Infectious polyneuritis is a nerve disorder that causes inflammation of multiple nerves in the body. This condition is also referred to as Guillian-Barre Syndrome and is characterized by weakness, numbness and tingling sensations in the legs and feet. It can be a serious and potentially life-threatening condition and requires immediate medical attention. Some synonyms for Infectious polyneuritis include Acute Inflammatory Demyelinating Polyneuropathy (AIDP), Landry's Paralysis, Ascending Paralysis, and Acute Idiopathic Polyneuritis. Regardless of the term used, all describe the same condition, and early diagnosis is crucial in preventing further complications. Treatment typically involves supportive care and intravenous immunoglobulin therapy.
