Autosomal dominant partial epilepsy with auditory features (ADPEAF) is a rare form of epilepsy, a condition that is characterized by recurrent seizures. In ADPEAF, specifically, most affected people experience secondary generalized seizures and partial seizures, some of which are associated with sound-related symptoms (such as buzzing, humming, or ringing) and/or receptive aphasia (inability to understand written or spoken words). Less commonly, seizures may cause visual hallucinations, a disturbance in the sense of smell, vertigo, or other symptoms affecting the senses. Signs and symptoms of the condition generally begin in adolescence or early adulthood. ADPEAF is caused by changes (mutations) in the LGI1 or RELN gene and is inherited in an autosomal dominant manner. The seizures associated with ADPEAF are typically well controlled with medications that are used to treat epilepsy (called antiepileptic drugs).
