Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

257
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,...

CNS Depressants: Alcohol and Nicotine

628
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...

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

182
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Area of Science:

  • Neuroscience
  • Psychology
  • Addiction Research

Background:

  • Time perception is influenced by attentional, executive, and memory processes.
  • Alcohol consumption is known to affect these cognitive functions.
  • Understanding alcohol's impact on time perception is crucial for cognitive and addiction research.

Purpose of the Study:

  • To systematically review and critically assess existing literature on time perception in individuals who consume alcohol.
  • To analyze the effects of different patterns of alcohol consumption (intoxication, heavy drinking, severe alcohol use disorder, Korsakoff syndrome) on time perception.
  • To identify methodological limitations and propose future research directions.

Main Methods:

  • Systematic literature review adhering to PICOS and PRISMA guidelines.
  • Selection of 31 relevant articles across four distinct alcohol-related populations.
  • Critical assessment of study methodologies and reported findings on time perception.

Main Results:

  • Alcohol intoxication may lead to either overestimation or underestimation of time.
  • Binge/heavy drinking showed no direct effect on time perception.
  • Severe alcohol use disorder (SAUD) yielded conflicting results; Korsakoff syndrome demonstrated globally impaired time perception and cognitive deficits.

Conclusions:

  • Alcohol consumption appears to affect time perception primarily when underlying cognitive processes are compromised.
  • Methodological limitations in current studies prevent definitive conclusions.
  • Further research with improved methodologies is needed to clarify the relationship between alcohol and time perception.
