  • Summary

    This chapter reviews the use of biomarkers, including brain imaging. These techniques have revolutionised dementia research, although their availability for regular clinical practice is still developing. The chapter begins with a review of structural imaging techniques such as CT and MRI, and discusses the use of the dementia evolution scale. Functional techniques such as fMRI, SPECT, and PET are reviewed, including amyloid PET scans, which can identify the presence of beta amyloid protein and its distribution throughout the brain.
