atherosclerosis

[Obayan]

I have a really bad gene pool to dip into.  I have hypercholesterolemia, hypothyroidism, congestive heart disease with unstable angina, coronary artery disease, fibromyalgia, erythromelalgia, intracranial atherosclerotic disease, post traumatic stress disorder, chronic severe depression with suicidal tendencies, sleep apnea, diabeties, gerd and ibs.
Recently, I have been seeing shadows in my periferal vision.  Only on the right side.  I get dizzy when I close my eyes but just for a second before being ok again.  Then again, I get dizzy when I don't close my eyes as well.  Doc says it's because my heart isn't pumping enough blood to oxygenate the brain good enough.  I'm on more meds than I can count.  My question is, could the intracranial atherosclerotic disease be causing the problems with my vision?  On my mri it shows many little tiny white spots of scarring.  And my thought process has begun to have flaws such as memory loss.  I'm a 50 year old female.

It's already been determined that the lack of oxygen to the brain is what is causing me to pass out and get dizzy.  It's not that there isn't enough oxygen in the blood, it's that there isn't enough blood getting to the brain causing a series of mini strokes.  The question listed above was, I'm beginning to see shadown in my periferal vision on the right side.  I was wondering if this could be caused by the intracranial atherosclerosis.

It would be impossible to make a firm diagnosis based solely on the information you have provided.  I think depending on your blood pressure at the time of these symptoms, they might be caused by rapid change in blood pressure (similar to a "headrush" when standing up too quickly).  Intracranial vascular disease is also a possible contributor, but I don't think it is the primary cause.  

I therefore recommend checking blood pressure and discuss medication management with your doctors, in case the meds are causing your blood pressure to drop too low. Good Luck!
