Mental issues, including anxiety, depression, and OCD, also become more frequent in people of all age groups. Actually, in their 20s people have the highest sub-clinical depression rates. A situation with older people is even sadder, as dementia becomes one of the most widespread issues of that age. Maybe, mental health apps are not a total solution. But they can help dementia patients a lot, especially combined with other activities. They track the well-being of users, reduce anxiety, and increase personal safety.
