39
Q

Criterion A for substance use disorder

A

Problematic pattern of substance use, occurring over 12/12 period, leading to clinically significant impairment or distress, with ≥ 2 SX:

  • Impaired control
  • Social impairment
  • Risky use
  • Pharmacological criteria
40
Q

Impaired control

A
  1. Substance is used in larger amounts or over a longer period than was originally intended
  2. Persistent desire to cut down or regulate substance use and multiple unsuccessful efforts to decrease or discontinue use
  3. Spend a great deal of time obtaining the substance, using the substance, or recovering from its effects
  4. An intense desire or urge for the drug (i.e. craving) that may occur at any time but is more likely when in an environment where the drug previously was obtained or used
41
Q

Social impairment

  2. Consistent substance use despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the substance
43
Q

Pharmacological criteria

A
  1. A markedly increased dose of the substance is required to achieve the desired effect or a markedly reduced effect occurs when the usual dose is consumed (tolerance)
  2. A withdrawal syndrome occurs when blood or tissue concentrations of a substance decline in an individual who had maintained prolonged heavy use of the substance
44
Q

Comorbitity

A
  • Strong associations with lifetime mood (i.e. bipolar & depressive) and anxiety d/o’s
  • Causality can be bidirectional
  • However, the majority view is that psychiatric d/o precedes substance use d/o
  • Substance use d/o’s develop out of maladaptive attempts at self-medication

Q

What is a hazardous drinker?

A
  • male: 5 or more standard drinks on a typical drinking day

46
Q

Alcohol use disorder: physiological effects

A
  • ethyl alcohol is absorbed into the bloodstream via the lining of the stomach and intestine and then reaches the CNS
  • it influences the receptors associated with the GABA neurotransmitter, leading to talkativeness, confidence and happiness
  • as more alcohol is absorbed, the drinker’s judgement, speech, memory, mood and motor abilities are affected
  • effects are biphasic
  • stimulant effect is counterbalanced by depressant effect

  • Little systematic evidence that it is more effective than placebo
66
Q

Acupuncture for tobacco use

A
  • Some evidence of efficacy compared to control groups

- Much evidence is anecdotal

67
Q

Cannabis effects

A
  • is a sedative/depressant because of its relaxing effects
  • But it also has mild hallucinogenic and stimulant effects (agitation and paranoia).
  • Its medicinal effects have also led to the formation of powerful lobbies for its legalization.
68
Q

risk factors for developing cannabis dependence

A
  • Early age of onset (i.e. first use)
  • Tobacco smoking
  • Regularity of cannabis use
  • Impulsiveness and mood unpredictability

71
Q 
Cognitive deficits (long-term)
cannabis
A

-Very little evidence for permanent neuropsychological deficits
-Regular, heavy cannabis use is associated with:
–A syndrome of underachievement
–Lower educational achievement / income
-Use during school/college years impairs academic performance and therefore career prospects
-BUT: heavy cannabis use is also associated with deprivation and poor educational opportunities
-Amotivational syndrome:
Apathy, loss of ambition, difficulty concentrating

72
Q

caffeine benefits

A
  • Increased alertness, attention, & cognitive function

- Elevated mood, fewer depressive symptoms, lower risk of suicide

73
Q

high doses of caffeine

A
  • psychotic and manic symptoms, while anxiety symptoms are common
  • Individuals with panic d/o and social phobia are particularly vulnerable to the anxiety-generating effects of caffeine
74
Q

explaining substance use disorders (3 areas)

A
  1. developmental
  2. neurological
  3. behavioural
75
Q

Developmental stage 1: experimentation

A
  1. availability
    - legality
    - cost
  2. familial factors
    - regular use among family members
    - Extreme poverty in the childhood home
    - Marital / legal problems in the household
    - Serious psychiatric illness in the household
    - Childhood neglect and abuse
  3. peer group influences:
    - conforming to group norms
    - in-group favouritism
    - cementing friendship (smoking)
    - Substance use determines membership of social groups
  4. media influences
    - exposure to advertising
76
Q

Developmental stage 2: regular use

A
  1. Mood-altering effects
    - A range of drugs “activate the natural reward pathways in the brain by converging on a common circuitry in the limbic system”
    - Drug use is reinforced by the associated pleasurable feelings
    - Craving can occur in the presence of drug-related cues
  2. Self-medication
    - Regular use can result from attempting to mitigate the distress associated with psychiatric d/o’s
    - But the self-medication account has poor predictive ability
    - -People living with anxiety do not prefer alcohol over amphetamines
    - -People with ADHD do not prefer amphetamines over alcohol
  3. Long-term expectations and beliefs
    - Regular use can result from expectations that substance use will have positive effects
    - Regular use can also result from beliefs that the use of a given substance is harmless
  4. Cultural variables
    - E.g. alcohol consumption differs greatly across countries
77
Q

developmental Stage 3:abuse and dependence

A
  1. genetic predisposition
  2. cognitive deficits
  3. Concurrent psychiatric diagnoses:
    - Comorbid psychiatric problems appear to play an important role “for both transition from first use to regular use, and from regular use to abuse and dependence”
  4. Poverty
    - There is evidence that first use increases in probability if one lives in or near an economically poor neighbourhood
    - Conditions of unemployment, lack of recreation, poor educational opportunities create a perfect storm for the descent into abuse and dependence
78
Q

genetic predisposition

A
  • Heritability is around 0.46 for substance use disorders generally
  • As high as 0.78 for alcohol and nicotine dependence
  • Concordance rates for alcohol abuse of 54% (MZ twins) and 28% (DZ twins)
  • Genes can interact with environmental factors like stress (diathesis-stress model)
  • There may be a more general gene-environment interaction
  • -E.g. living in environment with large numbers of young people
  • Genetic factors can also influence tolerance levels to drugs such as alcohol
  • Many individuals with alcohol use disorder appear to have inherited a strong tolerance for alcohol
  • Certain genes (e.g. ALDH2) appear to influence sensitivity to alcohol
  • -Many Asians have a variant form of ALDH2 that slows alcohol metabolism
  • -This may explain why Asians develop alcohol use disorders at only half the rate of non-Asians
79
Q

Cognitive deficits

A
  • Many abusers often exhibit lower IQ, lower educational achievement, and motivational deficits
  • These factors suggest that abusers may lack the coping skills to pull them out of the downward spiral into abuse and depedence
  • However, these deficits may be caused by regular substance use
80
Q

treatment challenges

A
  • Physical effects of dependence
  • Probability of comorbid disorders
  • High rates of relapse

Treatment is typically multifaceted:

  • Detoxification
  • Psychotherapy / counselling
  • Groupwork
  • Skills training
  • Family psychoeducation
81
Q

treatment: Community based programs

A
  1. Alcoholics Anonymous
    - Support group for individuals wanting to abstain
  2. Drug prevention schemes
    - Used with young people to prevent first drug use
    - Peer-pressure resistance training
    - Combating media advertising
    - Peer leadership
    - Change erroneous beliefs about drugs
  3. Residential treatment
    - Controlled environment for detox and longer term support
82
Q

Treatment: behaviour therapies

A
  1. aversion therapy
  2. contingency management therapy
  3. controlled drinking
83
Q

Aversion therapy

A
  • behaviour therapy
  • Pair the drug with another drug that causes unpleasant effects
  • Covert sensitisation (a variant of aversion therapy)
  • Limited evidence for efficacy of aversion therapy
84
Q

Contingency management therapy

A
  • behaviour therapy
  • Contingency management therapy
  • Identifying triggers (stimulus control)
  • Giving rewards (for not using)
  • Becoming more aware of when and how frequently drugs are used
  • Setting attainable goals (non-abstinence goals)
85
Q

Controlled drinking

A
  • behaviour therapy
  • Emphasis is on controlled use, not abstinence
  • Based on assumption that alcohol is unavoidable
  • Teaching control improves self-esteem, sense of responsibility
86
Q

Cognitive behaviour therapies

A
  1. CBT
    -Address dysfunctional beliefs about relapse
    -‘Abstinence violation’ beliefs lead to full relapse
    -Best employed in cases of comorbidity
  2. MET
    Motivational Enhancement Therapy
    -Manage stressful emotional states and their contributory factors
    -Negative mood management, work-related skills, problem-solving skills, communication skills etc.

Both forms are especially effective when combined with family therapy

87
Q

Family and couple therapy

A
  • Helps family members understand reasons for substance use

- Helps them provide support during and after treatment

88
Q

Biological treatments: Detoxification

A

Supervised cessation of substance use that uses drugs in a controlled manner to combat withdrawal symptoms

89
Q

Biological treatments: Antabuse / Disulfiram

A

Affects metabolism of alcohol resulting in nausea / vomiting

90
Q

Biological treatments: Naltrexone, naxolone, and buprenorfine

A
  • Can treat alcohol, cocaine and opioid dependence

- They inhibit the release of endorphins in the brain

91
Q

Biological treatments: Drug maintenance therapies

A

Treating severe d/o’s by substituting drug of choice with a less harmful one (e.g. methadone instead of heroin)
