Question

Which of the following statements about post-traumatic stress disorder (PTSD) is FALSE?

		The enlarged hippocampus with PTSD may be responsible for difficulty in suppressing stress responses with PTSD and the memory problems of remembering key elements of the stressful event.
		The amygdala is more active in people with PTSD than in people without PTSD.
		This reduced size of prefrontal cortex neurons may prevent the prefrontal cortex from blocking the hypersensitivity of the amygdala to fear evoking stimuli.
		Fearful memories are hard to extinguish permanently.

Answer 1

Solution Option 1.

The statement "The enlarged hippocampus with PTSD may be responsible for difficulty in suppressing stress responses with PTSD and the memory problems of remembering key elements of the stressful event" is false. Because people with PSTD have smaller hippocampus

• The amygdala is abnormally active in people with PTSD than in people without PTSD. therefore option 2 is true
• The marked decrease in size of prefrontal cortex neurons prevent the prefrontal cortex and block the hypersensitivity of the amygdala to fear evoking stimuli.  Therefore option 3 is true
• People with PSTD have inability to inhibit or extinguish Fearful memories Therefore option 4 is true
