Today, I review, link to, and embed Imaging of dementia and brain ageing from The Neuroradiologist.
All that follows is from the above resource.
Part 1 of an imaging presentation on the neuroradiology of dementia and normal brain ageing. In this presentation I mainly focus on how to evaluate imaging studies of ageing patients suspected of having dementia, how to use various scales for the evaluation of brain atrophy and white matter changes, and the spectrum of findings that can be seen in elderly patients.
In part 2 the imaging findings in specific neurodegenerative diseases will be discussed in more detail.
