A 2024 study suggests that older adults who fall for financial scams may have brain changes associated with a higher risk of Alzheimer's disease.

Decreased concentration is often a normal part of aging as the brain's ability to function efficiently gradually declines. People who struggle with concentration when performing tasks can try strategies like avoiding multitasking, taking scheduled breaks, and removing distractions. Other lifestyle behaviors may also affect concentration and should be examined, such as sleep, medication, and caffeine intake. Activities like meditating, reading, and learning a new skill also can help improve mental focus.

Leg pain may be caused by deep-vein thrombosis (DVT), a blood clot that forms in a deep vein, usually in the leg. Left untreated, the clot may break off, travel to the lungs, and cause blockage in a lung artery, known as pulmonary embolism (PE), which can be life threatening. Diagnosis of DVT and PE may include a review of symptoms, a D-dimer blood test, a leg ultrasound, or a chest CT scan. Both conditions are most often treated with direct-acting oral anticoagulants.

Eating high amounts of processed red meat each day may increase the risk for future cognitive decline and dementia. Switching out processed red meat for nuts, legumes, low-fat dairy, chicken, or fish also may lower the risk.

Doctors are rethinking their recommendations about a supplement used to help slow dry age-related macular degeneration (AMD). They're advising people to keep taking the pill even when they reach the late stage of the disease. Previously, the supplement-a cocktail of antioxidant nutrients known as the AREDS2 formula-was believed to slow disease progression only in the beginning and intermediate stages of dry AMD. New evidence suggests the supplement might also slow vision loss in late-stage dry AMD.

There's no clear-cut answer about whether taking antihistamines for allergies increases dementia risk. Antihistamines have anticholinergic effects, which might increase the risk for dementia by blocking a particular brain neurotransmitter or increasing brain inflammation. But studies on whether there's any link between antihistamines and dementia have produced conflicting findings. Doctors advise taking the lowest antihistamine dose possible or using another medication for symptom relief.

Generalized itching is common and has many potential causes. Examples include skin changes that occur with age; skin conditions; and many other diseases such as diabetes, thyroid disease, kidney disease, and liver disease. Relief involves treating underlying conditions; using medications that ease itching; bathing with lukewarm rather than hot water; using soap only on the armpits, genitals, feet, and face; and moisturizing immediately after showering or bathing.
