4 general groupings of indicators
social impairment, impairment of control over use, risky use and pharmacological criteria
impairment of control
taking substance in greater amounts or for longer than intended, desire to cut down or quit, lots of time spent trying to obtain or recover from the substance, craving
social impairment
failure to fulfill major role obligations at work, home or school - continued despite clear negative consequences on relationships
risky use
use when it is physically dangerous, continued use despite having a problem that is made worse by the substance
pharmacological dependence
tolerance and withdrawal
tolerance
increased amounts of substance to achieve same effect
withdrawal
experience unpleasant and sometimes dangerous symptoms when substance is removed from body
which two methods of ingesting substance are the quickest to reach the brain
inhaling and injection (IV)
substance-induced disorders
associated with each of the 10 drug classes, including intoxication, withdrawal, and other substances
polysubstance abuse
simultaneous misuse or dependence upon two or more substances
low-risk drinking guidelines
indication of upper limits on drinking so that drinking is not likely to lead to physical impairment
ethyl alcohol
effective chemical compound in alcoholic beverages - reduces anxiety, produces euphoria, and creates a sense of well-being
Blood alcohol level
0.08% - usual
alcohol dehydrogenase
breaks down alcohol - women have less of this
what does alcohol do to your cycle of sleep
supresses REM phase of sleep, so first part of night is good then will rebound
Korsakoff’s psychosis
chronic disease characterized by impaired memory and a loss of contact with reality
fetal alcohol syndrome
patter of facial dysmorphology, growth retardation and CNS dysfunction caused by mother’s drinking habits
twins studies for alcohol
male monozygotic twins are more similar in their tendencies to develop problems with alcohol abuse and dependence
behavioral disinhibition
people with alcohol problems tend to have a relative inability to inhibit behavioural impulses
negative emotionality
tendency to experience psychological distress, anxiety, and depression
tension-reduction
hypothesis that drinking is reinforced by its ability to reduce tension, anxiety, anger, depression and other unpleasant emotions
alcohol expectancy theory
drinking behaviour is largely determined by the reinforcement that an individual expects to receive from it
behavioural tolerance
need for a greater amount for the same effect - greatest when conditioned environmental cues are present
acetaldehyde
breaks down alcohol - then it is further broken down by the enzyme aldehyde hydrogenase
short-term consequences of alcohol
cognitive, driving, health
long-term consequences of alcohol
related to genetic vulnerability, frequency/duration of alcohol use, severity of and frequency of binge drinking
Minnesota Model
popular treatment for people who show signs of withdrawal, treatment begins in a hospital or detoxification clinic under medical supervision - abstinence is the goal
Pharmacotherapy
assist in detoxification to reduce the pleasurable effects associated with drinking and to produce nausea when alcohol is consumed
antagonist drug
targets the neurotransmitters that mediate alcohol’s effects on the rain and “blocks” the pleasurable effects of alcohol
agonist drug
facilitates the inhibitory action of the neurotransmitter GABA at its receptors
antabuse
block the action of the metabolizing enzyme acetaldehyde dehydrogenase, resulting in a buildup of it in the body
advantage of antabuse
helping family member regain trust in the individual’s resolve to not drink
success of agonist drug
depends on the compliance of the individual
success of antagonist drug
reduces sensation of craving
alcoholics anonymous
goal is complete abstinence - believe there is no cure for alcoholism - believe in “higher power” to help them
success of alcoholics anonymous
effective treatment for some - others find a hard time with the spirituality aspect
behavioral treatment
based on operant conditioning principles - treats problem drinking as a learned behavior
