New research is untangling the complex relationship between symptoms of depression and losses in memory and thinking that often emerge together with Alzheimer’s disease. In fact, the new data suggests that “depression symptoms themselves may be among the early changes in the preclinical stages of dementia syndromes,” explained study lead author Dr. Jennifer Gatchel. She works in the division of geriatric psychiatry at Massachusetts General Hospital in Boston. In the study, researchers examined brain scans and other data gathered over seven years from 276 older adults enrolled in the Harvard Aging Brain Study. All of the participants were still living independently in the community at the beginning of the study and were considered healthy. However, the analysis revealed a significant link between worsening depression symptoms and mental decline over two to seven years, and both of these trends seemed to be linked to a buildup of amyloid protein in brain tissue. The slow accumulation of amyloid has long been known as a hallmark of Alzheimer’s disease. “Our research found that even modest levels of brain amyloid deposition can impact the relationship between depression symptoms and cognitive [thinking] abilities,” Gatchel said in a hospital news release. The new insight that depression symptoms might be part of the Alzheimer’s process could further research into the prevention or treatment of the illness, she added. It “raises the possibility…  read on >

For parents of a child with autism, communication is often the No. 1 hurdle. But what if there were a simple way to help them get their youngster talking? A new study suggests there just might be. It’s called “pivotal response treatment” (PRT). And those who have tried it say it can open up a whole new verbal world for kids with limited speech and inhibited social skills. “My son was having meltdowns all the time because he couldn’t express what he wanted or needed,” said Heidi Pim, a kindergarten teacher in Palo Alto, Calif., whose son James, 8, was diagnosed as a toddler with autism and speech delays. “We would try our best to figure out what he wanted or needed, so we could give it to him, but often we couldn’t,” she said. “Because he didn’t have any vocabulary. And his frustration and aggression would just turn into situations everywhere I would take him. At shopping malls, airports, everywhere.” James was already undergoing standard “applied behavioral analysis” (ABA) treatment. Considered the gold standard among autism interventions, it aims to teach social skills through heavy monitoring, repetition and positive reinforcement of good behavior, typically in a clinical setting. PRT has roots in ABA. But it aims to keep the child in his or her usual setting, and relies on techniques that are easy for…  read on >

Want to reduce your risk of dementia? Take care of your heart. That’s the takeaway from a new study that suggests good heart health in middle age could lower your odds for problems with thinking and memory later in life. The study included nearly 7,900 British adults who did not have heart disease or dementia at age 50. Over an average 25-year followup, 347 cases of dementia were diagnosed among participants. Average age at diagnosis: 75. After taking other factors into account, researchers linked a higher score at age 50 on seven healthy habits outlined in the American Heart Association’s “Life Simple 7” with a lower risk of dementia later in life. The Life Simple 7 assesses smoking, diet, physical activity, fasting blood sugar, blood cholesterol, blood pressure and body mass index (a measure of body fat based on height and weight). Dementia rates were 1.3 per 1,000 person years among participants who had high scores on heart healthy habits, compared to 3.2 per 1,000 for low-scorers, according to the study published Aug. 7 in the BMJ. A better score at age 50 was also associated with higher overall brain and gray matter volumes in MRI scans 20 years later. Though the study could not prove that heart-healthy living actually caused dementia risk to drop, the researchers said their findings support public policies to improve…  read on >

Thinking of picking up an electric fan to help keep you cool and protect your health during the next heat wave? You might want to think again. Electric fans might make you feel cooler, but they can actually increase your risk of becoming heat sick and even dying from a heat stroke, the evidence shows. Electric fans could contribute to a potentially dangerous increase in a person’s core heat if outdoor temperatures exceed 95 degrees Fahrenheit, a recent Cochrane evidence review says. “The fan actually will be blowing air that is hotter than our body at us,” said co-author Mike Clarke, director of the Northern Ireland Clinical Trials Unit at Queen’s University Belfast. It’s like switching on an electric oven’s convection fan to speed up the cooking process, the researchers said. Meanwhile, another new study found that electric fans are particularly dangerous during very hot and dry conditions, but can help lower core temperatures and heart strain in hot, humid weather. That study appears in the Aug. 5 issue of the Annals of Internal Medicine. Electric fans are seen as a cheap way to help people cope with the several days of high temperatures that make up a heat wave, researchers for the Cochrane review said. Global warming means heat waves will become more frequent, and they can have terrible health consequences. As many as…  read on >

In the quest for more plant-based protein sources, yellow peas have been getting a lot of good press. And the number of packaged foods enhanced with this “pea protein” has tripled in the last few years. But dried split peas, whether yellow or green in color, were an excellent food choice long before they achieved their overnight superstar status. A mere quarter-cup, measured dry (uncooked), will yield 11 to 12 grams of protein, 13 to 16 grams of fiber and just 180 calories. Tip: Read labels on bags of dried peas since these counts vary slightly. Peas are common legumes or “pulses.” While not a complete protein, like meat or chicken, peas have important amino acids including isoleucine, leucine and valine, needed for building muscle. Keep in mind that foods with just the pea protein extract are missing yellow peas’ fiber, B vitamins and a wide variety of essential minerals and phytochemicals. So rather than paying up for products with added pea protein, especially if it’s the only healthy ingredient in the box, consider adding whole split peas to your diet with meals you make at home. Dried peas are perfect for do-ahead meals. Take a few minutes to cook up a batch, and then use them in recipes throughout the week. They form the base of many Indian dishes and hearty soups. They can…  read on >

Pile those vegetables and fruits high when you sit down to eat, and your heart will thank you. A diet rich in plant-based foods translated into fewer heart problems in a new study. For the study, the researchers analyzed data collected from more than 10,000 middle-aged U.S. adults who were followed from 1987 through 2016. None had heart disease at the start of that period. The participants’ eating habits were analyzed and their eating patterns were grouped according to the proportion of plant-based foods they ate versus the proportion of animal-based foods. Compared to those who ate mostly animal-based foods, those who ate mostly plant-based foods had a: 16% lower risk of heart attack, stroke, heart failure and other heart problems; a 32% lower risk of death from heart disease; and a 25% lower risk of death from any cause during the study period. The study was published online Aug. 7 in the Journal of the American Heart Association. “While you don’t have to give up foods derived from animals completely, our study does suggest that eating a larger proportion of plant-based foods and a smaller proportion of animal-based foods may help reduce your risk of having a heart attack, stroke or other type of cardiovascular disease,” said researcher Casey Rebholz. She’s an assistant professor of epidemiology at Johns Hopkins Bloomberg School of Public Health,…  read on >

So-called “conversion therapy” can trigger depression, post-traumatic stress disorder, and suicidal thoughts and attempts, and it should be banished in the United States, medical experts say in a new report. Conversion therapy is used in an attempt to change a person’s sexual orientation or gender identity, most typically to turn someone who is gay into a “straight” person. Electroshock therapy, chemical drugs, hormone administrations and surgery are among the methods that have been used in conversion therapy, noted a team of experts reporting Aug. 8 in the New England Journal of Medicine. While the use of such extreme methods has declined, other types of conversion therapy can still harm U.S. children, teens and adults, according to the report. Only 18 U.S. states have banned conversion therapy for people younger than 18, and no states have banned conversion therapy for adults. “As a result of the lack of regulation on these ‘therapies,’ many adults and children continue to be defrauded, harmed and traumatized in the U.S. every day,” said report lead author Dr. Carl Streed, Jr. He is a primary care physician at Boston Medical Center (BMC) and an assistant professor of medicine at Boston University School of Medicine. “In addition to the health problems associated with conversion therapies, these practices also carry serious economic burdens for LGBTQ [Lesbian, Gay, Bisexual, Transgender, Queer and Questioning] people…  read on >

Video games carry labels with an age-related rating, typically based on the level of violence, strong language and sexual content. But that’s not the only guideline to consider. An industry group called the Entertainment Software Rating Board (ESRB) sets the ratings. Look closely at the video game box or information on a game app and you’ll also find “content descriptors.” There are 30 in all. These are more specific details about what led to the game’s rating — from the amount of blood and gore, to sex, to substances like alcohol and drugs. Also look for mention of “interactive elements.” These are additional game features, such as a player’s ability to interact with other players, and purchase goods and services through the game or app. You should consider interactive elements and content descriptors as carefully as age appropriateness when deciding if a game is right for your child. The content descriptors, in particular, give you an idea of what your child will see during the game. Sampling of Content Descriptors: Alcohol reference Drug reference Intense violence Nudity Real gambling Sexual violence Tobacco use According to studies done in the United States and in the United Kingdom, one of the most under-reported content descriptors is smoking. In one survey, researchers found that only 8% of games that featured smoking carried the tobacco descriptor. The U.S. Surgeon…  read on >

As kids head back to school, it’s important for parents to keep potential asthma and allergy challenges in mind. “In the fall, allergists see an increase in kids’ visits for allergies and asthma because of a combination of factors,” said Dr. Todd Mahr, president of the American College of Allergy, Asthma and Immunology (ACAAI). “And hospitals see what’s known as the ‘September Spike’ because kids who have been off asthma controller medications for the summer start experiencing flare-ups in the fall.” As a new school year begins, kids are exposed to allergens in the classroom, on playing fields and in the cafeteria that many probably haven’t run into all summer, he said in an ACAAI news release. On top of that, it’s ragweed season — a terrible time of year for kids who are allergic. Mahr suggests parents meet with their child’s allergist this month to create an allergy action plan. Parents should also try to identify potential asthma and allergy triggers that their children may encounter at school. These may include chemical compounds from new carpeting, pollen drifting into classrooms through open windows, or mold in bathrooms. Parents should discuss potential triggers with teachers and school administrators to help ease symptoms. Children with asthma or allergies should still be able to play any sport as long as they follow their allergist’s advice, according to…  read on >

A small electric “tickle” to the ear may affect the body’s nervous system, and British researchers claim this can promote overall well-being and may potentially slow down some effects of aging. The tickle treatment is called transcutaneous vagus nerve stimulation (tVNS). The procedure involves placing custom-made clips containing electrodes on the part of your ear called the tragus; that’s the small, pointed tip above your ear lobe. A small electrical current is delivered through the clips to affect the vagus nerve. The vagus nerve is part of the autonomic nervous system, which is responsible for body functions you don’t think about, like blood pressure, temperature and heart rhythm. The study authors suggest that the device may help balance the autonomic system. “We saw that just two weeks of daily tVNS helped to re-balance the levels of activity in the two branches of the autonomic nervous system,” said Susan Deuchars, one of the study’s authors. She’s director of research in the School of Biomedical Sciences at the University of Leeds in England. “These branches normally work in balance to allow healthy levels of activity. As we age — and also in certain clinical conditions — this balance changes so that the sympathetic branch predominates and this can be detrimental for health. tVNS daily seems to redress the balance of this activity towards that associated with healthy…  read on >
