It can be frightening when your child has a febrile seizure, and the few minutes it lasts can seem like an eternity. As our understanding of the underlying pathophysiology improves, we are better able to describe the neuroanatomical diagnosis, select the best medication for an individual patient and predict the potential for pharmacoresistance to antiepileptic drugs (AEDs). How memories are constructed. re-entrant loops versus coupled oscillators. The onset patterns of focal seizure activity have been studied intensively, and they have largely been distinguished into two types—low amplitude fast oscillations (LAF), or high amplitude spikes (HAS).

Winner of the Standing Ovation Award for “Best PowerPoint Templates” from Presentations Magazine. A complex network of neurons that transmit nerve impulses and signals is evident in the brain. A seizure occurs when a portion of the brain becomes overly excited or when nerves in the brain begin to fire together in an abnormal fashion. A wide range of activity-dependent phenomena may be perturbed, including cell division and migration sequential expression of receptors formation and strengthening of synapses.

Febrile seizures occur in young children at a time in their development when the seizure threshold is low. However, one commonality across epilepsies is a disrupted balance between excitatory (via glutamatergic signaling) and inhibitory (via GABAergic signaling) drive at the synaptic level that can result in seizure activity.
