Q

Why is birth history important to consider when assessing development?

A

Milestones should be corrected for age eg. 2 months preterm - expect milestones 2 months later
Complications at birth can affect development eg. HIE and CP

Q

Explain the diagnosis of ADHD and the management as if to a parent (in a GP setting)

A
  • From what you have described, I think your child may have a condition called ADHD
  • Have you heard of this before? What do you think?
  • ADHD is a common condition, and means that your child has difficulty with maintaining attention as well as being over-energetic, which is causing problems at home + school
  • While this may be the case, there may be other explanations for their behaviour. The first thing we do when we think a child might have ADHD is to watch and wait for 10 weeks. I’ll also refer you to an ADHD support group for parents, which can help you to talk to others going through similar things and get more info, as well as learn some parenting techniques
  • In 10 weeks, we’ll review how things have gone and if there are still problems, we’ll refer you to a specialist who will be able to make a diagnosis and advise on how to manage
