Imaging of dementia and brain ageing.

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. 0:00 - Introduction. 1:45 - What is dementia? 9:39 - The role of Imaging. 14:28 - How to evaluate CT/MRI. 15:41 - Global Cortical Atrophy Scale 19:17 - Mesiotemporal Atrophy Scale 24:30 - Parietal Atrophy Scale (Koedam scale) 29:04 - Fazekas Scale 29:44 - Normal and abnormal ageing 30:22 - Normal vs. abnormal cerebral atrophy 44:27 - White matter changes 53:22 - Silent Brain Infarctions 59:07 - Enlarged Virchow-Robin Spaces 01:02:59 - Microbleeds 01:04:52 - Brain Iron deposition in deep nuclei 01:06:48 - Key Messages This video is brought to you by the neuroradiologist: https://twitter.com/theneuroradguy/ https://www.instagram.com/the_neurora... https://theneuroradiologist.org/ #radiology #neuroradiology #neurology #medicalstudent #neuroradiologist #theneuroradiologist #alzheimer #dementia #MRI #medical
