Exercise for Depression – A Gold Standard Therapy
Depression has become a common medical issue worldwide. Conventional treatments, generally, have not been effective in preventing recurrence of this condition. SSRIs can take months to provide a beneficial effect. Adverse side effects of antidepressant medications are a further concern, based on individual physical and mental health status. Additionally, in order to achieve remission, the most depressed patients require two or more different treatments.
A number of studies have shown exercise to be beneficial in the treatment of depression or depressive symptoms. Further, exercise has remarkable positive, and few negative effects on other disorders. From a physical standpoint, exercise engagement may improve hippocampal volume, pre-frontal cortex blood flow, and increase brain mediators such as brain-derived neurotrophic factor (which may be a key marker of depression).
With several other diseases, there is a concern regarding the effectiveness of different types of exercises: resistance or aerobic. However, in the context of treating depression and its symptoms, research shows that little difference exists between them, making the prescription far easier to physicians and the engagement almost limitless to patients.
Moreover, major depression is now well recognized as a risk factor for some of the most serious chronic diseases such as cardiovascular disease and diabetes, and similar in potency with traditional risk factors. Therefore, exercise prescription as a medical treatment would result not only in the improvement of depression, but also in preventing the occurrence of other diseases.
Vitally, data from several studies have shown exercise to be just as effective as medication in the treatment of depressive disorders. Furthermore, engaging in regular physical activity can reduce medication dependence. Even more importantly, other studies have demonstrated that exercise is more effective than medication in preventing relapse of the disease. It is also well established that additional benefits of exercise to individuals suffering from depression include reduced moodiness, better attitude, improved outlook, increased self-confidence, and enhanced mental well-being.
While the benefits of exercise as a depression treatment are undeniable, it may also have some barriers, for example intimidation, cost, or physical limitation. Therefore it is necessary to develop strategies for successful compliance by the patient, setting reasonable goals and preparing them for setbacks or obstacles.
Whether exercise is used as a first-line treatment or as a supplement to medication or psychotherapy, patients have virtually nothing to lose and much to gain from adopting an exercise approach in dealing with the symptoms of depression. Therefore, beyond the documented and aforementioned benefits of exercise on overall health, it is also time to more avidly begin considering exercise as a therapeutic strategy for patients suffering from depression.
