Attention-deficit/hyperactivity disorder or ADHD is a psychological disorder which usually manifests during childhood. It is something that not one parent would wish for his child, but it happens. As per Healthline, 6.1% of American children receive medication for ADHD. However, sometimes, a misdiagnosis may occur as the symptoms of ADHD is similar to some psychological issues like post-traumatic stress disorder. “While it is true that severe anxiety can sabotage attention, many of the youth in question here have struggles with both real anxiety and real attention problems,” David Rettew M.D. wrote.
