CNS Depressants: Alcohol and Nicotine01:27

CNS Depressants: Alcohol and Nicotine

1.6K
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Substance Use Disorders Affecting Sleep

538
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Diagnostic and Statistical Manual of Mental Disorders (DSM)

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Drug Dependence01:17

Drug Dependence

1.9K
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Drug Abuse and Addiction: Pharmacological Phenomena

1.5K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Depressive Disorders: Etiology01:27

Depressive Disorders: Etiology

859
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...

Summary

Long-term abstinent alcoholics (LTAA) maintain sobriety despite psychiatric issues, but often experience psychological distress. Addressing these comorbid mental health problems is crucial for improving their quality of life.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Neuroscience

Background:

  • Psychiatric comorbidity is common in individuals with alcohol use disorders.
  • Understanding the long-term mental health impact of abstinence is crucial for effective treatment.
  • Previous research often excludes individuals with psychiatric diagnoses, potentially overlooking subdiagnostic differences.

Purpose of the Study:

  • To investigate psychiatric comorbidity in treatment-naïve alcoholics (TNA), short-term abstinent alcoholics (STAA), and long-term abstinent alcoholics (LTAA).
  • To examine the persistence of psychiatric symptoms and antisocial behaviors during abstinence.
  • To assess the psychological distress experienced by LTAA compared to non-alcoholic controls (NAC).

Main Methods:

  • Review of clinical studies comparing TNA, STAA, and LTAA with NAC.
  • Assessment of lifetime psychiatric diagnoses, including mood, anxiety, borderline personality disorder (BPD), and antisocial personality disorder (ASPD).
  • Evaluation of psychological symptoms and abnormal psychological measures in abstinent and non-abstinent alcoholic populations.

Main Results:

  • TNA generally exhibit less severe alcoholism and psychiatric disturbance than abstinent groups.
  • Lifetime psychiatric diagnoses are common in STAA and LTAA, but not TNA.
  • LTAA demonstrate a significant reduction in antisocial behaviors to levels comparable to controls, while mood, anxiety, and BPD symptoms may persist.
  • Abstinent individuals, even without lifetime diagnoses, show more subdiagnostic psychiatric symptoms than NAC.
  • LTAA report significant psychological distress compared to NAC, despite achieving long-term abstinence.

Conclusions:

  • Alcoholics can achieve and maintain abstinence with ongoing mood, anxiety, or BPD issues.
  • Ongoing antisocial behavior appears inconsistent with maintaining abstinence.
  • LTAA experience persistent psychological distress, highlighting the need for integrated care models for comorbid mental health conditions.
  • Excluding individuals with psychiatric diagnoses in research does not fully account for subdiagnostic psychiatric differences.
