Accessible brain scanning for Alzheimer’s disease 

Alzheimer’s disease (AD) is the most common cause of dementia in the world and research has been able to identify brain changes associated with the degenerative process of the disease. Moreover, we now know these changes might be observed in brain scans at the onset of the mildest symptoms or even years before. Even though current treatments are limited, one thing has become clear, the sooner treatment is started the more effective it is. The problem is that brain scanning is not as easy – or cheap – as it might sound. Low-field MRI could be an option for disorders like Alzheimer's disease.
