Nodding syndrome proved to be a tauopathy
Nodding syndrome (NS) is a neurologic disorder of unknown cause that affects children in the subsistence-farming communities of East Africa. Researchers have proposed causes for NS that include malnutrition, parasites, and viruses, but have not proved a clear link to any of them. NS is characterized by stereotypical head dropping movements, cognitive impairment, impaired growth, and seizures. The age of onset is usually 5–15 years of age. NS has been documented in the Republic of South Sudan and Tanzania; also it is a major health problem in the villages of northern Uganda.
