PURPOSE: Although seizures are the most common presentation of neurocysticercosis (NCC), the electroclinical characteristics of the seizures have not been adequately studied.
MATERIALS AND METHODS: The study cohort included 308 consecutive patients presenting with a new-onset seizure, both acute symptomatic or unprovoked. They were divided into two groups: Group 1 (NCC group), those in whom imaging studies revealed active or inactive NCC (N = 184 (59.7%)) and group 2 (non-NCC group), those in whom either imaging was normal or revealed abnormalities other than NCC or the diagnosis was idiopathic generalized epilepsy (N = 124 (40.3%)).
RESULTS: Clinical features significantly associated with group 1 included focal seizures (specifically, aphasic seizures (P < 0.05)), seizure clusters (P < 0.0001), postictal Todd's paresis (P < 0.05), and peri-ictal headaches (P < 0.008). In addition, somatosensory and visual seizures, and focal-clonic and focal-tonic were more frequent in this group. Generalized clonic seizures (P < 0.05) were significantly more common in the group 2. The findings of regional epileptiform abnormalities (P = 0.0001) and primary generalized epilepsy (P < 0.0001) on electroencephalography were significantly more common in group 2.
SIGNIFICANCE: In patients presenting with new-onset seizure, aphasic seizures, seizure clusters, postictal Todd's palsy and peri-ictal headaches might augur the finding of NCC, both active and inactive lesions, on imaging.
