Chapter 11 Substance-Related, Addictive, and Impulse-Control Disorders Flashcards
Substance-related and addictive disorders
- A class of disorders that affects the way people think, feel, and behave.
- Range of problems associated with the use and abuse of drugs such as alcohol, cocaine, heroin, and other substances people use to alter the way they think, feel, and behave. These are extremely costly in human and financial terms.
Impulse-control disorders
- Disorder that deprives a person of the ability to resist acting on a drive or temptation
- Disorders in which a person acts on an irresistible, but potentially harmful, impulse.
Polysubstance use
Use of multiple mind- and behavior- altering substances, such as drugs.
Substance use
The ingestion of psychoactive substances in moderate amounts that does not significantly interfere with social, educational, or occupational functioning.
Substance intoxication
A physiological reaction, such as impaired judgement and motor ability, as well as mood change, resulting from the ingestion of a psychoactive substance.
Substance abuse
A pattern of psychoactive substance use leading to significant distress or impairment in social and occupational roles and in hazardous situations.
Dependence
A maladaptive pattern of substance use characterized by the need for increased amount to achieve the desired effect, negative physical effects when the substance is withdrawn, unsuccessful efforts to control its use, and substantial effort expended to seek it or recover from its effects. Also known as addiction.
Substance
Chemical compounds that are ingested to alter mood or behavior.
Psychoactive substances
Substances, such as drugs, that alter mood or behavior
Tolerance
Need for increased amounts of a substance to achieve the desired effect, and a diminished effect with continued use of the same amount.
Withdrawal
Severely negative physiological reaction to removal of a psychoactive substance, which can be alleviated by the same or a similar substance.
Antisocial personality disorder
Cluster B (dramatic, emotional, or erratic) personality disorder involving a pervasive pattern of disregard for and violation of the rights of others.
Depressants
- These substances result in behavioral sedation and can induce relaxation. They include alcohol (ethylalcohol) and the sedative and hypnotic drugs in the families of barbiturates (for example, Seconal) and benzodiazepines (for example, Valium, Xanax)
Stimulants
These substances cause us to be more active and alert and can elevate mood. Included in this group are amphetamines, cocaine, nicotine, and caffeine.
Opiates
The major effect of these substances is to produce analgesia temporarily (reduce pain) and euphoria. Heroin, opium, codeine, and morphine are included in this group.
Hallucinogens
These substances alter sensory perception and can produce delusions, paranoia, and hallucinations. Cannabis and LSD are included in this category.
Other Drugs of Abuse
Other substances that are abused but do not fit neatly into one of the categories here include inhalants (for example, airplane glue), anabolic steroids, and other over-the-counter and prescription medications (for example, nitrous oxide). These substances produce a variety of psychoactive effects that are characteristic of the substances described in the previous categories.
Gambling Disorder
As with the ingestion of the substances just described, individuals who display gambling disorder are unable to resist the urge to gamble which, in turn, results in negative personal consequences (e.g., divorce, loss of employment).
Alcohol-related disorders
Cognitive, biological, behavioral, and social problems associated with alcohol use and abuse.
Fermentation
Decomposition process by which yeasts, water, and sugar form alcohol.
Breathalyzer test
Measure of alcohol intoxication that uses a breath sample because some consumed alcohol is vaporized in the lungs and exhaled.
Gamma-aminobutyric acid (GABA)
Neurotransmitter that reduces activity across the synapse and thus inhibits a range of behaviors and emotions, especially generalized anxiety.
Glutamate system
Excitatory neurotransmitter system that may be the avenue by which alcohol affects cognitive abilities.
Withdrawal delirium (delirium tremens/DTs)
Frightening hallucinations and body tremors that result when a heavy drinker withdraws from alcohol.
