Some survivors of disastrous events have post-traumatic stress disorder (PTSD). Symptoms include nightmares about the experience and suddenly feeling as if the event is recurring. Brain-imaging studies of people with PTSD showed that their hippocampus was shrunken and their amygdala unusually active. Given these changes, what other brain functions might be disrupted in PTSD?
To explain: The other functions that might be disrupted in post-traumatic stress disorder (PTSD).
Concept introduction: Post-Traumatic Stress Disorder (PTSD) affects the hippocampus and the amygdala. Both the components belong to the limbic system. It works with the cerebral cortex and controls the emotions and contributes to memory.
Post-Traumatic Stress Disorder (PTSD) develops in some people who have experienced or witnessed disastrous, shocking or dangerous events. It is a mental health condition in which a person feels that the traumatic events are recurring. It is given in the question that the brain-imaging of the people with PTSD has shrunken hippocampus and unusually active amygdala. Hippocampus and amygdala are the components of the limbic system that function in the expression of emotions...
