Objectives:

The objective was to compare the long-term clinical, radiological, and cognitive outcomes in children with single-lesion neurocysticercosis who received 7 or 28 days of albendazole therapy.

Methodology:

This observational study conducted over 1 year included (1) consecutive children with single-lesion neurocysticercosis who received 7 or 28 days of albendazole therapy in the acute state and (2) completed follow-up for at least 5 years. Seizure recurrence, resolution of lesions, cognition (Malin’s Intelligence Scale for Indian Children), behavior, and school performance (National Initiative for Children Healthcare Quality Vanderbilt Assessment Scale) were assessed.

Results:

Group A (albendazole for 7 days) comprised 55 children, and group B (albendazole for 28 days) included 48 children. The mean age at the time of diagnosis of neurocysticercosis was 6.6 ± 1.8 years; the mean age at the time of assessment for the study was 13.2 ± 1.2 years. Focal-onset seizures were the most common clinical presentation (58.3%). The majority of lesions were ring-shaped (92.3%) or colloidal (58.2%), with perilesional edema (89.3%). In the long-term follow-up, radiological resolution of the lesions was comparable in both groups. Complete resolution was seen in 52.7% receiving 7 days and 54.2% receiving 28 days albendazole. Seizures recurred in 20% receiving 7 days and 20.8% receiving 28 days albendazole. Overall, a low intelligence quotient (IQ < 70) was seen in 55.3% cases, “somewhat problematic” school performance in 12%, and behavioral abnormalities were present in 20% of the cases. The results were comparable between the 2 groups.

Conclusion:

Seizure control, radiological resolution of lesion, school performance, cognitive and behavioral outcomes in the long term are comparable in children with single-lesion neurocysticercosis who have received albendazole cysticidal therapy for 7 days and 28 days. Recurrence of seizure is seen with both regimens in the long term, necessitating regular follow-up and discussion regarding the risk of recurrence before a withdrawal of anticonvulsant therapy.
