A normal blood or urine test may still miss a thiamine problem that is localized to a specific part of the brain. This clip explains how researchers have reported region-specific or functional B1 abnormalities in Parkinson’s, Alzheimer’s, Huntington’s, and other neurodegenerative conditions, including problems with transporting thiamine into vulnerable brain tissue. It also looks at animal research using high-dose B1 with biotin, and why these findings have led to further human investigation.

This clip explores why thiamine responsiveness may not always look like a classic deficiency, and why normal blood or red-cell levels may not tell the full story about how B1 is functioning inside the nervous system.
