Loudness dependence of auditory evoked potential (LDAEP) can reflect adult attention deficit and hyperactivity disorder (ADHD) symptoms in major depressive disorder (MDD), a new study suggests. 60 participants (40 subjects with MDD and 20 healthy controls) aged >18 years who had LDAEPs performed during electroencephalograms were included. ADHD symptoms, depressive symptoms, and anxiety symptoms were evaluated. Researchers found:
- MDD subjects with ADHD symptoms shoed significantly lower LDAEP levels compare to those without ADHD symptoms and healthy controls.
- LDAEP differences between MDD subjects without ADHD symptoms and healthy controls was not statistically significant.
- Significant correlations of psychological scales of depression, ADHD symptoms, and LDAEPs were found.
