The brain is the most powerful and vital tool we own. Nurtured and maintained, with the right genetic potential, it can reach human genius.
What mental and physical consequences are there if we traumatize it?
One of the most common problems is Post Tramatic Stress Disorder, or PTSD. It occurs after experiencing traumatic events, such as war or terrorism. Some of its manifestations are avoidance, flashbacks of the event, difficulty concentrating, insomnia… and survivor guilt.
Some studies suggest that continued exposure to a stressor may damage the hippocampus, the part of the brain responsible for memory. Under pressure, the body releases cortisol, a hormone that helps with adaptation. Animal studies show that high cortisol levels have apoptotic effect, causing programmed cell death in the hippocampus.
As shown in the video below, this disorder is encountered among war veterans, who were confronted with horror and constant threat of instant death. PTSD is much more prevalent than we think… “And the wars continue”.
Someday, will we be able to “fix” the brain ? Can we possibly modify our reaction to strong emotions like fear, guilt, stress ?
