Older adults may assume bouts of forgetfulness or “brain fog” are a natural part of aging. But one possible explanation is that the problem is a side effect from common medications, in particular sleep aids and pain killers. Older adults who have recently begun taking a new medication or increased their dosage should monitor their memory problems and then share the information with their doctor to see if adjustments should be made to their medication regimen.

For decades, researchers have used body mass index (BMI) to estimate a person’s body fat mass and predict possible health risks. While BMI is helpful, it can’t accurately measure the type of fat people accumulate, especially among older adults. Monitoring one’s waist size with a simple measuring tape may be a better option.

Ongoing research suggests that heart-healthy diets like the Mediterranean and DASH diets that emphasize plant-based foods also can lower a man’s risk of prostate cancer and even help slow its spread. Researchers point to the diets high amounts of antioxidants and omega-3 fatty acids as possible reasons.

For decades, blood pressure treatment was dictated by a person’s numbers, with a blood pressure less than 140/90 millimeters of mercury (mm Hg) considered normal. But evidence has proved this to be an inadequate goal. Research now suggests an individualized approach to managing blood pressure that considers other heart health risks, lifestyle habits, and family history may be a better way to ward off heart attacks and strokes.

A wireless, battery-free device that naturally absorbs into the body within two months may one day be a safer alternative to temporary pacemakers.

Using a device that strengthens breathing muscles for just five minutes a day may help lower blood pressure. The small handheld device provides resistance as a person inhales and exhales, providing what’s known as inspiratory muscle strength training.

A continuous glucose monitor (CGM)—a small device placed on the arm or belly that measures blood sugar every few minutes—may help people with diabetes recognize the eating and exercise habits that hinder (or help) them control their blood sugar. CGM readouts, which are displayed on a smartphone or portable monitor, show your blood sugar values, trends, and the percentage of time that your blood sugar is in a ”good control” range. Medicare covers CGMs for people who inject insulin at least three times a day or use an insulin pump to control their blood sugar.

People with atrial fibrillation who develop or face a high risk of serious bleeding from anti-clotting drugs may be candidates for procedures that block or remove a part of the heart where dangerous blood clots form. About 90% of blood clots in the heart form in the left atrial appendage (LAA), a small pouch that protrudes from the top of the heart. Two procedures prevent clots from escaping from the LAA and causing a stroke. One delivers a device that blocks the opening of the LAA; the other removes most of the LAA during heart surgery done for another reason.

A rapid heart rate—tachycardia—is a key feature of postural orthostatic tachycardia syndrome, or POTS, a mysterious condition that involves the nervous system and can cause a constellation of symptoms, including fatigue, shortness of breath, headaches, and brain fog, as well as pain in the chest, extremities, or elsewhere in the body. At least half of all cases of POTS are thought to be triggered by an infection (such as mononucleosis), which then spurs inflammation or an autoimmune response. Treatment includes drinking lots of water, eating lots of salt, and graded exercise training.

Pomegranates are rich in antioxidants that help quell inflammation; the fruit may also help lower LDL and blood pressure.
