Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

507
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,...

Drugs Acting on Autonomic Ganglia: Stimulants01:23

Drugs Acting on Autonomic Ganglia: Stimulants

2.2K

Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

1.1K
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...

Toxidromes: Clinical Features

72
Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...

Altered States of Awareness01:06

Altered States of Awareness

1.4K
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...

Stimulants01:29

Stimulants

1.1K
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...

Area of Science:

  • Neuroscience
  • Addiction Research
  • Brain Imaging

Background:

  • Drug addiction, particularly heroin addiction, is a significant global health issue.
  • Neuroimaging studies reveal that specific brain regions are vulnerable to heroin addiction.
  • These regions are crucial for reward, motivation, memory, inhibition, and emotional control, forming interconnected circuits.

Purpose of the Study:

  • To comprehensively review resting-state neuroimaging findings in heroin addiction.
  • To classify findings into functional connectivity, structural deficits, and topological properties.
  • To discuss behavioral traits and limitations in current addiction research.

Main Methods:

  • Review of existing resting-state neuroimaging studies.
  • Classification of findings into functional connectivity, structural deficits, and topological properties.
  • Analysis of behavioral traits and study limitations.

Main Results:

  • Identified alterations in functional connectivity, structural integrity, and topological organization of brain networks in heroin addiction.
  • Highlighted the involvement of prefrontal, parietal, occipital, temporal, and subcortical regions.
  • Discussed behavioral characteristics associated with heroin addiction.

Conclusions:

  • Resting-state neuroimaging provides insights into the complex brain alterations in heroin addiction.
  • A multimodal therapeutic approach combining traditional methods with neurotechnologies is recommended.
  • Future research should address limitations and explore novel treatment strategies like neurofeedback and gamification.
