Comparison of the quality of mobile and clinical EEGs

Study duration: July 2017 – March 2018

Electroencephalograms (EEGs) are an important diagnostic tool in modern medicine. Since it is not always possible to get a patient to an EEG machine, a mobile EEG device would grant medical professionals a new method to get an EEG from such patients, especially in rural or resource-austere areas. Additionally, the use of mobile EEGs can push the boundaries of brain research in collecting data in remote locations which lack access to EEG devices available in clinics or laboratories.
The main challenge which needs to be addressed is to assess whether mobile EEG devices are reliable and comparable in signal quality to the traditional EEG machines used for patients. The main task of this thesis is the collection of EEG data with mobile devices from patients and the comparison of the obtained results to a clinical EEG on a quantitative as well as qualitative level. Therefore, the procedure of the mobile EEG data collection should be as equal as possible to the traditional procedure. We assume to find evidence that mobile devices for EEGs are a good alternative to the traditional ones and supply sufficient quality for initial screening purposes, and in further development full diagnostics.

Our Study

Our study focuses on the investigation of brain currents with mobile EEG devices (electroencephalographs). For this purpose we perform a study with a mobile, wireless EEG device on patients who are hospitalized at the University Hospital of Aachen for a period of one week and who are receiving a classical EEG examination during that time, so that both examinations can be done parallel.
In our study we focus on patients with known epilepsy.
The aim of this study is to gain new insights from the practical application in the development of portable EEG devices in order to be able to estimate how suitable portable EEG devices are for clinical and academic use.
