Dementia

We all know exercise is good for preventing physical health problems, but could it also be good for preventing cognitive problems? A study published in Mental Health and Physical Activity suggests that low levels of physical activity can increase the...

When the disease is well reproduced by the model, researchers can assume that a treatment that works on it will be likely to work in people with the disease. Cell cultures and organoids from patients are particularly promising because of...

Drinking coffee may reduce your risk of Alzheimer’s disease, according to findings published in the journal Frontiers in Aging Neuroscience. The study followed a sample of older adults for 10 years and found that those who consumed more coffee showed slower...

A good night’s sleep has always been linked to better mood, and better health. Now, scientists have even more evidence of just how much sleep – and more specifically our circadian rhythm, which regulates our sleep cycle – is linked...

Beta-amyloid and tau are two proteins that serve useful functions in the brain, but in Alzheimer’s disease – the most common form of dementia – they go rogue and destroy brain cells (neurons). This happens when beta-amyloid forms clumps on...

Since the human genome was first mapped, scientists have discovered hundreds of genes influencing illnesses like breast cancer, heart disease and Alzheimer’s disease. Unfortunately, Black people, Indigenous people and other people of color are underrepresented in most genetic studies. This...

A recent study appearing in the Journal of Neuroinflammation has brought further clarity to the role of astrocytes in the beneficial effects of voluntary exercise on patients with Alzheimer’s disease. The effects of increased, voluntary physical exercise on cognitive functions...

Many people do not want to think about dementia, especially if their lives have not yet been touched by it. But a total of 9.9 million people worldwide are diagnosed with dementia each year. That is one person every 3.2...

Genetics may predispose some people to both Alzheimer's disease and high levels of blood lipids such as cholesterol, a common feature of cardiovascular disease, according to a new study by an international team of researchers led by scientists at UC...

More than 30m people worldwide suffer from Alzheimer’s disease – the most common form of dementia. Unfortunately, there is no cure, only drugs to ease the symptoms. However, my latest review, suggests a way to treat the disease. I found...

New research indicates that some autobiographical memories are more vulnerable to Alzheimer's disease and dementia than others. The study examined 11 patients with a clinical diagnosis of probable Alzheimer’s disease and 13 patients with frontotemporal dementia. Another 23 healthy older...

A new study of Alzheimer's disease by Fiona Kerr and Linda Partridge at University College London, uses mouse and fruit fly models to show that Keap1, which inhibits the protective protein Nrf2, is a promising target for new preventative drugs...

Alzheimer’s disease is a progressive brain disease that eventually strips sufferers of their ability to remember, communicate and live independently. By 2050, it is projected to affect nearly 14 million Americans and their families, with an economic cost of one...

Does a patient have depression or a cognitive disorder (CD) such as Alzheimer's disease or both? Since both disorders have overlapping symptoms, how can a clinician tell them apart to make an appropriate diagnosis? In a new article published in...
