Quick Answer
CIDP is a chronic autoimmune neuropathy — causing progressive weakness and numbness. Treatable with immunotherapy.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a chronic autoimmune disorder affecting peripheral nerves — causing progressive weakness and numbness. Unlike Guillain-Barre (acute), CIDP is chronic and relapsing. It's treatable with immunotherapy.
What is CIDP
Autoimmune: immune system attacks peripheral nerve myelin — demyelination. Chronic: progressive over >8 weeks — chronic course. Polyneuropathy: affects multiple nerves — symmetric weakness/numbness. Relapsing: may relapse and remit — chronic condition. Distinct from GBS: GBS is acute, CIDP is chronic — different prognosis. Treatable: immunotherapy effective — good prognosis with treatment.
Recognizing CIDP
Progressive weakness: gradual weakness over weeks-months — legs then arms. Numbness: sensory loss — stocking-glove distribution. Gait problems: difficulty walking — weakness and sensory loss. Reflexes: reduced or absent reflexes — demyelination. Progression: symptoms worsen over time — chronic course. Relapses: may improve then worsen — relapsing course.
Diagnosis of CIDP
Clinical criteria: progressive weakness/numbness >8 weeks — chronic course. Nerve conduction studies: demyelinating pattern — slowed conduction, conduction block. Lumbar puncture: elevated protein — supports diagnosis. MRI: nerve root enhancement — may show nerve involvement. Exclude mimics: rule out other neuropathies — hereditary, diabetic, toxic. Response to treatment: improvement with immunotherapy — supports diagnosis.
Treatment of CIDP
First-line: IVIG (intravenous immunoglobulin) — effective, well-tolerated. Corticosteroids: prednisone — effective but side effects. Plasma exchange: plasmapheresis — alternative treatment. Maintenance: long-term treatment — chronic condition. Relapse management: adjust treatment — individualized. Rehabilitation: physical therapy — maintain function. Monitoring: regular follow-up — assess response, adjust treatment.
When CIDP needs specialist care
If you have progressive weakness/numbness, suspected CIDP, or neuropathy not responding to treatment — see a neurologist. CIDP requires specialist diagnosis and treatment.

When to seek professional evaluation
CIDP is discussed at neurology/emg evaluation — because proper diagnosis and treatment require specialist care.

There is no cure, but most patients recover significantly with immunotherapy and rehabilitation. Recovery may take weeks to months, and the degree of recovery varies.
GBS following vaccination is rare (approximately 1–2 per million doses for influenza vaccine, for example). The risk from the infection itself is generally higher than from the vaccine.
Migraine is a neurological condition; headache is one feature. Associated symptoms and functional impact are important for diagnosis.
Aura refers to visual, sensory, or speech symptoms that precede the headache in some people. Both types are migraine; the presence of aura may influence management discussion.
