In a prospective study, 283 children who presented with a first unprovoked seizure were followed for a mean of 30 months from the time of first seizure. Subsequent seizures were experienced by 101 children (36%). The cumulative risk of seizure recurrence for the entire study group was 26% at 12 months, 36% at 24 months, 40% at 36 months, and 42% at 48 months. The cumulative risk of recurrence i...

To provide evidence of whether seizure clustering is associated with drug resistance and increased mortality in childhood-onset epilepsy, a prospective, long-term population-based study was performed. One hundred and twenty patients who had been followed since disease onset (average age 37.0 years, SD 7.1, median 40.0, range 11-42; incident cases) were included. At the end of the follow-up peri...

Frontal lobe epilepsy (FLE) is considered the second most common type of the localization-related epilepsies of childhood. Still, the etiology of FLE in children, its impact on cognitive functioning and behavior, as well as the response to antiepileptic drug treatment in children has not been sufficiently studied. This review focuses on these aspects of FLE in childhood, and reveals that FLE in...

Photosensitivity is the most common mode of seizure precipitation. It is age-related, more frequent in females, and most often found in generalised epilepsies. Little is known about its relation to individual epileptic syndromes. This study on 1062 epileptic patients who had 4007 split screen video EEG investigations revealed that the relation to generalised epilepsy is even more close than gen...

Hemimegalencephaly (HME) is a rare disorder of cortical development with overgrowth of one cerebral hemisphere. Patients have intellectual delay, hemiparesis and severe epilepsy. Drug-resistant epilepsy is often treated with a hemispherectomy. We review the literature on HME natural history and report a 26-year-old man with HME who did not undergo hemispherectomy in childhood with recurrent foc...

Benign epilepsy with centrotemporal spikes (BECTS), also known as benign rolandic epilepsy (BRE) of childhood represents 15% of all childhood epilepsies [Handbook of Epilepsy Treatment (2000)]. A majority of these patients do no require treatment; however, in those cases where treatment is justified, the most efficacious medication with a benign safety profile should be selected. We present thr...

objective primary central nervous system lymphoma (pcnsl) is an extremely rare condition in childhood. we report the first case of pcnsl in a child in iran. clinical presentation a nine-year-old boy was referred to mofid hospital with the history of headache of four months and seizure of 2 months duration. magnetic resonance imaging of the brain revealed a hyper-intense lesion in left fronto-pa...
