Memory slips are aggravating, frustrating, and sometimes worrisome. When they happen more than they should, they can trigger fears of looming dementia or Alzheimer’s disease. But there are many mundane—and treatable—causes of forgetfulness. Here are seven common ones: lack of sleep, some medications, an underactive thyroid, drinking too much alcohol, stress, anxiety, and depression. If memory lapses are bugging you, it’s worth a conversation with your doctor to see if any reversible causes are at the root of the problem. Something like getting more sleep, switching a medication, or a stress reduction program could get your memory back on track.

Getting extra calcium from supplements is supposed to be good for your bones. The latest in a string of studies heightens concern that this simple practice could end up being bad for your heart. The results support growing recommendations to get calcium from food, not pills. The latest evidence comes from the NIH-AARP Diet and Health Study, which has followed the health of nearly 400,000 men and women since 1995. Over 12 years of follow-up, men who took more than 1,000 milligrams (mg) of daily supplemental calcium were 20% more likely to succumb to heart disease than those who didn’t take calcium supplements. There was no connection between calcium supplements and heart disease in women (which has been seen in earlier studies), and no connection with calcium from food. This one study isn’t enough to find calcium guilty of heart disease in the first degree. But it’s not the only research to point the accusing finger. This line of research has some experts placing greater emphasis on a nutritious, calcium-rich diet and weight bearing exercise than on calcium supplements for keeping bones strong.
When it comes to relieving the pain of achy joints, many people reach for a pain-relieving pill like aspirin or ibuprofen. There may be a better way. When the source of pain is close to the surface, applying a cream, gel, patch, or spray that contains a pain reliever right where it hurts can ease pain and help avoid some of the body-wide side effects of oral pain relievers. These so-called topical analgesics work best for more superficial joints like the knees, ankles, feet, elbows, and hands. The active ingredient in most topical analgesics is a nonsteroidal anti-inflammatory drug (NSAID) like ibuprofen, naproxen, aspirin, or diclofenac. These medications target inflammation, which contributes to pain, swelling, and stiffness. The advantage of using a topical analgesic is that the medication works locally. Targeting pain more precisely using a medication applied to the skin can help skirt the side effects of oral drugs. This can be a boon for people whose stomachs are sensitive to NSAIDs.
The FDA is urging doctors to lower the starting dose of zolpidem, a popular prescription sleep aid, due to concerns that the drug can linger too long in the body. This causes daytime drowsiness that has led to car accidents. Sleep aids affected by the FDA’s announcement includes generic zolpidem and brand names Ambien, Ambien CR, Edluar, and Zolpimist. The FDA lowered the starting dose for women from 10 milligrams (mg) to 5 mg; for men it is now 5 to 10 mg. The drug should be taken right before going to bed. Taking too much of a sleep drug can give you a “hangover” of daytime drowsiness the next morning that could raise the risk of accidents or falls. Because people respond to medications in their own ways, it’s safest to start taking a sleep drug on a weekend, and start with a dose lower than the maximum recommended starting dose. If you feel drowsy the next day, the dose can be reduced; if it didn’t work, the dose can be increased.
Many adult Americans take aspirin every day, often to prevent a heart attack. Headlines about a study published today linking aspirin use with age-related macular degeneration (AMD) may scare some aspirin users to stop, but that’s the wrong message. In the study, aspirin’s effect on vision was small—far smaller than the lifesaving benefit it offers people with heart. Macular degeneration occurs when something goes wrong with the macula, a small part of the eye’s light-sensing retina. The macula is responsible for sharp central vision. In the new study, published in JAMA, 1.4% of long-term daily aspirin users and 0.6% of non-users developed macular degeneration over a 20-year period. The American Academy of Ophthalmology recommends that people age 65 and older have comprehensive exams at least every other year to check for macular degeneration and other eye problems.
Thanks to an aging population and a lot of direct-to-consumer advertising, many American men of a certain age know to ask about the “little blue pill” or similar medications if they develop erectile difficulties. But an ED drug like sildenafil (Viagra) or its competitors may not always be the best place to start. Since ED can sometimes act like the canary in a coal mine for a future heart attack, it should be approached more systematically. A blood test for testosterone is a good first step. If the testosterone level is low, then trying testosterone replacement restores erections and may add more “pep” and more desire for sex in the first place. If that doesn’t improve erections, an ED drug is a next logical step.
When it comes to keeping healthy and fit, living a mentally active life is as important as regular physical exercise. Just as your muscles grow stronger with use, mental exercise keeps your mental skills and memory in tone. Although any brain exercise is better than being a total mental couch potato, some kinds of “brain work” are more effective than others. The activities with the most impact are those that require you to work beyond what is easy and comfortable. Try these four basic brain-health strategies: Be a lifelong learner. Strain your brain with mentally challenging tasks. Get out of your comfort zone from time to time to challenge your mental skills. Be social. And don’t forget your body—physical activity that gets your pulse thumping helps the mind as well as the heart.
The sleep-robbing condition known as restless legs syndrome (RLS) raises the risk of heart disease in older women about as much as smoking and obesity, according to a new Harvard-based study published online in the journal Circulation. The key sign of RLS is an irresistible urge to move the legs, often accompanied by an uncomfortable “creepy-crawly” sensation. It affects about 2% of adults and is twice as common in women as in men. Symptoms typically flare as people settle into bed, but may also arise when simply resting in a chair or sitting at a desk. Most people with RLS also experience periodic jerking leg motions during sleep. Uncovering this link could help people with RLS pay better attention to their cardiovascular health and potentially ward off a heart attack, stroke, or other cardiovascular condition.
Based on data presented this week at the Union for International Cancer Control meeting in Montreal, a startling 40% of cancers may stem from modifiable causes, such as diet, exercise, tobacco and alcohol exposure, and appropriate screening. Although adapting a healthy lifestyle isn’t an ironclad guarantee against cancer, it can help lower a person’s individual risk.
A recent study in the Archives of Internal Medicine indicates that the risk of having a heart attack is up to 31 times higher immediately following joint replacement surgery. Those relative risk numbers could be terrifying for someone who needs to have a knee or hip replaced. The absolute risk numbers offer some reassurance. In the six weeks following surgery, one in 200 people in the study who got a new hip and one in 500 who had a knee replaced suffered a heart attack. One new point the study underscored is that the elevated risk may last longer than previously thought. Though earlier research had suggested a danger zone lasting four to five days after joint replacement—coincidentally, the period in which many people are discharged from the hospital—the elevated heart attack risk may persist for two to six weeks.
