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.
Gizmodo reports certain bacteria spread by cat scratches and other animal exposures can sometimes have a dramatic impact on the brain. A new study profiles a group of patients with psychiatric illness who simultaneously showed signs of infection from bacteria called Bartonella. Bartonella bacteria aren’t usually linked to serious illness in people. But certain groups, like those immunocompromised, might be more vulnerable generally. The rod-shaped Bartonella bacteria can survive and replicate inside other cells, much like viruses. This ability allows them to evade conventional tests for detecting infection and makes it harder for antibiotics to kill them. Bartonella henselae is the most commonly seen infection in humans and causes cat scratch disease--also called cat scratch fever. Despite the name, B. henselae and other disease-causing Bartonella can be spread through dogs and other mammals, and parasites like ticks, fleas, and lice. I
A new study reveals older women have a greater risk of heart failure if they spend more time sitting than those who sit less. And according to UPI, that's even if they have a regular fitness routine. As part of the Women's Health Initiative Observational Study, researchers analyzed the records of 80,100 postmenopausal women who were roughly 63 years old. Women spending less than 6.5 hours daily sitting or lying down had 15% less risk of heart failure hospitalization than women spending 9.5 sedentary hours daily. The data also showed the less sedentary women had a 42% less risk of heart failure hospitalization than women reporting more than 9.5 hours sedentary hours.
