Aman motor axonal neuropathy following dengue fever: A rare post-infectious neurological Sequeale in a young adult

Abstract

Guillain-Barré Syndrome (GBS) is a potentially life-threatening immune-mediated neuropathy that presents with ascending muscle weakness and areflexia. Among its subtypes, Acute Motor Axonal Neuropathy (AMAN) is characterized by pure motor involvement without sensory loss. While Campylobacter jejuni remains the classical antecedent infection, arboviral illnesses such as dengue are increasingly being implicated in triggering axonal variants of GBS. We present a rare case of AMAN in a 24-year-old male following recovery from dengue fever. Prompt administration of intravenous immunoglobulin (IVIG) led to significant neurological recovery. This case of 24 year old male highlights the importance of recognizing post-dengue neurological complications and initiating early immunotherapy to mitigate morbidity.
