Selective cognitive impairment during focal and generalized epileptiform EEG activity.
It is well established that generalized epileptiform EEG discharges unaccompanied by overt clinical change may nevertheless be associated with transitory cognitive impairment (TCI) detectable by appropriate psychological testing. However, the tests employed in most research studies of this phenomenon are of little use for routine clinical application. They are suitable for administration only o...
متن کاملReading performance in children with rolandic epilepsy correlates with nocturnal epileptiform activity, but not with epileptiform activity while awake.
OBJECTIVE An association between language impairment and rolandic epilepsy is frequently reported. This impairment could be correlated with the amount of nocturnal epileptiform activity. METHODS We retrospectively analyzed 26 children with rolandic epilepsy and/or rolandic spikes. All had undergone a 24-hour EEG and neuropsychological assessment within 2 weeks. Reading performance (reading wo...
متن کاملEpileptiform activity in children with developmental dysphasia: quantification of discharges in overnight sleep video-EEG.
We present results of analysis of overnight sleep video-EEG in 8 patients with developmental dysphasia and rolandic discharges. We evaluated the incidence of epileptiform discharges (expressed as paroxysmal activity density) at one or more electrodes in different sleep stages in three different periods of the night (after falling asleep, around midnight and before awakening). The difference of ...
متن کامل[Developmental dysphasia and epileptiform EEG activity in children].
Objective. To study the electrical activity of the brain in children with developmental dysphasia (alalia). Material and methods. We analyzed the EEGs of 65 children with developmental dysphasia, including 48 boys and 17 girls, aged from 3 to 4 years 11 months. General speech underdevelopment (GSU) of the 1st level (with active vocabulary less than 15-20 words) was found in 31 children and GSU ...
متن کاملSlow-wave activity arising from the same area as epileptiform activity in the EEG of paediatric patients with focal epilepsy.
OBJECTIVE The aim of this study was to investigate the presence and characteristics of apparent non-epileptiform activity arising in the same brain area as epileptiform activity in the EEG of paediatric patients with focal epilepsy. METHODS The EEG from eight patients was analysed by an automated method which detects epochs with a single underlying source having a dipolar potential distributi...
