“…peak of peaks”
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, near-drowning etc.) alcohol or other drug abuse
…alcohol marijuana/ cannabis petrol…
alcohol and other drug-related brain injury
nerve damage poor balance and coordination fatigue loss of sense of taste or smell vision and hearing disturbance speech impairment
PHYSICAL DISABILITY
COGNITIVE DISABILITY
= reduced ability
- to learn- to plan and - to solve problems
poor memory and concentration (2 in every 3)
“CHALLENGING BEHAVIOUR”
for 2 out of 3, the most disabling increased irritability
poor impulse control verbal and physical aggression paranoia, psychosis
(“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 1
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 2X likely to drink at short-term risky/high risk levels at least once a week than non-ATSI
alcohol-related brain injury 2
“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 3
cerebellar atrophy
Wernicke's Encephalopathy
Korsakoff's [Amnesic] Syndrome (Wernicke–Korsakoff Syndrome)
hepatic encephalopathy
alcohol-related brain injury 4
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-1980s “did not detect” use in Top End- 1999: 55% males, 13% females
cannabis/ marijuana[-related brain injury] 1
2001 – 2002: 67% males = 2X 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.”
cannabis/ marijuana[-related brain injury] 2
60 deaths in the NT
2006 : 600 in Central Desert region “sniffing regularly”, 120 “with permanent brain damage”
petrol-[related brain injury] 1
(“…lack of verifiable data…”)
(“…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, 2001-2002 : 4% in non-remote areas “had sniffed petrol” (4% had “used other inhalants”)?
petrol-[related brain injury] 2
“…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?
petrol-[related brain injury] 3
results from external force applied to the
head
(ATSI = 3X) motor vehicle accidents assaults falls
TRAUMATIC BRAIN INJURY (TBI)
? “…excluding those in gaols
and correctional institutions”= 40%-80%
? homeless= 10% - 30%
? “…personal response…. people may
not have reported…because of the
sensitive nature of the condition… lack of
awareness…”
over 500,000 Australians have an acquired brain
injury? “…except for those living in
remote and sparsely settled
parts…”
“Cog State”Menzies School of Health Research)
assessment/ screening tools?
Kimberley Indigenous Cognitive Assessment
(KICA)
AUDIT: “not been validated foruse with Indigenous clients”
petrol?(Groote Eyland)
“2 years abstinence…improvement in neurobehavioural performance…
often normalised completely”
recovery?alcohol?
25% - complete recovery25% - significant recovery
25% - slight recovery25% - no recovery
