Summary
Gene expression and DNA methylation changes are linked to war-related post-traumatic stress disorder (PTSD). Identified genes may offer targets for personalized PTSD treatments.
Area of Science:
- Molecular Psychiatry
- Neuroscience
- Genetics
Background:
- Post-traumatic stress disorder (PTSD), especially war-related, presents complex etiological factors.
- Understanding the molecular underpinnings of PTSD is crucial for developing effective treatments.
Purpose of the Study:
- To systematically review gene expression and DNA methylation patterns in war-related PTSD.
- To identify key molecular pathways and potential therapeutic targets for PTSD.
Main Methods:
- Comprehensive literature search of PubMed, Scopus, and Web of Science (2000-2024).
- Inclusion of studies on adult military personnel with DSM-5 diagnosed PTSD, using blood, saliva, or brain tissue.
- Exclusion of animal studies, interventions, and pharmacological research; data extraction from 28 studies.
Main Results:
- Upregulation of immune-related genes (e.g., CCL4, NF-κB) and hypomethylation of inflammation-related genes observed.
- Downregulation of neurodevelopmental genes (e.g., BDNF, DSCAM) indicates disrupted synaptic plasticity.
- Identified pathways suggest potential biomarkers and targets for precision medicine in PTSD.
Conclusions:
- Gene expression alterations play a significant role in war-related PTSD.
- Identified genes represent potential candidates for personalized PTSD therapies.
- Further research is needed to validate findings and develop targeted interventions.

Introduction to Stress and Lifestyle
879
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

Psychological Responses to Stress
997
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

Stress and Mental Health
1.8K
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.

Psychoneuroimmunology: Cardiovascular Disease
758
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.

Generalized Anxiety Disorder
1.3K
Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

Post-traumatic Stress Disorder
981
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
