Frontal lobe epilepsy.
Frontal lobe epilepsy accounts for only 10-20% of the patients in surgical series, but the incidence in non-surgical patient cohorts seems to be much higher. The typical clinical presentation of the seizures includes contralateral clonic movements, uni- or bilateral tonic motor activity as well as complex automatism. The yield of surface EEG may be limited due to the difficulty in detection of ...
full textFrontal lobe epilepsy.
About one-quarter of patients with refractory focal epilepsies have frontal lobe epilepsy (FLE). The typical seizure semiology for FLE includes unilateral clonic, tonic asymmetric or hypermotor seizures. Interictal electroencephalograms (EEG) usually reveal interictal epileptiform discharges and rhythmical midline theta, which has localizing value. The usefulness of ictal EEG recordings is limi...

The paroxysmal motor events during sleep are certainly common.The systematic use of nocturnal video-polysomnography has largely improved the diagnostic yield in patients with clusters of nocturnal motor events. Two broad nosological categories have been identified: parasomnias (sleep terror and sleep-walking), which are thought to represent disorders of arousal during sleep,and the epileptic se...

Temporal lobe epilepsy (TLE) is typically associated with long-term memory dysfunction. The frontal lobes support high-level cognition comprising executive skills and working memory that is vital for daily life functioning. Deficits in these functions have been increasingly reported in TLE. Evidence from both the neuropsychological and neuroimaging literature suggests both executive function an...
full textSurgery for frontal lobe epilepsy
Frontal lobe epilepsy makes up between 20 and 30% of all partial epilepsies and is the biggest subgroup of the extratemporal lobe epilepsies. Of the patients who undergo surgery for epilepsy up to 18% have a frontal lobe focus. The aetiology of frontal lobe epilepsy is varied, clinical semiology is diverse and seizures are often frequent, disabling and refractory to treatment. Imaging and EEG f...
full textSymptomatic nocturnal frontal lobe epilepsy
Nocturnal frontal lobe epilepsy (NFLE) is a disorder characterised by clusters of brief motor seizures during sleep, often without surface EEG epileptiform abnormalities’“. For these reasons, the prevalence of this disorder has probably been underestimated. Moreover, in the past, many patients with clusters of nocturnal motor attacks have been diagnosed as having nocturnal paroxysmal dystonia5,...
