Epilepsy is a chronic neurologic disorder characterized by recurrent seizures, brought on by excessive excitability of neurons in the brain. A seizure is divided into two broad categories: partial and generalized. Symptoms can range from brief periods of unconsciousness to violent convulsions. Epilepsy is initiated by synchronous, high-frequency discharge from a group of hyperexcitable neurons called a focus. A focus may result from several causes, including congenital defects, hypoxia at birth, head trauma, brain infection, stroke, cancer, and genetic disorders. The Anti-epileptic drugs can suppress mania and/or depression and stabilize mood in a patient with BPD. Drugs including, divalproes sodium, carbamazepine, and lamotrigine …show more content…

Neuropathic pain coming from damaged nerve or central nerve (stroke). Drugs such as gabapentin and pregabalin showed evidence that they work in long term nerve pain with diabetes and pain after shingles. However, only between 1 in 10 or 4 in 4 people will get this level of benefit, depending on the pain condition and the drug. Most people will get no pain relief. The antiepileptic drugs work in ways that can suppress discharge on neurons within a seizure focus and suppress propagation of seizure activity from the focus to other areas of the brain. But now it appears that all the AEDs act through five basic …show more content…

Suppression of Calcium influx: In the axon terminal influx of calcium through voltage-gated calcium channels promotes transmitter release; hence, drugs that block these calcium channels can suppress transmission. Several AEDs calcium channels can suppress transmission. Several AEDs including valproic acid and ethosuximide, act by this mechanism. 3. Promotion of potassium influx: Drug (ezogabine ) act on voltage-gates potassium channels to facilitate potassium influx. – underlie the drug’s ability to slow repetitive neuronal firing thereby provide seizure control
4. Antagonism of Glutamate: is the primary excitatory transmitter in the CNS. This work through two receptors’ NMDA receptors (N-menthel-D-aspartate receptors) and AMPA receptors (Apha_amino-3-hydroxy-5-methyl_4- isoxazole propionic acidrereceptors), - This action suppress neuronal excitation
5. Potentiation of GABA: AEDs potentiate the action of GABA, an inhibitory neurotransmitter that is widely distributed through the brain. by augmenting the action of GABA, these drugs decrease neuronal excitability, thus suppress seizure activity

The drugs produce side effects in most people, but there is a lack of evidence for most of the drugs in most types of neuropathic pain and fibromyalgia. Drugs such as lacosamide, lamotrigine, carbamazepam, clonazepam, phynytam have shown at least 50% pain intensity reduction over
