We created a computer model with a user-friendly graphical interface that could tell an accurate and engaging story about the management of patients with behavioural and psychological symptoms of dementia (BPSD) in Alzheimer’s disease. The agent-based model was built using the AnyLogic development platform and calibrated with data on prevalence and incidence of dementia in the Australian population. The graphical user interface of the model consisted of multiple screens and was intended as a tool for information visualisation and virtual experiments. The dynamic progression of the symptoms and each patient’s individual characteristics such as age, gender and place of residence were integrated into one model. The preliminary results indicate that simulation modelling approach and application of multiple icons in graphical representation of each individual patient are efficient tools for information visualisation in agent-based model. The dual graphical representation of individual patients allowed for simultaneous display of clinical e.g. symptom-specific and non-clinical e.g. accommodation characteristics.
