For the participants in this corpus, diagnosis of Primary Progressive Aphasia was based on primary language deficit out of proportion to other cognitive impairment, that has been progressive and the main impairment for at least 1 year. Diagnosis was based on cognitive and language testing and neurological examination and history, at Johns Hopkins Hospital, along with imaging and lab tests to exclude alternative diagnoses. Potential participants were excluded based on evidence of other diagnosis (e.g, tumor, strokes, encephalitis on MRI) or other tests that could explain the progressive language deficit, other than neurodegenerative disease.
25 of the 36 participants were seen once; 9 were seen twice; 1 was seen 3 times; and 1 was seen 4 times. 23 participants were females; 13 were males.
