Low lipids may flag higher depression/suicide risk warranting vigilance; hypothesis-generating and requires prospective causal studies before practice change.
A large number of studies have been performed to establish a correlation between serum cholesterol and depression. Majority of the studies have suggested that depression and suicide are associated with low levels of serum total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglycerides. However, few researchers have also denied the association between serum cholesterol and depression or suicide. We carried out an extensive literature search for the studies performed on serum cholesterol and depression, and found that a relationship definitely exists between the two.
