When Cathy Fields was in her late 50s, she noticed she was having trouble following conversations with friends...Fields was worried she had suffered a stroke or was showing signs of early dementia. Instead she found out she had attention deficit hyperactivity disorder or ADHD...Her doctor ruled out any physical problems and suggested she see a psychiatrist. She went to Dr. David Goodman at Johns Hopkins School of Medicine, who by chance specializes in ADHD.
