Low B1 levels cause oxidative stress and drive neurodegeneration.

Low B1 levels cause oxidative stress and drive neurodegeneration.
main example is Alzheimer's disease.
Lack of thiamine-dependent enzymes in brain such as
-Pyruvate Dehydrogenase (PDH)
-a Ketoglutarate Dehydrogenase Complex (a-KGDH)
-Transketolase (TK)
are directly linked to AD, seen by reduced glucose metabolism.

B1 acts as an antioxidant by being a strong protector against oxidative stress.

The ability to utilize glucose is low in AD patients, this explains how B1 can treat it and lack of it can cause it.

B1 + Acetazolamide can treat parkinson
