What is ODD?
Oppositional defiant disorder (ODD) is a childhood disorder that is defined by a pattern of hostile, disobedient, and defiant behaviors directed at adults or other authority figures.
ODD is also characterized by children displaying angry and irritable moods, as well as argumentative and vindictive behaviors.
Some people consider ODD a precursor to CD with reportedly 60% of children the CD meeting diagnostic criteria for ODD; persistent fighting is thought to be a marker of progression of ODD to CD but should be considered separate diagnostic entities.
Is CD more prevalent in males or females?
Males
Males = 9.9% Females = 3.5%
Prevalence in UK = 6.6%
According to Moffit, what are the two types of Conduct Disorder?
Lifecourse persistent offenders
Adolescent limited offenders
Life course persistent offenders -start early and continue their behaviour.
Adolescent limited group who become influenced by social issues and peers. Their behaviours stops when they get more adult roles.
Moffitt suggests that there is something fundamentally different about the life course persistent group in terms of affect, and cognition.

Childhood Onset (i.e. Life Course Persistent Offenders
What is the observed heretability estimate for early onset antisocial behaviour?
(Asreneault et al, 2003 study)
82%
What structural brain differences have been reported in people with conduct disorder? (2+)
Overall brain volume reduction
Significantly reduced grey matter in anterior insula bilaterally
Other areas significantly reduced: Left inferior frontal gyrus Middle frontal gyrus Left amygadal Right parahippocampus Fusiform gyrus Cingualte gyrus Right caudate
What difference in brain functioning have been reported in people with CD? (2)
Increased response in left side amygdala to negative pictures.
CInualate and temporal- parietal under-activation
What pre-natal aetiological factors have been linked to developing CD? (2)
Maternal Smoking (most strongly linked)
Maternal alcohol (not a strong associated factor) (more in first trimester than others)
Which peri-natal aetiological factor has been linked to developing ADHD?
Low birth weight
