Six out of ten of the young people had ADHD either diagnosed or suspected. Three of those diagnosed were unmedicated. Other learning difficulties among the cohort also included auditory processing challenges for example.
Mental health issues were noted for several young people including difficulty regulating emotions, anxiety, suicidality and PTSD. Almost all had substance abuse noted in their assessments.
OK, there were ten people. One killed in a vehicle collision, one kicked out, one ran away.
Using a percentage is misleading.
