  1. 1) What role does cholesterol play in the brain? I've read
    it is the most prevalent molecule present in the brain.

    2) Does anyone know the median value of serum cholesterol
    for the general population who are not taking cholesterol-
    reducing medications?

    Thanks for any info.

    Cholesterol is used in the growing brain for myelination.
    Once the brain is grown and fully myelinated, there is
    probably very little need for additional cholesterol.

    Depends on the population. For growing children, it is
    typically between 100-150 mg/dL.

    Cholesterol, essential fatty acids, and suicide by Brunner
    J, Parhofer KG, Schwandt P, Bronisch T. Max Planck

    Germany. [email hidden]. de Pharmacopsychiatry 2002
    Jan;35(1):1-5

    ABSTRACT Epidemiological and clinical studies have described
    an association between lower serum cholesterol
    concentrations and increased suicide risk that is not
    entirely attributable to depression-related malnutrition and
    weight loss. Recent epidemiological studies with greater
    samples and longer follow-up periods, however, have even
    shown a positive correlation between cholesterol
    concentrations and suicide risk after controlling for
    potential confounding variables. A meta-analysis of earlier
    intervention trials suggested that cholesterol lowering
    could cause or worsen depressive symptoms and increase the
    risk of suicide. Large trials of statins (simvastatin,
    lovastatin, and pravastatin) did not show an increase of
    suicide mortality. The aim of this selective review is to
    critically discuss the current evidence for a potential link
    between cholesterol, essential fatty acids, depression,
    suicide, impulsivity, and aggression. Preclinical data
    support the hypothesis that cholesterol reduction may
    contribute to the serotonergic abnormalities that have been
    postulated in suicidal subjects. Recently, it was
    hypothesised that a decreased consumption of polyunsaturated
    fatty acids, especially omega-3 fatty acids, may be a risk
    factor for depression and suicide. Currently, we do not have
    sufficient evidence that cholesterol-lowering therapies
    increase the risk of depression and suicide. Increasing the
    dietary intake of omega-3 fatty acids may increase central
    serotonergic activity and reduce impulsive and aggressive
    behaviours.

    In other words, higher cholesterol --> more suicides.

    Sciences Center Emory study finds mental health and heart
    disease tightly linked Attaining and sustaining good mental
    health is just as vital as other factors, such as exercise
    and diet, in the prevention of cardiovascular disease,
    especially for women over the age of 45, according to a
    study by Emory University sociologist Corey Keyes published
    this month in the journal Aging and Mental Health. Using
    national survey data, Keyes' study examined the prevalence
    of mental health issues among people with cardiovascular
    disease, the leading cause of death in the United States. In
    investigating linkages between the two, Keyes used a measure
    of mental health as a "complete state" that looked beyond
    episodes of mental illness to also incorporate the
    subjective well-being of people, and how well they are
    functioning and flourishing in life. The study found that
    cardiovascular disease was lowest in adults who were the
    most mentally healthy, and higher among adults with major
    depressive episodes, minor depression and moderate mental
    health. The relationship between cardiovascular disease and
    mental health was the same for age

    ages of 45 and 74, where mental health issues under his
    "complete state" measure were much more prevalent. Previous
    research has found major depression and stress to be
    contributing factors for, and a consequence of,
    cardiovascular disease, Keyes says. Although good mental
    health traditionally has meant the absence of mental
    illnesses like depression, health care professionals, in
    treating patients with cardiovascular disease, "should view
    and evaluate mental health as more than merely the absence
    of psychopathology, and look at the full picture of how
    their patients are coping and functioning in life," he says
    Overall, only 17 percent fit the criteria for full mental
    health in the study. As a result, estimates of
    cardiovascular disease risk among adults with lower levels
    of positive mental health are likely to be inaccurate and
    possibly underestimated, he says. "We seriously
    underestimate the connection between mental health and
    cardiovascular disease, especially for post-menopausal
    women. We are not doing as well in treating mental health on
    par with other risk factors," says Keyes, an associate
    professor of sociology who conducted the study in
    conjunction with Emory's Rollins School of Public Health.
    Keyes' study used data from a representative sample of
    American adults between the ages of 25 and 74 collected in
    1995 from the MacArthur Foundation's "Midlife in the United
    States" survey. About 12 percent of adults reported some
    form of cardiovascular diseases. Independent of mental
    health status, risk for any cardiovascular disease increased
    with age and as education decreased, and the risk was higher
    among males, married adults and unemployed adults. Keyes is
    lead editor of "Flourishing: Positive Psychology and the
    Life Well-Lived," published in 2002 by the American
    Psychological Association, and is co-editor of "Well-Being:
    Positive Development Throughout the Life Course," published
    in 2003 by Lawrence Erlbaum Associates Inc.

    demands additional amounts that must be provided by
    glia. Thus, the availability of cholesterol appears to
    limit synapse development. This may explain the delayed

    "Cholesterol, which is an essential component of the
    plasma membrane, has a bad reputation, because high
    cholesterol levels in the blood raise the risk for
    atherosclerosis and consequently heart attack and
    stroke. The identification of cholesterol as
    synaptogenic factor shows a surprisingly beneficial side
    of this infamous molecule. The new results suggest that
    the availability of cholesterol in the brain limits the
    extent of synaptogenesis and that a defective
    cholesterol metabolism in the brain impairs its
    development and function.

    Neurons appear to produce enough cholesterol to survive
    and to grow, but require external cholesterol to form a
    sufficient number of synaptic contacts. Since cells in
    the brain cannot access the cholesterol supply in the
    blood, they need to synthesize cholesterol by
    themselves. According to the new results, glial cells
    produce surplus cholesterol and deliver it to neurons
    via lipoproteins. This dependence indicates a new role
    for glial cells as cholesterol providers and could
    explain why synaptogenesis in the CNS occurs after the
    differentiation of macroglial cells."

    Cholesterol is used in the growing brain for myelination.
    Once the brain is grown and fully myelinated, there is
    probably very little need for additional cholesterol.


    Brain needs cholesterol for proper functioning, see
