Detection of Brain Stroke using Electroencephalography (EEG)

This paper focuses on identifying an approach to identify stroke non-invasively and cost-effectively using Electroencephalography (EEG). Brain stroke occurs when blood flow to the brain is interrupted and brain cells are deprived of oxygen and nutrients and they begin to collapse. In order to detect a brain stroke, generally a CT scan or MRI is done to identify that specific region. Due to high cost of CT-scan/MRI, we wanted to find an alternative approach that is low cost and effective also. So, CT-scan/MRI and EEG data of the patients suffering from stroke within 48 hours after the onset was taken. The current research analysis is based on detecting the electrical current density different regions of the brain and comparing it with CT-scan/MRI images. Cross-sectional studies show the electrical current density of the cortical surface under hemorrhagic and ischemic stroke conditions. All the patients were examined hemorrhagic or ischemic stroke based on CT-scan/MRI.
