Introduction
- Alcohol and drug misuse is not limited to one particular specialty.
- Alcohol and drug use are relevant to psychiatric practice.
- Relevant in cases of patients with acute confusion or emergencies, elderly patients, or troubled adolescents.
- Includes cases of patients with self care deterioration, or disturbed children inhaling volatile substances.
Classification of Substance Use Disorders
- DSM-5 and ICD-10 use similar categories for substance use disorders.
- Both systems categorize substance use disorders, intoxication, and withdrawal states.
- ICD-10 has separate categories for "harmful use" and "dependence".
- DSM-5 combines "harmful use" and "dependence" into one category called "use disorder".
- Severity of substance use disorder is based on a number of features, not separate categories for "drug dependence".
- Drug-induced psychotic states and amnestic states are coded in the other mental and behavioral disorders in ICD-10 but not in DSM-5.
- Alcohol-induced psychotic disorders are also coded differently in ICD-10 than DSM-5.
- The most important substance use is the basis for diagnosis.
- "Disorder due to multiple drug use" is a category used in ICD-10.
- The relevant disorder is added to the substance misuse description.
- Some drugs (hallucinogens) do not have a recognized withdrawal syndrome.
