Isolated neurological symptoms of Wilson’s disease manifesting as focal epileptic seizures without hepatic involvement: Insights from a case report

Patients with Wilson's disease, an autosomal recessive disorder caused by <i>ATP7B</i> mutations, present with hepatic and neurological symptoms, including tremors, chorea, personality changes, and rare manifestations such as neuropathy, autonomic dysfunction, headache, and epilepsy. This report describes the case of a 14-year-old man born to consanguineous parents who presented with focal seizures and oromandibular dystonia. A neurological exam revealed left upper limb hypotonia. An electroencephalogram showed right hemisphere epileptiform activity, and magnetic resonance imaging indicated bilateral basal ganglia hyperintensities. An ophthalmological exam revealed an incomplete Kayser-Fleischer ring. Laboratory tests confirmed Wilson's disease with low serum ceruloplasmin (3 mg/dL) and elevated urinary copper excretion (1226 mcg/24 h) levels. Treatment included penicillamine (250 mg/day) and zinc (50 mg bi-daily), along with clonazepam for seizures. Routine follow-ups were recommended. This case highlights the importance of recognizing neurological presentations in patients with Wilson's disease for timely diagnosis and management.
