ABSTRACT
Objective@#Loudness of dependence of the auditory evoked potential (LDAEP) is an electroencephalogram-based measure that represents amplitude changes of auditory evoked potentials in primary auditory cortex. Several narrative reviews argued that pre-treatment LDAEP values predict responses to selective serotonin reuptake inhibitors (SSRIs). This study aims to quantify the overall relationship between baseline LDAEP values and treatment response to SSRIs in patients with depression and generalized anxiety disorders, evidenced by clinical symptoms reductions, across multiple studies. @*Methods@#In our meta-analysis, seven articles with a total sample of 241 patients were included. @*Results@#Our results showed that stronger baseline LDAEP values predicted favorable response to SSRIs for depression and anxiety, with a moderate effect size. @*Conclusion@#The current results support the idea that LDAEP is a promising biomarker for SSRIs treatment prediction in patients with depression and generalized anxiety disorder.

ABSTRACT
OBJECTIVE: Previous studies indicate that emotion regulation problems in major depressive disorder (MDD) may be caused by difficulties in preferring useful emotions according to their goals. We investigated expected emotional usefulness and emotional preference in individuals with MDD (MDDs) and healthy controls (HCs). METHODS: Participants were given an interpersonal scenario with two different goals (confrontation and collaboration) and rated their willingness to participate in emotion-provoking activities and the expected usefulness of a particular emotion. RESULTS: MDDs were similar to HCs in expected emotional usefulness but showed different patterns of emotional preference. HCs preferred happiness to negative emotions across goals whereas MDDs did not show such pattern. In addition, HCs displayed goal-appropriate preferences whereas MDDs did not prefer certain emotions for specific goals. CONCLUSION: Although MDDs seemed to understand how useful an emotion can be, they did not show preference for goal-appropriate emotions. Interventions should address why MDDs have difficulty engaging in goal-appropriate emotions despite having full knowledge of the utility of emotions in achieving goals.

The aim of this article was to determine clinical significance of neurofeedback training of children with attention-deficit/hyperactivity disorder (ADHD). Many previous studies showed that the characteristic pattern of electroencephalogram (EEG) can be found in ADHD children. Neurofeedback training is developed based on this characteristic EEG pattern. Theta power and theta/beta power ratio have been known as useful indicators of neurofeedback training. However, in Korea, direct analysis of EEG change patterns before and after neurofeedback training is very rare. We reviewed the current findings of neurofeedback training of children with ADHD, and its clinical implications were discussed.
