Visceral crisis is a cerebral (uncontrolled) disease that belongs to the group of crises with an acute onset and occurs with impaired coordination of movements, fever, anxiety and loss of consciousness. The disease is very similar to encephalitis, cerebromyellitis, and subdural tumor. The disease occurs due to blockage or rupture of a cerebral vessel. Cerebral crises are, as a rule, isolated, only occasionally repeating in the form of paroxysms. Visceral crises begin suddenly and can be mild or severe, affecting the upper or lower extremities.
