These transcripts and audio files were gathered as part of a larger protocol administered by the Alzheimer and Related Dementias Study at the University of Pittsburgh School of Medicine. The original acquisition of the DementiaBank data was supported by NIH grants AG005133 and AG003705 to the University of Pittsburgh. Participants included elderly controls, people with probable and possible Alzheimer’s Disease, and people with other dementia diagnoses. Data were gathered longitudinally, on a yearly basis.
Demographic data and test results from the rest of the protocol that was administered to all participants are included on the Data Spreadsheet for the Pitt Corpus available here. The first tab (readme) provides notes that may help clarify the data in the spreadsheet.
The CHAT transcript ID header tier for the participants (PAR) includes the information listed below.

Just after Thanksgiving George Miller moved in with his son's family. His granddaughter, Melanie, enjoyed listening to the wonderful stories about his childhood in the city. She asked if they could visit the house where he had lived as a child. One Friday, George and Melanie set off on their trip. The streets were crowded and George held Melanie's hand tightly. The little girl was frightened of the noisy streets and, although she did not tell her grandfather, she was pleased to return to the country.
2. Uncle Bill and Johnny (no text available)
