Recently, continuous glucose
monitoring (CGM) technology
has allowed researchers to capture
data furthering the understanding
of hypoglycemia-induced seizures.
Nighttime is the most vulnerable
period for hypoglycemia because
the counterregulatory
responses to hypoglycemia, even in
nondiabetic people
Patients with
diabetes who have had seizures while
wearing a CGM device in some cases
display a CGM reading of < 60 mg/dl
for more than 2 hours before the
seizure occurred
The capturing of
these seizure events on CGM suggests
that several factors, including
nocturnal timing, sleep status, and
preceding duration of hypoglycemia,
may be necessary to create the clinical
event of a hypoglycemic seizure.
