Charcot at the Salpêtrière: ambulatory automatisms

Jean-Martin Charcot, as professor of neurology at the Salpêtrière Hospital in Paris, delivered a series of dialogue case presentations on general neurology in 1887-1889. These cases, never before translated into English, provide a first-hand view of Charcot's renowned teaching method and his opinions on many neurologic topics. One patient with bizarre ambulatory spells probably representing absence status was recognized by Charcot as an epileptic. This otherwise healthy young man, without a history of generalized epilepsy or hysteria, experienced multiple spells during which he suddenly became unaware of his surroundings, rambled throughout Paris and its outskirts, and had complex interactions with other people. As Charcot unraveled the diagnostic mystery, he traced the patient's wanderings and analyzed the differential diagnosis, treatment, and pathophysiology of these intermittent spells.
