Summary

Searching electrical activity registered by EEG in acute ischemic and hemorrhagic stroke and comparing these parameters to the poststroke recovery patterns to investigate the role of EEG as a differentiation tool and as a predictor of post-stroke recovery.

Detailed description

In this study, EEG will be performed on each patient included; within 72 hours of the onset of the stroke. The EEG device will be used within the intended use as described in the user manuals. The electrodes are put on the patient's head, and the EEG signal is recorded for several minutes; the amplifier is used to amplify the EEG signal and reduce artifacts. A complete EEG and data will be collected at baseline and on follow-up to observe the differences in EEG patterns to perform a qualitative assessment of the EEG results. EEG patterns depend on the size and location of acute ischemic stroke, including generalized or focal slowing or both and epileptiform discharges. Abnormal neuronal activity is determined by comparing a part of the patient's brain not affected by stroke to a part of the patient's brain affected by stroke. Moreover, Abnormal blood flow is interpreted by comparing the abnormal EEG patterns in the areas of infarctions or hemorrhage to the normal brain tissue signals. The aim is to compare electric waveforms from an EEG device between patients with acute ischemic and acute hemorrhagic stroke (at baseline which is within 72 hours of the onset of acute ischemic and acute hemorrhagic stroke and through study completion, an average of 3 to 6 months).
