HISTORY
Strokes have been around for almost two centuries now. Various technologies have been created to combat this medical condition and the leading technology in this fight are electroencephalograms or EEG

EEGs were first recorded to have tracked electrical potentials from the cortexes of animals and introduced to the field of neurology

1935 - the first EEGs were made clinically available after reporting correlations between seizures and brain abnormalities

2017/2018 - Portable stroke detection devices are created but can only detect extreme hemorrhagic strokes and are inaccurate

1924 - Hans Berger records the first human electrical potentials using an EEG, on both damaged and healthy scalps
1947 - American EEG Society (now known as the American Clinical Neurophysiology Society) and other EEG laboraties were formed
