The more risk factors for vascular disease one has in middle age, the higher the risk may be of developing Alzheimer’s disease in later life. This is the conclusion of a new study published in JAMA.

Vascular disease is defined as any condition that affects the circulatory system – the vessels that carry the blood to and from the heart.

Types of vascular disease include atherosclerosis, the hardening or narrowing of the arteries due to plaque buildup, and peripheral artery disease, the narrowing of the arteries in the limbs.

Obesity, high cholesterol, high blood pressure,diabetes, and smoking are some of the common risk factors for vascular disease.

Previous studies have suggested a link between vascular disease risk factors during midlife and increased risk of later-life dementia – particularlyAlzheimer’s disease, the most common form of dementia.
