Poor sleep is linked to high blood pressure, diabetes, obesity, and heart disease. Now a study published in Neurology Dec. 10, 2014, suggests that people with conditions that rob them of oxygen and deep sleep are more likely to have changes in the brain that may lead to dementia. Researchers say conditions such as emphysema and sleep apnea reduce the amount of oxygen in the blood during sleep, which can lead to silent, undetectable "ministrokes." Researchers also found that people who spend less time in deep sleep, called slow-wave sleep, are more likely to have loss of brain cells than people who spend more time in slow-wave sleep. Slow-wave sleep is important in processing new memories and remembering facts. The researchers noted that past evidence has shown that using a continuous positive airway pressure (CPAP) machine for obstructive sleep apnea may improve cognition, even after dementia has developed. "Sleep quantity and quality are important to maintain optimal health and prevent disease," says sleep expert Dr. Lawrence Epstein, an instructor in medicine at Harvard Medical School. "By getting enough sleep, you ensure that you are getting all the types of sleep, which is necessary to maintain proper functioning." 

Well-educated people who report memory problems may face a higher risk of stroke.

Minor memory slips—such as losing your keys or forgetting an acquaintance's name—are common as we age. However, people who express concern about their memory may have a heightened risk of stroke, particularly if they're highly educated, according to a study in the January 2015 Stroke.

Mindfulness has garnered tremendous interest over the past decade. Research suggests that mindfulness — the ability to live each moment as it unfolds and accept it without judgment — can help reduce stress and enhance health.

Perhaps one of the greatest psychological benefits of interacting with a dog is the opportunity it provides to be more mindful — to purposely focus your attention on the present moment.

The most conclusive evidence shows that combining activities that benefit body and soul also reduces the risk of dementia.

Q. I took a low dose of the antidepressant desipramine for more than two years for chronic pain. Once I started physical therapy, my pain improved so much that I quickly tapered off the medication. I have been off of it for a month now, but am still experiencing "discontinuation symptoms." I can't sleep well and feel a little dizzy. What can I do for this?

A. It can be liberating to realize that you no longer need to take a medication. However, sometimes you can't just throw your pills away. There are many medications (both psychoactive and otherwise) that require you to taper off slowly when it's time to stop them. Stopping such a medication too quickly will cause what are called rebound side effects. Desipramine (Norpramin) is a tricyclic antidepressant, one of the drug categories that require a slow taper.

Goal setting and relaxation techniques reduce stress and ease the physical and emotional burden
it can take.

Diet and exercise are only part of it. Add heart health and staying mentally and socially active to keep your mind and memory sharp.
