EEG and SPECT Changes in Acute Ischemic Stroke

Acute ischemic stroke is one of the prominent roots of mortality and morbidity all over the world. Core ischemic regions, penumbral regions and extra penumbral regions occur proximal or distal to arterial occlusion where the margins of ischemia are hyperemic with either one, minimal or no parenchymal damage. Electroencephalography (EEG) and single photon emission computed tomography (SPECT) remains the investigative practices that let economical, noninvasive learning of physiological and pathological actions in the human brain in acute ischemic stroke. Mutually these procedures may detect different patterns resonant of severity, prognosis, and secondary injury allied to acute ischemic stroke. Also, these readings can be intensely linked to cerebral metabolism which is sensitive to ischemia. This review summarizes the EEG and SPECT changes and their limitations in monitoring patients with acute ischemic stroke patients.
