数十年にわたり、糖尿病の診断は血糖値が一定の基準値を超えているかどうかに依存してきました。しかし現在、研究者の間では、この方法では発症の初期段階にある数百万もの人々を見逃している可能性があるという懸念が広がっています。こうした欠点を解消するため、より精度の高い検知ツールの開発が進められています。
医師は長年、糖尿病のリスクを特定するために血糖値を指標としてきました。このアプローチは多くの患者には有効ですが、明確な血糖値の急上昇を伴わずに病気が進行する一部の患者集団においては、診断が不十分となるケースがあります。

A new Karolinska Institutet study finds that children with moderate obesity face higher risks of type 2 diabetes, high blood pressure, and lipid disorders in adulthood, even without apparent risk markers. Researchers urge treatment for all such children.
New research published in Nature Medicine reveals that people with prediabetes can normalize blood sugar levels without losing weight. About one in four participants in lifestyle programs achieved this remission, offering protection against diabetes similar to weight loss methods. The key factors involve fat distribution and certain hormones.

Scientists at Washington University School of Medicine in St. Louis have developed a blood test that estimates when Alzheimer's symptoms may begin, using levels of the protein p-tau217. The model predicts onset within about three to four years, potentially aiding clinical trials and early interventions. This advance relies on data from 603 older adults in ongoing studies.
Researchers at UCL have identified a protein called LRG1 that initiates the earliest damage in diabetic retinopathy, a major cause of vision loss in adults with diabetes. In mouse studies, blocking LRG1 prevented retinal harm and preserved eye function. The findings suggest potential for new preventive treatments targeting this protein.

New research from the University of Southern California suggests that subtle declines in brain blood flow and oxygen delivery may be early indicators of Alzheimer's disease. The study, published in Alzheimer's and Dementia, used noninvasive scans to connect vascular health with amyloid plaques and hippocampal shrinkage. These findings highlight the role of brain circulation in the disease process beyond traditional markers like amyloid and tau.
