Brain death-like changes: A case report of anti-GQ1b antibody syndrome

Abstract

Rationale: Anti-GQ1b antibody syndrome originates in the peripheral nervous system or the central nervous system. Various overlapping syndromes and atypical manifestations are also seen in clinic. It is rare to see multiple sites (almost all targets) of central and peripheral damage at the same time, resulting in brain death-like changes in patient.Patient concerns: This is a 55-year-old female patient, with a history of prodromal upper respiratory tract infection, began with headache, quickly developed body paralysis, eye paralysis, disturbance of consciousness, apnea, and tested positive for anti-GQ1b antibody. The patient is diagnosed clearly, the disease progresses rapidly, and almost all GQ1b sites in the central nervous system and peripheral nervous system are involved, which is rare.
