    Progesterone receptors and serotonin levels in colon epithelial cells from females with slow transit constipation (P4 lowers SERT)

    Abstract link to study Background: Females with slow transit constipation (STC) exhibit progesterone receptor (P4R) overexpression in colon muscle that impair their contractility. These studies examined whether these patients have an overexpression of P4R in epithelial cells and...

    Serotonin (and SSRI drugs) can cause anxiety and PTSD

    Yet another great study exposing just how much of a "happy hormone" serotonin really is. As usual, the popular press article does everything possible to avoid pointing the finger at serotonin and even engages in misdirection. For example, it says that SERT is the main target of drugs like...

    PUFA And Serotonin Promote Each Other, And Likely Cause Mental Illness

    I neat new study that draws a direct parallel between PUFA-driven inflammation, serotonin and depression. As the study demonstrated, high levels of the PUFA arachidonic acid (AA) are highly correlated with lower density (expression) of the serotonin transported (SERT, 5-HTT), and the...

    Serotonin Excess, Not Dopamine Deficiency, May Be The Cause Of Parkinson

    One of the most paradigm-challenging studies I have seen this year and, unsurprisingly, mainstream media is pulling all sorts of tricks to avoid naming the culprit directly. Even the press release and the study abstract are worded in a convoluted way, talking about a "serotonin dysfunction"...

    Elevated Serotonin Increases Criminal Activity

    The study looked at correlations between ambient temperature and criminal activity and found that higher temperatures correlate with reduced SERT density and as such elevated serotonin. The SERT protein is the one that deactivates serotonin and it is a sodium dependent protein. Serotonin...

    Serotonin/endotoxin/PUFA As Primary Causes Of Depression And Diabetes; Can Be Easily Blocked

    This is one of the unique studies that breaks away from the mainstream dogma that serotonin is the "happy hormone" and increasing it with drugs like SSRI can lead to nothing but goodness. The study not only directly states that past/current SSRI use is a risk for developing diabetes but show how...

    Tremor In Parkinson Disease (PD) Is Due To High Serotonin

    The non-motor signs/symptoms of PD (tremor, drooling, slurred speech, etc) have long been thought to be directly due to dopamine deficiency due to the death of the nigrostriatal dopamine neurons. The common treatment for those signs/symptoms and the motor symptoms as well is usually a dopamine...

    Colon Aging / Cancer? Due To Low NAD / High Serotonin; Niacinamide Reverses Both

    Peat has said many times that the impaired bowel regularity that occurs in aging, hypothyroidism and various pathologies is due to high NO and serotonin. He also said that while serotonin inhibits motility in the colon it increases it in the small intestine. Most doctors do not agree with that...

    Higher Serotonin Availability May Be The Cause Of Cognitive Impairment / Dementia

    Some of you may have seen this study in the news lately. However, it is being presented as the exact opposite as what my title says. The media titles all over the Internet proclaim that "John Hopkins study shows low serotonin causes dementia". However, if you look at the actual study you will...

    Poverty Causes Depression By Increasing Serotonin Activity

    The conditions of learned helplessness and PTSD have many features in common and both of them have been linked to dysfunction of the monoaminergic system. There has been a lot of research over the last decade tying adverse life conditions in childhood to mood and memory problems as an adult...
