Parasites that can enter the brain include tapeworms, schistosomes, etc. They can be treated by general treatment, medication, and surgery if necessary. 1. Tapeworms: After infection with tapeworms, rest should be paid attention to, and anthelmintic drugs such as praziquantel, albendazole, mebendazole, etc. If brain cysticercus is present, it can be treated by using surgery to remove cysticercus tissues from the relevant tissues and so on. 2. Schistosoma: if high fever and other symptoms appear, it can be treated by cooling down the temperature, replenishing fluids, etc., and using drugs such as praziquantel to kill the worms. Schistosoma parasitize the brain tissues, and head CT shows that the lesions are mainly located in the parietal lobe and occipital lobe, and there are multiple high-density nodules on one side. There is cerebral edema around the lesion, and even the lateral ventricles are compressed and deformed, and surgical removal of the lesion is an option. If there are parasites in the head, you should seek medical treatment promptly.
