Parkinsonism

A clinical trial is currently underway to do just that — so that the history of post-encephalitic parkinsonism in the years following the Spanish Flu does not repeat itself.

In 1969, as chronicled in his book "Awakenings," the neurologist Oliver Sacks discovered that temporary remission of these chronic symptoms, coined post-encephalitic parkinsonism, could be achieved through the use of the Parkinson's drug L-DOPA.

And it eerily parallels other post-acute infection syndrome scenarios throughout history, including those potentially linked to epidemics of parkinsonism.

His wife, Wendy Stokes, said he had Parkinsonism and recently had a fall.

It caused parkinsonism, a side-effect of antipsychotics which affects muscles.
