Take a moment to be mindful
Mindfulness is the practice of purposely focusing your attention on the present moment, such as how the air smells and feels as you walk your dog, or how a bite of bread tastes with dinner. The ultimate goal is to help shift your thoughts away from your usual preoccupations toward an appreciation of the moment and a larger perspective on life.
Scientific examination of mindfulness shows that it can improve both physical and psychological symptoms and create positive changes in health attitudes and behaviors.
Vigorous exercise may counter cognitive decline in early Alzheimer's
Reports at the Alzheimer's Association International Conference in July 2015 verified that women are at higher risk than men for developing Alzheimer's, and also progress more rapidly from mild cognitive impairment to out-right dementia than men do. But not all the news was bad. A study reported at the meeting indicates that physical exercise can halt, and even reverse, the decline in people with mild cognitive impairment.
In that study, conducted by researchers at Wake Forest University in North Carolina, 65 previously sedentary women and men with mild cognitive impairment exercised at peak capacity for at least 45 minutes four times a week for six months. At the beginning and end of the study, researchers tested participants' cognitive skills and examined their blood and cerebrospinal fluid for levels of tau protein—a principal component of the amyloid plaques associated with Alzheimer's disease. They found that the participants scored significantly higher on the cognitive tests at the end of the study than they had at the beginning. Their tau protein levels had declined substantially as well.
Exercise: A promising treatment for dementia?

We know that moderate-intensity exercise, such as brisk walking, can both improve thinking skills and slow their decline in older age. Now a trio of studies presented at the July 2015 Alzheimer's Association International Conference suggest that aerobic exercise may even be able to help protect your brain from Alzheimer's and other dementias, and improve your quality of life if you have the disease. One study of 200 adults with Alzheimer's showed that those who engaged in three hour-long exercise sessions a week for 16 weeks had less anxiety, irritability, and depression and better mental speed and attention compared with those who didn't exercise. A study of 65 sedentary older adults with mild cognitive impairment showed that those who took part in 45 to 60 minutes of aerobic exercise four times a week for six months not only had better attention and planning skills, but also better blood flow to the brain and a reduction in dangerous proteins associated with Alzheimer's disease, compared with those who only did stretching exercises. A study of 71 older adults with cognitive impairment due to vascular disease found that those who did an hour of aerobic exercise three times per week for six months improved their thinking skills, memory, and attention compared with those who did not exercise. Although the studies were presented at a scientific meeting, it's only after publication of the full details that scientists can adequately judge a work. Nevertheless, the studies are in line with past research showing that regular exercise may help protect the brain.
Savor the gifts of the aging mind

With aging, the body and mind change—but it's not all bad.
Aging brings physical changes and a greater risk of health problems—no one needs to tell you that. The mind changes too, and we grumble about things like increased forgetfulness. But the aging mind bestows some gifts, too.
Easing grief through religion and spirituality
There are many different ways to find comfort when grieving. Some people find that spirituality or organized religion is a source of great solace. Specific rituals and rites — whether sitting shiva, setting up an altar inside your home, or gathering at the cemetery once a year — can draw people together and encourage them to share their grief. Attending religious services can link you with a well-defined community primed to offer help of all sorts. And a kind word, a willing listener, a shared meal, and any number of large and small acts of assistance help keep people afloat and ease their distress after a death.
Religious or spiritual beliefs may also help by lending larger meaning to a loved one's life and death. For some, the belief that a loved one is enjoying the spiritual riches of heaven or preparing for the next turn of the wheel through reincarnation can be comforting. Believing your loved one helps guide you in this world or that you will be reunited in another place after your own death can help you continue to feel connected with the person.
Exercise is an effective stress-buster
If exercise were available as a pill, experts say, everyone would be taking it. One reason is that exercise is very good at defusing stress. If you exercise — especially right when the stress response is triggered — you burn off stress hormones just as nature intended, instead of letting them pile up.
What's more, just about any form of motion on a regular basis helps relieve pent-up tension. Rhythmic, repetitive movements, such as walking, running, swimming, bicycling, and rowing — and specific types of exercise such as yoga, tai chi, and qigong — actually elicit the relaxation response, too. Regularly engaging in these kinds of activities can help you ward off everyday stress.
Use everyday habits to keep your memory in good shape
Your daily habits and lifestyle — what you eat and drink, whether you exercise, how stressed you are, and more — affect your mental health every bit as much as your physical health. A growing body of research indicates that regular exercise and a healthful diet can help protect your memory from aging-related decline.
Exercise
Physical fitness and mental fitness go together. People who exercise regularly tend to stay mentally sharp into their 70s, 80s, and beyond. Although the precise "dose" of exercise isn't known, research suggests that the exercise should be moderate to vigorous and regular. Examples of moderate exercise include brisk walking, stationary bicycling, water aerobics, and competitive table tennis. Vigorous activities include jogging, high-impact aerobic dancing, square dancing, and tennis.
Depression and illness: Chicken or egg?

When depression strikes, doctors usually probe what's going on in the mind and brain first. But it's also important to check what's going on in the body, since certain medical problems are linked to mood disturbances. In fact, medical illnesses — and medication side effects — may be behind nearly 10% to 15% of all cases of depression.
It's not uncommon for a physical illness to trigger depression. Up to half of heart attack survivors and those with cancer report feeling blue, and many are diagnosed with depression. Many people who have diabetes, Parkinson's, or other chronic conditions become depressed.
Is thyroid hormone causing my recent mood changes?
Ask the doctor
Q. Recently, I felt very agitated and out of control, crying and angry about things I could ordinarily handle with ease. I was starting fights with my husband and others over relatively insignificant issues. I had been taking synthetic thyroid hormone for several decades and had very low levels of thyroid-stimulating hormone in my blood. I've stopped taking the hormone and feel better, but I feel bad about the way I snapped at my friends and family. Could thyroid hormone have been to blame for my behavior?
A. It could very well have been responsible. Low thyroid-stimulating hormone (TSH) levels mean that thyroid hormone levels are increasing. Anxiety, agitation, and restlessness are all signs of hyperthyroidism—an overactive thyroid gland or, in your case, too much thyroid hormone medication. You can let your husband and friends know that your irritability was probably caused by too high a dose of your prescription and not a permanent change in your disposition.
