Not everyone "grew out of being shy". I know quite shy adults and shy old people. I also know anxious adults and old people. I kind of wish they had treatment back then, because some aspects of my life would be better if they would get therapy. Not having names for issues does not help at all. It just makes it hard to impossible to describe to others what is going on and get reasonable advice. And in the first place, it makes it hard to impossible to know it does not have to be that way.
Literally from the article:
> researchers found that the prevalence rate of neurological diseases and disorders has remained stable over time, with only a 0.2% decrease between 1990 and 2021. Over the same period, deaths from neurological diseases and disorders declined by 15%, meaning more people are living longer with these conditions. As a result, the number of years lived with disability increased by 10%.
