PTSD: An imbalance between brain’s signaling systems

“Many people experience traumatic events in life, e.g. robbery, warfare, a serious accident or 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.

It has previously been shown that people with PTSD have altered brain anatomy and function. A new study by researchers from the Department of Psychology at Uppsala University and Clinical Neuroscience at Karolinska Institutet shows that people with PTSD have an imbalance between two neurochemical signalling systems of the brain, serotonin and substance P. Professors Mats Fredrikson and Tomas Furmark led the study using a so-called PET scanner to measure the relationship between these systems.

The study, which has been published in the scientific journal Molecular Psychiatry, shows that it is the imbalance between the two signalling systems which determines the severity of the symptoms suffered by the individual rather than the degree of change in a single system. ” More here.
