Signs of glucose intolerance -- a form of prediabetes -- are common in stroke patients. Researchers from the Juntendo University School of Medicine, Japan, investigated 427 stroke patients. Approximately two-thirds of the patients had glucose intolerance, based on the findings of an oral glucose tolerance test. One-fourth of the patients who had experienced an ischemic stroke (the most common type) had previously undiagnosed type-2 diabetes.
