Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

311
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.

Stress and Mental Health

387
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
Individuals with depression often experience challenges in both their personal and professional...

Drug Abuse and Addiction: Pharmacological Phenomena

975
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...

Drug Dependence

1.4K
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...

CNS Depressants: Alcohol and Nicotine

849
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...

Drug Therapy01:28

Drug Therapy

185
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Area of Science:

  • Public Health
  • Addiction Medicine
  • Sociology

Background:

  • The COVID-19 pandemic caused widespread health and economic disruption.
  • Individuals with substance use disorders (SUDs) faced disproportionate impacts due to the intersection of SUDs and the pandemic.
  • Pre-existing comorbidities and high-risk environments associated with SUDs likely increased COVID-19 vulnerability.

Purpose of the Study:

  • To examine the direct and indirect effects of the COVID-19 pandemic and systemic shock on individuals with SUDs.
  • To advocate for an interdisciplinary and international perspective on SUDs and pandemic impacts.
  • To highlight the need for understanding SUDs as biopsychosocial disorders and implementing evidence-based, destigmatizing policies.

Main Methods:

  • Interdisciplinary review of existing literature and data.
  • International perspective synthesis.
  • Policy analysis and recommendation development.

Main Results:

  • The pandemic diminished essential resources for SUD recovery and well-being.
  • Comorbidities and risk environments linked to SUDs are associated with increased COVID-19 risk.
  • Systemic shocks necessitate a reevaluation of addiction care systems.

Conclusions:

  • SUDs require recognition as complex biopsychosocial disorders.
  • Evidence-based policies are essential to combat stigma surrounding SUDs.
  • Strengthening and modernizing addiction care systems is vital for future resilience against pandemics and other systemic shocks.
