Case number 10 is a 48 year old female speech therapist with word

0:05

finding difficulties. The MRI shows asymmetric left perisylvian atrophy,

0:10

just similar to like what we saw in the other case.

0:13

You can see the definite enlargement of the sulci here compared to the

0:16

normal appearing contralateral side. And this patient had an FDG PET/MRI.

0:22

Here is the surface map. We see hypometabolism in the left temporal and

0:28

the left parietal. Here is again left temporal and left parietal cortices.

0:33

But you see only on one side. Look here on the left.

0:37

This is looking from behind, which is why this is left and not

0:40

right. And here's the right, which looks normal. Here again is the left

0:43

hand side. This is another patient with logopenic progressive aphasia, again

0:49

a subcategory of Alzheimer's disease.
