Smartphone Brain Scanner: A Novel EEG System
The study uses the Smartphone Brain Scanner framework recently developed by Arkadiusz Stopczynski (coinvestigator of the project) and colleagues, to investigate its accuracy in diagnosing epilepsy.
This is a multi-platform, real-time, and portable EEG system consisting of software and hardware, compatible with multiple commercially-available, off-the-shelf mobile devices, such as Android mobile phones and tablets. The device has several advantages for low- and middle-income countries, including (1) portability of the software to be used with multiple mobile technologies including smartphones, tablets, and computers, (2) software compatibility with existing mobile devices, (3) use of consumer-grade EEG headsets that are low cost (~300 dollars), (4) no need for paper tracings or ink, (5) no need for an expert operator, targeting the end-user such that any person can take the EEG recording on a patient with minimal training, (6) storage and electronic transmission of large amounts of data, including EEG tracings lasting for 12 hours or longer, and (7) battery operated mobile devices and EEG headsets, allowing for operation with limited electricity access.1-2
Testing the Smartphone Brain Scanner
In this study, enrolled participants will receive a smartphone and stationary EEG in Bhutan in order to compare and contrast key features of the EEG including epileptiform activity, background activity, and final diagnosis by a trained EEG reader. The aim is for a positive and negative predictive value of at least 80% each when comparing the smartphone and stationary (gold standard) EEG recording devices.
