Vitamin b9 or folate deficiency can cause symptoms like dementia

I was diagnosed with this a few years ago and I have to take folic acid

As we get older it’s a good idea to have blood tests to see if we have any kind of anaemia or shortage of vitamin d or iron etc because it’s all too easy to label people as demented sometimes even fear can make someone appear to be demented as I saw with my husband when he had an accident
