21 Sep 2015 --- A study of 350,000 patients with type 2 diabetes shows that those with poor blood sugar control have 50% higher risk of being admitted to hospital in future for dementia as those with good control. The research, which suggests improving blood sugar control could prevent many cases of dementia, is by Dr Aidin Rawshani, National Diabetes Register and Institute of Medicine, Gothenburg, Sweden, and colleagues, and is presented at this year's annual meeting of the European Association for the Study of Diabetes (EASD) in Stockholm.
