Interesting observations. Wonder if cerebral vasoconstriction could be related to functional vascular diseases such as Raynaud's syndrome, acrocyanosis and erythromelalgia. Much to learn.
OI syndromes in ME or LC: HR & RR are frequently normal despite significant drops in CBF. This often leads to the incorrect conclusion that there is nothing hemodynamically abnormal & thus no explanation or treatment needed. Review CBF assessment OI www.ahajournals.org/doi/10.1161/...

Interesting. If ketamine makes you ignore priors in a way similar to what is observed in schizophrenia, and FND is a problem of abnormally weighted priors and almost no one's seen FND in schizophrenia - has anyone tried ketamine for FND?
New paper in @brain1878.bsky.social: Healthy people under S-ketamine, an NMDAR antagonist, and people living with schizophrenia, a disorder associated with NMDAR hypofunction, spend more time in an external mode of perception - where noisy sensory signals override knowledge about the world.
