Summary
Methamphetamine dependence causes brain dysfunction, particularly in areas controlling behavior. Abstinence reveals abnormalities in neurotransmitter systems and cognitive deficits, impacting relapse prevention.
Area of Science:
- Neuroscience
- Addiction Research
- Cognitive Psychology
Background:
- Methamphetamine dependence is a chronic relapsing condition.
- Understanding the neurobiological underpinnings of methamphetamine abuse is crucial for effective treatment.
Purpose of the Study:
- To review and interpret evidence linking methamphetamine dependence to brain functional disorders.
- To explore how these brain function disorders impact top-down behavioral control.
Main Methods:
- Analysis of findings from human brain imaging studies.
- Focus on participants with histories of chronic methamphetamine abuse.
- Contextualization within functional consequences and treatment implications.
Main Results:
- Chronic methamphetamine abuse is associated with brain abnormalities in abstinent individuals compared to controls.
- Observed deficits in dopaminergic and serotonergic systems, glucose metabolism, and gray matter volume.
- Cognitive impairments, including reduced inhibitory control, accompany these neurobiological changes.
Conclusions:
- Cortical deficits in abstinent methamphetamine users impair functions vital for maintaining abstinence.
- These deficits affect responses to stimuli and internal triggers, contributing to craving and relapse.
- Combined behavioral therapies and cognitive-enhancing medications show promise for treatment.

01:15Drug Abuse and Addiction: Pharmacological Phenomena
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 necessarily...
01:30Attention-Deficit/Hyperactivity Disorder
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
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.

01:24CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
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 effects by...
01:25Adrenergic Agonists: Indirect-Acting Agents
Indirect-acting adrenergic agonists potentiate the effects of endogenous catecholamines through different mechanisms without directly binding to adrenoceptors.
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...

01:29Stimulants
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...

01:27Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...
