For the data collection, a structured questionnaire and the psychological tests Raven, Wisc-III and DAP III were applied, before and after the educational intervention. For the group comparison, the Mann Whitney test was used, and established significance level of 5%. RESULTS: It was found that previously infected children who received the educational intervention, children showed higher performance than the control group in strutured questionnaire (p<0.05). CONCLUSIONS: It is acceptable to suppose the positive influence and the importance in the use of educational interventions in the cognitive recovery and learning of children previously treated with anthelmintics.

Neurocysticercosis presenting with psychiatric manifestations

Cysticercosis is the most common helminthes infection of the human central nervous system[1]. Epilepsy is the most common presentation and occurs in 50-85% of patients. Psychiatric manifestations in a form of depressive disorders, cognitive decline and psychosis have been reported frequently[2]. A 19-year-old Nepalese male presented with severe headache, seizures, fears and anxiety for one week. ACT scan of the brain showed small calcified lesion in the right deep temporal white matter without perifocal edema. This was considered suggestive of a healed inflammatory granuloma-neurocysticercus cyst. Treatment with a combination of albendazol, dexamethazone, ranitidine, phenytoin, lorazepam and hydroxyzine resulted in a rapid recovery
