Migraines linked to high blood pressure after menopause

Women with migraine headaches may be more likely to develop high blood pressure after menopause.

Reducing heart risks in the wake of breast cancer treatment

Hormone therapy is a highly successful breast cancer treatment for women, but it can elevate cardiovascular risk. Women can reduce those risks by being vigilant about their heart health and working closely with their doctors. Women who have taken or are taking these medications as part of breast cancer treatment should focus on adopting a healthy lifestyle, exercising regularly, and keeping close tabs on their blood pressure, cholesterol levels, and blood sugar levels.

Look inside your heart

The traditional measures to gauge heart disease risk don’t always tell the whole story. Sometimes more medical information is needed. An increasingly used test to predict a person’s risk for heart attack or stroke is a coronary artery calcium scan. It measures the amount of calcified plaque in the heart’s arteries, high levels of which suggest higher overall plaque buildup. The number can determine if people should begin statin therapy and make additional lifestyle changes.

The book of neurogenesis

The brain can continue to produce new neurons as people age, even late into life, through a process called neurogenesis. Right now, scientists are looking at why neurogenesis especially happens in the hippocampus, the region responsible for learning information and storing memories. Animal studies have shown that regular aerobic exercise is associated with an increased production of neurons in the hippocampus. If the same is true in humans, it may be the reason for the observed link between physical activity and maintaining cognitive fitness, and perhaps a lower risk of dementia.

Screening for atrial fibrillation: An update

Atrial fibrillation (afib), an often-silent heart rhythm disorder, increases the risk of stroke. Early detection may enable people to start taking anti-clotting drugs to prevent a stroke. Current afib screening methods include asking people about afib symptoms and taking an electrocardiogram during routine check-ups. Wearable devices such as smart watches and fitness trackers can detect afib, but they aren’t yet accurate enough to be used for widespread screening.

A new Alzheimer's drug has been approved. But should you take it?

The FDA has granted accelerated approval to the first new drug in nearly two decades for Alzheimer's disease. But there are potential side effects, and results of studies of this drug have been mixed. It is not yet known whether the drug truly works, or how effective it will be, so the approval is contingent on the drug's maker conducting further studies over the next several years.

What's the relationship between diabetes and dementia?

It has been known for many years that type 2 diabetes increases a person’s risk for stroke and heart disease, and more recent studies have shown that diabetes also increases risk of dementia. But new research examined the association between when a person first is diagnosed with diabetes and their risk of developing dementia later.

Which disease starts first?

Among atherosclerosis, obesity, high blood pressure, high cholesterol, and diabetes, which are all related, cholesterol deposits start first.

Do I need to take my blood pressure in both arms?

Taking blood pressure readings in both arms can help reveal potential heart risks.

Sleeping five hours or less may raise dementia risk

Adults ages 65 and older who sleep less than five hours per night have almost double the risk of being diagnosed with dementia compared with those who sleep the recommended seven to nine hours.
