The 73-year-old widow came to see Dr. David Goodman, an assistant professor in the psychiatry and behavioral sciences department at Johns Hopkins School of Medicine, after her daughter had urged her to “see somebody” for her increasing forgetfulness. She was often losing her pocketbook and keys and had trouble following conversations, and 15 minutes later couldn’t remember much of what was said.
But he did not think she had early Alzheimer’s disease. The woman’s daughter and granddaughter had both been given a diagnosis of A.D.H.D. a few years earlier, and Dr. Goodman, who is also the director of a private adult A.D.H.D. clinical and research center outside of Baltimore, asked about her school days as a teenager.
