Like it’s being discussed on another recent thread:  http://www.moyamoya.com/cgi-bin/yabb2/YaBB.pl?num=1232716391 it could possibly be a type of seizure. There are a wide variety of possible symptoms of seizures, depending on what parts of the brain are involved, and seizures after successful surgery seems to be a common thing with MMD. As I explained on another post, my neice had a similar incident a year or so after surgery. I think a MM patients' brain is extremely sensitive.

I would have tests done to be safe. If it was a seizure, hopefully medications or an adjustment of seizure medications can help her.

Hi Shirley,

Blackouts can occur from a number of different causes. It's possible your daughter's spells are unrelated to moyamoya.

As an example, my brother experienced such spells, and in his case, the spells were related to a particular drug he was taking for something other than moyamoya.

I also noticed  my brother having similar symptoms when his blood pressure got too low. I'm not suggesting these are the reasons your daughter is experieincing blackouts. Knowing your daughter has moyamoya, and has had two bypass surgeries, I would not ignore the spells. I would suggest your daughter see her doctor sooner than later to uncover the cause of her blackouts.

Keep us posted.
