There is currently no cure for the disease nor any definitive way to predict how quickly Alzheimer’s disease will progress, but this research could change that

Alzheimer’s decline could be predicted with a simple blood test already offered to those at risk of type 2 diabetes.

The disease is the most common type of dementia, with symptoms including confusion, speech and language issues, problems with moving around and behaviour changes.

There is currently no cure for the disease nor any definitive way to predict how quickly it will progress, only medicines to help relieve some of the symptoms. However, research presented at the European Academy of Neurology (EAN) Congress 2025 suggests a blood test used to detect insulin resistance could also identify patients at a high risk of cognitive decline.
