When we think of depression, communication difficulties definitely come to mind, but who would have thought an overabundance of dysfunctional connections within the brain were to blame?
According to Andrew Leuchter and his team at UCLA:
Using functional MRI and electroencephalography (EEG), [they] measured the activity of depressed patients’ brains at rest. They found that the limbic and cortical areas, which together produce and process our emotions, sent a barrage of neural messages back and forth to one another—much more than in the brains of healthy patients. These signals, Leuchter says, can amplify depressed people’s negative thoughts and act like white noise, drowning out the other neural messages telling them to move on.
While other research seems to confirm these findings, scientists are not sure if the condition is a cause or effect of depression, but it could offer new, brighter avenues of treatment for patients who are desperately trying to escape wandering down the dark side of memory lane.
