child and adolescents

Order Description
Basically I have done the introduction myself and someone else has done the pathophysiology (600 words). If you could please go over those 2 first and correct whatever does not sound right or english as I am not too impressed with either of those components. It does not need to be completely changed as the research has been done already just corrected 🙂
I will also attach what is expected for the rest of my assignment in my account.
