=== Progressive expressive aphasia ===
Progressive [[expressive aphasia]] is the deterioration of normal [[language function]] that causes individuals to lose the ability to communicate fluently while still being able to comprehend single words and intact other non-linguistic cognition. It is found in a variety of degenerative neurological conditions including [[Pick's disease]], [[motor neuron disease]], [[corticobasal degeneration]], [[frontotemporal dementia]], and [[Alzheimer's disease]]. It is associated with hypometabolism<ref>{{cite journal |vauthors=Nestor PJ, Graham NL, Fryer TD, Williams GB, Patterson K, Hodges JR |title=Progressive non-fluent aphasia is associated with hypometabolism centred on the left anterior insula |journal=Brain |volume=126 |issue=Pt 11 |pages=2406–18 |date=November 2003 |pmid=12902311 |doi=10.1093/brain/awg240 |doi-access=free }}</ref> and atrophy of the left anterior insular cortex.<ref>{{cite journal  |vauthors=Gorno-Tempini ML, Dronkers NF, Rankin KP, etal |title=Cognition and anatomy in three variants of primary progressive aphasia |journal=Annals of Neurology |volume=55 |issue=3 |pages=335–46 |date=March 2004 |pmid=14991811 |pmc=2362399 |doi=10.1002/ana.10825}}</ref>
