Researchers say people's blood pressure control has not improved over recent years, and those high numbers could lead to a higher risk of a stroke. A study led by the University of Michigan Health finds those years of high systolic blood pressure—that's the top number on the blood pressure reading—significantly increase an adult's risk of having the two most common types of stroke. In fact, for every 10 points higher, the risk of ischemic stroke goes up 20% and the risk of brain hemorrhage increases by 30 percent. The physician who led the study says it's essential to get ahead of this condition.

September is World Alzheimer’s Month. And recently, two new risk factors for the disease were identified. Dr. Caldwell said they’re not entirely sure why these two health issues could play a role in a person’s risk for Alzheimer’s. However, it’s possible vision loss could impact a person’s sensory input, meaning their brain is not processing as much information. Vision loss could also make it harder for an individual to exercise, socialize with family and friends, or do other stimulating activities. As for those with high levels of LDL cholesterol, Dr. Caldwell explains that it’s not good for our heart and blood vessels. Our brain has a lot of small blood vessels, so they can be more easily impacted by things like cholesterol.
