Antidepressant medicines, combined with cognitive-behavioral therapy (CBT) may produce optimal therapeutic effect, according to Yina Ma, Ph.D., a research scientist at Johns Hopkins’ Lieber Institute for Brain Development. In Molecular Psychiatry she reports: “Antidepressants act to normalize abnormal neural responses in depressed patients by increasing brain activity to positive stimuli and decreasing activity to negative stimuli in the emotional network and [by] increasing engagement of the regulatory mechanisms in” the key region in mediating the regulation of both positive and negative emotions, she explained.
Although both antidepressant and cognitive-behavioral treatments:
“Affect emotion-related and prefrontal circuits to a similar end state of normalized emotional network and prefrontal activity, the mechanisms by which each treatment acts may differ. Although it has been proposed that CBT targets prefrontal function as it focuses on increasing inhibitory executive control, the current findings raise the possibility that antidepressants may act more directly on the emotional network. Taken together, a combination of an early antidepressant medication and follow-up CBT may therefore result in a better therapeutic effect, a possibility that needs to be directly addressed in future research.”
