Neurochemical Imbalance Linked with Susceptibility to PTSD [PsychCentral.com]

 

New research finds that an imbalance between two neurochemical systems in the brain is linked to posttraumatic stress disorder with the greater the imbalance, the more serious the symptoms.

Researchers from Uppsala University and the medical university Karolinska Institutet in Stockholm, Sweden, found that people with posttraumatic stress disorder have an imbalance between two neurochemical systems in the brain, serotonin, and substance P.

Experiencing a traumatic event is not uncommon be it a robbery, warfare, a serious car accident, or a sexual assault. Approximately 10 percent of people subjected to trauma suffer long-lasting symptoms in the form of disturbing flashbacks, insomnia, hyperarousal, and anxiety.

If these problems lead to impairment, the person is said to suffer from posttraumatic stress disorder, PTSD.

Prior research has shown that people with PTSD have altered brain anatomy and function. In the new study, researchers discovered people with PTSD have an imbalance between two neurochemical signalling systems of the brain, serotonin, and substance P.

I agree with you, Tina. This article and the research doesn't look at epigenetics, and it should. We post articles like this to show the state of the research, as a way of educating and encourage members to contact the researchers to find out if they know about ACEs (writ large....epidemiology, neurobiology of toxic stress, epigenetics, biomedical consequences of toxic stress, resilience research), or at least to know that we have a big job to do in educating various sectors about ACEs so that research is done differently, and that journalists ask better questions.    

You providing this comment is a first step. Thank you!

This is another terrible article that doesn't look at epigenetics, again could make people think they have faulty brains with a "chemical imbalance" and lead the drug company charge for the next Prozac and big money for profits  while telling patients they have feeble brains whose trauma (regardless of whether it was attachment trauma or a single incident adult onset car accident are the same and should be treated similarily). This simply isn't true. The care will again be directed to the quick fix pill - or chronic long term medication --the afflicted patient with the feeble brain needs to pop into his/her mouth for the rest of life at the expense of doing real research on meditation, yoga, neurofeedback etc. Not trying to be critical,  but I would assume this site is capable of picking better articles. These kinds of articles become drug profit propaganda. They pathologize hurt people. They lead to the massive over medication of foster care and poor traumatized children!  This over medication represents the abuse of poor and disadvantaged children and corporate welfare for big pharma! Thanks Tina
