My mother had RA and prescribed prednisone. She developed Feltys. She was hospitalized with pneumonia twice, her spleen was swollen at times. Her immune system was not functional at all. She developed leukopenia. Then her RA went into remission. Then she had an episode (we thought she had a stroke, her doctor said she did not), she was hospitalized with pneumonia again, put into a coma for 2 weeks. When she came out of her coma, she had to learn how to walk and talk again. She eventually went back to her life, but she was different. She started acting very odd and very forgetful. She was diagnosed with Alzheimer’s. When this began, she was 61. When she died, she was 77. Could the prednisone have caused her Alzheimers?
