Confusional Migraine

I just found out that my aunt confusional migraine. she does not remember who she is or who I am or someone else. It is a very hard time for me because it's my best friend. how i should act around her? What should I tell him? and can you back her memory, to what extent and how long?
Thank you

The confusion is permeated with inattention, distractibility, and difficulty with speech and motor activities, and can last from 10 minutes to 20 hours, usually ending in deep sleep. The best thing you can do is give him some time to come to his senses, stay with it to ensure it goes well.
This type of migraine is characterized by episodes of short-term amnesia (memory loss), confusion, agitation, lethargy, and dysphasia (difficulty speaking) caused by minor head injury.
The only thing you can do is be with him.
