How could a neurologist's understanding of the brain help explain why some individuals may develop PTSD following traumatic events while others do not? Neurologists could claim that traumatic experiences don't actually cause changes in the brain leading to PTSD. Neurologists might investigate variations in brain structures or neural processes to understand differences in individual resilience or vulnerability to PTSD post trauma. Neurology only deals with organic brain diseases, so it wouldn't provide insights into psychological conditions like PTSD. A neurologist might argue that everyone’s brain reacts identically to traumatic experiences, thus dismissing the variations seen in PTSD development.
