Advances in neuroimaging and fluid-based biomarkers have provided a new window of opportunity in Alzheimer’s disease (AD) research: it is now possible, in research, to know who has AD neuropathology well before the onset of symptoms. However, brain imaging and fluid assays are expensive and inaccessible, and do not predict when someone will exhibit signs and symptoms of dementia. Furthermore, the discovery of AD biomarkers has spurred a multitude of clinical drug trials targeting amyloid plaques and tau tangles; although some of these drugs, such as aducanumab (Aduhelm™), have been shown to effectively remove amyloid plaques, their clinical benefit remains questionable and controversial. As a result, sensitive measures of cognitive and functional decline are needed for disease monitoring and response to treatment in clinical trials. The Cognitive-Communication in Aging and Neurogenic Disorders Lab (CCANDL) works toward developing sensitive measures using existing cognitive tests and language samples to meet this need. In this talk, we will describe methodology including language transcription and coding, item-level and latent profile analyses, and linear mixed effects models. Biomarker acquisition procedures will be described from the research coordinator’s perspective. Finally, we will discuss how we are applying these methods to capture moments of lucidity in individuals living with dementia who are nearing end of life.
