Nodding Syndrome Cases had higher rates than Community Controls of prior measles infection and moldy food before onset
High Case-onset months aggregated across years corresponded to periods of low crop production and food shortages
Peaks of epidemic Nodding Syndrome (2003-08) followed an epidemic of measles (1998–2002)
NS has clinical features comparable to post-measles subacute sclerosing panencephalitis (SSPE)
Onchocerciasis is likely a NS bystander, causally unrelated to the neurological disease
