It’s not sexy but it’s real. Many scientists are now looking at the gut as a primary source of many diseases that plague humankind. Probiotics, the prebiotics that they feed upon in the gut, as well as changes in our diet are being studied as possible methods of preventing or curing major diseases. Read more →

Loneliness as a dementia risk, particularly Alzheimer’s disease (AD), has long been considered solid science. It’s hard to quantify loneliness, as it’s not as simple as whether a person has opportunities to interact with others. Yet, the difficulty of defining loneliness has not kept researchers from studying its impact on health. For example, the National Institutes of Health (NIH) reports study results showing that "After adjustment for other risk factors, older persons with feelings of loneliness were more likely to develop dementia” than people without such feelings.

A procedure that that is already being used for the treatment of some brain diseases is receiving increased attention as a possible treatment for Alzheimer’s disease. Called deep brain stimulation (DBS), an implanted neurostimulator delivers electrical signals that help regulate abnormal signals in the brain caused by the disease. n the U.S., DBS is currently only approved for the treatment of Parkinson’s disease and essential tremor. But the potential for its use is expanding, with more researchers looking into the procedure for epilepsy, depression, bipolar disorder, and now, Alzheimer’s disease. Read more →

Scientists at the University of Edinburgh’s Centre for Cognitive and Neural Systems have found evidence that long-term testing starting well before any signs of Alzheimer’s symptoms are evident could be a valuable tool in detecting which people will need intervention with therapeutic drugs that are now in clinical trials. This type of intervention could possibly halt or even reverse cognitive damage while the patient is still symptom-free. The long-term testing would be done in conjunction with brain scans.

It’s far too easy for onlookers to view someone with dementia as unable to feel pain. Since the disease eventually renders most people helpless and cognitively inexpressive, they can't articulate what hurts or why they are upset. Caring researchers have now brought new insight to this issue. In an article on altered pain processing in patients with cognitive impairment, Medical News Today states that new research shows how wrong previous ideas about what people with cognitive disorders could feel have been.

...Diseases such as attention-deficit/hyperactivity disorder, diabetes, cardiovascular disease and Alzheimer’s have been linked to a high amount of fructose, which is used as an inexpensive sweetener in many ready-to-eat foods. "DHA changes not just one or two genes; it seems to push the entire gene pattern back to normal, which is remarkable," Xia Yang, a senior author of the study and a UCLA assistant professor of integrative biology and physiology. "And we can see why it has such a powerful effect." Read more →

Studies show that many diseases affect ethnic groups differently, with a larger percentage of some groups than others expected to develop these diseases over time. Recently, the first ever study to expand its research with dementia, particularly Alzheimer's, beyond the Black and Caucasian communities has published data that should make us all pay attention. Six ethnic and racial groups within the same geographic population were studied. Read more →

Look young! Feel young! Think young! The constant barrage of information about how being forever young is the only desirable way to live is enough to make even a young person feel old. Now researchers have shown that this ageism is potentially harmful to one's cognitive abilities over the long term. Read more →

We can’t keep these facts buried. Dementia, of which Alzheimer’s is the leading variety, is a family disease in that it affects family dynamics, family income, and family health. It turns couples into care partners. It turns adult children into caregivers for their parents often during the time that they also are caregivers for their young children, which has created the term “sandwich generation.” Read more →

It’s been said that once you know one person with Alzheimer’s, you know one person with Alzheimer’s. In other words: people are unique, and not everyone will respond to a particular treatment. This truth was highlighted in a study based on the combined efforts of the Buck Institute for Research on Aging and UCLA Easton Laboratories for Neurodegenerative Disease Research. Read more →
