This kind of dementia as presented in the video appears to effect regions of the temporal lobes which are though to be needed for visual object recognition.So instead of a hub this could be an inability to correctly encode objects that are visually encountered and thus an inability to trigger the proper memory in other regions using visual stimuli. If a central hub structure exists then damage to it should render the individual progressively unresponsive as all representations of information are damaged so in the test the subject shouldn't even be able to reliably comprehend the task or to produce coherent words as responses with progressively worsening symptoms. What you present in the neuron model is essentially the representation of synapses between the regions and not a central hub.Distributed damage to it should be distributed damage appearing throughout the brain.
Exceptionally clear and interesting. Thank you!
