Systematic review of depression
Systematic review of depression indicated that there are different levels to the disorder: genetic, neural, and hormonal. Successful public health practitioners should consider these levels even as they explore brain function in individuals affected by depressive disorder. There exists extensive correlation between brain and neurovascular functions. Some pharmacological principles used in treatment of depression are consistent with the research findings whereas others are not. Most cases of depression are treated using antidepressants as the first line of response. Randomized control trials examined in the course of research revealed that antidepressants have unsatisfactory efficacy. They are associated with likelihood of remission and undesired side effects such as dysfunction and weight gain.
Most public health practitioners use approaches that are aligned to current and progressive research findings. Alternative therapies used in treating depressive disorders include individual counseling, group therapy, and exercise. Such methods are encouraged because findings discourage the entire dependence on medicine. Therapy and counseling are useful services, enabling the cultivation of psychosocial resilience required in handling depression. Even so, there is a gap that remains to be applied with regard to Late Life Depression (LLD). Focus lies heavily towards assisting those who have already been diagnosed with depression. However, since chances of developing LLD increase as people age, studies should be directed towards identifying genetic markers and biological indicators that point help in identification of those at risk. The public should also be well informed concerning behaviors indicative of chances of an individual developing LLD, since it has an associated psychosocial aspect. Community health workers may be involved in such a strategy by educating the public.
