For the first time, Northwestern Medicine scientists have pinpointed the location of dysfunctional brain networks that lead to impaired sentence production and word finding in primary progressive aphasia (PPA), a form of dementia in which patients often lose their language rather than their memory or thought process.
With this discovery, the scientists have drawn a map that illustrates three regions in the brain that fail to talk to each another, inhibiting a person's speech production, word finding and word comprehension. For example, some people can't connect words to form sentences, others can't name objects or understand single words like "cow" or "table."

Awesome. Now that it has been identified, I wonder how soon it will be before they see some progress with therapy.
