Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

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 necessarily...
Drug Dependence01:17

Drug Dependence

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 Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its effects by...
Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

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,...
Obsessive-Compulsive Disorder01:28

Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...
Stimulants01:29

Stimulants

Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Summary

A significant portion of cocaine-dependent patients exhibit compulsive behaviors, not just impulsivity. Neuropsychological testing reveals compulsive cocaine users struggle with perseverance and decision-making.

Area of Science:

  • Neuroscience
  • Behavioral Psychology
  • Addiction Research

Context:

  • Addiction is theorized as a dynamic behavioral change on the impulsivity-compulsivity axis.
  • Distinguishing between impulsive and compulsive addiction subtypes remains challenging.
  • Understanding these subtypes is crucial for targeted addiction treatment strategies.

Purpose:

  • To categorize cocaine-dependent patients (CDI) as primarily impulsive or compulsive.
  • To assess the association between these categories and trait impulsivity.
  • To examine the relationship between impulsivity/compulsivity and cocaine addiction severity.

Summary:

  • Neuropsychological tests (Stroop, Go/No Go, Revised-Strategy Application, Probabilistic Reversal) and the UPPS-P scale were used to assess 42 CDI and 65 healthy controls.
  • 45% of CDI were classified as compulsive, showing higher scores in lack of perseverance and premeditation on the UPPS-P.
  • Compulsive CDI were less perseverative and more prone to under-meditated decisions, but no differences in cocaine exposure severity were found compared to impulsive CDI.

Impact:

  • A substantial subgroup of cocaine-dependent patients can be identified as compulsive based on neuropsychological performance.
  • This classification correlates with specific trait impulsivity dimensions, suggesting distinct underlying mechanisms.
  • Findings may inform personalized treatment approaches for cocaine addiction by differentiating between impulsive and compulsive profiles.
