- Gangliosides: GM1, GD1a, GQ1b
Genetic Factors
- HLA associations: Certain HLA types may increase susceptibility
- Family clustering: Rare cases of familial CIDP
- Genetic polymorphisms: Variations in immune system genes
- Hereditary neuropathy overlap: Some cases overlap with genetic neuropathies
Environmental Triggers
Infections
Various infections may trigger CIDP in susceptible individuals:
- Viral infections: Epstein-Barr virus, cytomegalovirus, hepatitis
- Bacterial infections: Campylobacter jejuni, Mycoplasma
- COVID-19: Emerging association with SARS-CoV-2 infection
- Respiratory infections: Upper respiratory tract infections
Vaccinations
- Influenza vaccination (rare association)
- Hepatitis B vaccination
- COVID-19 vaccines (very rare reports)
- Generally, vaccination benefits outweigh risks
Associated Medical Conditions
Malignancies
- Hematologic cancers: Lymphomas, leukemias
- Solid tumors: Various carcinomas
- Paraneoplastic syndrome: Cancer-related immune dysfunction
- Treatment-related: Chemotherapy or radiation effects
Other Autoimmune Conditions
- Inflammatory bowel disease
- Systemic lupus erythematosus
- Rheumatoid arthritis
- Thyroid disorders
- Diabetes mellitus (type 1)
Pathophysiology
Demyelination Process
- Initial immune activation: Unknown trigger activates immune system
- Blood-nerve barrier breakdown: Allows immune cells to enter nerves
- Inflammatory infiltration: T-cells and macrophages enter nerve tissue
- Myelin destruction: Immune cells attack and destroy myelin sheath
- Conduction slowing: Damaged myelin impairs nerve signal transmission
- Axonal damage: Severe or prolonged inflammation damages nerve fibers
Regeneration and Repair
- Remyelination attempts: Schwann cells try to repair myelin
- Incomplete repair: New myelin often thinner and less efficient
- Chronic inflammation: Ongoing immune activity prevents full recovery
- Fibrosis: Scar tissue formation in chronic cases
Risk Factors for Disease Development
- Age: Middle-aged adults at higher risk
- Gender: Slight male predominance
- Genetic predisposition: Family history of autoimmune disease
- Previous infections: Recent viral or bacterial infections

Frequently Asked Questions
While both are inflammatory demyelinating polyneuropathies, the main difference is timing. Guillain-Barré syndrome (GBS) develops rapidly over days to weeks and typically improves spontaneously. CIDP progresses slowly over months to years and requires ongoing treatment. CIDP is essentially the chronic version of GBS.
CIDP is a chronic condition that cannot be cured, but it can be effectively managed with immunomodulatory treatments. Many patients experience significant improvement in strength and function with appropriate therapy. Some patients may achieve remission and be able to discontinue treatment, while others require long-term maintenance therapy.
Treatment response varies by individual and therapy type. IVIG may show effects within 2-6 weeks, while corticosteroids may take 4-12 weeks for maximum benefit. Some patients notice improvement within days, while others may take several months. It's important to be patient and work closely with your neurologist to optimize treatment.
With proper treatment, many people with CIDP maintain good functional capacity and quality of life. The degree of disability varies greatly among individuals. Early diagnosis and treatment are crucial for preventing irreversible nerve damage. Many patients continue working and maintain independent living with appropriate management.
CIDP is not typically hereditary. While there may be a genetic predisposition that increases susceptibility to autoimmune conditions, CIDP itself is not directly passed from parents to children. However, it's important to rule out hereditary neuropathies that can mimic CIDP, as they require different management approaches.
Yes, appropriate exercise is generally beneficial for people with CIDP. Physical therapy and gentle exercise can help maintain strength, improve balance, and prevent complications. However, it's important to avoid overexertion, which can worsen symptoms. Work with your healthcare team and a physical therapist to develop a safe exercise program.
Contact your neurologist promptly if you experience worsening weakness, new symptoms, or functional decline. This may indicate disease progression or the need for treatment adjustment. Don't wait for your next scheduled appointment if you notice significant changes, as early intervention can prevent further deterioration.
There are no specific dietary restrictions for CIDP itself. However, if you're taking corticosteroids, you may need to monitor sodium and sugar intake. Some patients find that anti-inflammatory diets help with overall wellness. If receiving IVIG, staying well-hydrated is important. Always discuss dietary concerns with your healthcare provider.
