Management of Insomnia01:19

Management of Insomnia

747
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...

Insomnia

563
Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

Sedatives and Hypnotics Drugs: Miscellaneous Agents01:17

Sedatives and Hypnotics Drugs: Miscellaneous Agents

748
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...

CNS Depressants: Barbiturates and Benzodiazepines01:14

CNS Depressants: Barbiturates and Benzodiazepines

1.5K
CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...

Sedatives and Hypnotics: Overview

1.8K
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...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

502
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.
Understanding the concepts of physical dependence,...

Area of Science:

  • Behavioral Science
  • Sleep Medicine
  • Digital Health

Background:

  • Insomnia is a prevalent condition linked to reduced quality of life and increased healthcare usage.
  • Cognitive Behavioral Therapy (CBT) is effective for insomnia but faces accessibility and cost barriers.
  • Web-based CBT presents a potential solution to overcome these limitations.

Purpose of the Study:

  • To evaluate the efficacy of an online CBT and stress management program for insomnia.
  • To assess the program's effectiveness in adults with primary insomnia.
  • To analyze outcomes in adults with comorbid insomnia.

Main Methods:

  • A randomized controlled trial was conducted with adults experiencing primary insomnia (n=88).
  • A 6-week online intervention program was delivered, with effectiveness measured by the Insomnia Severity Index (ISI).
  • Adults with comorbid insomnia (n=263) were analyzed separately.

Main Results:

  • The intervention group showed a statistically significant reduction in ISI scores (-7.3) compared to the control group (-1.3).
  • Improvements were sustained at follow-up, indicating lasting effects of the online CBT program.
  • Participants with comorbid insomnia also experienced significant improvements, similar to those with primary insomnia.

Conclusions:

  • Online CBT for insomnia yields clinically meaningful improvements in insomnia severity.
  • The sustained positive outcomes highlight the effectiveness of well-designed digital CBT interventions.
  • This approach enhances accessibility to effective insomnia treatment.
