简要总结
Memory deficits are common after traumatic brain injuries (TBI) and are characteristic of various forms of dementia, such as Alzheimer's disease and its common precursor mild cognitive impairment (MCI). This project intends to assess the efficacy of cognitive rehabilitation in these patient populations. We will also use neuroimaging (functional magnetic resonance imaging - fMRI) to assess changes in brain activity that occur following cognitive rehabilitation.
