A new study says better heart health in middle age may help reduce a person's risk significantly for dementia later in life. Researchers at Sweden's Karolinska Institute studied 1,449 Finns enrolled in the Finnish Cardiovascular Risk Factors, Aging, and Dementia study. Adults with 'ideal' results on several cardiovascular health metrics were found to be 86% less likely to be diagnosed with dementia than those with lower scores. According to UPI, the metrics considered included smoking history, engagement in physical activity, body weight, cholesterol levels, and blood pressure. The findings suggest that maintaining lifelong heart health by not smoking, exercising regularly, and staying slim may reduce dementia risk later in life.
The US Centers for Disease Control and Prevention says up to 29% of all adults in the United States, or about 70 million people, have high cholesterol. In addition to lifestyle changes around diet and exercise, prescription statin drugs can help control high cholesterol, which is liked to cardiovascular disease. Now, a new study reveals older adults benefit from statins at least as much as young people in reducing the risk of heart attack, stroke, and heart disease. According to UPI, researchers say that for every 80 people age 80 to 100 who take statins, one heart attack will be prevented. In contrast, three times that number of people between ages 50 and 59 would need to take the drugs to prevent one heart attack. Similarly, a second analysis shows statins reduce the risk for heart attack and stroke in people over 75 by 26% for every one-point reduction in LDL cholesterol.

A new analysis from the US Centers for Disease Control and Prevention shows cancer can take years off a person's life--literally. UPI reports the analysis, released Thursday, says surviving cancer 'ages' a person's heart by up to nine years. Based on their overall health, adult male cancer survivors were found to have hearts that appeared 8 1/2 years older than their actual age. As for women, females who survived the disease were found to have hearts that appeared to be 6 1/2 years older. Past research has found that compared to non-cancer survivors, adult cancer survivors are at high risk for heart disease due to greater excess heart age.
It's been widely noted that survivors of the novel coronavirus COVID-19 may suffer neurological damage long after other symptoms survive. It's believed that this brain damage isn't caused by the virus, but rather by the body's immune response to it. Now, UPI reports an international group of researchers has called for studies to explore the potential long-term effects of COVID-19 on the brain. Previous studies have documented brain inflammation, or encephalitis, in patients with severe COVID-19 symptoms. Some patients also suffered strokes. Postmortem MRI scans of patients who have died from COVID-19 have revealed lesions, or damage, in different regions of the brain. Researchers say it's becoming clear that the damage done by COVID-19 may have chronic, long-term consequences that could impact patients' quality of life.
