Doctor said that i have vertigo and migraine. i also sleep suddenly, hear people but cannot respond, afterwards i yawn, cannot speak. what could it be?

Tell your neurologis: To check your vitamin B12 ; vitamin d; combination of both can cause severe dizziness. It sounds like u have narcolepsy. Narcolepsy is like lack of sleep for the average person and it is a trigger that lowers one’s migraine threshold. 25% of narcoleptics get migraines. There are several meds that induce rem sleep. That will reduce yr migraines. Talk to yr neurologist.
