The Role of Dopamine in Major Depressive Disorder - Simply …
2024年4月22日 · A dopamine deficiency, among other neurotransmitters, can result in depression symptoms, such as apathy and hopelessness, by altering the way our brain's neural pathways are wired, how we navigate through our environment, and our relationship with ourselves.
Dopamine System Dysregulation in Major Depressive Disorders
Anhedonia is considered a core feature of major depressive disorder, and the dopamine system plays a pivotal role in the hedonic deficits described in this disorder. Dopaminergic activity is complex and under the regulation of multiple brain structures, including the ventral subiculum of the hippocampus and the basolateral amygdala.
The Role of Dopamine in the Pathophysiology of Depression
In some patients with depression, DA-related disturbances improve by treatment with antidepressants, presumably by acting on serotonergic or noradrenergic circuits, which then affect DA function.
