Q

Opioid use disorder: an example • Heroin

A
  • After just a few weeks, users may become caught in a pattern of abuse (and often dependence)

  • Early withdrawal symptoms include anxiety and restlessness; later symptoms include twitching, aches, fever, vomiting, diarrhea, and weight loss from dehydration
  • Increased doses are required to avoid withdrawal

People often take more than one drug at a time, known as

A

polysubstance use
• Cross-tolerance
• Synergistic effects-increase in effects that occur when more Ethan one substance is taken
• Similar actions-two or more drugs have similar action- both depress-lower and lower

• Each year tens of thousands of people are hospitalized because of polysubstance use
• May be accidental or intentional

27
Q

What Causes Substance Use Disorders?• Sociocultural views

A
  • People who are most likely to develop these disorders:
  • Living in stressful socioeconomic conditions
  • Have families that value or tolerate drug use
  • Are confronted regularly by other kinds of stress
28
Q

• Psychodynamic views

A
  • People who are most likely to develop these disorders:
  • Have powerful childhood dependency needs
  • Display a substance abuse personality
29
Q

• Cognitive-behavioral views

A
  • People who are most likely to develop these disorders:
  • Operant conditioned by tension-reduction, rewarding effects of drugs (self-medication)
  • Have rewards-produced expectancy that substances will be rewarding
  • Influenced by classical conditioning when cues or objects are present during drug use
30
Q

• Biological views

A 
• Biological factors play a
major role in drug misuse
 • Genetic predisposition
 • Neurotransmitters
• Braincircuits
31
Q

• Genetic predisposition

A
  • Similarity of alcohol preferences among alcohol-preferring animals and their offspring
  • Alcoholism concordance rate in identical twins
  • Biological parent–adoptee child alcohol abuse rate
  • Abnormal form of dopamine-2 (D-2) receptor gene in people with substance use disorders
32
Q

• Neurotransmitters

drug tolerance and withdrawal symptoms are caused by

A
  • Drug tolerance and withdrawal symptoms are caused by cutbacks in the brain’s production of particular neurotransmitters during excessive and chronic drug use
  • Lower GABA production: Alcohol or benzodiazepines
  • Lower endorphin production: Cocaine or amphetamines
  • Reduced anandamide production: Marijuana
33
Q

• Brain circuits

what is the key Neurotramsitter

A
  • Reward circuit (reward center)
  • Pleasure pathway
  • Dopamine is the key NT
  • Drugs stimulate structures directly and indirectly(through dopamine activity)
34
Q

• Incentive-sensitization theory
-reward deficiency syndrome
defects in what receptor

A
  • When substances repeatedly stimulate the reward center, the center develops a hypersensitivity to the substances- contributes to future desire
  • Reward-deficiency syndrome
  • The reward center is not readily activated by “normal” life events so the person turns to drugs to stimulate this pleasure pathway, particularly in times of stress
  • Defects in D-2 receptors have been cited as a possible cause
35
Q

• Developmental psychopathology view

externalizing or internalizing temperament

A
  • Substance use disorders
  • Genetically inherited predisposition
  • Externalizing(impulsivity, aggression-family,school conflicts, social problems-onset for drug use) or internalizing temperament(depression, sadness low self concept-turn to drugs)
  • Numerous stressors throughout childhood
  • Inadequate parenting
  • Rewarding substance use experiences
  • Relationships with. peers who use drugs
36
Q

How Are Substance Use Disorders Treated?

A

• The value of treatment for substance abuse or dependence can be difficult to determine
• Different substance use disorders pose different problems
• Many people with substance abuse patterns drop out of treatment early
• Some people recover without any intervention at all
• Different criteria are used by different clinical researchers
-difficult to determine, drop out of treatment, recover without

37
Q

Psychodynamic therapies

A

• Clients are helped to become aware of and correct underlying
needs and conflicts related to drug use

38
Q

• Cognitive-behavioral techniques

A

• Therapists use aversion therapy-unpleasant stimuli when performing undesirable behaviors of taking drugs
-contingency management-incentives to drug free urine specimen

relapse-prevention training-treat alcohol use disorder in which clients are taught to plan ahead and apply coping strategies in situations that trigger drinking

, and acceptance and commitment therapy-accept thoughts rather than eliminate them

39
Q

• Biological treatments
antagonist
detoxification

A

• Drug maintenance therapy
• Methadone maintenance programs are designed to provide a safe, legally and medically supervised substitute for heroin
detoxification-medically supervised withdrawal from a drug
antagonist- drugs that block or change effects of an addictive drug

40
Q

• Sociocultural therapies

A
  • Sociocultural theorists (family-social and multicultural theorists) believe psychological problems emerge in a social setting and are best treated in a social context
  • Self-help-alcohol anonymous and residential treatment programs - place where people who were formally addicted to drugs live, work and socialize in a drug free environment
  • Culture-and gender-sensitive programs
  • Community prevention programs
41
Q 
• Gambling disorder
defined by the 
-biological factors
\_\_\_\_\_dopamine activity
treatment same as others
A
  • Defined by the addictive nature of the behavior
  • Genetic predisposition
  • Heightened dopamine activity and dysfunction when gambling
  • Impulsive, novelty-seeking personality style
  • Repeated and cognitive mistakes
  • Treatment
  • Cognitive-behavioral approaches (relapse-prevention training)
  • Biological approaches (opioid antagonists)
  • Self-help programs (Gamblers Anonymous)
  • Prevalence
  • 3 to10 percent of teenagers and college students
  • Internet gaming disorder
  • Under study for possible inclusion in future DSM edition
42
Q

• Internet gaming disorder: awaiting official status

A
  • People increasingly turn to the Internet for activities that used to take place in the “real world”, giving rise to an uncontrollable need to be online
  • Internet use disorder, internet addiction
  • Specific symptoms of this pattern parallel those found in substance use disorders or gambling disorders, extending from the loss of outside interests to possible withdrawal reactions when Internet use is not possible (APA, 2013).
