Scientists Propose New Mechanism Driving Alzheimer's Disease

Scientists Propose New Mechanism Driving Alzheimer`s DiseaseWEDNESDAY, Oct. 5, 2022 (HealthDay News) -- Amyloid-beta plaques have long been linked to Alzheimer's disease, with some scientists theorizing that the plaques actually cause the degenerative brain disease.But a new study suggests that the plaques are actually a symptom of what's going on in the brain, rather than the cause of Alzheimer's.Instead, decreasing levels of the "normal," water-soluble form of amyloid-beta is the real culprit behind Alzheimer's, a research team argues in the Journal of Alzheimer’s Disease."The paradox is that so many of us accrue plaques in our brains as we age, and yet so few of us with plaques go on to develop dementia,” said lead researcher Dr. Alberto Espay. He's director and endowed chair of the Center for Parkinson's Disease and Movement Disorders...

Suicide Risk Rises Sharply in People Diagnosed With Early-Onset DementiaTUESDAY, Oct. 4, 2022 (HealthDay News) -- Thoughts of suicide are often a first reaction to a diagnosis of dementia before age 65, a new study suggests.Suicide risk is highest in the first three months after the dementia diagnosis and if the patient already has a psychiatric disorder, British researchers found. For those younger than 65, suicide risk was nearly seven times higher than in patients without dementia.Overall, however, when patients of all ages were assessed, there was no statistically significant increase for suicide, concluded the research team led by Danah Alothman, of the University of Nottingham in England."I regularly encounter the effects of the diagnosis of dementia as well as the consequences that this disease has on patients and their loved ones," said Dr. Marzena...

Babies Might Trigger Brain Changes in New Dads

Babies Might Trigger Brain Changes in New DadsTUESDAY, Oct. 4, 2022 (HealthDay News) -- When men become parents, a lot changes in their lives -- less sleep and more time devoted to taking care of their children come to mind -- but new research now suggests that distinct changes also unfold in a new father's brain.Researchers scanned the brains of new fathers to discover and study those changes after suspecting this would be the case and seeing evidence from animal studies that new fatherhood would be one of the times when a man's brain would show enhanced neuroplasticity. New fatherhood is an adaptive time, when dads are learning how to care for their babies, read their signals and communicate with them, explained senior study author Darby Saxbe, a professor of psychology at the University of Southern California."All of those...

Gut Microbes Could Play Role in HIV Infection

Gut Microbes Could Play Role in HIV InfectionTUESDAY, Oct. 4, 2022 (HealthDay News) -- Could key differences in the trillions of bacteria found in the human gut actually affect the risk of becoming infected with HIV? A small, new study suggests the answer may be yes.The intriguing possibility stems from a detailed analysis of the gut bacteria ("microbiomes") of 55 men, all of whom indicated they have sex with other men.About half of the men went on to become infected with HIV; the other half did not. And investigators found notable pre-infection differences in the amount of certain gut bacteria found in the two groups.“This might suggest that there is a connection between these gut bacteria and HIV risk,” said study author Dr. Jennifer Fulcher. She is an assistant professor and staff physician in the department of...

AHA News: Heart Risk Factors, Not Heart Disease Itself, May Increase Odds of COVID-19 Death

AHA News: Heart Risk Factors, Not Heart Disease Itself, May Increase Odds of COVID-19 DeathTUESDAY, Oct. 4, 2022 (American Heart Association News) -- Seeking to clarify connections between pre-existing heart disease and COVID-19, a study of critically ill patients has found their risk of dying from COVID-19 may stem not directly from heart disease, but from the factors that contribute to it.People with heart disease have been, and continue to be, at higher risk of developing severe COVID-19, according to the Centers for Disease Control and Prevention. The new study, published Tuesday in the American Heart Association journal Circulation: Cardiovascular Quality and Outcomes, suggests cardiovascular risk factors – such as being older and whether a person smoked – were the main contributors to serious illness, rather than heart disease itself.COVID-19 is known to cause...

'I'm Not the Doctor for You': Disabled Americans Face Discrimination Seeking Care

`I`m Not the Doctor for You`: Disabled Americans Face Discrimination Seeking CareTUESDAY, Oct. 4, 2022 (HealthDay News) -- Over 30 years since the passage of the Americans with Disabilities Act (ADA), some doctors harbor biases toward people with disabilities, and even actively avoid accepting them as patients, a new study finds.In focus group discussions with about two dozen U.S. doctors, researchers found that many said they lacked the knowledge and skill to care for patients with disabilities. Even basic physical accommodations, like accessible buildings and medical equipment, were an issue.When asked how they measured the weight of a wheelchair user, some doctors said they sent the patient to a supermarket, grain elevator or zoo.But while some doctors said they did the best they could, others expressed negative attitudes saying patients with disabilities were...

COVID Vaccine Myths Drive Low Rates of Uptake Among U.S. Kids

COVID Vaccine Myths Drive Low Rates of Uptake Among U.S. KidsTUESDAY, Oct. 4, 2022 (HealthDay News) -- Almost 8 in 10 U.S. adults have received their primary COVID-19 vaccine series, but only 31% of children ages 5 to 11 have done the same, according to a new report based on late September figures from the U.S. Centers for Disease Control and Prevention.The reason for the discrepancy? A willingness to accept safety misinformation, say researchers from the Annenberg Public Policy Center of the University of Pennsylvania.The researchers found that U.S. adult hesitancy to receive COVID-19 vaccines was associated with misbeliefs about vaccines in general -- notions that they may contain toxins, and false fears about specific vaccines like the measles, mumps and rubella shot (MMR). But even those who had themselves been vaccinated might hesitate to...
