Would you like to understand how brain scans are interpreted?
A project called ‘Seeing Dementia’ allows you to see the effect dementia can have on the brain, learn one way in which brain scans can be used to help diagnose dementia, and try yourself to see what it is like to perform visual assessments of the scans. The project aims to compare expert’s ratings with non-expert ratings from members of the public to see how variable people are in using the visual rating scale. Seeing Dementia focuses on one particular part of the brain – the hippocampus – which is an area that is particularly affected in typical memory-led Alzheimer’s disease. If you’d like to give it a try, visit the Seeing Dementia website. You’ll need to sign up for an account in order to take part.
