[|Human|] My father is 65 years old and is Diagnosed with brain shrinkage , age related atrophy changes ..Now he is unable to do his daily activities on his own, lost speech.Now taking ayurvedic medicine but nothing changes in his activities.How long does he live ?
[|AI|]  Hello, Unfortunately, there is no good answer to the question of his life expectancy since that is much more dependent upon his overall state of health and other comorbid conditions he may have such as hypertension, diabetes, and renal function (among others).  There are no known medications or treatments on the market to reverse the consequences of dementia. My advice is that he obtain a caregiver who can help with his activities of daily living.  This will help much more than medication in keeping him safe and improving his chances at a longer life in order to avoid falls and make sure he gets medications, HY Chat Doctor.  Hope I have answered your query. Let me know if I can assist you further. Take care
