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.
