So finally I am going back to India for my treatment but yesterday a very weird thing happened. I used the word "vicinity" without quite being sure about its meaning. I mean I have been using vicinity since childhood and know what it means but for a split second my mind went blank and it was scary...I wasn't sure if vicinity actually means surroundings :(. Is it common in B12 deficiency to forget the meaning of elementary words? Also lately I am getting spellings of really common words all jumbled up. If this is actually due to b12 deficiency then its scary. Looking forward to some similar experiences or advice on how to counter this.
