F1x.0 Intoxication

G1. There must be clear evidence of recent use of a psychoactive substance (or substances) at sufficiently high dose levels to be consistent with intoxication. G2. There must be symptoms or signs of intoxication compatible with the known actions of the particular substance (or substances), as specified below, and of sufficient severity to produce disturbances in the level of consciousness, cognition, perception, affect, or behaviour that are of clinical importance. G3. The symptoms or signs present cannot be accounted for by a medical disorder unrelated to substance use, and not better accounted for by another mental or behavioural disorder. Acute intoxication frequently occurs in persons who have more persistent alcohol- or drug-related problems in addition. Where there are such problems, e.g. harmful use (F1x.1), dependence syndrome (F1x.2), or psychotic disorder (F1x.5), they should also be recorded. The following five-character codes may be used to indicate whether the acute intoxication was associated with any complications: Symptoms of varying severity, usually dose-dependent. F1x.01 With trauma or other bodily injury F1x.02 With other medical complications Examples are haematemesis, inhalation of vomit. F1x.04 With perceptual distortions
F10.0 Acute intoxication due to use of alcohol
A. The general criteria for acute intoxication (F1x.0) must be met. B. There must be dysfunctional behaviour, as evidenced by at least one of the (1) disinhibition; (2) argumentativeness; (3) aggression; (4) lability of mood; (5) impaired attention; (6) impaired judgment; (7) interference with personal functioning. C. At least one of the following signs must be present: (1) unsteady gait; (2) difficulty in standing; (3) slurred speech; (4) nystagmus; (5) decreased level of consciousness (e.g. stupor, coma); (6) flushed face; (7) conjunctival injection. Comment
When severe, acute alcohol intoxication may be accompanied by hypotension,
hypothermia, and depression of the gag reflex.
If desired, the blood alcohol level may be specified by using ICD-10 codes Y90.0-Y90.8. Code Y91.- may be used to specify the clinical severity of intoxication if the blood alcohol level is not available. F10.07 Pathological alcohol intoxication Note. The status of this condition is being examined. These research criteria must be regarded as tentative. A. The general criteria for acute intoxication (F1x.0) must be met, with the exception that pathological intoxication occurs after drinking amounts of alcohol insufficient to cause intoxication in most people. B. There is verbally aggressive or physically violent behaviour that is not typical of C. The intoxication occurs very soon (usually a few minutes) after consumption of D. There is no evidence of organic cerebral disorder or other mental disorders. Comment
This is an uncommon condition. The blood alcohol levels found in this disorder are
lower than those that would cause acute intoxication in most people, i.e. below 40
mg/100 ml.

F1x.1 Harmful use

A. There must be clear evidence that the substance use was responsible for (or substantially contributed to) physical or psychological harm, including impaired judgement or dysfunctional behaviour, which may lead to disability or have adverse consequences for interpersonal relationships. B. The nature of the harm should be clearly identifiable (and specified). C. The pattern of use has persisted for at least 1 month or has occurred repeatedly D. The disorder does not meet the criteria for any other mental or behavioural disorder related to the same drug in the same time period (except for acute intoxication, F1x.0).
F1x.2 Dependence syndrome

Three or more of the following manifestations should have occurred together for at least 1 month or, if persisting for periods of less than 1 month, should have occurred together repeatedly within a 12-month period: (1) a strong desire or sense of compulsion to take the substance; (2) impaired capacity to control substance-taking behaviour in terms of its onset, termination, or levels of use, as evidenced by: the substance being often taken in larger amounts or over a longer period than intended; or by a persistent desire or unsuccessful efforts to reduce or control substance use; (3) a physiological withdrawal state (see F1x.3 and F1x.4) when substance use is reduced or ceased, as evidenced by the characteristic withdrawal syndrome for the substance, or by use of the same (or closely related) substance with the intention of relieving or avoiding withdrawal symptoms; (4) evidence of tolerance to the effects of the substance, such that there is a need for significantly increased amounts of the substance to achieve intoxication or the desired effect, or a markedly diminished effect with continued use of the same amount of the substance; (5) preoccupation with substance use, as manifested by important alternative pleasures or interests being given up or reduced because of substance use; or a great deal of time being spent in activities necessary to obtain, take, or recover from the effects of the substance; (6) persistent substance use despite clear evidence of harmful consequences (see F1x.1), as evidenced by continued use when the individual is actually aware, or may be expected to be aware, of the nature and extent of harm. Diagnosis of the dependence syndrome may be further specified by the following five- and six-character codes: F1x.20 Currently abstinent F1x.21 Currently abstinent but in a protected environment (e.g. in hospital, in a therapeutic community, in prison, etc.) F1x.22 Currently on a clinically supervised maintenance or replacement (e.g. with methadone; nicotine gum or nicotine patch) F1x.23 Currently abstinent, but receiving treatment with aversive or blocking F1x.24 Currently using the substance [active dependence] F1x.240 Without physical features The course of the dependence may be further specified, if desired, as follows: F1x.25 Continuous use F1x.26 Episodic use [dipsomania] F1x.3 Withdrawal state

G1. There must be clear evidence of recent cessation or reduction of substance use after repeated, and usually prolonged and/or high-dose, use of that substance. G2. Symptoms and signs are compatible with the known features of a withdrawal state from the particular substance or substances (see below). G3. Symptoms and signs are not accounted for by a medical disorder unrelated to substance use, and not better accounted for by another mental or behavioural disorder.

F1x.6 Amnesic syndrome

A. Memory impairment is manifest in both: (1) a defect of recent memory (impaired learning of new material) to a degree sufficient to interfere with daily living; and (2) a reduced ability to recall past experiences.

C. There is no objective evidence from physical and neurological examination, laboratory tests, or history of a disorder or disease of the brain (especially involving bilaterally the diencephalic and medial temporal structures), other than that related to substance use, that can reasonably be presumed to be responsible for the clinical manifestations described under criterion A.

residual states or conditions should be clearly documented in terms of their type,
severity, and duration. For research purposes full descriptive details should be
specified.
