A new study revealed that Alzheimer’s disease can be avoided by adopting a healthy lifestyle, as reported by the Daily Mail.
Researchers performed neurological and neuropsychological tests and monitored the cognitive abilities of 1,700 participants every six months in the “90+ Study”, which started in 2003. Autopsies were conducted upon their death. It is one of the largest studies of its kind in the world.
Results showed that half of the dementia-free patients had the hallmark brain plaques, which led to memory loss and dementia when they died. On the other hand, half of the dementia patients developed symptoms of memory loss, even without having these build-ups in their brain.
Professor Claudia Kawas, lead author of the study, suggested that the reasons for such “cognitive resilience” in those who should have developed dementia but remained free of it was down to a healthy lifestyle.
Kawas told the delegates at the World Congress for Neurology in Kyoto, Japan that the group who had cognitive resilience exercised more and watched less television. She also noted that it was important to keep blood pressure under control.
However, she also pointed out that the findings are not yet decisive, and that the risk factors for Alzheimer’s disease need further research.
People should start to educate themselves and make the necessary lifestyle changes on how to build brain resilience and prevent the disease. Kawas said that from the scientific knowledge we have today, people should be suitably informed on what they can do about it.
The study suggested to keep the body and brain working in order to protect cognition. The study shed light on why some people get dementia and others do not, even if they reach a highly advanced age where the disease is more likely.
Kawas estimated that if these interventions were taken by more people, there would be two million fewer dementia cases in the United States by 2050.
According to the records of Alzheimer’s Disease International, there are about 46.8 million people living with dementia worldwide. This number is expected to almost double every 20 years — 75 million in 2030 and 131.5 million in 2050.
In America, about 5.5 million Americans of all ages have dementia as of 2017 — 5.3 million are aged 65 and older while approximately 200,000 individuals are under age 65 and have younger-onset Alzheimer’s.
