Vitamin B6

I was diagnosed as having Asperger's Syndrome at the age of 40.  I have been prescribed vitamin B6 for over 44 years to help control an extremely rare condition known as 'PNPO Deficiency'.  Has anyone on the forum benefited from the use of vitamin B6 (with/without Magnesium and/or other B vitamins).  I have read that it is beneficial in some cases.
