Leber's Hereditary Optic Neuropathy with Mitochondrial DNA 11778 Mutation Presenting with Various Types of Seizures

Leber's hereditary optic neuropathy (LHON) is a mitochondrial genetic disease characterized by acute or subacute visual loss associated with other neurologic diseases. We report a man with LHON caused by a mitochondrial DNA point mutation at nucleotide position 11778, who presented various types of seizures, and hydrocephalus. EEG showed frequent brief generalized 2.5~3 Hz spike or polyspikes-and-wave activities. Brain MRI and cisternography showed communicating hydrocephalus. LHON plus associated with epilepsy and hydrocephalus in our patient widens the clinical presentation of LHON. J Korean Neurol Assoc 24(5):498-502, 2006
