ADHD
- A persistent pattern of inattention and/or hyperactivity-impulsivity symptoms that interferes with functioning or development.
- Several symptoms were present before the age of 12 years old.
- Several symptoms are present in two or more settings.
This differs from Treatment Resistant Depression because in that condition inattentive and/or hyperactivity-impulsivity symptoms are not the prominent symptomatology.
