The disease is mainly caused by the ingestion of uncooked pork and beef carrying cysticerci or the eggs. The adults of tapeworms are parasitized inside the small intestine of the human body. They absorb food essence, disturb the functional activities of qi and impair the spleen and stomach, giving rise to the dysfunction of the spleen and stomach in transportation and transformation. When bladder worms move about and are parasitized in subcutaneous tissue, cerebral cortex, cerebellum or basis encephali, etc., they may block collaterals.

In this case, blood stasis and phlegm will form. Blood stasis and phlegm intermingle and stagnate. If the state appears under the skin, tubercular phlegm pit will occur; if it appears in cerebral cortex, epilepsy will occur; if it appears in cerebellum or the fourth ventricle of cerebellum, dystaxia will occur; if it appears in basis encephali, pathological change of pyramidal tract, etc. will occur.
