When it comes to behaviour and ADHD, some people refer to the “three degrees” or 3 stages of ADHD.
The least troublesome is ADD, the Inattentive Type, then the Combined Type, and then finally the Hyperactive Type being the most disruptive.
The Inattentive Type is predominantly female. The lack of disruption is the primary reason why so many girls and women have slipped through the cracks when it comes to diagnosing the Inattentive Type
The next stage of behaviour severity is Oppositional Defiance Disorder. This where the person with ODD simply refuses to obey or follow instructions. I like to think of this as jabbing titanium high-heel spikes deep into concrete and refusing to budge.
The percentage of ADDers who have ODD is surprisingly high at 67%, by far the most common co-occurring behaviour.
Sitting on the apex of this behaviour-severity triangle is Conduct Disorder, CD. These children and young adults usually end up in reformatories, places of safety, youth detention centres, and prison.
Not only are people who have CD dangerous to others, they are dangerous to themselves, one of the reasons they are frequently removed from society. Again, the percentage of ADDers who have CD stands at 46%, just 2 percent above anxiety!
When asked an easy way to distinguish between the three, Dr Stephen Copps of the Georgia Medical Institute said this, “the ADHD child will forget what he has to do and disobey accidentally, the ODD child will refuse defiantly to follow instructions, while the CD child will deliberately damage property and inflict pain and destruction.”
