Judo as a possible cause of anoxic brain damage. A case report

J Sports Med Phys Fitness. 1991 Dec;31(4):627-8.


The rules of judo provide for strangulation techniques in which the blood supply to the brain is blocked by pressure on the carotid arteries; such techniques produce anoxia and possible unconsciousness if the victim fails to submit. A case is presented of a patient with signs of anoxic brain damage, with psychometric investigation showing memory disturbance consistent with a left temporal lobe lesion. This patient had been frequently strangled during his career as a judo player; it is suggested that such frequent strangulation was the cause of the damage. Such an observation indicates the need for caution in the use of such techniques.
