Need for new policies to influence practice re: TBI in prison populations
mental health & drug/alcohol problems identified
“ relative to general population, [prisoners]…experience poorer physical, mental, and social health…[more] mental illness and disability , drug, alcohol…suicide, self harm…lower life expectance [etc.]…” Orme et al. BMJ editorial, 2005, 330. p 918
and see Fazel & Danesh ( 2002a (Lancet))
“… . delivery of services to prisoners with anxiety and affective disorders, drugs and alcohol problems, brain injury , learning disability, challenging behaviour and repetitive self-harm has changed little or worsened .” Dearbhla Duffy, et al. (2003) p. 242 (our emphasis)
TBI is largely neglected from policy documents (Youth Crime Action Plan, 2008 and Bradley report 2009)
circuitry sub-serving control of impulses, judgment, and decision-making.
implications of late maturation of this area have entered educational, social, political, and judicial discourse
Brain development in children and adolescents: Insights from anatomical magnetic resonance imaging Rhoshel K. Lenroota and Jay N. Giedd (2006) Savage, 2009
Yates, Williams et al. 2006, JNNP: 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
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
Wrightson, McGinn and Gronwall (1995)
pre-school children - MTBI tested after injury and then at 6 months and a year (V. orthopdeic control group).
no differences after injury on a range of cognitive tasks.
But, at 6 months and then at 1 year, the MTBI children less good on visual problem solving and association with further injury.
Limond et al. 2009
follow up of moderate-severe and (mostly) complicated MTBI showed persisting disabilities at 1 year –
> lack of pro-social behaviour and emotional symptoms
Prevalence studies of TBI in adult offender groups
Self-report prevalence studies of TBI - with 25% to 87% of inmates reportedly experiencing a head injury (Schofield et al., 2006; Slaughter, Fann and Ehde, 2003; Morrell et al., 1998).
Slaughter et al (2003) - TBI in inmates in a county jail in the USA.
87% lifetime prevalence and 36% in the previous year.
TBI in the previous year had worse anger and higher psychiatric disturbance.
Barnfield and Leathem (1998) New Zealand, had 118 respondents
86.4% reported some form of “head injury” with 56.7% reporting more than one blow to the head.
concomitant reports of difficulties with memory and socialization.
Analysis of medical records.
De Souza (2003) Brazil -
Of 3233 offenders there were 133 cases of TBI reported (39 “mild” and 94 “moderate or severe”).
In the majority (111 cases) there was no account taken of the injury by service providers.
Prevalence studies of TBI in young offender groups
Huxx, Bong, Skinner, Belau, & Sanger (1998)
TBI in offending and non-offending youths (50% versus 40%)
greater biomechanical forces - such as fights and road accidents versus sports injury
higher levels of immediate symptoms, such as headaches, dizziness and losses of consciousness.
Perron and Howard (2008)
period prevalence and correlates of TBI – with a LOC of 20 minutes or more - in 720 youth offenders.
18.3% reported such a head injury.
Male gender, co-morbid psychiatric diagnosis, earlier onset of criminal behaviour and substance use were associated with TBI.
TBI a risk factor for crime??...
Timonen et al (2002)
population based cohort study in Finland involving more than 12,000 subjects
TBI during childhood or adolescence associated with
fourfold increased risk of developing later mental disorder with coexisting offending in adult (aged 31) male cohort members (OR 4.1)
TBI might have been a result of high novelty seeking and low harm avoidance in people susceptible (for issues of genetics, family background, social forces etc.) to risky behaviours – coincidental to crime….BUT
TBI earlier than age 12 were found to have committed crimes significantly earlier than those who had a head injury later
Therefore - temporal congruency suggests a causal link
Fazel, Philipson, Gardiner, et al. 2009
meta-analysis of studies relating to violence and neurological conditions indicated that TBI was a moderate risk factor for violence whereas epilepsy was inversely correlated with risk
McKinlay A., et al. “ Are children who experience Traumatic Brain Injury more likely to engage in criminal behaviour during their adult lives?” 33 rd ASSBI(Abstract) Brain Impairment . 2010
longitudinal epidemiological study of a birth cohort of 1265 children born in Christchurch (New Zealand) urban region in mid-1977.
Groups: MTBI “hospitalised” “Not hospitalised” and “No-Injury”
adjustment for gender, SES...(BUT ?? Family issues)
Adjusted rates - compared to non-injured individuals, both TBI groups were more likely to be arrested (relative risk (RR)=2.03 and RR=1.68), involved in property offences (RR=2.08 and RR=1.54) and violent offences (RR=1.35 and RR=2.29) (all p<0.01).
“ clear evidence of ongoing problems for individuals who had experienced a TBI compared to their non injured counterparts”.
Associations between TBI & Crime
Blake, Pincus and Buckner (1995)
assessed thirty-one individuals awaiting trial or sentencing for murder, and found evidence of ``frontal'' dysfunction in 20 (64.5%).
Vietnam Head Injury Study (VHIS) (Grafman et al 1996)
rate of 14% for fighting and property damage in head injured veterans compared to 4% in non-head injured controls.
TBI & Crime: Coincidence or causal?
Turkstra et al. (2003)
offenders with TBI against “true peers” without TBI
20 individuals convicted of violent crime compared to 20 non convicted controls (matched for education, age and employment ).
TBI NOT more common in the offender group BUT there was variance on severity of injury
non-offending group– typically – Milder TBI from (eg sports).
offending group injuries
More assaults (with probable longer lasting changes in behaviour).
had more issue related to anger control.
TBI is not necessary for crime, but that TBI may contribute to “expression of violence” - increase the risk “threshold” in vulnerable people.
Rates of Mild – Severe TBI in Prisoners Williams et al (2010) Brain Injury 453 males held in HMP Exeter Pps: 196 aged between 18 and 54 years (43% response rate) sentenced or remanded
Percentage of population reporting TBI & type & TIME of injury (Williams et al (2010)) “ Any tbi?” No 39.6 % Yes 60.4%
we estimate that
65% may have had a TBI.
5.6 % Moderate
Average age at 1st imprisonment: 21 Years – Non-TBI 16 years - TBI
Re-offending The number of participants that were re-offenders differed significantly according to whether they had reported “head injuries” [ Chi squ (1, N= 195)=11.98, p = .001]. No Yes Any TBI? Bars show counts No Yes Is this the first time in prison? 0 50 100 150 Count
Young Offenders & brain injury
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%
“ joyriding”: 14.7%
drug offences: 11.6%
Williams, Cordan et al (in press, Neuropsychological Rehabilitation):
Young offender population and TBI
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
Participants w/ TBIs
had an average of 2 more convictions (M = 7.23) compared to non-TBI (sig. after age effects etc.)
Those with x3+ TBI with greater violence
Young Offenders, TBI and Drugs Frequency of cannabis use – (once a month –to – everyday)
TBI in Prisoners: Childhood injury and rehabilitation
Leon-Carrion J, Ramos FJ. ( 2003) (BI)
Retrospective factor analytic study of links between head injuries (in childhood and adolescence) in adult violent and non-violent prisoners.
subjects in both groups had a history of academic difficulties.
Trend for both groups to have had behavioural and academic problems at school
Head injury in addition to prior learning disability/school problems increases chances of having a violent offending profile
Violent offending (noted) to be “associated with non-treated brain injury”
? rehabilitation of head injury may be a measure of crime prevention
TBI and Crime – causal or co-incidental?
The evidence is not clear cut
there are many confounding factors within the relationships between injury and later offending
the link between crime and TBI may be an epiphenomenon – whereby TBI is “marker” for of various contextual factors associated with crime - indeed
“ 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 ”
Turkstra, 2004 (P 40).
better screening for head injury at pre-sentencing and on admission to prison/custodial services –
for better understanding of risk, and for rehabilitative purposes
Esp. those with executive & socio-affective difficulties who may have difficulty in changing behaviour patterns in response to contingencies
“ The person at risk of violence needs to recognise his risk and take preventative steps…but [those with]…damage to…prefrontal cortex…may not be able to reflect on their behaviour and take responsibility…[as their] internal soul-searching [is] damaged …” Raine (2002)
rehabilitation interventions in custodial systems – Targeted at impulse control/socio-emotional processing (esp. ToM/Empathy etc.)
Screening & enhancing rehabilitation
Service development and community involvement
Services – as NHS provision is moving “into” prison groups:
Would also be helpful to have TBI reported as a chronic condition for which offenders within and outside custodial systems would have support for managing consequences of injury
e.g. in line with Bradley report - via Primary care – Poly-clinics – linked to specialist support in Neuro-rehabilitation centres
Policing of “at risk” groups in community (Youth Crime Action Plan, 2008)
Eg role of Police Community Support Officers & inter-agency working
Esp. with early & intensive family interventions
Alternatives to custody – eg. restorative justice re: improving empathy
What can be done: Younger groups
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 -

Deputy Prime Minister Nick Clegg recently noted that the nation was "criminalising far too many young children". http://news.bbc.co.uk/1/hi/uk/8565619.stm
Public safety and long term economic advantage could be gained by better, earlier, targeted interventions to:
reduce impact of injury
May be complicated to deliver – BUT:

The brain NEEDS to be socialised...
Children’s brain need to be IN Society to be SOCIALISED… (as Vygotsky may have said)
“ We have to understand the brain as part of a socio-cultural environment. Our brain is shaped by … interaction with other brains. The brain is essentially a social organ that we can not understand isolated from its environment .”
