To Keep Your Smarts, Exercise More than Just Your Brain

Why do some people, as they age, “keep their smarts”—that is, they maintain their cognitive functions well—and others do not? A number of longitudinal studies indicate that the successful agers share four traits:

They are more mentally active.
They are more physically active.
They maintain a sense of their social engagement. In other words, they see themselves as still having roles to play in life—in their families, communities, or even in continuing employment.
They pay attention to controlling the risk factors for disease of the heart and brain. They may stop smoking, control their blood pressure, keep cholesterol within normal limits by diet or medications, and/or recognize and treat diabetes.

Moreover, it appears that these factors reinforce one another: the more of them people follow, the better.

Sleep disorders may raise risk of Alzheimer’s, new research shows - The Washington Post

Sleep disorders may raise risk of Alzheimer’s, new research shows - The Washington Post: Sleep disturbances such as apnea may increase the risk of Alzheimer’s disease, while moderate exercise in middle age and mentally stimulating games, such as crossword puzzles, may prevent the onset of the dementia-causing disease, according to new research to be presented Monday.

Diabetes and Alzheimer’s Disease – What’s The Link? | Brain Blogger

Diabetes and Alzheimer’s Disease – What’s The Link? | Brain Blogger: Recent studies propose a common pathophysiology between diabetes and Alzheimer’s disease. The similarities in the pathophysiology have given way to the thought that Alzheimer’s disease could be viewed as a new form of diabetes mellitus. The reasons for such an implication are not so complex and are as follows.
Amyloid plaques are seen in diabetes and Alzheimer’s disease patients

The pathology of Alzheimer’s disease is still a hotly debated topic. However, researchers have proposed certain characteristic features of Alzheimer’s diseases that are attributed to the damage caused to the brain. They include the formations of certain protein deposits: amyloid plaques and neurofibrillary tangles. The interesting fact is that these deposits are also seen in the brain autopsies of patients who died with diabetes.

Feeding the Brain’s Curiosity Helps Delay Alzheimer’s, Study Says - Bloomberg

Feeding the Brain’s Curiosity Helps Delay Alzheimer’s, Study Says - Bloomberg: Lifelong intellectual activities such as playing music or reading kept the mind fit as people aged and also delayed Alzheimer’s by years for those at risk of the disease who weren’t college educated or worked at challenging jobs, the researchers said in the study published today in JAMA Neurology.

More than 5 million Americans have Alzheimer’s disease, the most common form of dementia, and the number is expected to triple by 2050, according to the Alzheimer’s Association. Today’s findings show that intellectual enrichment pursued over a lifetime may help reduce the number of people who will develop the disease, the authors said.

Newly identified compound may halt progression of Alzheimer's disease

Newly identified compound may halt progression of Alzheimer's disease: Without a steady supply of blood, neurons can't work. That's why one of the culprits behind Alzheimer's disease is believed to be the persistent blood clots that often form in the brains of Alzheimer's patients, contributing to the condition's hallmark memory loss, confusion and cognitive decline.
