STUDY: high serotonin linked to dementia; MEDIA: low serotonin linked to dementia
Once again, a level of misreporting that I am much more included to ascribe to malice than incompetence simply because most of the popular press outlets covering a specific scientific study get the study authors to proof-read the press article before publishing. So, for patently false press...- haidut

Adolescent stress causes mental illness, cognitive issues by lowering metabolism
It has long been known that pre-natal stress (e.g. stressed of the mother during pregnancy), as well as chronic stress after birth are associated with high risk of mental illness, criminal behavior, substance abuse, reduced cognitive function, chronic illness, and even early death. However, the...- haidut

High serotonin linked to poor aging trajectory (brain atrophy and depression)
This is one of the studies that Big Pharma will probably spend a lot of money on trying to get retracted. It directly demonstrates that elevated serotonin (5-HT) in the brain drives brain atrophy and depression. Both the rates and severity of these conditions increase with aging and the study...- haidut

Cognitive Benefits Of Caloric Restriction Are Due To Reduced Tryptophan/Serotonin/mTOR Signalling

Food as a tool for political change
Wanted to share another snippet of Ray's that I've listened to many times over: I feel like most people I've met fall into this authoritarian mindset where they accept the conventional wisdom / advice from 'experts' and don't question things enough.

Pregnenolone (P5) improves recovery from stroke
One of the few direct studies with P5 in-vivo, though that may be changing as I noticed the rate of articles on P5 has been rising over the last 5-6 years. This study used four (4) administrations of P5, at a HED of just 0.3mg/kg, 1, 6, 12, and 18 hours after the (ischemic) stroke was caused...- haidut

Exercise brain-boost may be due simply to increasing brain selenium levels

AlloP - Liquid Allopregnanolone For Lab/R&D
Just a quick announcement that we have replaced the 5α-DHP in our store with allopregnanolone. The main reason for switching over to allopregnanolone is that we always wanted to provide that steroid right from the start, however we could not find a lab willing to synthesize it. Thus, 5α-DHP... -
Air pollution impairs cognition, aspirin is protective

The biggest missing links to optimal brain function – part 1

Why Intermittent Fasting Actually Works (it’s Not What You Think)
