Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

1.5K
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

1.9K
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 Sleep

547
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,...

Diagnostic and Statistical Manual of Mental Disorders (DSM)

1.7K
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...

Stimulants01:29

Stimulants

1.3K
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...

Binge Eating Disorders01:23

Binge Eating Disorders

763
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

    Summary

    This study reveals that excessive computer gaming decreases prefrontal cortex activity, potentially causing damage. Research in South Korea, China, and Japan highlights these concerning trends in gaming behavior.

    Area of Science:

    • Neuroscience
    • Cognitive Science
    • Psychology

    Context:

    • Comparative analysis of computer game research in South Korea, China, and Japan.
    • Investigation into the neurological effects of excessive gaming behavior.

    Purpose:

    • To analyze the current state of computer game research in South Korea, China, and Japan.
    • To examine the impact of excessive game actions on prefrontal cortical activity using neuroimaging techniques.

    Summary:

    • Neuroimaging studies (PET-MRI, MRI, fMRI, NIRS, EEG) indicate reduced prefrontal cortical activity during gameplay.
    • Game addiction is associated with damage to the prefrontal cortex.
    • Simultaneous NIRS-EEG recordings show decreased beta band activity and oxygen-hemoglobin levels during gameplay, while alpha band remained unchanged.
