Abstract

Objects and Aims

Referrals to secondary care memory clinic has more than tripled. This has led to increased demand on diagnostic services. Conversation Analysis (CA) can help in the screening for dementia. In CA important features of the conversation between doctor, patient are analysed. In this project we created an avatar to automatically initiate conversation.

Methods

The avatar, a computerised head asked questions created by consulting neurologists to which patients responded verbally. Audio and video data was collected and a simple interface with two buttons (‘start/forward’ and ‘repeat’) on a keyboard was used. Audio recordings were transcribed and annotated by the CA expert.

Results

24 participants were recruited. All finished the trial without problems. We received feedback from participants, many saying they felt the avatar was easy to talk to. The CA expert correctly classified in 6 of 7 cases of Functional Memory disorder (FMD) and 4 out of 6 cases of neurodegenerative dementia.

Conclusion

An Avatar has potential to be a low cost addition to memory screening
