Can you tell me if seizures are common in people with aotic stenosis, and heart failure?  My father, aged 89, has aortic stenosis, and, I suspect (heart failure although this has never been talked about )and over the past 6 months has become increasngly frail and "disabled" - shortness of breath swollen legs and feet, very confused, eats very little, limited ability to weight bear.    He lives in another country so I am not fully aware of his condition.  It appears that he has just had a seizure.  Is this typical inpeople with heart failure?  Thanks,
IN SEVERE AORTIC STENOSIS THERE IS LOW EJECTION OF BLOOD FROM HEART TO BRAIN SO THERE IS SYNCOPAL ATTACK AND IF THIS SYNCOPE LAST LONGER THERE IS CEREBRAL HYPOXIA WHICH CAN LEADS TO SEIZURE.IN CASE OF HEART FAILURE ASSOCIATED WITH THIS AORTIC STENOSIS THERE IS FURTHER DECREASE OF BLOOD SUPPLY TO BRAIN AND PRECIPITATION OF SEIZURE....
