The different sleep stages are associated with specific EEG-changes of high complexity with the occurrence of slow frequency waves during stages of deep sleep.
The aim of this study is to assess EEG changes during insulin-induced hypoglycaemia in type 1 diabetes patients in the different stages of sleep. The core questions will be:
(i) Will the pathological hypoglycaemia-related EEG-changes dominate over the physiological sleep-related changes when hypoglycaemia occurs during sleep? (ii) Is it possible to refine the mathematical algorithm to an extend, where EEG-changes during hypoglycaemia can be distinguished from sleep-related EEG-changes in all sleep stages.
(iii) If so, at what blood-glucose level will hypoglycaemia associated EEG-changes be detectable and (iv) Will patients be able to react adequately by ingestion of carbohydrates if an alarm can is given at the time of hypoglycaemia associates EEG-changes.
Twelve patients with type 1 diabetes will be studied. EEG will be recorded during graded hypoglycaemia achieved by insulin infusion and frequent glucose measurements. EEG will be analysed by the automated algorithm and by visual analysis to address the questions (i), (ii) and (iii). To address question (iv) real-time EEG-analysis with a predefined threshold defining hypoglycaemia will be performed and an alarm will aim to warn the patients of impeding hypoglycaemia. Patients will be asked to consume carbohydrates at alarm.
During the experiments the patients will be under continuous observation.
