Arab medicine: Avicenna (980 - 1037): Canon medicinae (The Canon of Medicine)
"Epilepsy is a disease which prevents those organs affected from using the senses, moving and walking upright. [...]
And this is caused by a blockage. Usually it is a general seizure, caused by some damage, which affects the front cerebral ventricle; and it is impossible for the person affected to remain standing upright. "
Correct statement:
Epileptic seizures originate in the brain and often lead to loss of upright posture (falling) and "impairment of the senses" (e.g. twilight states or unconsciousness).
Incorrect statement:
Epileptic seizures are caused "mechanically" by a blockage and are localised in the front cerebral ventricle. (Correct: Epileptic seizures are the result of a stimulation disturbance in the cerebral nerve cells.)
