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: 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: 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...
Stages of General Anesthesia01:22

Stages of General Anesthesia

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...
Sedatives and Hypnotics Drugs: Miscellaneous Agents01:17

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...
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...

Area of Science:

  • Psychology
  • Psychiatry
  • Behavioral Medicine

Background:

  • Hypnotherapy is a therapeutic technique with a long history.
  • Its efficacy across various psychological and medical conditions requires systematic evaluation.
  • Evidence-based practice necessitates rigorous assessment of treatment effectiveness.

Purpose of the Study:

  • To systematically review and evaluate the efficacy of hypnotic treatments.
  • To identify specific disorders for which hypnosis is an effective or specific intervention.
  • To provide clinicians with evidence-based guidance on using hypnotherapy.

Main Methods:

  • Conducted a comprehensive review of 18 major meta-analyses on hypnotic treatments.
  • Evaluated the findings using the established criteria of Chambless & Hollon (1998).
  • Synthesized data to determine the level of evidence for hypnosis in treating various disorders.

Main Results:

  • Identified 32 disorders where hypnosis may be considered a potential treatment.
  • Found evidence supporting the effectiveness of hypnosis for 5 specific disorders.
  • Determined that hypnosis appears to be a specific treatment for 2 disorders.

Conclusions:

  • Hypnosis is a potentially efficacious treatment for a range of conditions.
  • Clinicians should consider using hypnosis for disorders where evidence of efficacy exists.
  • Further research and systematic application can expand the recognized therapeutic applications of hypnosis.
