Mar 5, 2026
A pair of strange medical mysteries explores a 1916–1920 sleeping sickness, its baffling symptoms, and the autopsy findings that pointed to brain inflammation. The story touches on a famed neurologist's use of L-DOPA to briefly revive chronic patients and how the outbreak shaped dopamine research. The episode also dives into the brutal, secretive Barkley Marathons and its near-impossible course.

Episode notes
Encephalitis Lethargica Linked To Basal Ganglia Damage
- Encephalitis lethargica (EL) caused profound sleepiness, ocular disturbances, and Parkinsonian symptoms across 1916–1927.
- Konstantin von Economo linked EL to basal ganglia inflammation, explaining movement and behavioral deficits observed worldwide.
Mysterious Disappearance Of The Epidemic
- EL cases abruptly declined by the mid-1920s, disappearing from wards by 1927 without a definitive cause.
- Possible explanations include herd immunity or viral mutation, but no singular answer was reached.
Oliver Sacks' Dramatic Levodopa Awakenings
- Oliver Sacks used levodopa on chronic EL patients and produced striking, near-instant awakenings from years-long catatonia.
- The treatment restored movement, speech, and emotion temporarily, later chronicled in Awakenings and a film adaptation.
