The important thing to understand is the "yet". Unfortunately, there is still so much we do not understand about the human brain, so when people seem "different" we deem them as
"disordered", and I agree, that isn't really helpful.

As we continue to understand why people experience different challenges, it will end up slowly becoming something society in general will slowly learn to understand better too.

This information I provided took a lot of time to study and finally understand PTS better and see the difference in what a person who struggles with PTS has to deal with verses someone who expresses similar symptoms but is not challenged with PTS, but instead something different.
