Filter by:Strokes often cause a loss of communication ability, referred to as aphasia, as well as cognitive difficulties. Each stroke survivor has a unique pattern of strengths and weaknesses in communication and cognition, and a unique course of recovery. The BUILD study aims to understand the brain basis of these individual differences in stroke outcome. Participants with stroke as well as controls matched in age, educational background, race, and sex are examined using a combination of standardized and in-house tests of language and cognition to provide a detailed profile of strengths and weaknesses. Each participant will have between three and six sessions, including an MRI to measure details of the structure, function, and connections in the brain. The data are analyzed to test how patterns in the stroke lesion explain the patterns of communication and cognitive difficulties, and how patterns in the uninjured parts of the brain explain resilience and recovery from the stroke. Ultimately, we hope that BUILD will guide us toward new targets for brain stimulation treatments or other biologically based treatments that improve language and cognitive abilities after stroke.
iReadMore will provide an app-based therapy for people with pure or central alexia. This study aims to test the clinical effectiveness of iReadMore for improving reading accuracy and speed in real world users of the therapy.
Many people with acquired brain injuries have deficits in reading decoding, reading comprehension, and written expression. Alexia is a phenomenon in which a person who previously could read has trouble doing so after having sustained a brain injury; likewise, agraphia is an acquired writing problem affecting one or more aspects of written communication. Alexia and agraphia sometimes co-occur with one another and/or with other language challenges, but they can also occur as isolated phenomena. Methods to treat alexia and agraphia often focus on single intervention techniques that address aspects of reading or writing in isolation-such as matching written and spoken letters or letter sounds, performing choral reading, tracing letters, etc. Existing research suggests that the effectiveness of these techniques is limited. However, when used in combination, such techniques may promote improved reading and written communication skills. As such, the purpose of this research is to determine the extent to which a multicomponent intervention program improves the reading and writing capabilities of people with acquired alexia and/or agraphia.
