question: May Dad has recently been put in a nursing home with severe mental problems. Just this past October he was driving himself to the store and around town. In early November he was having trouble standing from a sore knee, then couldn t get out of bed and becoming very lethargic. He had a seizure and was admitted to the hospital, where they found his kidneys had shut down fro m dehydration. Now hes in the nursing home and doesn t communicate anymore? Years ago (2 or 3) he made fishing baits with lead and often melted lead in a little building. Could this be the cause of his problem?
