Method and apparatus for prediction and warning of hypoglycaemic attack
First Claim
1. Method for warning of imminent hypoglycaemic attacks for people such as diabetics characterized in that the warning is based on analysis of one or more electroencephalographic (EEG) signals from a person without the use of electrocardiographic (ECG) signals, said method comprising:
- providing said person with a portable hypoglycaemic attack warning system comprising an interface unit implanted below the person'"'"'s skin and an externally worn unit, said implanted interface unit having connected thereto implanted EEG signal gathering electrodes and further comprising a wireless signal transmitter, said externally worn unit comprising a signal processing unit for wirelessly receiving signals transmitted by the interface unit and for performing analysis of said signals for identifying characteristics therein indicative of an imminent hypoglycaemic attack;
wirelessly receiving transmitted EEG signals in said signal processing unit and performing analysis of said signals therein so as to detect an imminent hypoglycaemic attack andgiving a warning to said person that a said attack is determined to be imminent.

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.
