Neurocysticercosis (NCC) is the commonest parasitic disease of central nervous system and an endemic problem in India. Its clinical manifestations are varied, non specifi c and pleomorphic, depending on number and topography of lesions. We report two patients of NCC, who presented only with dementia. Dementia improved in both of them, by using steroids as cerebral decongestant. Since NCC mimic large number of neurological disorders, it is important that clinicians should be familiar with these rare presentations to avoid delay in diagnosis and management. This report further suggests the utility of decongestive therapy in multiple NCC. It also heralds that dementia can sometimes be a reversible syndrome, if diagnosis and its etiology is established early and correctly.
