Detail Info
Sample Diagnosis |
DSM-IV |
Related Diagnostic Tools |
Acute Stress Disorder Scale (ASDS), Clinician-Administered PTSD Scale (CAPS), Mini International Neuropsychiatric Interview (MINI) |
Sample Status |
42.3% with ASD, 18.9% with current MDD, 55.3% with any MINI disorders |
Controls Exposed |
NA |
Replication Size |
None |
Result Summary |
Neither BDNF Val66Met genotype nor plasma BDNF was significantly associated with the presence or severity of ASD or PTSD. |
Potential Biomarker |
Plasma BDNF may, therefore, be a marker of trauma load. |
