Sedatives and Hypnotics: Overview01:23

Sedatives and Hypnotics: Overview

Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives and Hypnotics Drugs: Miscellaneous Agents

Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
Altered States of Awareness01:06

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...
Sedatives and Hypnotics Drugs: Benzodiazepines01:19

Sedatives and Hypnotics Drugs: Benzodiazepines

Benzodiazepines have both sedative and hypnotic properties. They include compounds such as diazepam (Valium) and alprazolam (Xanax). Structurally, their cores are similar, consisting of the fusion of a benzene ring and a diazepine ring, but they share a common mechanism of action in the central nervous system (CNS).
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
Management of Insomnia01:19

Management of Insomnia

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
Sedatives and Hypnotics Drugs: Barbiturates01:20

Sedatives and Hypnotics Drugs: Barbiturates

Sedatives and hypnotics encompass a drug class that acts on the central nervous system (CNS) to alleviate anxiety, promote relaxation and induce sleep.These drugs function by amplifying the actions of the neurotransmitter γ-aminobutyric acid (GABA), resulting in reduced neuronal activity. Barbiturates, a subset of sedatives and hypnotics first synthesized in the late 1800s, are categorized into ultra-short, short, intermediate, and long-acting groups based on their duration of effect. A key...

Summary
This summary is machine-generated.

Hypnotizability, a measure of susceptibility to hypnosis, is linked to both regular daytime sleepiness and immediate sleepiness post-hypnosis. Subjective reports of hypnotic experiences can complement sleepiness assessments.

Area of Science:

  • Psychology
  • Neuroscience
  • Sleep Science

Background:

  • Hypnotizability is a key individual difference in hypnotic responsiveness.
  • Sleepiness, encompassing both habitual and instantaneous states, can influence cognitive and subjective experiences.
  • Understanding the interplay between hypnotizability and sleepiness is crucial for research on consciousness and suggestion.

Purpose of the Study:

  • To investigate the relationship between hypnotizability and various measures of sleepiness.
  • To explore the correlation between hypnotizability and the subjective experience of hypnotic suggestions.
  • To assess the utility of a self-developed questionnaire for evaluating subjective hypnotic experiences.

Main Methods:

  • Ninety participants completed the Harvard Group Scale of Hypnotic Susceptibility Form A (HGSHS:A).
  • Sleepiness was assessed using the Karolinska Sleepiness Scale (KSS) and Epworth Sleepiness Scale (ESS).
  • Sleep quality was measured by the Pittsburgh Sleep Quality Index (PSQI), and subjective hypnotic experiences by the Questionnaire on Subjective Hypnotic Experiences (QSHE).

Main Results:

  • A significant correlation was found between hypnotizability and habitual daytime sleepiness (ESS).
  • Hypnotizability also correlated with instantaneous sleepiness measured after the hypnotic procedure (KSS).
  • The Questionnaire on Subjective Hypnotic Experiences (QSHE) showed potential utility in complementing other subjective scales, particularly those related to sleepiness.

Conclusions:

  • Hypnotizability is associated with an individual's general tendency towards daytime sleepiness.
  • Sleepiness levels, both before and immediately after hypnosis, are related to one's hypnotizability.
  • Subjective self-assessment of responses to hypnotic suggestions can provide valuable insights, especially when compared with sleepiness measures.
