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.

thanks

[@gabrielluiscinco1935]

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?

[@gabrielluiscinco1935]

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?

[@theneuroradiologist]

Nah, I dont scrutinize my "chronische headache" MRIs for subtle asymmetrical atrophy. If it jumps to the eye and is clear, I will report it off Course

[@user-yy4pi3bw3u]

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

[@lucastonyhartono8624]

how to ddx perivascular robbin space with lacunar infarct?

[@theneuroradiologist]

A combination of location, size and presence of gliosis. Virchow-Robin spaces are generally located basally in the basal ganglia (where the lenticulostriate arteries perforate the substantia perforata anterior), tend to be smaller and are not surrounded by gliosis. Lacunar inarcts are typically located higher-up in the basal ganglia, tend to be larger and are oftne surrounded by gliosis. None of these is 100% fail-safe, but if you combine you, you can mostly say which is which.

Don't know what's the problem, I just checked and normal video?
