Wasnt this study made in the UK where most people lack vitamin D, which is also associated with dementia and depression?

It's 20% incidence in general, highest in Asian (Indian etc) communities - not completely correlated with melanin.

A bit of a sidenote, but I find it fascinating how little vitamin deficiencies are accounted for in allopathic medical contexts.

Deficiencies seem like such a frequent occurrence but most patients end up needing to self-medicate.
