 Neuroticism is a personality trait described as an enduring tendency to experience negative emotional states and to respond poorly to environmental stress. It has been shown that high neuroticism can predispose, amongst other factors, to the development of depressive episodes. Recent studies suggest that subjects with high neuroticism have a different response to stimuli with an emotional content, showing both decreased processing of positive or increased processing of negative emotionally salient cues. These differences in cognitive processing of emotional stimuli are believed to underpin the psychological characteristics that link high neuroticism with a higher risk for depression.
