The Trajectory of the Undiagnosed ADHD Teen*
Over the last 13 years working with teens, Ive noticed a pattern. I often received referrals from PhP, IOP, and residential programs for teens that have been in treatment for years.
When exploring when, how and why things started for them, we have landed on this pattern. Yet, rarely have any often been assessed for a neurodevelopemental difference. Today Im focusing just on ADHD.
4th grade - Anxiety peaks
5th grade- Self esteem decreases
6th grade - Depression sets in
7th grade- SH and Eds begin
8th grade - Thoughts of SI
9th grade - Crash
10th grade - Disengaged
11th grade - Change to school structure
12th grade- Panic about future and loss of childhood.
This is not an absolute rule, or diagnostic in and of itself. Ages, grades, and intensity will vary for everyone, and much of this can and will appear with other diagnosis.
Familiarity with this trajectory is key for greater understanding of identifying and supporting ADHD brains and not just treating Anxiety and Depression without digging deeper.
How does this line up with your experience? Or with what you see in your practice?
