I recently have accidentally learned that my entire family is seriously deficient in vitamin D (even despite it's summer). A big surprise, and one that could have stayed undetected for many more years.
My almost 90 years old grandmother was having episodes of demency. She would see stuff that didn't exist, talk to people that weren't there, and not recognize her own relatives. After weeks of doctor visits, and we all being 100% sure she was having something serious like Alzheimers, turns out it was vitamin D deficiency.
Just sharing this here because I had no idea vitamin D deficiency could cause this.
Vitamin D deficiency actually really common, especially with dark skinned people living at higher latitudes. Most office people could do with a bit more UV.
