Nightmares and Night Terrors01:18

Nightmares and Night Terrors

671
Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

Insomnia01:27

Insomnia

560
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.

Sleepwalking and Sleep Talking01:17

Sleepwalking and Sleep Talking

1.2K
Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

501
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,...

Sleep Apnea01:21

Sleep Apnea

670
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

2.2K
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Summary
This summary is machine-generated.

Mental health screens can be improved by including measures of sleep difficulties and anger. These factors help predict post-traumatic stress disorder (PTSD) and alcohol use in military personnel after deployment.

Area of Science:

  • Military mental health
  • Psychological screening

Background:

  • Mental health screens aim to identify individuals at risk for psychological disorders like PTSD and alcohol use.
  • Deployment-related mental health is a critical concern for military personnel.
  • Existing screening methods may benefit from incorporating additional predictive factors.

Purpose of the Study:

  • To investigate the predictive validity of sleep difficulties and anger in relation to postdeployment PTSD and alcohol use.
  • To determine if these factors offer incremental validity to existing mental health screening measures.
  • To inform the design of interventions for returning military personnel.

Main Methods:

  • A cohort of 212 military personnel completed pre- and post-deployment assessments.
  • Measures included PTSD Checklist-Civilian (PCL-C), Kessler 10, Sleep Difficulties scale, anger scale, and Alcohol Use Disorders Identification Test (AUDIT).
  • Hierarchical regression analyses were used to assess predictive validity.

Main Results:

  • Pre-deployment measures predicted 24.4% of postdeployment PTSD variance and 13.1% of alcohol use variance.
  • Sleep difficulties significantly contributed to predicting PTSD scores.
  • Anger contributed to predicting alcohol use scores.

Conclusions:

  • Inclusion of anger and sleep difficulty measures in end-of-deployment mental health screens is recommended.
  • Sleep difficulties are a valuable addition to screening due to correlation with PTSD and low stigma.
  • Further research with broader anger scales is suggested for future screening batteries.
