The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

Troisi notes that attentional impulsivity is a demonstrated risk factor for suicide. Attentional impulsivity is related to mania and depression.

The study examined the relationship between cholesterol levels and attentional impulsivity in 301 patients with mood, anxiety, and personality disorders.

The study found:
(a) Lower cholesterol levels were associated with increased attentional impulsivity.
(b) Participants with cholesterol levels lower than 165mg/dL (4.2 mmol/L) were at a significantly increased risk of attentional impulsivity compared with the rest of the group.

The study shows that low cholesterol is associated with increased attentional impulsivity, and considering that attentional impulsivity is a demonstrated risk factor for suicide, the results of the study suggest that low cholesterol may be linked to an increased risk of suicide.

Low cholesterol levels associated with violence, antisocial behaviour and premature death
Both low cholesterol levels and declining cholesterol levels are associated with increased risk of death from suicide in men
