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 husband has the calcified stage, it is a healed stage and less likely to cause seizures. However the fact that he had a seizure after 7 years means that he should undergo certain tests to know the present condition. 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. Other conditions can also cause a seizure. Therefore it will first be important to do a CT scan or MRI scan brain and 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. Please do not worry.
