dad is 95. He may have had a T.I.A. five days ago. Symptons: sudden weakness in arms and legs so that he now needs assistance getting out of bed. Moreover, the walker is too hard to use. He is using a wheelchair and now needs support to get in and out. All of these are new; he was mobile with the walker just providing stability until last week. Lastly, following the possible T.I.A., he has been sleeping 18 to 20 hours a day. What, if anything, may be done to return the physical strength?
