[|Human|] Hi I have a 90 yr old friend who had congestive heart failure a year ago in November.  He continued working beginning in Feb of this year. He says his brain just isnt working. He is not remembering how to make the machines hes made for 30 years. He and his wife grow all the food they eat,  and all of it is organic. Im thinking it is the meds hes on. He is also wetting him self several times during the day and night.
[|AI|]  Hi, Welcome to Chat Doctor forum.  Your friend is 90 years old, and has the heart failure. There is every possibility of him to have an ischemia of brain, due to less blood supply to it.  I advise you to consult a neurologist for diagnosis and treatment. You may need to have an M.R.I. of brain for confirmation. He should have treatment as early as possible.  Cholesterol, atherosclerosis are to be examined for diagnosis and treated for.  Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to have an early recovery.  Wishing for a quick and complete recovery. Thank you.
