<b>Negative/Bad Effects of AED Drugs on EEG
</b><ul><ul><li>Diffuse Slowing</li><li>Electro-cerebral Inactivity</li><li>Epileptiform Discharges (this is rare)</li></ul>

</ul><b>
Drugs that cause this:
</b><ul><ul><li>Phenobarbital</li><li>Benzodiazepines</li><li>Carbamazepine</li><li>Phenytoin</li><li>Ethosuximide</li></ul>



</ul><b>
Positive/Good Effects of Drugs on EEG
</b><ul><ul><li>In epilepsy, reduction in generalized Spike and Wave (classic epileptiform EEG)</li><li>In epilepsy, decreased reactivity to photoparoxysms with photic stimulation</li></ul>

</ul><b>
Other Effects of AEDs:
</b><ul><ul><li>May reduce alpha frequency and voltage</li><li>Diffuse slowing and depressed levels of consciousness</li><li>Toxicity produces higher amplitude beta spindles</li><li>This includes anything that induces sleep, anything ending in “azepam” or “albetol”</li><li>Some types of anti-epileptic drugs for focal epileptiform discharges can cause seizures, agents that are gabaergic can induce absence or myoclonic epilepsy.</li></ul>
