A member asked:
Other than epilepsy explain repeated polyspike and wave discharges as well as alpha and theta slow wave activity. also persistent cortical instability?
A doctor has provided 1 answer
Too much to list: For an awake person, the rhythm should be alpha. Slowing in a specific area, polyspikes and cortical instability all indicate irregular discharges, which are consistent with the cortex being the source of epilepsy. The cortex makes an electrical charge, the disorganized and irregular discharges can be the cause of a seizure.
