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.

Oh my mouse!

Great lecture, as usual.

[ebbamarie]

That presentation is so useful in everyday practice. Thank you so much!!👏

[josenegron-soto]

Di you use the ERICA score to evaluate the entorrhinal cortex?

[أحمدعبدالرزاق-كز]

Is ventricular system size has a role in judgment of brain atrophic changes?

[gabrielluiscinco]

Very insightful. Thank you. If lets say imaging was done but not necessarily for assessment of dementia. If i were to assess for global cortical atrophy and found it was appropriate for age. Is there a need to assess for focal atrophy?

[tonyrad]

how to ddx perivascular robbin space with lacunar infarct?

[gabrielluiscinco]

Just clarification in using the GCA scale. What if its predominantly frontal or asymmetric for example. Do i say grade them individually or base the scale on the worst one and then say its focal/asymmetric?
