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?
Hi, welcome to Chat Doctor forum.  At the age of 80, the natural changes in the body and brain also lead her towards such symptoms. They may be due to ischemia, due to atherosclerosis, anemia, lack of muscle tone of the body and arteries.  Less intake of food may lead to deficiency symptoms, and lack of energy.  I usually advise to my patients with such symptoms to take the fresh juice of the palatable vegetables without water, 2 times daily.  Wishing her a complete recovery. Thank you.
