Summary

This trial will study how T1D patients with normal awareness of hypoglycemia (NAH) respond to three 2-hour long hypoglycemic clamps. MRS will be used to measure neurochemical profiles before and after the clamps.

Who is the study for?
This trial is for people with Type 1 diabetes who've had it for 2-30 years and have a Hemoglobin A1C below 8.5%. It's not for those pregnant, with uncontrolled high blood pressure, substance abuse issues, unable to undergo MRI scans due to various reasons like claustrophobia or having certain implants, over 300 lbs., or with a history of serious heart conditions, depression requiring hospitalization, arrhythmias in the last five years.
What is being tested?
The study tests how repeated low blood sugar episodes affect the brain's ability to detect hypoglycemia in Type 1 diabetics. Participants will experience controlled low blood sugar events while their brain responses are monitored using advanced imaging techniques.
What are the potential side effects?
Potential side effects include discomfort from low blood sugar such as shakiness, sweating, confusion and possibly fainting during the hypoglycemic clamps. The MRI may cause discomfort for those who are claustrophobic or sensitive to lying still.
