Stroke survivors with an irregular heart rhythm called atrial fibrillation (AF) are at a heightened risk of developing dementia, the degenerative condition which is characterized by a progressive deterioration in cognitive function, claims a new study.
According to researchers, the threat of dementia is two times higher in stroke patients with irregular heart beat than those with normal heart rhythms.
Atrial fibrillation describes an irregular and often rapid heart rhythm which results from abnormal electrical impulses in the heart.
The heart condition affects millions and becomes more common as people age. About 15 percent of strokes occur in people with AF.
