Hypoglycaemia is the most common acute complication in insulin-treated diabetes. The fear of hypoglycaemia discourages diabetic subjects from the attempt to maintain tight glycemic control, which in turn leads to increased diabetes related morbidity and mortality.

Neuroglycopenic hypoglycaemia in insulin-treated diabetic patients is associated with characteristic changes in EEG with a decrease in alpha activity and an increase in delta and theta activity. We have recently demonstrated that hypoglycaemia-associated EEG-changes can be recorded from subcutaneously placed electrodes using an automated mathematical algorithm based on non-linear spectral analysis. Experimental findings hold promises that an alarm, given at the time of EEG-changes, can help the patients to avoid severe hypoglycaemia by ingestion of carbohydrate.

This is the first larger scale trial testing the clinical applicability of a hypoglycaemia-alarm based on real-time analysis of EEG-signals.
