RT Journal Article SR Electronic T1 Neurocysticercosis presenting as bipolar disorder: a case report JF General Psychiatry JO Gen Psych FD BMJ Publishing Group Ltd SP e100663 DO 10.1136/gpsych-2021-100663 VO 34 IS 6 A1 Surbhi Batra A1 Sumit Kumar A1 Lokesh Singh Shekhawat YR 2021 UL http://gpsych.bmj.com/content/34/6/e100663.abstract AB Neurocysticercosis is the most common neuro-parasitosis caused by the larval stage of Taenia solium. The most common manifestations include seizures and hydrocephalus. Psychiatric abnormalities are relatively rare but depressive symptoms are frequent in patients with neurocysticercosis. However, mania as a presentation is relatively rare. Pregnancy and the postpartum period are relatively vulnerable times and they can lead to reactivation of existing neurocysterci lesions. We are discussing the case of a 23-year-old female patient with neurocysticercosis leading to the reactivation of lesions in the peripartum and postpartum period leading to bipolar affective disorder. Improvement in the patient was seen with a combination of antipsychotics, antihelmintics, antiepileptics and steroids, along with improved radiological signs of neurocysterci lesions. Although neurocysticercosis is a common illness, its prevalence presenting as a manic episode is merely 2.6% and, hence, missed easily. Therefore, it is important to rule out organic aetiology in patients even with a classic presentation of bipolar affective disorder and those having any other neurological symptoms and signs.
