CNS Stimulants: Psychedelic Agents

CNS Stimulants: Psychedelic Agents

Hallucinogens, also known as psychedelic drugs, are a class of substances known for their ability to alter perception, cognition, and emotions. Despite their profound effects on the mind, these drugs are non-addictive, setting them apart from many other abused substances. The mechanism of action of these drugs lies in their impact on the 5-HT2A receptor in the brain. Upon activation, this receptor couples to Gq-type G proteins, triggering a cascade that releases intracellular calcium. This...

Hallucinogens and Psychedelics

Hallucinogens and Psychedelics

Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.
Marijuana, derived from the dried leaves and flowers of the hemp plant, contains delta-9-tetrahydrocannabinol (THC)...

Positive Symptoms Schizophrenia: Hallucinations and Delusions

Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...

Stimulants

Stimulants

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...

Altered States of Awareness

Altered States of Awareness

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 that...

Summary

This summary is machine-generated.

Visual hallucinations are a rare side effect of methylphenidate (MPH) treatment for attention deficit/hyperactivity disorder (ADHD). This case highlights the importance of considering MPH as a potential cause for hallucinations in pediatric patients.

Background:

Attention deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children.
Methylphenidate (MPH) is a widely prescribed stimulant medication for managing ADHD symptoms.
Stimulant medications like MPH primarily work by increasing dopamine and norepinephrine levels in the brain.

Observation:

An 11-year-old boy diagnosed with ADHD experienced visual hallucinations.
These hallucinations emerged several years into his treatment with MPH.
The visual hallucinations ceased after MPH was discontinued.

Findings:

This case report documents a rare instance of toxic hallucinosis associated with therapeutic MPH doses.
The proposed mechanism involves a potential chronic increase in synaptic dopamine levels.
Hallucinations are an uncommon but possible adverse effect of MPH treatment.

Implications:

Clinicians prescribing MPH for ADHD should be vigilant for potential visual hallucinations.
Discontinuation of MPH may lead to the resolution of drug-induced hallucinations.
Further research into the neurobiological mechanisms underlying MPH-induced hallucinations is warranted.
