Leadless pacemakers, which are no bigger than a multivitamin pill, are far less prone to complications that traditional pacemakers, which have long leads (wires). These wires may become infected, dislodged, frayed, or broken. Scar tissue or blood clots can form around the leads, which may hinder blood flow and cause pain and swelling. Thanks to recent advances, most people who need pacemakers may now be candidates for leadless devices. However, doctors have less experience with what happens with leadless pacemakers over the long term—and they cost two to three times as much as a traditional pacemaker.

Air travel tips for people who have or are at risk for heart disease include bringing extra prescription medications in a carry-on bag and drinking water—but not alcohol—during the flight. When taking medications (especially blood pressure and anti-clotting drugs), people should try to schedule their doses based on their home time zone. On a long flight, walking a little every hour or so will help improve circulation in the legs; so can flexing the feet and circling the ankles. Doing so may reduce the chance of developing a blood clot, although the overall risk of such clots (known as deep-vein thrombosis) is quite low.

A 2024 study suggests that older adults who are chronically lonely are significantly more likely to have a stroke.

Restless legs syndrome (RLS) affects up to 10% of Americans and twice as many women as men. Risk factors include age, genetics, iron-deficiency anemia, and pregnancy. A variety of therapies can alleviate symptoms, which are dominated by creepy-crawly, sometimes painful leg sensations that tend to strike around bedtime. The American Academy of Sleep Medicine recommended in March 2024 to stop using dopamine-boosting drugs as first-line therapy for RLS; it should be taken only by patients whose symptoms don’t respond to other treatments.

A 2024 study suggests that having an attitude of gratitude may help people live longer.

A 2024 study suggested that walking regularly may help stave off repeat episodes of low back pain.

The way people’s bodies absorb and process medications changes as they age. This, along with additional health problems, muscle loss, or frailty, can make seniors more vulnerable to drug side effects and interactions. Adults 65 and older use more over-the-counter drugs than any other age group in the United States. Nonprescription drugs to reconsider include aspirin, nonsteroidal anti-inflammatory drugs, proton-pump inhibitors, and older types of antihistamines.

In addition to hallmark symptoms such as persistent sadness and apathy, depression can also trigger memory problems. People with depression may lack focus, leading to memory lapses. Depression may also alter brain chemicals that help people sustain attention. Memory problems in depression show up differently than in dementia, making people unable to retrieve long-term memories. Positive memories also fade first in depression because brain areas that process positive or rewarding experiences are disrupted.

Drinking is linked to increased risks of high blood pressure. Alcohol elevates levels of the hormone renin, which narrows blood vessels and decreases urine output. The more often someone drinks, the more likely high blood pressure will result.

A subconjunctival hemorrhage is a broken blood vessel in the eye. It’s usually not serious and resolves on its own within two weeks. People who also experience eye pain or vision changes may have an eye infection and should see a doctor.
