Abstract Focal seizures are episodes of pathological brain activity that appear to arise from a localised area of the brain. At present, the understanding of the pathophysiology of epilepsy does not allow for specific choice of AEDs based on the assumed pathophysiology of the epilepsy, and a “corresponding” presumed mechanism of action of the AED.

Epilepsy is a collection of diverse disorders that together affect approximately 1% of the general population. Clipping is a handy way to collect important slides you want to go back to later. Seizures are caused by paroxysmal discharges from groups of neurons, which arise as a result of excessive excitation or loss of inhibition. Current therapies are largely symptomatic and are aimed at controlling seizures in affected individuals. Do you have PowerPoint slides to share?
