1. Introduction Reflex seizures are seizures that are elicited by sensory or cognitive stimuli. These stimuli can be very diverse but are usually highly specific within one patient. The type of seizures that are induced by these stimuli can be tonic-clonic seizures, myoclonic jerks with or without absences, and absences with facial myoclonus. Focal seizures(More)
BACKGROUND Brain arteriovenous malformations (BAVMs) are thought to be sporadic developmental vascular lesions, but familial occurrence has been described. We compared the characteristics of patients with familial BAVMs with those of patients with sporadic BAVMs. METHODS We systematically reviewed the literature on patients with familial BAVMs. Three(More)
PURPOSE To determine clinical phenotypes, evolution and genetic background of a large family with a combination of two unusual forms of reflex epilepsies. METHOD Phenotyping was performed in eighteen family members (10 F, 8 M) including standardized EEG recordings with intermittent photic stimulation (IPS). Genetic analyses (linkage scans, Whole Exome(More)
We report a case of a girl who presented with typical absence seizures at age of 4.5 years. EEG showed absence seizures of sudden onset with 3 Hz spike-and-waves that also correlated with the clinical absences. The seizure semiology included subtle deviation of the eyes which prompted MRI investigation of the brain. This showed a periventricular nodular(More)
