ALCOHOL

Overview

Ethyl alcohol (ethanol) is recognized as the active psychoactive ingredient present within alcoholic beverages.
Standard alcoholic beverages typically contain approximately 18 ml (12 grams) of pure alcohol; this is equivalently found in:
  - A 12 oz beer
  - A 5 oz glass of wine
  - A 1.5 oz serving of liquor.
Beer is characterized by an alcohol content usually ranging from 4% to 6%, produced through the fermentation process of various cereal grains.
Beer is noted as the third most consumed beverage globally.
Following the consumption of a single drink, alcohol peaks in blood concentration within around 30 minutes, with metabolism occurring in the liver at an approximate rate of one standard drink per hour.
Ethanol is acknowledged as the most widely used psychoactive substance and is among the most ancient known.

Statistics

In the United States:
  - Approximately 50% to 66% of adults over the age of 12 self-identify as current drinkers.
  - 22.6% reported experiencing a binge drinking episode (5 or more drinks) within the past month.
  - 42% of college students reported a binge episode in the two weeks preceding the survey.
Findings from Hasin et al. (2007):
  - Lifetime prevalence of Alcohol Use Disorder (AUD) stands at 12.5%.
  - Higher rates of AUD are observed among White and Native American populations, as well as among men and individuals of low socio-economic status (SES).
  - Only 24.1% of affected individuals receive treatment.

Alcohol Use Disorder

Alcohol Use Disorder can be described by a problematic pattern of alcohol use that leads to clinically significant impairment or distress, identified by at least two of the following criteria during a 12-month period:
  1. Alcohol is consumed in larger amounts or over a longer period than initially intended.
  2. There is a persistent desire or unsuccessful efforts to decrease alcohol consumption.
  3. Substantial time is allocated to activities required to procure, use, or recover from alcohol consumption.
  4. Cravings for alcohol.
  5. Failure to meet major role obligations due to alcohol use.
  6. Continued use despite recurrent interpersonal or social problems caused by alcohol consumption.
  7. Cessation of significant social, occupational, or recreational activities because of alcohol use.
  8. Recurrent alcohol use in physically hazardous situations.
  9. Ongoing alcohol use despite awareness of negative consequences.
  10. Development of tolerance.
  11. Presence of withdrawal symptoms.

Alcohol Intoxication

Defined by the recent ingestion of alcohol, and characterized by:
- Clinically significant behavioral or psychological changes that occur during or shortly after consumption, including inappropriate behaviors, mood swings, or impaired judgment.
One or more specific symptoms should manifest within the alcohol consumption duration:
  1. Slurred speech.
  2. Coordination issues.
  3. Unsteady gait.
  4. Nystagmus (rapid, involuntary eye movement).
  5. Impairment in attention or memory.
  6. Stupor or coma.
It is essential to differentiate these symptoms from other medical conditions or mental disorders.
Relevant coding:
  - ICD-9-CM code: 303.00.
  - ICD-10-CM codes vary based on the presence or absence of a comorbid alcohol use disorder. Common codes include:
    - F10.129 for mild AUD
    - F10.229 for moderate or severe AUD
    - F10.929 for individuals without AUD.

Alcohol Withdrawal

Diagnostic criteria require:
  A. Cessation or reduction in heavy and prolonged alcohol use.
  B. Develop two or more of the following within several hours to a few days after cessation of use:
  1. Autonomic hyperactivity (such as sweating or a pulse rate that exceeds 100 bpm).
  2. Increased hand tremors.
  3. Insomnia.
  4. Nausea or vomiting.
  5. Transient hallucinations or illusions.
  6. Psychomotor agitation.
  7. Anxiety.
  8. Generalized tonic-clonic seizures.
  C. The symptoms must lead to clinically significant distress or impairment in daily functioning.
  D. Exclusion of alternative medical conditions or mental disorders.
Additional specifications include:
- With perceptual disturbances, when hallucinations occur with reality testing intact.
Relevant coding:
- ICD-9-CM code: 291.81.
- ICD-10-CM codes depend on the presence of perceptual disturbances (F10.239 for without, F10.232 for with disturbances). Note the requirement for associated moderate or severe AUD.

Alcohol-related Comorbidities

Include disorders such as:
  - Alcohol-Induced Psychotic Disorders
  - Alcohol-Induced Affective Disorders
  - Alcohol-Induced Anxiety Disorders
  - Alcohol-Induced Sexual Dysfunction
  - Alcohol-Induced Sleep Disorders

Medical Complications of Alcohol

Significant health implications can affect various systems, including:
  - Liver complications
  - Auswirkungen auf Magen-Darm-Trakt und Bauchspeicheldrüse
  - Cardiovascular health risks
  - Risk of cancer
  - Effects on hematologic conditions
  - Immune system dysfunction
  - Musculoskeletal issues
  - Skin disorders
  - Fetal alcohol syndrome in offspring.

Korsakoff's Psychosis

A significant psychological condition associated with alcohol misuse characterized by:
- Initial hemorrhage into the mammillary bodies, followed later by atrophy of the same areas.
The implications of this syndrome can severely affect memory and cognitive functioning.

Behavioral Aspects: Classical Conditioning and Tolerance

The role of classical conditioning in the development of alcohol tolerance and dependence offers insights into behavioral therapies aimed at treating AUD.

Case Study: Steve

Primary diagnosis: Alcohol Use Disorder, Severe.
Family History: Multiple biological relatives with alcohol dependence, a background of domestic violence.
Personal History: Initiated alcohol consumption at 18 years, experienced two marriages and two divorces, has four children (two with each partner), and was court-ordered to seek treatment following a DUI arrest.

Individual Psychosocial Treatment

Inquiry into positive and negative reinforcing effects of alcohol:
- Positive effects: temporary escape from stress or enjoying social interactions.
- Negative effects: potential feelings of regret or negative social consequences of heavy drinking.
Exploration of unhelpful automatic thoughts (often cognitive distortions) that might affect Steve’s recovery, and how they could be addressed through behavioral cognitive techniques.

Group/Individual Treatment: Relapse Prevention

Critical assessments to identify risk factors that could lead to relapse:
  1. Situational triggers or emotional states that prompt drinking.
  2. Thoughts regarding drinking, or perceptions of its consequences.
  3. Benefits of drinking perceived by the individual.
  4. Detriments associated with drinking behavior.

Coping Self-Statements

Development of positive coping self-statements, such as identifying the impermanence of drinking urges.
Recognition of detrimental impacts of alcohol use, e.g., relationship damage and job loss.
Identification of benefits from sobriety, like improved family bonds and financial savings.
Focus on alternative activities to combat feelings of boredom, emphasizing engagement with children or social outings.
Challenging misbeliefs surrounding alcohol, such as needing alcohol to enjoy social events or to express creativity.

Group Treatment: Alcoholics Anonymous (and Similar Programs)

Central principles of Alcoholics Anonymous (AA) include:
  - Embracing total abstinence as the primary goal.
  - Engagement with a higher power as a source of strength.
  - The view that alcoholism is a disease more powerful than individual will.
  - Involvement of peers in guiding the treatment process rather than clinicians.
Overview of the Twelve Steps of AA, which include:
  1. Admission of powerlessness over alcohol.
  2. Belief in a higher power that can restore wellbeing.
  3. Decision to surrender life to the higher power.
  4. Thorough moral inventory-taking.
  5. Acknowledgment of wrongdoings to oneself and others.
  6. Preparedness to let the higher power remove personal character flaws.
  7. Request for the higher power to intervene regarding these flaws.
  8. List of individuals to whom amends should be made.
  9. Actual making of these amends.
  10. Continuation of personal inventory and correction of errors as they occur.
  11. Enhancement of contact with the higher power through prayer.
  12. Achieving spiritual awakening and sharing the message with other alcoholics.

Motivation & Recovery

Evidence supports the effectiveness of cognitive-behavioral therapy (CBT) combined with support groups akin to AA. However, the success heavily relies on the patient’s motivation for recovery.
Strategies for addressing patients lacking motivation for abstinence can involve motivational interviewing techniques, aiming to align the patient's goals with necessary recovery processes.
