Method and Apparatus for Prediction and Warning of Hypoglycaemic Attack
First Claim
1. Method for warning of imminent hypoglycaemic attacks for people such as diebetics characterized in that the warning is based on analysis of one or more EEG signals from the person without the use of ECG signals.

Abstract
The present invention includes a method and device for warning of hypoglycaemic attacks, which is a big problem for especially diabetics, who are in insulin treatment. It is estimated that about 1 million people have a decreased quality of life as a result of hypoglycaemic attacks. The invention collects EEG signals from people, who must be supervised and analyses these in order to detect characteristic changes in the EEG signals, which occurs in advance of a hypoglycaemic attack. In a preferred embodiment the EEG signals are collected with subcutaneously placed electrodes and the signals are lead via wires drawn under the person'"'"'s skin to a similar subcutaneously placed signal processing unit. The signal processing analyses the EEG signals and when the pre-seizure characteristics signal changes are detected, a warning signal is given to the person from an alarm giver build into the signal processing unit, e.g. in form of a vibrator. When a person detects a warning signal, the person can prevent the hypoglycaemic attack by e.g. consuming a sugary food.

- 9. Device for warning of imminent hypoglycaemic attacks for people such as diabetics characterized in that the device collects the EEG signal from two or more electrodes and by signal analysis identifies pre-seizure characteristic changes in the EEG signal such as a decrease in frequency content and an increase in amplitude and gives a warning signal after identification of the characteristic EEG changes and without the use of ECG signals.
