Headaches More Common among Epilepsy Sufferers with Neurocysticercosis than Other Structural Brain Lesions.

Neurocysticercosis is a leading cause of seizures and epilepsy in the developing world. Cysticercosis is endemic in many regions of Central and South America, sub-Saharan Africa, India, and Asia. Neurocysticercosis is of emerging importance because globalization has increased travel between Hawai'i and disease-endemic areas. Headache and epilepsy are two of the most common complications of neurocysticercosis infection. Currently, it is not known if epilepsy patients with neurocysticercosis are more likely to have headaches than those with other structural brain lesions or those with no structural brain abnormalities. This study was designed to investigate whether epilepsy patients with neurocysticercosis report co-morbid headaches more frequently than those with other or with no structural brain lesions. A retrospective cross-sectional study of all patients treated at a community based neurology clinic for epilepsy during a three-month period was performed. One-hundred sixty patients were included in the analytical study. Co-morbid headaches were more commonly present among those with neurocysticercosis (40%) than those with other structural lesions and those with no structural brain abnormalities (19% and 22%, respectively; P = .031). Headache frequency among those reporting co-morbid headaches did not differ significantly between the groups. Prevalence of co-morbid headaches is greater among epilepsy patients with neurocysticercosis than those with other structural brain lesions or no structural brain abnormality. Epilepsy patients with neurocysticercosis may be especially vulnerable to development of headaches and a thorough headache history should be obtained to help screen for affected individuals.
