Summary
Women who use crack cocaine exhibit higher impulsivity and impaired inhibitory control compared to healthy individuals. These findings highlight a strong link between crack use and deficits in self-control.
Area of Science:
- Neuroscience
- Psychology
- Addiction Studies
Background:
- Crack cocaine use is a significant public health issue, particularly among women.
- Understanding the neurocognitive correlates of addiction, such as impulsivity and inhibitory control, is crucial for developing effective interventions.
Purpose of the Study:
- To investigate impulsivity and inhibitory control in women who use crack cocaine.
- To explore the relationship between impulsivity and inhibitory control in this population.
Main Methods:
- A quantitative, cross-sectional study with a control group.
- Participants included 46 women who use crack cocaine (in abstinence) and 52 healthy women.
- Assessments included the Barratt Impulsiveness Scale-11 (BIS-11) and a Go/No-Go Task.
Main Results:
- Crack cocaine users displayed significantly higher impulsivity levels across all domains compared to the control group.
- Crack users made more commission and omission errors on the Go/No-Go task, indicating poorer inhibitory control.
- Significant correlations between inhibitory control measures and impulsivity were found exclusively within the crack cocaine user group.
Conclusions:
- Impulsivity and impaired inhibitory control are closely associated with crack cocaine use in women.
- Future research should examine the influence of varying abstinence periods on these neurocognitive functions in crack users.

1.8K
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...

01:27CNS Depressants: Alcohol and Nicotine
1.4K
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...

01:15Drug Abuse and Addiction: Pharmacological Phenomena
1.3K
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...

1.1K
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms

01:21Drugs Affecting Neurotransmitter Release or Uptake
1.7K
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...

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.
