Synonyms and keywords: Stimulant intoxication; stimulant withdrawal
Stimulant use disorder is a substance use disease characterized by stimulant drug misuse leading to tolerance, dependence, and abuse. Acute stimulant intoxication is associated with euphoria with affective blunting, hypervigilance, anxiety, and impaired judgment with somatic symptoms characteristic of stimulant drugs such as tachycardia, hypertension, perspiration, and psychomotor agitation. Abrupt discontinuation of stimulants is associated with a withdrawal syndrome characterized by a dysphoric mood with fatigue, vivid, unpleasant dreams, increased appetite, and sleep disturbances.[1]
Epidemiology and Demographics[edit | edit source]
The prevalence of stimulant use disorder is 2,000 per 100,000 (0.2%) of the overall population.[1]
Poor prognostic factors include:
- Antisocial personality
- Impulsivity
- Substance use disorders
- Living in an unstable home environment[1]
DSM-V Diagnostic Criteria for Stimulant Use Disorder[1][edit | edit source]
| “
|
A. A pattern of amphetamine-type substance, cocaine, or other stimulant use leading to clinically significant impairment or distress, as manifested by at least two of the following, occurring within a 12-month period:
- The stimulant is often taken in larger amounts or over a longer period than was intended.
- There is a persistent desire or unsuccessful efforts to cut down or control stimulant use.
- A great deal of time is spent in activities necessary to obtain the stimulant, use the stimulant, or recover from its effects.
- Craving, or a strong desire or urge to use the stimulant.
- Recurrent stimulant use resulting in a failure to fulfill major role obligations at work, school, or home.
- Continued stimulant use despite having persistent or recurrent social or intepersonal problems caused or exacerbated by the effects of the stimulant.
- Important social, occupational, or recreational activities are given up or reduced because of stimulant use.
- Recurrent stimulant use in situations in which it is physically hazardous.
- Stimulant use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the stimulant.
- Tolerance, as defined by either of the following:
- a. A need for markedly increased amounts of the stimulant to achieve intoxication or desired effect.
- b. A markedly diminished effect with continued use of the same amount of the stimulant.Note: This criterion is not considered to be met for those taking stimulant medications solely under appropriate medical supervision, such as medications for attention-deficit/hyperactivity disorder or narcolepsy.
- 11. Withdrawal, as manifested by either of the following:
- a. The characteristic withdrawal syndrome for the stimulant (refer to Criteria A and B of the criteria set for stimulant withdrawal).
- b. The stimulant (or a closely related substance) is taken to relieve or avoid withdrawal symptoms.
This criterion is not considered to be met for those taking stimulant medications solely under appropriate medical supervision, such as medications for attention-deficit hyperactivity disorder or narcolepsy.
Specify if:
- In early remission: After full criteria for stimulant use disorder were previously met, none of the criteria for stimulant use disorder have been met for at least 3 months but for less than 12 months (with the exception that Criterion A4, “Craving, or a strong desire or urge to use the stimulant,” may be met).
- In sustained remission: After full criteria for stimulant use disorder were previously met, none of the criteria for stimulant use disorder have been met at any time during a period of 12 months or longer (with the exception that Criterion A4, “Craving, or a strong desire or urge to use the stimulant,” may be met).
Specify if:
- In a controlled environment: This additional specifier is used if the individual is in an environment where access to stimulants is restricted.
Specify current severity:
- Mild: Presence of 2-3 symptoms.
- Amphetamine-type substance
- Cocaine
- Other or unspecified stimulant
- Moderate: Presence of 4-5 symptoms.
- Amphetamine-type substance
- Cocaine
- Other or unspecified stimulant
- Severe: Presence of 6 or more symptoms.
- Amphetamine-type substance
- Cocaine
- Other or unspecified stimulant
