Dr. Celia Greenlaw discusses the potential neurologic complications of measles virus, including acute measles encephalitis and subacute sclerosis panencephalitis (SSPE). Although rare, SSPE is a devastating fatal disease that occurs years after measles infection and typically impacts children infected with measles at a young age. Tips include prevention of acute and late neurologic complications of measles via vaccination and high levels of herd immunity, as well as an early signs & symptoms approach to recognition for front-line providers in child neurology.
