Regular exercise can reduce depressive symptoms to an extent that can mimic chronic antidepressant treatment (of course, one likely won’t hear about this from most doctors or from the pharmaceutical companies pushing their samples onto those doctors), and there are molecular mechanisms for this, apparently involving the Wnt signaling pathway. Abstract:
Regular exercise reduces depressive-like behavior activation. In this study, we look for exact roles of exercise on molecular and neuronal mechanisms for antidepressant action by studying the hippocampal neuroplasticity and proliferation. Increased hippocampal neurogenesis with exercise has potential significance for depression. Exercise promotes brain health in the molecular levels in the hippocampus and also affects behavior in a similar way to chronic antidepressant treatment. Wingless (Wnt) and frizzled signaling system plays an important role in cell proliferation, growth, and differentiation during development. Our results demonstrate complicated, differential effects of antidepressants on Wnt signaling system, and assume a role for selected signaling molecules in the neurogenic activity of antidepressant care. Our review suggests that exercise may preserve brain function by increasing neurogenesis through activating Wnt signaling pathway in the psychiatric disorders, such as depression.
Maybe exercise rather than popping pills should be the first line treatment for many mental, as well as more directly physical, disorders? First, ask you doctor about it - an informed doctor - and follow his or her advice. Everyone is different. Some people may require medication, others may only need exercise. Get the medical consultation you require to figure out which category you may be in, if you require such help.
