Strange visual disturbances occur early in about 10% of Alzheimer’s cases, and when this happens it almost always signals the impending arrival of the disease, a new study finds. The condition is called posterior cortical atrophy (PCA). It involves a sudden difficulty in performing vision-related tasks — for example writing, judging whether an object is moving or stationary, or easily picking up a dropped item. Everyday tasks like these become difficult despite the fact that a person’s eye exam comes out fine. “We need more awareness of PCA, so that it can be flagged by clinicians,” said study co-lead author Marianne Chapleau, of the University of California, San Francisco’s department of neurology. “Most patients see their optometrist when they start experiencing visual symptoms and may be referred to an ophthalmologist who may also fail to recognize PCA,” she said in a UCSF news release. “We need better tools in clinical settings to identify these patients early on and get them treatment.”  To determine just how predictive of dementia PCA might be, Chapleau’s team analyzed data on over 1,000 patients at 36 sites in 16 countries. PCA tended to emerge at a fairly young age — 59, on average. Patients with PCA often failed to accurately copy simple diagrams, had trouble gauging an object’s location or had difficulty visually perceiving more than one object at a…  read on >  read on >

Alcoholics Anonymous is a key means by which millions of Americans deal with drinking problems. However, white Americans are much more likely to engage in the trusted “12-step” program than Black of Hispanic drinkers, a new study finds. Black and Hispanic alcoholics are about 40% less likely to have ever attended an AA meeting, compared to white drinkers, according to analysis of data from the National Alcohol Survey. Researchers also discovered age-related disparities. Among adults younger than 30, less than 5% had ever attended AA versus about 12% of those 30 and older. After accounting for other factors, younger adults still attended AA at a third of the rate of older adults. “This is concerning, because the disparities suggest that these groups — Black, Latinx and emerging adults — are not receiving optimal care,” said lead researcher Sarah Zemore, a senior scientist with the Alcohol Research Group in Emeryville, Calif. AA and other similar support groups have become a staple for treatment of alcohol and substance use disorders, researchers said in background notes. Research has proven these groups can help people achieve lasting recovery. “It’s known that mutual-help groups can be quite effective in initiating and sustaining recovery,” Zemore said. And in the United States, more Americans turn to AA-type groups than specialty substance abuse treatment programs, Zemore noted. It’s not clear why racial and…  read on >  read on >

If you decide to see a therapist, finding one who’s right for you presents one of the biggest early hurdles. “The field of psychology, psychiatry and psychotherapy has advanced over the years, and one of the ways it has advanced is by learning that certain therapies may work best for certain problems,” said Eric Storch, vice chair of psychology in the Menninger Department of Psychiatry and Behavioral Sciences at Baylor College of Medicine in Houston. Storch offers some solid tips for finding the best therapist for your needs: Make a Connection You should feel a sense of connection and comfort when disclosing personal information to a therapist. Being able to talk openly and comfortably is a good sign you’ve found the right therapist. What’s the Plan? Expect a therapist to ask questions about your situation at the first meeting, which will help them figure out the problem and create a treatment plan best suited to deal with it. Their plan should align with therapies proven to work for your particular issue. “In psychotherapy, you want to be looking for people who have a particular expertise in a particular type of problem,” Storch said. For example, people with obsessive-compulsive disorder or anxiety might best be served by cognitive-behavioral therapy. Interpersonal problems would require a different type of therapy. Ask Advocates Patient advocacy groups can provide you…  read on >  read on >

Loneliness can be a killer, but it can be particularly deadly for obese people, who are markedly more likely to experience social isolation. Luckily, a new study shows that addressing it may lower the risk of health complications and an early death for these folks. “To date, dietary and lifestyle factors are the major focus in preventing obesity-related illness,” study author Dr. Lu Qi, interim chair of the department of epidemiology at Tulane University School of Public Health and Tropical Medicine in New Orleans, told CNN. “Our study highlights the importance of taking social and mental health into account in improving health for people with obesity.” Dr. Philipp Scherer, a professor of internal medicine at the University of Texas Southwestern Medical School, wasn’t surprised by the findings. But the results do point to improving “social isolation as a potential remedy for the reduction of mortality,” he told CNN. In the study, researchers looked at data from nearly 400,000 people from the UK BioBank, a large database that has tracked the health of Britons for years. Those included in the research did not have heart disease when the scientists began collecting data for this latest study. They then followed up with the volunteers between March 2006 and November 2021. During that period, all causes of death for people who were obese was 36% lower in those who felt…  read on >  read on >

Two new strategies using deep brain stimulation can improve symptoms of Parkinson’s disease, Duke University researchers have found. Doctors can efficiently improve symptoms of Parkinson’s by simultaneously targeting to key brain structures using a newly developed self-adjusting device, researchers recently reported in the journal Brain. For the past two decades, doctors have used deep brain stimulation (DBS) to treat symptoms of advanced Parkinson’s, which can include tremors, stiffness, and involuntary writhing movements. The technique involves electrodes inserted into a targeted area of the brain. The electrodes act similarly to a heart pacemaker, delivering electrical pulses that help quell symptoms. The two key brain regions targeted by deep brain stimulation are the subthalamic nucleus and the globus pallidus, “which are two structures in the brain closely associated with movement,” said senior author Dr. Dennis Turner, professor of neurosurgery, neurobiology, and biomedical engineering at the Duke University School of Medicine in Durham, N.C. “There are benefits to both locations on their own depending on the patient’s symptoms,” Turner said in a Duke news release, “but we believed placing the electrodes at both locations could be complementary and help reduce medication doses and side effects, as well as implement a completely new approach to adaptive DBS.” Beside targeting both regions at once, researchers also decided to include a technique called “adaptive DBS.” Traditional DBS involves a doctor setting…  read on >  read on >

Black people are five times as likely as others to develop glaucoma and up to 15 times more likely to be blinded by the degenerative eye disease. Now, a new study reports that genetics appears to be at least one factor contributing to this increased risk. Researchers have identified three gene variants that could be fueling Black people’s higher glaucoma risk, according to findings published Jan. 18 in the journal Cell. “Our work is an important step toward defining subgroups of glaucoma, providing the capability for early screening and discovering targetable pathways for personalized therapeutic interventions,” said study co-author Rebecca Salowe, a research project manager with the University of Pennsylvania’s Center for Genetics of Complex Disease in Philadelphia. Glaucoma occurs when fluid pressure starts to increase inside a person’s eye, gradually damaging the optic nerve. For the study, researchers analyzed the genetics of more than 11,200 people of African ancestry. They discovered two gene variants linked to primary open-angle glaucoma, which is the most common form of the disease. Open-angle glaucoma affects as many as nine out of 10 Americans who have glaucoma, according to the Cleveland Clinic. It occurs when resistance builds up in the canals that typically drain excess fluid from the eye. They also found a third variant associated with cup-to-disc ratio, which is a measure of glaucoma severity based on the…  read on >  read on >

Think your kid is safe from exposure to gambling?  Don’t bet on it. “Teens and young adults may have a difficult time going into a casino unnoticed but they have easy access to a variety of betting and gambling options,” said Sarah Clark, co-director of C.S. Mott Children’s Hospital National Poll on Children’s Health. “This expanded accessibility has increased exposure to the risks of underage betting, but there is little regulation or conversation around this problem.” Just 1 in 4 parents who took part in the latest poll said they had talked to their teen about virtual betting. More than half of parents who participated didn’t know their state’s legal age for online gambling, and 1 in 6 said they probably wouldn’t know if their kids were betting online. More than half of states have legalized some form of online gambling in the wake of a 2018 U.S. Supreme Court ruling. Most restrict online sport and casino betting to people 21 years or older, but loopholes exist, along with concerns that teens may bypass security steps. Clark likened online sports betting to fantasy football leagues and March Madness pools that are popular with sports fans, including kids. “Many online gambling options will seem familiar to teens,” Clark said in a news release. “They feel like games kids have been playing on their phones, including features…  read on >  read on >

Depression affects half of the 6 million Americans who struggle with debilitating heart failure.  Now, research shows that two leading modes of treatment — antidepressants and an approach called behavioral activation psychotherapy — work equally well to ease depression among these patients. Behavioral activation psychotherapy works by promoting involvement in activities that the patient enjoys, explained the team at Cedars-Sinai in Los Angeles. “The most important finding here is that patients experiencing depression have a choice in terms of their treatment between therapy or medications,” study lead author Dr. Waguih Ishak said in a hospital news release.  “Patients who prefer not to be on medication can do behavioral activation therapy with similar results,” said Ishak. He’s vice chair of education and research in the hospital’s Department of Psychiatry and Behavioral Neurosciences. In their research, Ishak’s group tracked the mental health of more than 400 heart failure patients over the course of a year. Half of them received antidepressants to help ease their depression, while the other half engaged in behavioral activation psychotherapy. The result: Each treatment approach helped about equally, with patients in either group benefiting from an average 50% reduction in depression symptoms. Antidepressants are effective, Ishak’s group said, but some patients prefer a non-pharmaceutical approach, and behavioral activation psychotherapy may be for them. In the treatment, a therapist helps the patient draw up…  read on >  read on >

Back pain is a double-edged sword. In most cases, it disappears within about six weeks. But when it doesn’t, low back pain is likely to bother you for the long haul, researchers warn. “The good news is that most episodes of back pain recover, and this is the case even if you have already had back pain for a couple of months,” said researcher Lorimer Moseley, a professor of physiotherapy and pain management at the University of South Australia in Adelaide. “The bad news is that once you have had back pain for more than a few months, the chance of recovery is much lower.” More than 570 million people worldwide are affected by low back pain. In the U.S. alone, the bill for treating it added up to $134.5 billion between 1996 and 2016. And costs are increasing. In a review of 95 studies, an international team compared acute low back pain (less than 6 weeks), subacute back pain (6-12 weeks) and persistent low back pain (more than 12 weeks).  They report in the Canadian Medical Association Journal that for folks with new back pain, pain and mobility issues eased significantly in the first six weeks, then slowed. This study closed a gap in a 2012 study from the same team, with new findings showing that many people whose pain lasts more than 12…  read on >  read on >

Winter isn’t kind to your skin. Dry, cold weather causes dryness, and you might even develop “winter rash” — dry, irritated skin that’s red, bumpy, flaky and burns. That’s why it’s prime time to step up your skin care routine. Dr. Oyetewa Oyerinde, assistant professor of dermatology at Baylor College of Medicine in Houston, shared some tips to keep your skin glowing. “During the winter, our skin typically dries out because the air tends to be less humid, and we also use the heater indoors, which leads to even more dryness,” she said in a Baylor news release. “Dry skin is more likely to develop many types of rashes.” That’s why she recommends changing up your usual routine of daily cleansing, moisturing and sun protection. If you usually use lotion, consider using a thicker cream-like moisturizer. If you usually use cream-like moisturizers, consider switching to an ointment-type moisturizer, Oyerinde suggested.  If you enjoy outdoor activities or snow sports, don’t forget your sunscreen.  Following a good skin care regimen will help prevent a winter rash, she said. Your lips and skin around the eyes is especially vulnerable not only to the cold but also to rubbing caused by allergies, colds or flu, she pointed out. Soothing irritated skin is easy. Just grab a jar of petroleum jelly and slather it on affected areas. Petroleum jelly creates…  read on >  read on >
