86 year old snoring faints

[Nancy2010]

My 86 year old mother just came back from the hospital where they did a lot of tests and nothing was diagnosed.  She is in good health, 99 lbs, 5'1 and walks daily with me.  Five weeks ago she fainted going out our door for an early walk.  My husband caught her before she fell and we noticed she was snoring and her eyes were open.  This week the same thing happened.   We were walking along about 3 blocks from home, and she said she felt fuzzy, and I was able to get her on the sidewalk before she hurt herself falling down.  She was snoring and her eyes were open and pupils pinpricks.

Yes, the EEG and MRI were both done.  They ruled out a lot.  
Thanks for your help and consideration.  We have an upcoming doctor appt. with a neurologist.

Best regards,

Hello.

Did the tests include EEG (electroencephalogram), which is done to diagnose or rule out seizures?

How was the MRI of the brain?

She seems fine afterwards.   A bit confused because she doesn't remember anything.

Hello.

What happens afterwards? Does she "wake up" feeling noramal? Any headache, memory loss, confusion?

The pinpoint pupils are a cause for concern.

Let me know.
