  1. Family: education on ADHD; advice on parenting
    and boundaries. eg info leaflets.

  3. Support for teachers: appropriate schooling placement.
  4. Family therapy. parents may want to discuss diet of child; some evidence.
  5. Stimulant medication (methylphenidate - 1st line drug NICE - severe cases)

lisdexamphetamine - 2nd line drug if methylphenidate not working well
dexamphetamine - if lisdex was good but intolerable side effects

3rd line drug - Atomoxetine - non-stimulant medication
- 1st line if tics

others;
clonidine - 1st line if comorbid tics - tertiary adhd service must advise.

Concerta XL - long acting methylphenidate for 1x daily use

This increases monoamine pathway activity, improving concentration and allowing learning and maturation.
