New case study offers causal evidence linking the right amygdala to PTSD
A man with epilepsy and severe PTSD had part of his right amygdala inactivated during awake surgery. Within 20 minutes, he stopped reading ambiguous faces as fearful. Two months later, his PTSD score had fallen below the diagnostic threshold.
In a groundbreaking clinical case study, a man with drug-resistant epilepsy and severe post-traumatic stress disorder (PTSD) experienced a significant reduction in his tendency to perceive ambiguous faces as fearful after the selective inactivation of his right amygdala. Published in Nature Communications, this study offers compelling causal evidence linking right amygdala activity to threat-focused biases and PTSD symptoms.
