ACQUIRED BRAIN INJURY (ABI) any damage to the brain that occurs after birth

…causes? § stroke § accident or trauma § brain infection § neurological diseases (Parkinson's disease, Huntington's disease etc. ) § oxygen loss (asthma, neardrowning etc. ) § alcohol or other drug abuse

alcohol and other drug-related brain injury § …alcohol § marijuana/ cannabis § petrol…

PHYSICAL DISABILITY § nerve damage § poor balance and coordination § fatigue § loss of sense of taste or smell § vision and hearing disturbance § speech impairment

COGNITIVE DISABILITY poor memory and concentration (2 in every 3) = reduced ability - to learn - to plan and - to solve problems

“CHALLENGING BEHAVIOUR” for 2 out of 3, the most disabling § increased irritability § poor impulse control § verbal and physical aggression § paranoia, psychosis

alcohol-related brain injury 1 § (“dose response”? ) § NHMRC guidelines (2009) – “ 2 standard” per day ≠ “risk drinking” § National Drug Strategy Household Survey (2007) @ “long-term high risk” = 3. 8% (men), 2. 7% (women) § National Drug Research Institute (2008) 44% of alcohol “consumed at levels that pose risk in the long-term”

alcohol-related brain injury 2 § National Aboriginal and Torres Strait Islander Health Survey (2004 -05 - consumption week prior to the survey) - 16% adults @ long-term /chronic, “risky / high risk” alcohol consumption (↑ 13% in 2001) § [age-standardised] ATSI were 2 X likely to drink at short-term risky/high risk levels at least once a week than non-ATSI

alcohol-related brain injury 3 § “ 2 million Australians at risk of permanent brain damage” § Men @ 6 standard drinks per day (women @ 3 drinks) X 8 -10 years = “high risk of brain damage”

alcohol-related brain injury 4 § cerebellar atrophy § Wernicke's Encephalopathy § Korsakoff's [Amnesic] Syndrome (Wernicke–Korsakoff Syndrome) § hepatic encephalopathy

cannabis/ marijuana[-related brain injury] 1 National Aboriginal and Torres Strait Islander Health Survey, 2004 -2005: - 43% reported “having tried” marijuana - 23% had “used it” in the last 12 months NT Select Committee on Substance Abuse: - survey mid-1980 s “did not detect” use in Top End - 1999: 55% males, 13% females

cannabis/ marijuana[-related brain injury] 2 § 2001 – 2002: 67% males = 2 X non-ATSI NT population (NT rate = 1. 7 times higher) § “concern over cannabis use is lower than warranted…serious long-term effects of cannabis use will become more evident over time, as effects take hold in populations currently engaged in habitual, heavy use. ”

petrol-[related brain injury] 1 (“…lack of verifiable data…”) § 60 deaths in the NT § 2006 : 600 in Central Desert region “sniffing regularly”, 120 “with permanent brain damage”

petrol-[related brain injury] 2 § (“…it is in the remote regions of the NT, SA and WA that petrol sniffing is found…”)? § (National Aboriginal and Torres Strait Islander Social Survey, 20012002 : 4% in non-remote areas “had sniffed petrol” (4% had “used other inhalants”)?

petrol-[related brain injury] 3 § “…petrol sniffing has declined significantly in central Australia over the last two years. ” § sniffers in the APY lands: 178 people (2005) ↓ 70 people (2006) + “anecdotal reports indicated that petrol sniffing has been very limited or non-existent in the six months to August 2008“ § Opal @ 70 communities § [drug use] migration?

TRAUMATIC BRAIN INJURY (TBI) results from external force applied to the head (ATSI = 3 X) § motor vehicle accidents § assaults § falls

over 500, 000 Australians have an acquired brain injury ? “…excluding those in ? “…except for gaols and those living in correctional remote and sparsely institutions” = 40%-80% settled parts…” ? homeless = 10% - 30% ? “…personal response…. people may not have reported… because of the sensitive nature of the condition… lack of awareness…”

assessment/ screening tools? • AUDIT: “not been validated for • use with Indigenous clients” • Kimberley Indigenous Cognitive Assessment • (KICA) “Cog State” Menzies School of Health Research)

recovery? • alcohol? • 25% - complete recovery • 25% - significant recovery • 25% - slight recovery • 25% - no recovery petrol? (Groote Eyland) “ 2 years abstinence…improvement in neurobehavioural performance…often normalised completely”
