About the study
Loss of reading ability due to stroke, called alexia, likely affects over a million Americans at any given time and causes difficulty performing many daily life functions, such as paying bills, using email/text, reading for pleasure, and reading signs in the community. Understanding the brain and cognitive basis of alexia could improve diagnosis and treatment of this important problem. In this study, the investigators will perform a large-scale behavioral and brain imaging study of stroke survivors and typical older adults to improve our understanding of the brain and cognitive basis of reading in both of these groups.
Participants will complete a battery of tests of reading, speech, language, and thinking abilities. In addition, some participants will complete an MRI. Sessions will be completed across approximately 2-6 weeks, but may be extended depending on participants' schedules and availability. Some participants will be invited to repeat these procedures once or twice in approximately 3-12 months to monitor for changes in reading abilities and MRI measurements over time.
