Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

759
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

1.2K
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...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

228
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,...

Stimulants01:29

Stimulants

361
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...

Social Foundations of Self IV: Self in Digital Communication

3
Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

Bullying

8.5K
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Area of Science:

  • Neuroscience
  • Psychiatry
  • Behavioral Science

Background:

  • Problematic internet use (PIU) is a growing concern with significant public health implications.
  • PIU exhibits behavioral and neurobiological similarities to substance use disorders (SUDs).
  • The precise neurobiological mechanisms underlying PIU are not yet fully elucidated.

Purpose of the Study:

  • To investigate the neurobiological underpinnings of problematic internet use.
  • To compare the neural correlates of PIU with those of established addictions.
  • To identify potential therapeutic targets for PIU.

Main Methods:

  • Utilizing functional magnetic resonance imaging (fMRI) to examine brain activity in individuals with PIU.
  • Employing behavioral assessments and validated questionnaires to characterize PIU severity.
  • Comparing brain activation patterns during reward-related tasks between PIU and control groups.

Main Results:

  • Preliminary findings suggest altered reward pathway activation in individuals with PIU.
  • Observed differences in prefrontal cortex activity during decision-making tasks.
  • Correlations between PIU severity and specific patterns of neural connectivity.

Conclusions:

  • Problematic internet use may involve dysregulation of brain circuits similar to those affected in drug addiction.
  • These findings highlight the need for addiction-focused interventions for PIU.
  • Further research is warranted to confirm these mechanisms and explore treatment strategies.
