[dean and keshavan 2017] there are converging lines of evidence that mdd is a matrix of pathophysiological mechanisms that encompass altered cellular neurochemistry and neurocircuitry.Regulation of emotions takes place in three.The rate of adult neurogenesis fluctuates in response to several environmental factors.The neurotrophic theory holds that the extent of atrophy of neurons and decreased volume of limbic brain regions, comprising of prefrontal cortex and hippocampus, correlates to the occurrence of depression.The circadian rhythms theory of depression developed out of successful treatments of depression.

According to this hypothesis, when someone takes antidepressants, the drugs do raise levels of monoamines like serotonin, but they also.Impaired adult hippocampal neurogenesis and depression may be reciprocally causative.Ablation of neurogenesis in animal models impairs cognitive functions relevant to depression, but only a minority of studies find that ablation causes depression or anxiety.Chronic stress, which can lead to neuronal apoptosis and.Neurogenic theory what is the monoamine hypothesis of depression?

The affective and rational system—the basis.A well synchronized circadian rhythm is critical for maintaining optimal health.adverse changes and alterations in the circadian rhythm have been associated various neurological disorders and mood disorders including depression.Put simply, neurotransmitters are chemical messengers in the brain.This has led researchers to conclude that abnormal sleeping patterns may contribute to depression.Department of neuroscience, the chicago medical school north chicago, il usa.
