Abstract

Depressive disorders and hypercholesterolemia are serious and common global problems. Many researchers have attempted to demonstrate association between concentration of the lipid fractions, depression as well as the rate of suicide, but the results are inconclusive. To overcome this lack of knowledge, we have summarized the studies concerning this relationship and published in recent years. All of articles included were published in peer reviewed journals and were identified through systematic query of PubMed with follow-up manual searches.

Concentrations of total cholesterol – TC, cholesterol – LDL-C, cholesterol - HDL-C other triglycerides and others atherogenic index and comorbidity with depressive disorders have been considered. While both positive and negative association between lipid fractions and depression have been shown in many studies, some data revealed no relationships between the two factors. In addition, we have also summarized the usage of statins and the occurrence of depressive disorders, and the results remain inconclusive.

In conclusion, our review did not reveal a clear relationship between lipid fractions and depression. Additional studies are needed as increased incidence of comorbidity between mood disorders and lipid disorders have been observed.
