Adding Antipsychotic Med to Antidepressant May help Older Adults with Treatment-Resistant Depression
Aripiprazole originally was approved by the FDA in 2002 as a treatment for schizophrenia but also has been used in lower doses as an add-on treatment for clinical depression in younger patients who do not respond to antidepressants alone. The new findings are published March 3 in The New England Journal of Medicine and are to be presented that same day by Eric J. Lenze, MD … [Read more...]
Effect of Dietary Choline Deficiency on Neurologic and System-Wide Health
It's estimated that more than 90% of Americans are not meeting the recommended daily intake of choline. The current research, conducted in mice, suggests that dietary choline deficiency can have profound negative effects on the heart, liver and other organs. Lack of adequate choline is also linked with profound changes in the brain associated with Alzheimer's disease. These … [Read more...]

Blood Levels of ‘Free Range’ DNA may Signal Early Detection of Dementia and Frailty
In a long-term prospective study of more than 600 older participants, Johns Hopkins Medicine researchers say they have evidence that higher levels of cell-free DNA circulating in the blood may signal increased risk of chronic inflammation associated with early signs of frailty and dementia. The findings, published Oct. 11 in the Journal of Alzheimer's Disease, could advance … [Read more...]
Study Uncovers Differences in Saliva Bacteria of Students with Recent Suicidal Thoughts
While there is a growing body of research on mental health and the human microbiome, this is the first study to look at bacterial differences in the saliva of those with and without recent suicidal thoughts, also called suicidal ideation.

New discovery for how the brain ‘tangles’ in Alzheimer’s Disease
University of Queensland researchers have discovered a new 'seeding' process in brain cells that could be a cause of dementia and Alzheimer's disease. UQ's Queensland Brain Institute dementia researcher Professor Jürgen Götz said the study revealed that tangled neurons, a hallmark sign of dementia, form in part by a cellular process that has gone astray and allows a toxic … [Read more...]
Dental experts discover biological imbalance is the link between gum and kidney disease
An imbalance of the body's oxygen producing free radicals and its antioxidant cells could be the reason why gum disease and chronic kidney disease affect each other, a new study led by the University of Birmingham has found. Periodontitis -- or gum disease -- is a common, inflammatory disease which causes bleeding gums, wobbly or drifting teeth and can eventually result in … [Read more...]
A sulfur molecule to block the coronavirus
The cell membrane is impermeable to viruses: to get inside and infect a cell, they use a range of strategies to exploit the cellular and biochemical properties of the membranes. The thiol-mediated uptake of organic molecules similar to alcohols, where oxygen is replaced by a sulfur atom, is one of the entry mechanisms, with its use by Human Immunodeficiency Virus (HIV) … [Read more...]
Talc and petroleum jelly among the best lubricants for people wearing PPE, study finds
For frontline healthcare workers during the COVID-19 pandemic, wearing personal protective equipment (PPE) like face visors, googles, and respiratory protective equipment is an essential part of working life.

People who watch lots of TV prefer thinner women, which suggests that TV can influence opinions about preferred body shapes, researchers say. Their study included 299 men and women in a remote area of Nicaragua, in Central America. Participants were either regular TV viewers or had little or no access to it. While regular viewers preferred thinner females, those with little or … [Read more...]
