Implication

Comparative study observes reduced cerebral blood flow and impaired vascular reactivity in type 1 diabetes, indicating progressive microvascular dysfunction.

Key Points

To evaluate regional cerebral blood flow and cerebrovascular reactivity using acetazolamide challenge across individuals with insulin-dependent diabetes mellitus varying in disease duration and complications.
Measured regional cerebral blood flow via the 133Xenon inhalation technique before and after intravenous acetazolamide injection.
Evaluated 20 patients with insulin-dependent diabetes mellitus alongside 15 healthy control subjects.
Basal global cerebral blood flow was generally preserved but showed a significant inverse correlation with diabetes duration (P < 0.01), with no significant correlation to blood pressure, hemoglobin, or glycemic levels.
Acetazolamide-induced flow increases were impaired in 4 patients and borderline in 2 patients; among these poor responders, 4 presented with retinopathy and 1 had a history of transient ischemic attack.
