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.

What exactly is a hernia?

A hernia is an area of weakness in the abdominal wall muscles that allows contents of the abdomen to push through the wall and form a pouch. A small hernia may follow a "watch and wait" approach, while a larger and more painful one often requires surgery to repair.

Which disease starts first?

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

Are toxins flushed out of the brain during sleep?

The glymphatic system is the brain's "waste management" system. It carries fresh fluid into the brain, mixes the fresh fluid with waste-filled fluid surrounding brain cells, and flushes the mix out of the brain and into the blood.

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.

Thoughts on optimism

Science continues to find that people with an optimistic outlook enjoy healthier and longer lives. The power of optimism is not just having a sunny disposition, but applying this mindset to make positive change. Even if people are not naturally optimistic, there are ways to change one’s outlook, such as looking for opportunities during trying times, focusing on personal strengths, practicing gratitude, and visualizing their best possible self.

Pick up the pace for better walking with peripheral artery disease

A small, randomized trial published online April 6, 2021, by JAMA found that people who took part in a high-intensity walking program for one year covered more ground in six minutes than people who’d taken part in a low-intensity walking program.

Man's best friend — and medicine's too?

Scientists are studying whether medical detection dogs can sniff out and identify disease in humans, such as cancer, infection, and Parkinson’s disease. Dogs might be useful because their noses have 60 times the number of scent receptors as human noses; that might make dogs able to detect scents given off by bacteria or diseased human cells. But it’s hard to get solid evidence about the accuracy of medical detection dogs. Scientists are also studying whether technology can replicate the same kind of detection.

Easing summer swelling

Lower leg and foot swelling is most often the result of an abnormal buildup of fluid, which doctors refer to as edema. Fluid tends to flow downhill, making it more likely to pool in the lower parts of the body. Excess fluid retention can be triggered by many things, including eating too much salt, heat, drinking alcohol, or standing for a long period of time. To reduce it, reduce dietary sodium, elevate the feet at the end of the day and wear support stockings.
