Mystery Uncovered, Heart Might Be The Culprit That Kills The Brain of Alzheimer's Disease Patients

Heart is the culprit that kill the brain of the patients with Alzheimer’s disease, say the researchers of Whodunnit in a study published in the Journal of Alzheimer’s Disease. The heart powering up with 35 million beats a year destroys the brain, say the researchers. They also added that the brain. thought to be the dependent of the heart. turns out to be a victim of its beat.

Alzheimer’s disease is the most common form of dementia often seen in elderly people characterised by memory loss and other mental functionalities. The researcher says that the dementia is uncongenial, it doesn’t appear to provide simple treatment options and counter intuitive because the brain thought to be the dependent of the heart turns out to be a victim of its beat.

The study suggests that Alzheimer’s disease begins in the cardiovascular system as a result of decades of continues activity, leading to stiffening of the walls of great arteries. The stiffening restricts the elasticity from cushioning the impact of the pulse on the small blood vessels of the brain. Each beat causes trauma on the brain resulting in silent bleeding, gradual functionality impairments like consciousness, memory, awareness and personality, said the study, reports the Sydney Morning Herald.

University of Sydney neurobiologist Jonathan Stone, the lead author, said that it would be pessimistic to think that it would have been better if Alzheimer’s disease was caused by a virus and could be treated with a vaccine. He also added on the optimistic side that, there are evidences to prove that exercises increase the stability of the heart and help in keeping it resistant to damage. He also suggested that people in their 80s who don’t want to lose their cognitive functions should start cardiovascular exercises right away.

About 40,000 individuals aged between 50 and 80 are to be involved by Stone in the clinical trial to prove this theory. The cardiovascular risk thought to be marginal one before about 10 years is now being considered as major risk factor which is one we can do something about, said Ian Hickie, Brain and Mind Institute executive director, the one who supports that Alzheimer’s is a vascular disease.
