Participants with aphasia, presenting with anomia, dysgraphia, and
agrammatism, were recruited from three research sites, Northwestern University (n = 9), Boston University and Massachusetts General Hospital (n = 21), and Johns Hopkins University (n = 5), respectively, as part of a large-scale NIDCD funded Clinical Research Center.
It is characterized by disturbances of executive functions, visual-spatial disorganization, emotional dysregulation (blunting of affect and disinhibited and inadequate behavior), and language deficits (
agrammatism and aprosodia) [5].
The diagnosis of PNFA required gradually progressive non-fluent spontaneous speech with at least one of the following symptoms:
agrammatism, phonemic paraphasias, or anomia.

Integrating the message level into treatment for
agrammatism using story retelling.
Over the last several decades, a large part of aphasia research has focussed on persons with Broca's aphasia and
agrammatism, although these people are relatively rare in the clinical setting, comprising perhaps 1-2% of the aphasic clients seen.

comprehension deficits in cases of
agrammatism (e.g.
For example, Wernicke [1874] proposed a model with a motor centre and a sensory centre joined by a transmission route to explain the difference between Broca's aphasia (characterized by
agrammatism, the inability to form whole sentences, so that speech consists of a limited number of words and phrases used individually, and intact comprehension) and what is now known as Wernicke's aphasia (fluent but apparently meaningless grammatical speech, with many neologisms, and impaired comprehension).
