Abstract

In this brief presentation, I talk about one finding from work currently on-going at the Centre for Language and Communication Research as part of the project 'Linguistic Perspectives on Dementia' (PI: Prof. Alison Wray). One of the questions looked at is how markers of writing style relate to known risk factors for Alzheimer's Disease. Taking short texts written by 81 participants in response to online survey questions, several quantitative measures of writing style were calculated and compared to participants' APOE e4 status and family history of Alzheimer's Disease. The particular measure of writing style reported here is p-density, which was shown by several studies to be associated with Alzheimer's Disease in late life. Controlling for age and years of education, data showed p-density was not a useful predictor of risk group based on APOE e4 and family history. There are several possible explanations for this result which need to be investigated, including the possibility that p-density and APOE e4 status pick up on independent and different types of risk of Alzheimer's Disease.
