Trial Parameters
Brief Summary
Patients with stroke frequently suffer from aphasia, a disorder of expressive and/or receptive language, that can lead to serious health consequences, including social isolation, depression, reduced quality of life, and increased caregiver burden. Aphasia recovery varies greatly between individuals, and likely relies upon the capacity for neuroplasticity, both at a systems level of reorganized brain networks and a molecular level of neuronal repair and plasticity. The proposed work will evaluate genetic and neural network biological markers of neuroplasticity associated with variability in aphasia, with a future goal to improve prognostics and identify therapeutic targets to reduce the long-term burdens of aphasia.
