Abstract

Subacute sclerosing panencephalitis (SSPE) is a rare progressive neuroinfectious disease due to a late complication of the measles virus. The hallmark clinical features of this disease include behavioral changes, myoclonus, dementia, visual disturbances, and pyramidal and extrapyramidal signs. The presence of characteristic high-amplitude periodic complexes on electroencephalography and raised antibody titers against measles in the cerebrospinal fluid help solidify the diagnosis. We present a case of a 40-year-old patient with SSPE who initially developed ophthalmologic manifestations 30 years after the primary measles infection. This case highlights both typical and atypical features of SSPE and provides a diagnostic framework for evaluating cases that fall outside of the standard scope of this disease.
