Previous observational and interventional studies have shown that regular physical exercise may be associated with reduced symptoms of depressions. The degree to which exercise training may reduce depression symptoms in elderly patient with extreme cases of depression disorders hasn’t been evaluated though. However, it has been found that patients who receive antidepressant would respond faster at the initial stages when compared to those who could take both antidepressants and training. Cases of less severe depression, respond more rapidly through exercise than those with more severe depression symptom. It has been noted that exercise would bring the same results as depressants if they were to be used to manage depression.
