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.

In May 2022, the FDA approved a blood test to help diagnose Alzheimer's disease. The test looks for amyloid-beta protein, a marker of Alzheimer's. The blood test is quite accurate, compared with positron emission tomography (PET) brain scans, which are more expensive and complicated. More blood tests, including some that look for tau protein (another marker of Alzheimer's), also are under development. Other tests used to diagnose Alzheimer's include computed tomography (CT), magnetic resonance imaging (MRI), and a spinal tap.

People taking antidepressants may have many reasons for wanting to discontinue the drug. They may feel they no longer need the medication or decide they cannot tolerate side effects.

Withdrawal symptoms can make the tapering process uncomfortable, but it's generally not dangerous.

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.

A review of studies published online April 13, 2022, by JAMA Psychiatry found that people who did 75 minutes per week of moderate-intensity exercise, such as brisk walking, had an 18% lower risk for depression, compared with people who didn't exercise.

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.
