Witnessing fear in others can lead to change of flow of information in brain

A study has revealed that if a person gets to know something serious from his/her loved one or even strangers like a gunfire exchange, it can lead to change in information flow in the brain leading to post traumatic disorder.

Scientists in the study, published in Neuropsychopharmacology, found that fear in others may change how information flows in the brain.

Post-traumatic disorder is a kind of stress disorder which can develop in some people after experiencing a shocking, scary or dangerous event, says the National Institute of Mental Health.
