Making sense of dementia trends

Studies suggest that the world is facing two different dementia trends. One is that dementia rates are falling steadily in the United States and Europe. The other is that the number of dementia cases globally is rising, and will likely triple in the next 30 years, mostly due to population increases. People can try to reduce their dementia risk by adopting a healthy lifestyle that includes lots of exercise, a healthy diet, at least seven hours of sleep per night, limited alcohol consumption, socializing, improved balance, stress management, smoking cessation, and control of underlying health conditions.

Worry and anxiety linked to higher heart risk in men

Middle-aged men who often feel worried or anxious may be more prone to problems that raise heart disease risk as they age compared with their less-worried peers.

Scroll smarter to protect your mental health

Research has found associations between social media use and negative mental health effects in both youth and adults. These ill effects may reflect the particular ways people use social media. People may have a healthier online experience if they focus on interacting with others, rather than just scrolling through posts. Some additional strategies that can help improve the experience are avoiding posts from unpleasant people, discussing contentious subjects in person rather than online, and using social media to enhance real-life relationships.

New details about loneliness and dementia risk

A 2020 study found that people defined as lonely had a higher risk of dementia than those who were not considered lonely. Loneliness also was associated with smaller brain sizes and poorer executive function (the ability to plan, focus attention, and remember instructions).

What is alopecia areata and how is it managed?

Hair loss is a common problem for many men and women, but what does it mean to have alopecia? Alopecia areata occurs when the body's immune system attacks hair follicles, resulting in hair loss. AA can affect the scalp, eyebrows, eyelashes, or anywhere hair grows on the body.

Eating disorders spike among children and teens: What parents should know

A notable rise in eating disorders is particularly marked among adolescent girls. Many kinds of eating disorders can affect children and teens, and parents need to understand their causes and be aware of signs suggesting their child may have an eating disorder.

Primary progressive aphasia involves many losses: Here's what you need to know

When thinking about progressive brain disorders that cause dementia, you'd probably think of memory problems. But sometimes language problems, also known as aphasia, are the first symptom. There are different variants of aphasia depending on what aspect of language is disrupted, and they are caused by different diseases.

Could cataract surgery bring brain benefits?

A 2021 study found that people who underwent cataract surgery (a procedure replace the lens of the eye) appeared to have a lower risk of developing dementia than those who had cataracts but did not undergo surgery.

Even light physical activity may help prevent dementia

Past research shows that exercise may help to prevent dementia. A new study found that this may be true even for people who only do light daily activity, such as errands or housework. People who got only a little exercise still had a lower risk of dementia than those who were inactive. The risk reduction, however, was not as large as that seen in people who exercised more. Adding small daily bouts of activity may still make a difference when it comes to brain health.

The worst habits for your brain

Many habits can contribute to poor brain health, but four areas can have the most influence. They are the four S's: sitting, socializing, sleep, and stress. Research has found that poor habits in these areas can affect cognitive skills like memory, learning, and problem solving, and are linked to a higher risk of cognitive decline and Alzheimer's disease. Adopting simple lifestyle changes may help.
