Viagra may improve brain functions, prevent dementia: Oxford Study
Sildenafil, widely known by its brand name Viagra, may offer benefits beyond treating erectile dysfunction. Recent research suggests it can help prevent memory-related problems by increasing cerebral blood flow and enhancing blood vessel function in those at risk of vascular dementia. This finding is reported by Anuja Jaiswal in The Times of India (TOI).
Vascular dementia impacts cognitive functions like memory, reasoning, and judgment due to reduced blood supply to the brain, damaging brain tissue. Unlike Alzheimer's disease, where amyloid beta plaques block neuron connectivity, vascular dementia arises from obstructions in blood vessels leading to brain cell damage.

Why stop watching so much TV? It affects how you age, new study says
Swapping TV time for physical activity might not sound like the most enjoyable trade, but it is linked to significantly better chances of healthy aging, according to a new study. The research, led by Dr. Molin Wang from Harvard's T.H. Chan School of Public Health, emphasizes the benefits of replacing sedentary behaviors with light physical activity, moderate-to-vigorous physical activity, and adequate sleep.
The study analyzed data from over 45,000 participants of the Nurses’ Health Study who were 50 or older in 1992 and free of chronic disease. Over 20 years, researchers tracked their sitting habits, physical activity, and aging outcomes. Healthy aging was defined as living to at least 70 years old without major chronic disease and maintaining good memory, physical health, and mental health.
