Vitamin C Actions | Result of Reduced Vitamin C Availability |
---|---|
Cofactor in catecholamine synthesis | Reduced production of catecholamines |
Inhibits acetycholine release in rabbit caudate nucleus | Potential to disinhibit acetylcholine release and promote EPS |
Regulates postsynaptic actions of GABA and glutamate | Loss of this regulatory factor may tend to promote EPS |
Antioxidant | Loss of antioxidant activity may replicate the pathophysiology of Parkinson disease |
Abbreviations: EPS, extrapyramidal symptoms; GABA, gamma-aminobutyric acid.
