Mouse Study: How Fear Turns Into Chronic Anxiety
anxiety in some individuals.“Until now, psychiatrists had little information about what goes on in the brain after a fearful experience, and why some people don’t easily recover and remain anxious, for even as long as the rest of their lives,” says team leader Elaine L. Bearer, MD, PhD, from the University of New Mexico (UNM).The goal of the study was to shed light on the brain’s response to fear and why, in some cases, it can lead to prolonged anxiety states like post-traumatic stress syndrome (PTSD).While studying a mouse model, the researchers found that brain activity in anxiety is not the same as in an acute fear response.
