Clustering is commonly exploited in engineering, management, and science fields with the objective of revealing structure in pattern data sets. In this article, through clustering we construct meaningful collections of information granules (clusters). Although the underlying goal is obvious, its realization is fully challenging. Given their nature, clustering is a well-known NP-complete problem. The existing algorithms commonly produce some suboptimal solutions. As a vehicle of pattern clustering, we discuss in this article how to use a DNA-based algorithm. We also discuss the details of encoding being used here with statistical methods combined with the DNA-based algorithm for pattern clustering.

Background: Using artificial intelligence approaches enable automated assessment and analysis of speech biomarkers for Alzheimer's disease, for example using chatbot technology. However, current chatbots often are unsuitable for people with cognitive impairment. Here, we implemented a user-centred-design approach to evaluate and improve usability of a chatbot system for automated speech assessments for people with preclinical, prodromal and early dementia.

Background: Aging associates with decreased functional connectivity between brain regions linked to musical rhythm perception. Producing rhythmic music may result in strengthened functional connectivity of these regions, but more evidence is needed to support intervention design. Currently, few studies directly contrast younger and older adults' rhythmic music performance to understand brain-behavior relationships.

University College London, London, United Kingdom.
Background: Our authors from around the world met to summarise the available knowledge, decide which potentially modifiable risk factors for dementia have compelling evidence and create the most comprehensive analysis to date for potentially modifiable risk factors to inform policy, give individuals the opportunity to control their risks and generate research.
Method: We incorporated all risk factors for which we judged there was strong enough evidence. We used the largest recent worldwide meta-analyses for risk factor prevalence and relative risk and if not available the best data.

National Ageing Research Institute, Melbourne, VIC, Australia.
Background: The Promoting Independence Through quality Care at Home (PITCH) project aimed to improve outcomes for people with dementia and their carers via a co-designed training intervention for home care workers (HCWs). The results of the primary efficacy analysis of the successful stepped-wedge cluster RCT (n = 172 HCWs in 18 clusters in 7 Australian service providers) were presented at AAIC 2023.
Method: This presentation goes beyond efficacy and discusses the implementation science (process evaluation and behavioural change) and health economic analysis of the intervention.

Background: Proxy ratings primarily provided by informal caregivers are usually administered if patients living with dementia (PlwD) are cognitively unable to rate health independently. The literature is limited by the use of typically agreement statistics, reporting that proxies generally underestimate PlwD health. Additional analyses of self- and proxy-rated discrepancies in individual responses that focus on HRQoL dimensions are lacking.
