As a child, I was frequently misdiagnosed with Asperger Syndrome. When I was in the hospital for SI, the psychiatrist on call also "diagnosed" me with that. When I was actually in the psych ward, my team of psychologists laughed at that diagnosis because it's clearly incorrect. The thing about all of the "professionals" who would diagnosis me with Asperger Syndrome is that they would always ALWAYS make that call within the first ten minutes of meeting me. I remember quite vividly when I was 12 going to a psychologist and I said one sentence to her and she replied with "yeah I can already tell you have Aspergers" because of the vocabulary I used.

People also overlook my hyperactive tendencies. I don't know why. My official diagnosis is inattentive ADD "with ticks" but my current psychiatrist/therapist strongly suspect I actually have ADHD with both inattentive and hyperactive tendencies. I talk really fast while sometimes interrupting people, I absolutely never sit still, and I am constantly fidgeting.

I think they do this because there is this strange commonly held belief that ADHD is a childhood diagnosis and that people outgrow it. I think it's an over diagnosed condition in children and that's why it appears as if people outgrow it
