Seizures are brief episodes of excessive or abnormal neural activity in the brain.  The outward symptoms can vary from mild loss of awareness to full-body physical thrashing.

If you have had a seizure, your treating doctor must report this to the state, and the state can remove your driving privileges.  Once you have had a seizure, you must be seizure-free, with or without medication, for a minimum of 6 months in order to have your license restored.

The state can make exceptions for a single seizure caused by an infection, illness, toxic ingestion or metabolic imbalance in someone who has otherwise been seizure-free for at least 6 months.

Another exception is made for a pattern of strictly nocturnal seizures, or ones that only happen immediately after waking.  This history must date back at least two years.

Additionally, if your seizures are consistently preceded by an aura of a predictable duration for a minimum of two years, you may be eligible for a waiver allowing you to regain your license.
