Summary
Substance abuse disorders and overdose deaths are rising, especially during COVID-19. Understanding how drugs affect brain neurotransmission is key to developing new addiction treatments.
Area of Science:
- Neuroscience
- Addiction Research
- Pharmacology
Background:
- Substance abuse disorders (SAD) and drug-related overdose deaths have increased significantly, exacerbated by the COVID-19 pandemic.
- Neurotransmitter system dysregulation in the brain is a critical factor in the development and expression of addiction.
- Recent scientific progress has enhanced our understanding of the neurobiological underpinnings of drug addiction.
Purpose of the Study:
- To review classic and recent findings on how various drugs of abuse impact neurotransmitter systems.
- To explore the interactive effects of substance abuse with HIV-1 and COVID-19 on neurobiology.
- To introduce potential therapeutic strategies for pharmacotherapies targeting substance abuse disorders.
Main Methods:
- Review of clinical observations and neuroimaging studies.
- Analysis of neuropsychological performance testing data.
- Synthesis of current scientific literature on neurobiology of addiction.
Main Results:
- Cocaine, amphetamines, opioids, alcohol, and nicotine alter multiple neurotransmitter systems, contributing to drug-specific behaviors.
- Substance abuse interacts with HIV-1 and COVID-19, affecting neurotransmission and neurobiological pathways.
- Understanding these neurobiological changes is crucial for developing effective treatments.
Conclusions:
- Neurobiological insights into substance abuse are advancing rapidly.
- Pharmacotherapies for substance abuse disorders can be developed based on understanding drug-induced neurotransmitter alterations.
- Addressing the complex interplay between pandemics and substance abuse is vital for public health.

01:15Drug Abuse and Addiction: Pharmacological Phenomena
766
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...

01:24Substance Use Disorders Affecting Sleep
234
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.

01:26Neurochemical Transmission: Sites of Drug Action
2.7K
Neurochemical transmission, the conduction of electrical impulses between neurons mediated by neurotransmitters, plays a vital role in various physiological processes. Autonomic drugs exert their effects by modulating neurotransmission within the autonomic nervous system. For instance, drugs such as hemicholinium block the precursor uptake necessary for synthesizing acetylcholine, an essential autonomic neurotransmitter. Following synthesis, neurotransmitters are stored in vesicles. Metyrosine...

01:29Excitatory and Inhibitory Effects of Neurotransmitters
10.9K
When an action potential reaches the presynaptic axon terminal, it releases neurotransmitters from the neuron into the synaptic cleft at a chemical synapse. The released neurotransmitter can be excitatory or inhibitory. The critical criteria commonly used to determine whether a molecule is a neurotransmitter at a chemical synapse are the molecule's presence in the presynaptic neuron. Second, its release is in response to strong presynaptic depolarization. And lastly, the presence of...

01:21Drugs Affecting Neurotransmitter Release or Uptake
1.3K
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...

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...
