Emotions out of control due to cholesterol? It’s possible that the levels are influencing mood and behavior.


CHOLESTEROL is a fatty substance found in some foods and also produced by your body. Little is known about cholesterol and how it can impact one’s overall mood.

The link between high cholesterol and heart disease is well established with countless trials showing that lowering cholesterol both through lifestyle changes and pharmacologic means was highly beneficial in reducing serious health outcomes. However, some scientists wondered if there was a hidden price to be had for better heart health.

Several studies have found that low serum lipid levels are associated with persistently low platelet serotonin levels in depressed patients.

Researchers have hypothesised that low cholesterol levels indirectly lead to reduced brain serotonin because of the requirement of adequate cholesterol in nerve cell membranes to maintain the functional integrity of serotonin receptors.

These observations are consistent with a high rate of severe depression in individuals afflicted with a rare genetic syndrome which causes an enzyme deficiency resulting in abnormal low serum cholesterol.

A study published in the journal Biochemistry looked at direct links between abnormal low brain cholesterol levels and impaired serotonin function.

Researchers looked at the correlation between increased rates of suicide and violent behaviour and low cholesterol levels.

Researchers reported a significant reduction in the level of serotonin binding and G-protein coupling to serotonin 1A receptors resulting from chronic cholesterol depletion following treatment with mevastatin, which is one of the more lipophilic statins.

Another study published in the National Library of Health, cholesterol and mental health was further investigated.

The study noted: “A quarter of a century ago, a meta-analysis of six primary prevention randomized controlled trials (RCTs) suggested that lowering serum cholesterol levels was associated with an increased risk of mortality related to accidents, suicide, or violence; a decade later, a meta-analysis of 19 RCTs showed that deaths due to these causes were not increased in patients treated with statins for either primary prevention or secondary prevention.

“In fact, meta-analysis of epidemiological as well as RCT data suggests that there is a lower risk of depression in statin users, and that statin augmentation of selective serotonin reuptake inhibitors has an antidepressant effect.

“Finally, and most important of all, it is important to reduce serum cholesterol in patients with major mental illness if only because such patients are at an increased risk of metabolic syndrome; statin treatment in such patients could,. “Brinkwire Summary News”.
