Study Overview
Brief Summary
Combined analysis of functional and structural language network changes may be a good model for predicting language outcome.
Detailed Description
Background & objectives:
Language impairment after aphasic stroke is both common and debilitating. However the mechanisms of language recovery after aphasic stroke is not fully understood. Investigators plan to detect the changes of functional and structural language networks after aphasic stroke by high-resolution MRI.Then Combined analyse functional and structural language network changes, establishing a prediction model for language outcome.
Methods:
The proposed study is a observational trial that will include 50 patients diagnosed with post stroke aphasia from the neurology clinics at The First Affiliated Hospital, Zhejiang University. Aphasia battery of Chinese(ABC) and functional magnetic resonance imaging (MRI) will be performed at acute(~2weeks),subacute(3 months) and chronic phase(6months). Only routine drug therapy will be used.

Outcomes
Primary Outcomes
Resting state functional connectivity changes
Time Frame: 3 months
The study uses resting state functional MRI(rs-fMRI) to measure changes of functional connectivity across regions after a spontaneous recovery.
Secondary Outcomes

- White matter Integrity(6 months)
- Brain response change(6 months)
- Aphasia Battery of Chinese, ABC(6 months)
