question: My mother is 80 years old and last 2 months she had three episodes where she does not wake up from sleep. After 10-15 minutes of splashing water she wakes up . Today it took her about 45 minutes to come to senses. When she woke up her Bp was 150/128. However by the time we took her to hospital it was 150/90. She is diabetic for 25 years and recently was diagnosed with low b12  274 and high homocysteine 20.1. She is also showing signs of dimentia and hallucination for which she is being given b12 shots. Can you please help?
