Hi, Thanks for writing in. Neuricysticercosis is infection of the brain by the dog tape worm. This occurs due to contamination of food and water. The neurocysticercus is an organism that occurs in 4 stages and the cystic stage is the one that causes most seizures. Since your has has the calcified stage, it is a healed stage and less likely to cause seizures. However the fact that he had a seizure since 6 years means that the granuloma might be causing sudden outbursts of electrical activity. Seizures happen due to sudden out bursts of electrical activity in the brain and that can happen due to the old calcified granuloma or any new granuloma. Since CT scan is already done then proceed with an electroencephalogram to study the focus of abnormal electrical activity in his brain. Once the tests are done, he can be treated with anti epileptic medications for months and also he might need a dose of anti helminthic should there be any active neurocysticercosis lesion. If there is brain swelling then measures are to be taken to reduce it. He must avoid driving, swimming, cooking over fire and working with heavy machinery requiring high degree of alertness till his doctor allows him. Also make a note of any seizure attacks he gets in the next few days. This might happen and must be told to the doctor to give proper dose of medicine. If it is fully calcified then the infection is inactive. Repeat scan might be required to know recent activity. A single granuloma can be cured and might take months to years. If no seizure for 5 years then it is understood to be cored. He can eat non veg that is cooked properly in pressure cooker. Please do not worry.
