Subacute sclerosing panencephalitis (SSPE) is a progressive neurological disorder with encephalitis that develops after measles infection and can be fatal. The incidence has decreased substantially after the initial use of measles vaccine in the 1960s. Patients generally present with various symptoms such as behavioral disturbances, myoclonic seizures, mental retardation and becoming withdrawn. Electroencephalography findings are characteristic at the early stage of the disease, but nonspecific at later stages. There is no curative medical treatment for SSPE but drugs such as immunomodulators and carbamazepine are being used to prevent progression. We present a patient with SSPE who was diagnosed and medicated for epilepsy for 3 years although she was suffering from behavioral disturbances, depression and myoclonic seizures. We recommend clinicians to consider SSPE as it can still be seen in our country despite the decreasing incidence of measles infection
