Abstract: Dementia, especially Alzheimer’s disease, is increasing due to population ageing and is projected to nearly triple by 2050. Understanding and identifying common behaviours such as apathy, depression, and wandering can enable caregivers and medical professionals to enhance the quality of care for patients and implement appropriate interventions to mitigate cognitive decline. This paper analyses localization data collected from patients with mild cognitive impairment and Alzheimer’s disease residing in a healthcare facility. In particular, metrics and behavioural indices are computed to classify the behaviour of individuals. The proposed method was initially applied to the localization data of seven residents, each exhibiting distinct behaviours. Subsequently, validation was conducted using data from 46 patients monitored over three months. Classification results were compared with the observations made by healthcare operators and physicians. The study demonstrated a high level of accuracy in classifying patients into different behavioural domains, such as wandering and depressed–apathetic, with 42 out of 46 cases correctly classified.
