Study Notes

Epilepsy Overview

Epilepsy often arises without a recognizable cause, frequently post brain damage, trauma, infections, tumors, or various neurologic diseases.

Types of Seizures

Atonic seizures are a specific type characterized by a sudden loss of muscle tone.
Partial seizures begin locally in the brain and often remain confined to one area.
Three types of partial seizures exist, illuminated by their localized seizure activities.

Antiepileptic Drug Mechanisms

Antiepileptic drugs (AEDs) operate primarily through three mechanisms:
- Enhancement of GABA action: Increases inhibitory neurotransmitter activities, helping to control seizures.
- Inhibition of sodium channel function: Reduces neuronal excitability, thereby stabilizing electrical activity in the brain.
- Rapid action is a significant advantage of certain medications, allowing for quick relief in seizure situations.

Special Considerations for Women

Certain AEDs exhibit a special role for women experiencing seizure exacerbations during menstrual cycles.
Tolerance to these medications may not develop due to the non-continuous administration in episodic use, making them particularly useful during these times.
