Neurocysticercosis, caused by the larval stage of the tapeworm Taenia solium, is the most common parasitic infection of the central nervous system and the single most common cause of seizures/epilepsy in developing countries. Neurocysticercosis is a pleomorphic disease whose manifestation varies with the number, size and topography of the lesion and the intensity of immune response of host to parasite. We are reporting three cases in which two cases presented with rapidly progressive dementia and third case with acute psychosis as the isolated manifestation of multiple neurocysticercosis. All cases reacted well to steroid and osmotic diuretics treatment. In this communication we highlight an uncommon neuropsychiatric presentation of neurocysticercosis and recognizing this reversible cause will avoid delay in treatment
