harmful
what type of alcohol use would compulsion, tolernace, withdrawal and silence of behaviour be associated with?
dependence
why/ how is alcohol tolerance brought on?
liver breaks down quicker as accustomed to it = have to dirnk more to get same effect
what does SBIRT refer to in regards to the screening that any HCP can initially undertake?
screening, brief intervention and referral to treatment
interventions to alcohol aimed at individuals can help make people aware of the potential risks they are taking at an early stage, patients are most likely to change their behaviour if it is tackled early, true or false?
true
3 stages to dealing with alcohol dependence?
screen
brief advice (intervention brief)
behaviour change counselling (extended intervention)
what is the audit C used for?
front line workers who meet patients with alcohol dependence
what equation can you use to work out the units of alcohol?
(total drink vol in ml x % abv ) / 1000
what tools might you use for initial screening questions for alcohol?
audit c or sasq
what would be your course of action if a patient has a audit c score of 5+ and or a sasq of never or less than monthly?
administer audit
if a patient has a lower risk betwene 0-7, what might you provide the patient with?
information
for patients with an increasing risk (8-15) or a higher risk (16-19) what would you provide the patient with?
brief advice and lifestyle intervention
if a person has possible dependence they will have a score of around 20. What should be your course of action for these patients?
refer for specialist support
what does the FRAMES acronym for interventions stand for?
3 important things to DO
feedback,
responsibility,
advice,
3 important things to BE
menu,
empathy
self efficacy
what is the term given to the inability to resist urges and act without foresight?
impulsivity
what is the term given to the stimulus (drug) that increases the probability of further drug taking?
positive reinforcement
what is the term given to the removal (withdrawal) of a stimulus that increases the probability of further drug taking?
negative reinforcement
what is the term given to repetitive behaviour despite the adverse consequences and reduces stress, anxiety and tension?
compulsivity
addiction is fundamentally about?
compulsive behaviour
compulsive drug seeking is initiated outside of what
consciousness
normal flexibility of human behaviour is eroded to a state of compulsive behaviour.
4 symptoms of behavioural syndrome?
dyscontrol
slaience
neuroadaption
compulsive behaviour
which part of the basal ganglia is associated with the reward pathway and motivation?
nucleus accumbens
what part of the basal ganglia is associated with forming habits and routine?
nucleus accumbens
what part of the basal ganglia is associated with forming habits and routine?
dorsal striatium
what part of the brain is associated with withdrawal, unease and anxiety?
extended amygdala
what part of the brain is associated with executive function: planning, priotising, managing time, making decisions and control over substance taking?
prefrontal cortex
addiction (compulsive behaviour) is mediated by a ?
compulsive unit:
- nucleus accumbens
- ventral pallidum
- thalamus
- prefontal cortex
dopamine d2 receptors are lower or higher in addiction?
lower
(less DA receptors to then –> reward circuits)
why do natural reqrds become devalued in drug abusers?
as drug associated cues usurp the motivational circuits
the addiction cycle: 3 stages?
basal ganglia:
1) binge/intoxication
extended amygdala
2) withdrawal/ negative affect
prefrontal cortex
3) preoccupational/ anticipation
when executive function is disrupted in prefrontal cortex, what system inc and what dec?
inc GO system, release glutamate, strong urge
dec STOP system, compulsive drug seeking
what brain structure puts drug seeking into motion without conscious initiation?
nucleus accumbens
what 2 drugs can manage alcohol withdrawal?
chlordiazepoxide
thiamine
chlordiaepoxide is the benzodiazepine of choice for managing alcohol withdrawal. why is this drug class good for this purpose?
dampen noradrenaline response from alcohol withdrawal
what is the rationale behind using thiamine for managing alcohol wtihdrawal?
b vitamin helps replace those not taken in diet
