(HealthDay News) — Breathing exercises can help you relax and manage stress, says the Arizona Center for Integrative Medicine. The center suggests using the 4-7-8 breath exercise: Exhale completely through your mouth. Close your mouth and inhale through your nose to a mental count of 4. Hold your breath for a count of 7. Exhale through your mouth to a count of 8. Repeat the cycle three more times for a total of four breaths.

(HealthDay News) — About 4 percent of adults have attention-deficit hyperactivity disorder (ADHD), says Harvard University Medical School. Adults with ADHD tend to have more difficulty with attention and memory, rather than with hyperactivity, as with children. To help manage ADHD in adults, the school suggests: Consider medications such as stimulants, non stimulants and antidepressants. Learn more about ADHD and encourage your family and spouse to learn, too. Establish realistic expectations and achievable goals. Avail yourself of cognitive behavioral therapy or coaching.

The holiday season can give you real headaches, but you can take action to prevent them, an expert says. To reduce stress, make plans well in advance and know your limits, advised Dr. Bing Liao, a neurologist at Houston Methodist. “The nature of the holiday season already increases stress levels, so finding small ways to reduce schedule stress can help ward off a headache,” Liao said in a hospital news release. “This can mean planning well in advance to avoid the hassle of making last minute travel plans, or deciding not to attend a party at the end of a long day.” Be sure you have an adequate supply or a refill of your prescription medications before the holidays, she advised. Missing doses or cutting back could trigger a headache or even serious side effects. “Don’t binge anything during the holidays — food, alcohol, or television,” Liao said. “We all know how a hangover can affect the brain, but most don’t realize that overeating can also trigger a headache. And having the next day off from work doesn’t mean you should stay up late watching holiday movies. The brain needs the same amount of sleep during the holidays as it does the rest of the year, so stick with your usual bedtime.” Running holiday errands can lead to skipped meals and dehydration, which can trigger…  read on >

Playing cards and board games like chess, bingo and Scrabble might be the mental workout you need to keep your wits as you age, Scottish researchers suggest. People in their 70s who regularly play board games score higher on tests of memory and thinking skills than those who don’t. And 70-somethings who step up their game-playing are more likely to maintain thinking skills as they age, researchers say. “Playing board, card and word games may protect people from cognitive decline, but this study wasn’t an intervention, so we can’t say that for sure,” said lead researcher Drew Altschul, a postdoctoral research fellow at the University of Edinburgh. “But it, at very least, is fun, inexpensive, and it certainly won’t hurt you.” He doesn’t think it’s the social aspect of these activities that provides this brain-protective effect, but rather the challenge of the games themselves. Unlike reading, writing, taking classes, visiting museums, libraries or friends and relatives, games appear to more actively engage abilities like memory, thinking speed and reasoning, Altschul said. “So, this fits with what we call the ‘use it or lose it’ theory, that exercising your mental abilities more keeps them in better shape,” he said. For the study, Altschul and his colleagues tested the memory, problem-solving, thinking speed and general thinking ability in nearly 1,100 70-year-olds. The tests were repeated every three…  read on >

Headache and migraine patients, take note: medical marijuana may help ease your pain. The findings follow an analysis of data collected by a Canadian phone app that gathered feedback offered by 1,300 headache sufferers and nearly 700 migraine sufferers who used marijuana to treat their head pain. “We found that self-reported headache and migraine severity were reduced by nearly 50% from before to after cannabis use,” said study author Carrie Cuttler. She is an assistant professor in the department of psychology at Washington State University in Pullman, Wash. But a lot of unanswered questions remain. For one, it’s not clear if pot was any better at cutting down headache pain than conventional medicine. “We didn’t directly compare cannabis to conventional treatments,” said Cuttler, “so we don’t know if it is more or less effective.” Also, the jury remains out as to what particular compound might be causing the reductions. The team found that when it came to head pain control, it didn’t matter how much tetrahydrocannabinol (THC) or cannabidiol (CBD) was in a particular batch of pot. THC and CBD are the most commonly studied ingredients in marijuana, Cuttler’s team noted. “[So] it could be one of the other 100-plus phytocannabinoids in the cannabis plant,” she said, adding that “there is simply not enough research on these other constituents to know right now.” At the…  read on >

(HealthDay News) — Knee pain is common, especially in highly active people, says the Cedars-Sinai hospital system. Women, people with a high body mass index and the elderly are at a greater risk of knee pain. Cedars-Sinai mentions these common causes: Overuse of the knee. Inflammation in tissues around the knee. Misalignment of the kneecap. Damage to ligaments, nerves or bone in the area. Injury. To diagnose the reasons for your knee pain, your doctor will perform an exam to test the knee’s range of motion, strength and areas of soreness. Sometimes, an X-ray or MRI may be needed to determine the cause of pain.

A small, preliminary study suggests that a brain area called the hypothalamus appears to be about 6% smaller in women who use birth control pills. But exactly what that means isn’t yet clear. In this study, women on the pill had statistically significant increases in anger. Researchers also found a possible link with depression symptoms. The good news: They didn’t see any difference in women’s mental performance. And women who use the Pill shouldn’t search for other forms of birth control based on these findings, researchers said. “There isn’t enough data here for anyone to worry,” said study author Dr. Michael Lipton. “There’s more than a 50-year history of birth control pills. We’re not advising any changes (in your contraception) based on this preliminary finding.” Still, he added, there may be clinical consequences that this study was too small to find. Lipton is associate director of the Gruss Magnetic Resonance Research Center at Albert Einstein College of Medicine, in New York City. Located at the base of the brain, the hypothalamus produces hormones. It also helps regulate essential body functions like temperature, sleep and heart rate, the researchers said. “There’s a lot of stuff packed in there,” Lipton said. “The hypothalamus covers a lot of basic body functions, like sleep regulation, reproductive regulation, ovulation, the menstrual cycle, sex drive, appetite, mood, reward-related behavior and water…  read on >

(HealthDay News) — American ginseng is an herb that people take by mouth as a stimulant, to reduce stress, or to boost the immune system, says MedlinePlus. American ginseng has different medicinal effects from the Siberian and Asian varieties. Here’s what MedlinePlus says about American ginseng: Side effects may include diarrhea, itching, insomnia, headache and nervousness. Never take ginseng if taking warfarin (Coumadin). Use caution if taking ginseng with MAOIs, antidiabetes drugs or immunosuppressants. Do not take ginseng if you are pregnant.

Obese teenagers can have certain brain differences from their thinner peers — changes that might signal damage from inflammation, a new, preliminary study suggests. Using advanced MRI techniques, researchers found that obese teenagers tended to have signs of decreased “integrity” in the brain’s white matter. White matter contains the fibers that connect different areas of the brain. In this case, lower white-matter integrity was seen in a brain region related to emotional control and “reward” seeking. The findings, based on 120 teenagers, are considered preliminary. Experts said it’s not clear what they might mean. But the findings add to evidence linking obesity to certain brain structure differences. Recent studies of middle-aged adults, for example, have found evidence of brain tissue “shrinkage” among those with high levels of body fat — particularly around the belly. One possibility is that excess amounts of body fat directly harm the brain through inflammation, the researchers suggested. In the new study, there was a correlation between decreases in white matter integrity and higher levels of certain inflammatory substances in the blood. Teens with those brain changes also tended to have higher levels of the hormones leptin and insulin. Leptin is involved in appetite control, while insulin regulates blood sugar levels. Dr. Harold Bays is a fellow of the Obesity Medicine Association and medical director of the Louisville Metabolic and Atherosclerosis…  read on >

Popularized in movies, the phrase, “You’ll shoot your eye out,” is often repeated jokingly whenever someone talks about BB or paintball guns. But it’s no laughing matter. These “non-powder” guns can cause serious, life-altering injuries, and these injuries are now happening far more often. In fact, a new study found that while the overall rate of injuries due to BB and paintball guns has dropped around half since 1990, the rate of eye injuries has risen by 30%. “These findings raise a red flag. Non-powder firearm injuries are among the most serious injuries we see to the eye, with fireworks a close second,” said study senior author Dr. Gary Smith, who directs the Center for Injury Research and Policy at Nationwide Children’s Hospital in Columbus, Ohio. People sometimes dismiss these types of firearms as “toy” or “starter” guns, but Smith said they can cause very serious injuries, and even deaths. “I’ve seen a BB gun penetrate the chest. I’ve seen a pellet gun penetrate the skull. Eye injuries from non-powder firearms can result in partial or complete blindness,” Smith said. Non-powder firearms include BB, pellet, airsoft and paintball guns. These guns use air pressure, carbon dioxide pressure or a spring-loaded mechanism to shoot. They may propel metal or plastic projectiles of varying shapes and sizes. The speed at which these guns shoot varies, according to…  read on >
