Coronary artery bypass surgery
Coronary artery bypass surgery (CABG) offers a new lease on life for thousands of people each year. But it has also been blamed for “brain fog,” a loss of memory and thinking skills that follows the procedure in some people. Such brain problems are often called “cognitive impairment.” But the operation itself may not be to blame, according to a review in today’s Annals of Internal Medicine. A team of mostly Veteran’s Affairs researchers concluded that intermediate and long-term cognitive impairment after cardiovascular procedures “may be uncommon.” That said, they recommend that anyone thinking about open-heart surgery or other large cardiovascular procedure should discuss with the surgeon the possibility of cognitive impairment.
