Background: The older population makes up the largest group of people struck by mental depression. Meanwhile it is also the most rapidly increasing population group suffering from depression. There is a lack of research in this field and there are indications that older people do not respond to treatment in the same way as the younger population. The aim of this literature review is to examine methods of treatment for depression in the elderly population.Method: A systematic literature review with thematic content analysis of quantitative data.Results: Fifteen articles were included. The analysis resulted in four themes: Physical activity, Therapy, Social interaction, Medical treatment. Conclusion: There are indications of treatments with good effect, but it is difficult to identify possible clinical implications due to heterogeneity within the study population. More studies in the field focusing on subgroups are needed.
