Non-pharmacological interventions are recommended as the first choice for addressing behavioural and psychological symptoms of dementia (BPSD), except when symptoms remain distressing, disabling, or dangerous [1, 2].These interventions require identifying triggers and creating appropriate coping strategies [1]. However, it is often challenging for care professionals in care settings to record BPSD and to investigate the triggers due to their workload.

1 Clinical Image A 65-year-old woman, with a medical history of depression managed with antidepressants and hypnotics, presented with dyspnea upon aspiration of scallop-containing rice porridge. At presentation, her oxygen saturation level was 95% with a 6 L/min oxygen mask. Physical examination revealed diminished breath sounds in the right upper lung. Non-enhanced chest computed tomography showed a high-density soft tissue shadow in the right upper lobe bronchus (Figure 1).
