why does atrial fibrillation cause strokes?

Clot formation: Because blood in the left atrium is not propelled forward normally during atiral fibrillation, it allows for the formation of clots. Small areas of blood pooling resembling little eddy currents allow blood to slow down and form clots. If one of these clots is then propelled forward it can travel to the brain, become lodged in a blood vessel and cause a stroke.A clot the size of a pinhead can do it.
Dr. John Garner

Standstill: The extremely rapid rates of atrial fibrillation are in fact so fast that they create two problems: the top chamber is not mechanically moving very far at all, so it cannot shake clots loose, in the overactive atrial tissue secretes chemicals which increase the likelihood of clot formation. These processes come together to substantially increase stroke risk.

Depends: New onset atrial fibrillation is often self limited, going away by itself. But the cause dictates the subsequent course. Thus treating things like high blood pressure, heart valve disease, heart failure, over active thyroid hormones, coronary disease, and avoiding alcohol may be important. Some drugs are useful to maintain rate and rhythm. If needed, electric shock (cardioversion) is effective.

Sometimes: There is a gene that makes the tendency to get it more likely, but most a fib is due to environmental and aquired factors such as age, valvular heart disease and alcohol.
