Nutrient Deficiency-Related Depression and Mental Changes in Elderly Persons

Depression and dementia may be reversed if caused by nutritional deficiencies. The B-complex vitamins, vitamin C, zinc, and protein deficiencies especially are implicated in causing depression and affective disorders. However, as laboratory data are often unavailable, nutritional deficiencies must be identified clinically and treated by dietary changes or vitamin/mineral supplements or both given at appropriate and safe levels. This article will identify signs and symptoms of deficiency related to affective changes; will discuss risk factors for deficiency, including life style, disease, and medication; and will provide dietary sources of nutrients plus guidelines for recommended levels of supplementation.
