Suggest Remedy For Tremors In Hands And Excessive Sleeping In An Elderly Lady

My 96 year old mother has a catheter and is bedridden but has been able to read, do puzzles and generally be able to converse. Over the last 4 days she has started having tremors in her hands, unable to hold a glass or feed herself and sleeps almost all the time. She takes only Cymbalta and trazadone. She does not converse any more or even watch tv. Urinary tract infection has been suggested but the symptoms don t seem to match. Not sure what to do.
