Anomia is the inability to access and retrieve the intended words during language production, and is a cardinal feature of the acquired neurogenic language disorder known as aphasia. Aphasia affects 2.5-4 million people in the US and, given the aging trend in the population, the incidence of aphasia will increase in the coming decades. Communication difficulties have a significant impact on the health-related quality of life of people with aphasia (PWA), and are associated with substantial healthcare costs. As such, diagnosis and assessment of word retrieval is essential.
