Reversible cerebral vasoconstriction syndrome associated with a traditional Japanese training method under a waterfall named Takigyo: a case report

摘要

CaseTakigyo is a traditional Japanese training method for psychosomatic conditions in which individuals meditate under a waterfall. A 55‐year‐old man presented with a mild headache and visual loss that occurred following Takigyo. On the day of admission, acute ischemic stroke was suspected based on brain magnetic resonance imaging examination. However, subsequent brain magnetic resonance imaging revealed reversible vasoconstriction of the cerebral diffuse segmental arteries.
