Transgenerational effects of PTSD or traumatic stress: do telomeres reach across the generations?
ثبت نشده
چکیده
Traumatic stress can alter allostatis and therefore mediate the development of psychological disorders. Recent evidence from molecular studies has shown that telomere length a measure of cellular aging is strongly influenced by a broad spectrum of stress. Telomere erosion might be accelerated by traumatic stress, and traumatic stress has shown to be associated with the risk of developing chronic diseases like cancer, cardiovascular diseases and immunologic conditions. Aim: The biological pathways between psychological stress and psychological disorders or physiological diseases are widely unknown. Some experimental studies in animal models and longitudinal studies in humans have investigated the transgenerational consequences of psychological stress on telomere length biology. Telomere length inheritance might provide an additional molecular mechanism for the germ line transmission of environmentally induced phenotypic change and might offer a new biological framework for the multifactorial path etiology underlying stress-related disorders. Procedure: Starting from the well-established allostatic load model, this article reviews theoretical and empirical work from animal models and humans in the field of telomere biology in association with traumatic stress, childhood trauma and post-traumatic stress disorders. Further it reviews recent approaches on telomere length inheritance, and combines these findings with transgenerational research of post-traumatic stress disorder biology. Conclusion: A better understanding of the transgenerational mechanisms underlying common diseases might ultimately help disease prevention of stress related disorders in subsequent generations.

Transgenerational Effects of PTSD or Traumatic Stress: Do Telomeres Reach Across the Generations?
In the last few decades, research has focused strongly on identifying biomarkers that are associated with stressand trauma-related disorders. This research provided the empirical evidence for several etiological models that explain the pathways from physiological symptoms to psychological disorders and vice versa. One of the best-known is McEwen and Stellar’s allostatic load (AL) model, which d...
متن کاملA review on the evidence of transgenerational transmission of posttraumatic stress disorder vulnerability.
OBJECTIVE To understand the risks of posttraumatic stress disorder (PTSD) development in the next generation of PTSD patients, we conducted a review on the biological, but not genetic, evidence of transgenerational transmission of PTSD vulnerability. METHODS Pertinent articles published from 1985 to September 2011 were searched using online academic search engines, including MEDLINE, EMBASE, ...

Although childhood is connected with high neuroplasticity changes, but because of the immaturity of the neural and cognitive systems, it is ready to grow developmental deviations and future susceptibility for neuropsychological disorders. Young children face cognitive, emotional, and linguistic limits that may lead them more vulnerable to post-traumatic stress disorder (PTSD). PTSD prevalence d...

Post traumatic stress disorder, a special disease that also accompanies with histological changes such as inflammation. In this paper we decided to review the relation between PTSD and inflammation. Stressful events causes immune system dysfunction by suppressing natural killer cells and altering levels of cytokines. Also in this condition, cytotoxic T lymphocytes results in under strained pro-...

I n this issue of Biological Psychiatry, Saavedra-Rodrı́guez and Feig (1) demonstrated that the experience of social stress during a period spanning from adolescence to adulthood induces longterm increases in anxiety-like behavior and social deficits in mice. However, the consequences of stress are revealed to extend far beyond this initial effect. Using a breeding design in which stressexposed ...
