[Instant Help From 9$/Pg] One Statement Caught
Good start to the discussion. For your RQ, one statement caught my attention: “With all the above research, there is no correlation in a study on the age limit for diagnosing ADHD”. You could make this your hypothesis and it would much easier to do then having an intervention (especially with medicine).
Is there a correlation between age of diagnosis and severity of ADHD symptoms in adulthood? This would let you directly correlate age (which sounds like the gap) and you can avoid the problems with interventions and children because you would be asking adults.
