Science has shown that when people multitask, they become more easily distracted and less productive, score lower on tests for recalling information, and make more errors. Older adults especially struggle with multitasking because aging brains have more trouble blocking distractions. The solution is to monotask by focusing on only one job until it's completed. Methods for monotasking include prioritizing tasks, blocking distractions, and working in intervals.

A randomized trial published May 14, 2022, in The Lancet found that people with heart disease who ate a Mediterranean diet for seven years had a 26% lower risk of having a heart attack or stroke, compared with people who ate a low-fat diet.

It can be hard to detect a potentially serious type of memory loss in a loved one, especially if small cognitive changes occur over time. It may help to note memory slips that happen consistently or those that seem uncharacteristic for the person. Tracking incidents on a calendar may also help reveal patterns. Potential incidents include consistently forgetting a close family member's name, important conversations, words for everyday objects, bills that are due, medication times or doses, or routes home from familiar places. Other common issues are frequently having trouble at work, making financial mistakes, or taking medications incorrectly.

Humans' relationship with music is complex and individual, and there are times when music can have a clear and immediate impact on our well-being. Music therapy uses music as a therapeutic tool to address certain health care goals.

A 2022 study found that people who have depression after a heart attack are nearly 50% more likely to suffer a stroke compared with heart attack survivors who don't develop depression.

About one in 11 men ages 65 and older has atrial fibrillation (afib), a heart rhythm disorder that causes an irregular and often faster-than-normal heartbeat. Afib can be persistent and chronic, or it can happen intermittently. People might have no symptoms with either variety, or afib can cause lightheadedness, shortness of breath, chest pain, or extreme fatigue. But the biggest worry is a fivefold increased risk of stroke. The main treatment choices for people are rate control with medication, or rhythm control, done with medication or a procedure such as electrical cardioversion or catheter ablation.

Brain damage can cause the language disorder aphasia. It affects a person's ability to understand or produce speech. Coping with aphasia requires treatment for the underlying cause and speech therapy to learn how to communicate despite language deficits. If the cause of the aphasia improves, so may the aphasia. But many people will continue to live with some level of aphasia, especially if the cause of brain damage is a progressive disease, such as Alzheimer's.

COVID survivors—even those with mild infections—appear to face a higher risk of cardiovascular problems such as heart failure, heart attack, and stroke for up to one year after their initial infection. People who were hospitalized (especially those who ended up in the intensive care unit) may have the highest risk. The virus that causes COVID can injure blood vessels and triggers an immune response that promotes the formation of blood clots in arteries and veins throughout the body and brain.

Seasonal affective disorder, or SAD, is less common in summer, but a seasonal pattern of depressive symptoms can occur despite exposure to many hours of daylight. Many summertime SAD symptoms resemble overall depression markers, but eating and sleeping patterns can deviate. People can combat summertime SAD by sticking with antidepressants and psychotherapy, maintaining routines, exercising, and taking a break from social media.

As discussion and debate continues on mass shootings there is increasing evidence that growing up amidst this violence and other extreme stressors affect developing brains and bodies in ways that can be permanent.
