Is fasting obligatory for an epileptic person who loses consciousness for short periods?

Fasting is obligatory for someone who experiences fainting spells in Ramadan, and it does not waive the obligation. If one loses consciousness for a few hours, they must still fast, as this does not negate theotyping of fasting. However, if the fainting spell lasts the entire day, from dawn to sunset, their fast is invalid, and they must make up that day. If they regain consciousness during the day, their fast is valid.
