The Neurobiology Of Antiepileptic Drugs For The Treatment Of Nonepileptic Conditions, Michael A. Rogawski, Wolfgang Löscher

Michael A. Rogawski

Antiepileptic drugs (AEDs) are commonly prescribed for nonepileptic conditions, including migraine headache, chronicneuropathic pain, mood disorders, schizophrenia and various neuromuscular syndromes. In many of these conditions, as in epilepsy, the drugs act by modifying the excitability of nerve (or muscle) through effects on voltage-gated sodium and calciumchannels or by promoting inhibition mediated by γ-aminobutyric acid (GABA) A receptors. In neuropathic pain, chronic nerveinjury is associated with the redistribution and altered subunit compositions of sodium and calcium channels that predisposeneurons in sensory pathways to fire spontaneously or at inappropriately high frequencies, often from ectopic sites. AEDs maycounteract this abnormal activity by …

Antiepileptic drugs (AEDs) provide satisfactory control of seizures for most patients with epilepsy. The drugs have the remarkable ability to protect against seizures while permitting normal functioning of the nervous system. AEDs act on diverse molecular targets to selectively modify the excitability of neurons so that seizure-related firing is blocked without disturbing non-epileptic activity. This occurs largely through effects on voltage-gated sodium and calcium channels, or by promoting inhibition mediated by GABA-A (γ-aminobutyric acid, type A) receptors. The subtle biophysical modifications inchannel behaviour that are induced by AEDs are often functionally opposite to defects in channel properties that are caused …
