AbstractGuillain-Barré Syndrome (GBS) is a rare but potentially life-threatening neurological disorder characterized by acute onset ascending paralysis and sensory abnormalities. This article provides a comprehensive overview of GBS, covering its epidemiology, etiology, clinical presentation, diagnostic evaluation, management and treatment, prognosis, psychosocial impact, recent advances in research, public health implications, and ethical considerations. Epidemiological data reveal variations in GBS prevalence, incidence rates, and geographical distribution influenced by climate, infectious disease prevalence, and genetic susceptibility. Etiological factors include preceding infections, vaccinations, and autoimmune mechanisms, although the precise pathophysiology remains incomplete. Clinical presentation encompasses prodromal symptoms, motor deficits, sensory abnormalities, autonomic dysfunction, and variants such as Miller-Fisher Syndrome and Bickerstaff brainstem encephalitis. Neurological examination findings include weakness, paralysis, sensory deficits, and reflex changes, while autonomic dysfunction manifests as cardiovascular, respiratory, and gastrointestinal symptoms. Diagnostic evaluation relies on clinical criteria, laboratory tests (e.g., cerebrospinal fluid analysis, nerve conduction studies), and consideration of differential diagnoses. Management strategies encompass supportive care, immunomodulatory therapies (e.g., intravenous immunoglobulin, plasma exchange), and rehabilitation interventions to optimize functional outcomes and promote recovery. Prognosis varies depending on clinical features, treatment response, and complications such as respiratory failure and autonomic instability. Psychosocial impact encompasses psychological effects on patients and caregivers, highlighting the importance of coping strategies and support systems. Recent advances in research focus on emerging treatments, genetic predisposition, and biomarker discovery, offering promise for improving GBS outcomes. Public health implications include vaccination safety concerns and healthcare system considerations for GBS management. Ethical considerations encompass patient autonomy, resource allocation, and end-of-life decision-making.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
