Abstract

An 11-month-old girl presented to us with recurrent episodes of hemiplegia affecting either side of the body, which were associated with febrile illnesses. Extensive workup in efforts to rule out other causes including vascular, metabolic or neuromuscular causes were unremarkable. Clinical diagnosis of alternating hemiplegia of childhood (AHC) was made and was later confirmed with genetic analysis. This report aims to enlighten clinicians on the complex presentation of AHC and to highlight that epileptic seizure, although a different disease entity, may be common in the presentation of AHC.
