To investigate the effect of acute hyperglycemia on brain function in adolescents with type 1 diabetes (T1D).
Twenty participants with T1D (aged 14.64 ± 1.78 years) and 20 age-matched healthy control subjects (aged 14.40 ± 2.82 years) performed two functional MRI sessions. Participants with T1D performed the first scanning session under euglycemic and the second under hyperglycemic clamp (20 mmol/L [360 mg/dL]).
Lower spatial working memory (sWM) capacity during acute hyperglycemia and significant differences in activation of regions of interest during different stages of the sWM task ( = 0.014) were observed.
Acute hyperglycemia negatively affected sWM capacity in adolescents with T1D, which is relevant for daily functioning and academic performance.
研究急性高血糖对 1 型糖尿病（T1D）青少年脑功能的影响。
20 名 T1D 参与者（年龄 14.64 ± 1.78 岁）和 20 名年龄匹配的健康对照者（年龄 14.40 ± 2.82 岁）进行了两次功能磁共振成像（fMRI）扫描。T1D 参与者在正常血糖和高血糖钳夹（20 mmol/L [360 mg/dL]）下进行了第一次扫描。
在急性高血糖期间，空间工作记忆（sWM）能力降低，在 sWM 任务的不同阶段，感兴趣区域的激活存在显著差异（ = 0.014）。
急性高血糖对 T1D 青少年的 sWM 能力产生负面影响，这与日常功能和学业表现相关。
