In this review, we discuss chronic inflammatory demyelinating polyneuropathy (CIDP), which is a disease with proximal and distal weakness and sensory disturbances resulting in impaired daily activity. The diagnosis is based on the clinical presentation and electrophysiology demonstrating demyelination in the peripheral nerves. CIDP can be successfully treated with immunoglobulin, glucocorticoids or plasma exchange, and during the latest decade, immunoglobulin has been administered subcutaneously improving patients' flexibility and autonomy. By time, 30% of the patients will remit, and maintenance treatment will no longer be necessary.
