Aides to Bill Clinton last week vehemently denied speculation that the former president's intemperate remarks on the campaign trail were due to mild cognitive damage from his quadruple-bypass surgery in 2004.

Symptoms include short-term memory loss, slowed responses, trouble concentrating and emotional instability. In a landmark study published in the New England Journal of Medicine in 2001, researchers at Duke University Medical Center tested 261 patients before and after bypass surgery and found that 53% of them had significant cognitive decline when they were discharged — and 42% still suffered from it five years later.

More than half of heart bypass patients awoke with cognitive problems, ranging from a stroke to the inability to remember phone numbers, according to a 2001 study in the New England Journal of Medicine.

And then there is the condition known as "
bypass brain." That's where brain cells are killed due to the lack of oxygen to the brain during a critical part of the surgery.
