Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

238
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.

Drug Dependence01:17

Drug Dependence

1.2K
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...

Diagnostic and Statistical Manual of Mental Disorders (DSM)01:27

Diagnostic and Statistical Manual of Mental Disorders (DSM)

275
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...

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

CNS Depressants: Alcohol and Nicotine01:27

CNS Depressants: Alcohol and Nicotine

562
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...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

393
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...

Area of Science:

  • Neuroscience
  • Public Health
  • Pharmacology

Background:

  • Tobacco use disorder (TUD) is a global health crisis affecting over a billion individuals.
  • The addictive nature of tobacco is often underestimated, masking complex neural adaptations.
  • Nicotine's behavioral effects contribute to substantial lifelong morbidity.

Purpose of the Study:

  • To highlight the underappreciated complexity of nicotine addiction.
  • To discuss the impact of innovative tobacco processing and delivery systems.
  • To review current and future pharmacotherapeutic interventions for TUD.

Main Methods:

  • Review of current literature on tobacco use disorder.
  • Analysis of neurobiological mechanisms underlying nicotine addiction.
  • Examination of pharmacotherapeutic strategies and emerging treatments.

Main Results:

  • Nicotine induces profound and lasting neural adaptations.
  • Modern tobacco products are increasingly potent, exacerbating addiction.
  • Pharmacotherapy offers effective treatment avenues for TUD.

Conclusions:

  • Addressing TUD requires acknowledging its complex neurobiology and addictive potential.
  • Innovative treatments, including phenotypically tailored pharmacotherapies, are crucial.
  • Preventive strategies are essential to curb future generations' tobacco use.
