A small region deep in the brain might be "ground zero" for Alzheimer's disease, suggest the authors of a new review of scientific literature. It's still early to know for sure, though.
University of Southern California researchers said that the locus coeruleus — a little blue area of the brain stem — releases a chemical called norepinephrine that helps regulate heart rate, attention, memory, and cognition. It may also help prevent Alzheimer's symptoms by protecting brain cells, called neurons, from factors such as inflammation that may hasten the onset of dementia.

A sense of meaning in life may be a critical factor in curbing suicidal thoughts in older adults, new research shows.
It is important for healthcare providers to ask older adults about positive psychological factors, said lead investigator Marnin Heisel, Ph.D., of the Lawson Health Research Institute, London, Ontario, Canada. "We should not exclusively be looking at the negative side of things — depression, hopelessness, psychopathology. Of course, all of those things need to be evaluated, especially in older adults. But even for older adults who are struggling with these sorts of issues, we found that people who were able to identify some sort of meaning in life or particular things that give them a reason for living were significantly less likely to feel depressed, lonely, or suicidal," Dr. Heisel told Medscape Medical News.

The National Institute of Health has shown "without question that addiction is a chronic, medical disease of the brain," Dr. Harold Urschel, chief medical strategist for Enterhealth addiction treatment centers and author of Healing the Addicted Brain, tells Quartz. Alcohol and the other controlled substances are "neurotoxins that cause brain injury to certain people." More than a few studies have shown that drugs and alcohol change the neural structure of the brain and have genetic underpinnings that predispose some people to addiction more than others.

Today's older adults are more likely to live alone than previous generations. Millions of women 65 and over — a full 36 percent — live alone. The number climbs to nearly half for women 75 and over. The reasons are varied. Women often outlive their spouses or partners, or see their children move away. Once widowed, older women are more likely to remain unmarried because men tend to marry younger women. There's been a steep decline in elders living with adult children or other relatives. And 90 percent of seniors say they prefer to age in their own homes.

Avoiding the use of proton pump inhibitors (PPIs) may help prevent the development of dementia, data indicate.
The study, published in JAMA Neurology, examined the association between PPI use, which are often prescribed for the treatment of gastrointestinal diseases, and incident dementia in elderly people.

 Traumatic brain injury, or TBI, is a major cause of death and disability in the United States, contributing to about 30 percent of all injury deaths. Those who survive a TBI, about 3.5 million Americans, face a range of outcomes from effects lasting a few days to disabilities that may last the rest of their lives. Now, a new study suggests that suffering a TBI may lead to a buildup of Alzheimer's-type plaques in the brain, including regions not typically affected by such plaques.

 Two recent reports regarding Alzheimer's disease may send baby boomers in search of their pipes and Mary Jane brownie recipes. A small study showed the consumption of oil containing tetrahydrocannabinol — the active ingredient in marijuana — helped improve behaviors related to dementia, including sleep patterns. Another recent study found that the cells in the eye's retina responsible for the circadian functions influencing sleep are reduced in Alzheimer's disease.
