Patient: My 8 yr old son was assessed for adhd. the result was there wasnt enough evidence to suggest he had it, although certain things stood out in the exam. today however the doctor has prescribed him medikinet 5mg. i asked if these help will he then be diagnosed with adhd to which she said no she doesnt think he has it. why would this drug be prescribed if she didnt think he had adhd?

Doctor:
