Are all these new conditions for real ? ADHD, bipolar disorder, etc. etyc.?

I'm in my mid fifties and believe these do exist! It wasn't labeled when I was in school and there wasn't a way to deal with it as there is now! My son was diagnosed with ADHD and and after a great deal of consideration we finally tried Radilin! It made a huge difference imediately! it was like turning on a switch! His attention was not easily distracted and his grades came up drasticly! The only problem it affected his appotite! It did help him to get a hold on controlling his attention with only two or three years of use. I believe I had ADHD when I was in school and I am said to have what is called Bipolar disorder presently! So yes, I think these are real conditions!
