The two diagnoses for Substance-Related Disorders in the DSM-5 are:
Substance-induced disorders and Substance-use disorders
Substance-induced disorders
– Disorders, such as intoxication, that can be induced by using psychoactive substances.
Substance-use disorders
– patterns of maladaptive use of psychoactive substances that lead to significant levels of impaired functioning or personal distress.
Substance intoxication
– A pattern of repeated episodes of intoxication, which is a state of drunkenness or of being “high.”
Reversible and temporary condition
Substance abuse
– Recurrent substance use that results in significant adverse consequences in functioning
Substance dependence
– lack of control over substance use
Two forms of dependence:
Physiological and psychological
Addiction
– Impaired control over the use of a chemical substance, accompanied by physiological dependence.
Physiological dependence
– A condition in which the drug user’s body comes to depend on a steady supply of the substance.
Defined largely in terms of tolerance and withdrawal
Psychological dependence
– Compulsive use of a substance to meet a psychological need.
Also known as habituation
Impairment of control
– exceeding amounts of a substance or time using than intended
Tolerance
– Physical habituation to a drug such that with frequent use:
1) higher doses are needed to achieve the same effects,
or
2) the same amount of substance has a diminished effect.
Withdrawl syndrome
– A characteristic cluster of symptoms following the sudden reduction or cessation of use of a psychoactive substance after physiological dependence has developed.
Substance-use disorders
– Patterns of maladaptive use of psychoactive substances that are identified by the particular drug associated with problematic use (e.g., “alcohol use disorder”).
Characterized by a range of features that include the following:
persistent problems cutting back or controlling use of the substance
developing tolerance or a withdrawal syndrome
spending an excessive amount of time seeking/using the substance
using the substance in situations that pose a risk to the person’s safety or the safety of others (such as repeatedly drinking and driving).
The DSM-5 has included a category for nonchemical forms of addiction, including what 3 disorders?
Gambling disorder
kleptomania (compulsive stealing)
pyromania (compulsive fire-setting).
These disorders were previously classified in the DSM-IV in a diagnostic category called Impulse Control Disorders.
Characterized by difficulties controlling or restraining impulsive behavior.
polysubstance abuse
May be addicted to more than one thing or the substance they are addicted to might be laced with other things that their body is reacting to
depressants
drugs that slows down or curbs the activity of the central nervous system.
It reduces feelings of tension and anxiety, slows movement, and impairs cognitive processes.
In high doses, depressants can arrest vital functions and cause death.
the most widely used substance in the United States and worldwide
Alcohol
Alcoholism
– An alcohol dependence disorder or addiction that results in serious personal, social, occupational, or health problems.
the disease model
- the most widely held view of alcoholism
- the belief that alcoholism is a medical illness or disease.
risk factors for developing alcoholism and alcohol-related problems
- Gender
- Age
- Antisocial personality disorder
- Family history
- Sociodemographic factors
Canadian Consumption Statistics
77% of Canadians reported drinking in the past 12 months
12% former drinkers
11% never drink
90% of youth aged 18-24 drink during the course of a year
Heaviest drinking reported by those with the least education and those out of work
Effects of alcohol
- Alcohol reduces anxiety, produces euphoria, and creates a sense of well-being
- Reduces inhibitions
- Short-term effects are strongly related to expectations of the alcohol
- Alcohol level, aka blood alcohol level (BAL), expressed as a percentage of blood
Physiological Effects of Alcohol
Alcohol appears to work by heightening activity of the neurotransmitter GABA.
GABA is an inhibitory neurotransmitter.
Increasing GABA activity produces feelings of relaxation.
