Behavioural disorders
ADHD is sometimes refered to as a ‘disruptive’ or a ‘behavioural disorder’.
These disorders are those in which individuals (particularly young people) display disruptive (and often self-destructive) behaviour in multiple settings.
Other disruptive/behavioural disorders:
Oppositional defiant disorder
ODD is typically diagnosed around in the early school ages and tends to stop being diagnosed around adolescence. Young people with ODD have a well-established pattern of behavior problems. Symptoms include:
Being unusually angry and irritable
Frequently losing their temper
Being easily annoyed
Arguing with authority figures
Refusing to follow rules
Deliberately annoying people
Blaming others for mistakes
Being vindictive
All children can have these symptoms from time to time. What distinguishes ODD from normal oppositional behavior is how severe it is, and how long it has been going on for. A child with ODD will have had extreme behavior issues for at least six months.
Conduct disorders
The behaviour of a child with conduct disorder may depend on their age. Younger children (aged under 11) may repeatedly argue with, disobey and defy those looking after them. Older children with conduct disorder may consistently exhibit antisocial behaviour, such as:
being highly aggressive towards people and animals
stealing or damaging property
lying
fighting
violating rules
