Abstract
In this study we applied techniques of Quantitative EEG (qEEG) and MRI on the study of diaschisis after stroke. Since diaschisis indicates a remote change in functional status. Therefore, studies capable of measuring functional activities were adopted. We examined patients at acute stage (within 72hours after stroke) and at subacute stage (after 14 to 21 days). The patients were also assessed with the Canadian Neurological Scale (CNS) in the acute stage and the CNS and Barthel index at the subacute stage. Structural MRI was the used to define the area and the extent of the stroke. Functional MRI acquired from GRE-EPI pulse sequence. The results from fMRI studies were not sensitive and specific enough for delineating phenomenon. On the other hand, the qEEG study based on crossspectral coherence analysis revealed the diaschisis effect and its evolution over time, from acute to subacute stage.
