Abstract
The invention relates to a warning system for epilepsy alarm, characterised in that it comprises means for taking samples from electroencephalogram signals (EEG) of a person who suffers from epileptic fits, connected to a biomedical signal amplifier and to a processing card with a microcontroller and a memory where the EEG samples of the patient are stored; a module for low-pass filtering of EEG signals with a cut-off frequency of 40 Hz and of order 20 for suppressing the noise; said microcontroller also includes means for calculating the scattering parameter of the filtered EEG signal, in which the data are sorted and the values of the 25th and 75th quantiles of the filtered EEG signals are calculated, which are associated with the previously defined scattering parameter; wherein the scattering values within the system are entered into a low-pass filtering module with a cut-off frequency of 0.5 Hz and a filtering order with a factor of 20; an analyser which analyses the processed signals to find epileptic fits in real time; said analyser conducts a sample-by-sample comparison of each of the filtered scattering values, having two detection thresholds when an epileptic fit occurs or when the fit has ended, using visual and/or acoustic alarms.
