Hypoglycemic events in adults with type 1 diabetes occurring within 0–1 h before smartphone cognitive testing are linked to slower reaction time and poorer DSM and GCPT performance.
- Why it matters: The field lacks clarity on how long cognitive changes after glycemic events last, which limits guidance on when people should avoid cognitively demanding tasks.
- What they did: In 190 adults, 15 days of continuous glucose monitoring were paired with 3/day ecologic momentary assessment, using digit symbol matching and TestMyBrain GCPT, while multilevel models tested hypoglycemia/hyperglycemia lasting ≥15 min and rapid 5-min glucose shifts across 0–1, 1–2, and 2–3 h windows.
- The result: Associations were confined to the 0–1 h window, with no observed links for 1–2 or 2–3 h, and hyperglycemia or rapid glucose changes showed no consistent cognitive associations.
