In humans, it is widely accepted that brain-derived neurotrophic factor (BDNF) participates in the psychophysiology of psychiatric disorders. Yet the relationship between BDNF levels and psychopathological traits in the general population has not been examined. To test whether BDNF blood levels are associated with the modulation of psychopathological traits in healthy subjects, we assessed the correlation between BDNF serum and plasma levels measured at 9am and psychometric parameters using the symptom checklist 90 revised (SCL-90R) and temperament and character inventory (TCI)...
