What are the effects of PTSD on the brain?
It seems that the effects of PTSD on the brain indicate that there is a biological basis for the symptoms of this disorder. Scientists believe that experience with extreme psychological trauma can cause physical changes in the brain. However, it is possible that natural differences in the structure and brain function cause some people to be vulnerable to PTSD. The effects of PTSD on the brain are mostly in amygdale, which is part of the brain that helps control emotions. Hippcampus, prefrontal lobe and prefrontal bark may suffer damage due to traumatic experiences, and some experts believe that PTSD effects on the brain include changes in the way the brain uses certain neurotransmitters such as dopamine, serotonin and noradrenaline. Together with the prefrontal bark, Amygdala is usually responsible for helping emotions. In some PTSD suffering, amygdal actually increases, which could indicate an excess of emotional reactions in the brain. Changes in the way the brain uses neurotransmitters after experience traumaU, can cause reduced prefrontal bark function, which usually also helps to control emotions, especially fear. Experts believe that post -traumatic changes in prefrontal cortex function may occur due to elevated levels of neurotransmitter dopamine, which usually excludes the brain when a high level of alertness and caution is needed.
Many suffering PTSDs are experiencing a dull emotional condition after the onset of symptoms. Experts believe that this may be due to an increased level of neurotransmitters responsible for pain relief. The effects of the PTSD on the brain may also include a reduced ability to use a neurotransmitter serotonin, which is generally responsible for feelings of well -being. This could explain the readable feelings often accompany PTSD.
hippocampus, which is usually responsible for processing and storing memories, may also suffer from changes due to the effects of PTSD on the brain. Experts found that manyHo people with PTSD symptoms have less than normal hippocampus. One theory states that hippocampus could actually reduce during stressful events due to damage caused by the cortisol of stress hormone. Another theory states that someone who develops PTSD could have an unusually small hippocampus.
Ti with PTSD often experience difficulty in gathering their thoughts and expression. The effects of PTSD on the brain may include damage to prefrontal lobe, an area of the brain that usually regulates speech and self -expression. Increased levels of noradrenaline in the brain may explain the occurrence of intense physical slip reactions in PTSD patients, since this neurotransmitter usually causes a "fight or flight" response to stress situations.
