What is the relationship between PTSD and size of the hippocampus?

Question

Quizplus · Accepted Answer

Multiple studies have found a correlation between a smaller than average hippocampus and a higher risk of developing PTSD. This may be due to the role the hippocampus plays in regulating the stress response and memory processing, both of which are disrupted in individuals with PTSD. Therefore, choice C is correct. Choices A and B are incorrect because there is no evidence to suggest that PTSD directly causes a decrease in the number or size of neurons in the hippocampus. Choice D is also incorrect as there is no evidence to suggest that a larger than average hippocampus is associated with a higher risk of PTSD.
