12
Q
How is ADHD managed?
A
Conservative:
- Education on ADHD impact
- Parenting strategies - involvement from both parents
- Liason for school, college, uni
- Behaviour management strategies
Pharmacological: - stimulants!!
- 5+ and young people
- 1st line = methylphenidate
- Low starting dose
- Titrate dose against behaviour + school work
- 2nd line = lisdexamfetamine
- If 6-week trial of methylphenidate at therapeutic dose did’t work
- Consider dexamfetamine IF responding to lisdexamfetamine but don’t tolerate long effect profile
- 1st line = methylphenidate
- Adults:
- 1st line = methylphenidate or lisdexamfetamine
- Try the other if the 1st didn’t work
- Consider dexamfetamine IF responding to lisdexamfetamine but don’t tolerate long effect profile
- 1st line = methylphenidate or lisdexamfetamine
13
Q
How is autism managed?
A
Conservative:
-
Psychotherapy - both parents + patients:
- CBT
- Behaviour management programmes
- Applied behavioural analysis program - intense program (40hr a week for 3yrs) based on operant conditioning, imitation and reinforcement
-
Social - led by functional assessment:
- Carers
- Respite care
- Education of peers in school
- Learning support / special schools
Pharmacological:
-
2nd gen anti-psychotics = 1st line for children + adolescents with ASD
- Risperidone (only one liscenced in UK) - for aggressive, challenging behaviour in autistic children
- SSRIs - low dose, used for restricted repetitive behaviours (evidence limited)
- Melatonin - ↓ sleep latency (time taken to fall alseep)
