What do you think of this study that suggests that Alzheimer’s’s disease has a lot to do with lifestyle and some consider it “diabetes 3”?

Alzheimer’s disease, which is the leading cause of dementia, is generated by insulin resistance and insulin-like growth factor dysfunction that happens mainly in the brain, originates from the term “type 3 diabetes” to propose this hypothesis.
A provocative new analysis identifying the most significant risk factors for Alzheimer’s disease demonstrates that having a simple lifestyle change, such as exercising, quitting smoking, and losing weight, can potentially prevent half of all cases.
It doesn’t offer a quick fix against the destructive disease, which destroys brain cells and forsakes people silent, uncontrolled, and unable to protect themselves.
That’s because anyone has proven yet that altering these elements will decrease the risk of the disease, which half of all people over age 85 are affected: an estimated 5.2 million Americans and 75,000 people in the Bay Area alone.
The reason for Alzheimer’s is still obscured; like heart disease, it might be generated by a mixture of factors. But according to San Francisco VA Medical Center study, scientists were to start working. “It’s another brick in the wall suggesting that Alzheimer’s doesn’t have to be a passive thing that we wait to come to get us. There are life modifiers that may reduce our risk,” said William H. Fisher of the Alzheimer’s Association.
