Rationale: Subacute sclerosing panencephalitis (SSPE) is a progressive neurological disorder caused by persistent measles virus infection. SSPE predominantly affects children and adolescents. The symptoms usually develop 6-15 years after measles infection and ultimately leading to death in many cases. Patient concerns: Patient 1 presented with cognitive decline and myoclonus and the Patient 2 presented with diminution of vision with myoclonic jerks. Diagnosis: Based on the clinical features with a characteristic electroencephalogram pattern and the presence of a high titer of anti-measles IgG in serum and cerebrospinal fluid, these patients were diagnosed as SSPE. Interventions: Antiepileptics were started for controlling myoclonus along with supportive treatment. Outcomes: Both patients were discharged on antiepileptics and supportive care. Lessons: Whenever there are unusual clinical manifestations with unknown vaccination status, SSPE can be suspected and the cerebrospinal fluid should be examined for anti-measles antibodies. Our case study also highlights the importance of universal coverage of measles vaccination. To reduce the incidence of measles and associated deaths, it is important to maintain a high level of immunization coverage for the measles vaccine and to strengthen all the integral components of the national immunization program.
