Neurocysticercosis is a common parasitic infection in India presenting usually with seizues, headache, focal neurological deficits. Neurocysticercosis presenting as a psychiatric illness is rare. Disseminated cysticercosis with involvement of central nervous system and head and neck muscles is rare even in endemic areas. We present a case of disseminated cysticercosis, which presented with chronic tension type headache and affective mood disorder. Treatment with cysticidal drugs led to complete remission of psychiatric complaints. In endemic areas history suggestive of mood disorder should not be used as supportive evidence of a primary headache syndome like tension type headche without ruling out secondary causes. Making an early diagnosis can prevent morbidity.
