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.

Sex, drugs, and depression: What your doctor needs to know

For many people, a visit to the doctor causes anxiety, and discussing sensitive subjects like sexual problems, substance use, or mental health issues is even more likely to induce discomfort. But these discussions can be less anxiety-inducing and more productive if people know what to expect.

Brain fog: Memory and attention after COVID-19

Brain fog, meaning slow or sluggish thinking, can occur under many different circumstances. In many cases, it is temporary and gets better on its own. Many people who have recovered from COVID-19 report some degree of brain fog and a study suggests even those with milder cases may experience problems with memory and attention.

The care that transgender youth need and deserve

Some people feel very strongly that their gender is not the one they were assigned at birth. When families, health care providers, and others ignore or deny this, or try to stop the person from living as the gender they feel is right for them, it's not only unkind but dangerous.
