Brain development in children and adolescents: Insights from anatomical magnetic resonance imaging
Rhoshel K. Lenroota and Jay N. Giedd (2006)
Yates, Williams et al. 2006, JNNP: anatomical magnetic resonance imaging
Attendance rates for moderate to severe head injury per
100 000 population for each 5 year age band by sex and area residence (GCS under 12).
Nb. Rates of TBI (across all severities) in males across severities are given as between 5% to 24%
250-450 per 100,000 across all severities (US/UK) - 80% approx are MILD
Brain Areas that typically Injured… anatomical magnetic resonance imaging
“poor anger management (irritability and impulse control are common” (Hawley et al. 2003)
Problems: Attention, working memory, executive control disinhibition etc.
lack of “moral” reasoning.
(Damasio 1996; Anderson, Bechara, Damasio, Tranel, & Damasio, 1999; Hanks, Temkin, Machamer & Dikmen 1999; Levin & Hanten, Powell, 2004).
Often there is inappropriate social behaviour
the most common and disruptive issue (Henry, Phillips, Crawford, Theodorou & Summers, 2006).
may not be evident until adolescence (Lishman, 1998; Teichner & Golden, 2000)
point at which ‘delayed costs’ of earlier ABI are expressed (see Anderson 2008 re: neuroplasticity & crowding effects)
may occur in isolation from cognitive deficits (Anderson, Northam, Hendy & Wrennall, 2001
persisting personality and emotional deficits – due to de-coupling of cognition and emotion - has been described by Damasio (1994), as “acquired sociopathy”” –
Max et al, 2001: prospective study of 94 children with TBI aged 9 at time of injury
OPC in 57% of severe TBI sample (22/37) & 5% mTBI (3/57)
labile and aggressive OPC subtypes most common - 3-4 x more
Problems MIGHT also occur post MTBI anatomical magnetic resonance imaging
Wrightson, McGinn and Gronwall (1995)
Limond et al. 2009
follow up of moderate-severe and (mostly) complicated MTBI showed persisting disabilities at 1 year –

Theory of Mind (ToM):
Emotion reading skills are developed across the span of childhood into late adolesecence.
From birth Intrinsic bipolar emotional related to arousal - distress and pleasure (Schaffer, 2003).
6? months - primary emotions - surprise, interest, anger, sadness and fear
From 1 yr Girls ‘empathising’ , by 3 Theory of Mind - boys slightly later
By 7-9 Complex theory of mind (e.g. Detecting faux pas) (see Baron-Cohen et al, 1999).
Continues to develop in late adolescence (14-17 yrs (ToM) (Dumontheil et al in press)
Development is non-linear - rapid development associated with growth of the prefrontal cortex, (see Tonks et al. 2009)
We were both, in our own way, manipulators — good at grasping the feelings of others and instinctively playing on them.

positive peer relationships are an essential component of well-being
social isolation from peers poses a considerable threat to children’s mental health in both the short and long-term (Guralnick, 2006).
absence of peer relationships undermines self-esteem and deprives children of important pleasurable experiences, contributing to depression Windle (1992)

192 young male offenders ranging from 11 to 19 years of age (M = 16.63, SD = 1.07 years) (response rate of 98%).
The mean number of convictions 6.95 (SD 4.56).
Offences of violence accounted: 27.1%
shoplifting, theft, and robbery: 25.5%
drug offences: 11.6%
Williams, Cordan et al (in press, Neuropsychological Rehabilitation):
65% reported a history of “head injury”
main category of injury was violence (57.6%)
With falls “on drugs” being second most common “criminal cause”.
MTBI with a LOC of up to 10 minutes & Moderate - severe TBI made up 46% of the overall sample.
Repeated MTBI were also very frequent
nearly twice as many multiple MTBI compared to single MTBIs
Frequency of cannabis use – (once a month –to – everyday)
“particularly violent crime, is likely to result from complex interaction of factors such as genetic pre-disposition, emotional stress, poverty, substance abuse and child abuse”
Tom McMillan – Head Injury & Offending consequences...(2)
children are most likely to be injured & least likely to get support
EVEN if TBI is a marker, it may be an important one to pick up!
Systematic neuro-rehabilitation MAY BE A MEASURE OF CRIME PREVENTION IN IN ITSELF…
“sleeper effects” (“crowding” as part of neurplasticity)– esp. relevant to socio-emotional functions at transition to adolescence – important to monitor
The delivery of services to such groups would therefore require close cooperation between health, social and educational systems.
Particularly focus on parenting of at risk children -
