Just a few days ago I had suggested these ideas to someone who has a mother who was in the hospital for possible kidney failure and who had pretty much stopped talking. I thought making up a few cards with large words such as NO, YES, LESS, SOME, MORE, ITCHY, DRY, THIRSTY, HUNGRY, COLD, HOT, WARM, COOL. Do all the talking asking questions slowly and clearly, & have cards available so they can answer by pointing to them. Have pictures of things and people important in their life. Label them with large letters - HOME,DOG, PIANO,kitchen, Workbench, Garden, spouse's name, a daughter or son's name, etc. If no answer at first, just keep doing it until the person catches onto what is in front of them and what you are doing. It takes patience. Go Slowly, so they make the connections. It takes time to rebuild language and visual/audio connections & coordination, just as it takes time to rebuild the physical pathways for walking.
