The EEGs of 13,560 patients have been reviewed in order to determine whether abnormal findings, epileptiform or not, have a hemispheric dominance. We have included outpatients and hospitalized patients as well. Eight hundred and thirty-five EEGs had generalized abnormal findings, and 414 EEGs had lateralized abnormal findings. The EEGs of 322 patients (77.7%) had a left predominance, and those ...
Patients with complex nocturnal behaviors (parasomnia, sleepwalking) can sometimes be difficult to distinguish from those with epilepsy.The differential diagnosis includes identifying abnormalities on electroencephalography (EEG) that are specific for epilepsy epileptiform discharges. Although these are rarely seen in individuals without epilepsy, and unknown to be associated with sleep disorde...
Recurrent epileptiform activity occurs spontaneously in cultured CNS neurons and in brain slices in which GABA inhibition has been blocked. We demonstrate here that pharmacological treatments resulting in either the block of glutamine production by astrocytes or the inhibition of glutamine uptake by neurons suppress or markedly decrease the frequency of spontaneous epileptiform discharges both ...
In vivo and in vitro evidence from animals suggesting that gap junctions (GJs) play a role in the spreading of epileptiform activity. We have examined the influence of the gap junction opener trimethylamine (TMA) and the connexin 36 (Cx36) gap junctional blocker, quinine, on epileptiform activity induced by 4-aminopyridine (4-AP) in the rat entorhinal cortex (EC) and the CA1 hippocampal region....
