Weight-maintaining hormone key to brain-signal transmission. A study more closely links obesity to dementia, finding that leptin, a hormone that helps maintain normal body weight, is associated with better signal-transmitting brain white matter in middle-aged adults.

New research is more closely linking obesity to dementia.

Higher levels of leptin, a hormone that helps maintain normal body weight, is associated with better signal-transmitting brain white matter in middle-aged adults, according to a study by The University of Texas Health Science Center at San Antonio (UT Health San Antonio).

“The findings support the known role of leptin variations in late-life d...

Researchers at the Icahn School of Medicine at Mount Sinai and others have harnessed the power of machine learning to identify key predictors of mortality in dementia patients.

The study, published in the February 28 online issue of Communications Medicine, addresses critical challenges in dementia care by pinpointing patients at high risk of near-term death and uncovers the factors that drive this risk.

Unlike previous studies that focused on diagnosing dementia, this research delves into predicting patient prognosis, shedding light on mortality risks and contributing factors in various kinds of dementia.

Dementia has emerged as a major cause of death in societies with increasin...

Researchers from Charité and McGill University quantify association between Helicobacter pylori and Alzheimer’s disease. Infection with the stomach bacterium Helicobacter pylori could increase the risk of developing Alzheimer’s disease: In people over the age of 50, the risk following a symptomatic infection can be an average of 11 percent higher, and even more about ten years after the infection, at 24 percent greater risk. These are the findings of a study by Charité — Universitätsmedizin Berlin and McGill University (Canada), now published in the journal Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.* The researchers analyzed three decades’ worth of patient data.

As today’s populations age, dementia is set to become more common, tripling in prevalence in ...

Dementia is one of the major causes of disability and dependency among older people worldwide, affecting thinking and behaviors as you age. But what if you could stop this degenerative disease in its tracks?

A world-first study from the University of South Australia could make this a reality as new genetic research shows a direct link between dementia and a lack of vitamin D.

Investigating the association between vitamin D, neuroimaging features, and the risk of dementia and stroke, the study found:

• low levels of vitamin D were associated with lower brain volumes and an increased risk of dementia and stroke
• genetic analyses supported a causal effect of vitamin D deficiency and dementia.
• in some populations as much as 17% of dementia cases might be prevented by increasing everyo...
