<bot>: Hi, Thank you for posting your query. I have gone through the list of symptoms that you provided. There are too many of them, and you require a detailed and careful examination to come to a conclusion. A few diagnostic possibilities I would consider are:1. Vitamin B12 or D deficiency,2. Hypothyroidism,3. Low blood sugar or sodium4. Less blood flow to the brain, etc. I hope it helps. Please get back if you require any additional information. Best wishes, Chat Doctor. Ly/
