Summary
This review suggests impaired parasympathetic activity during sleep in posttraumatic stress disorder (PTSD), not increased sympathetic activity. This finding may explain cardiovascular risks and other health issues in PTSD patients.
Area of Science:
- Neuroscience
- Sleep Medicine
- Psychiatry
Background:
- Posttraumatic stress disorder (PTSD) is linked to increased cardiovascular disease.
- Autonomic nervous system (ANS) function during sleep in PTSD is not well understood.
- Comparative ethology of sleep under threat provides a framework for this review.
Purpose of the Study:
- To review existing data on ANS status during sleep in PTSD.
- To explore the implications of ANS function for cardiovascular health in PTSD.
- To identify potential medical comorbidities associated with PTSD.
Main Methods:
- Systematic review of current literature on ANS in PTSD during sleep.
- Analysis of data within the framework of sleep ethology under threat.
- Consideration of measurement challenges and future research directions.
Main Results:
- Limited evidence suggests impaired parasympathetic drive during sleep in PTSD.
- Current data does not support increased sympathetic drive in the periphery during sleep in PTSD.
- Findings highlight a potential link between ANS dysfunction and cardiovascular risks in PTSD.
Conclusions:
- Impaired parasympathetic activity during sleep may be a key feature of PTSD.
- Understanding ANS alterations can inform cardiovascular disease prevention in PTSD.
- Further research is needed to clarify ANS mechanisms and identify comorbidities in PTSD.

Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

01:15REM Sleep Behavior Disorder
331
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.

01:11Understanding Sleep
453
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).

01:18Nightmares and Night Terrors
146
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.

01:24Substance Use Disorders Affecting Sleep
207
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.
