This commentary evaluates a recent single-case study by Cuttler et al that posits that a series of computerized tomographic (CT) scans ameliorated symptoms and signs of advanced Alzheimer’s dementia in an elderly female patient. The report proposes that CT scanning delivered low-dose ionizing radiation (LDIR) that activated adaptive mechanisms in the brain to induce the effects observed and reported. However, the report evidenced methodologic problems that threaten the validity and value of its approach, stated results, and conclusions. We provide discussion of these issues, with view and intent toward developing more precise investigations of the potential mechanisms and utility of LDIR in treating Alzheimer’s dementia and possibly other neurodegenerative disorders.
