The Impact of Augmented Reality-Based Aromatherapy Education on Symptoms in Older Adults With Early-Stage Dementia in Taiwan
This study evaluates an augmented reality (AR)-based aromatherapy education program designed for older adults with early-stage dementia in Taiwan. Participants are randomly assigned to either the intervention group, which receives AR-supported aromatherapy education sessions, or a comparison group receiving standard activities. The primary objective is to assess changes in neuropsychiatric symptoms and psychological well-being. Secondary outcomes include cognitive function and quality of life. The study aims to explore the feasibility and potential clinical benefits of integrating digital technology with non-pharmacological dementia care approaches.
The study includes multiple phases designed to examine both immediate and longer-term effects of the intervention.
Phase 1 - Structured AR-Based Aromatherapy Education (Weeks 1-4):
Participants receive the AR-based aromatherapy education program consisting of 12 structured sessions delivered over four weeks. Sessions integrate AR-guided instruction with hands-on aromatherapy learning activities.
The Augmented Reality (AR)-Based Aromatherapy Education Module was systematically developed according to the 12 symptom domains of the Neuropsychiatric Inventory Questionnaire (NPI-Q). Each unit was designed to align a specific neuropsychiatric symptom with targeted plant-based aromatic stimulation, structured educational activities, and symptom-oriented behavioral goals. The intervention consisted of 12 structured units delivered over four to six consecutive weeks (two to three sessions per week). Each session integrated AR-based digital guidance with hands-on aromatherapy activities to provide multisensory stimulation, cognitive engagement, and structured emotional regulation support.
Phase 2 - Aromatherapy Withdrawal Observation (Weeks 5-8):
Following completion of the structured sessions, aromatherapy products are discontinued to observe potential maintenance or withdrawal effects of the intervention. Participants continue routine daily activities without additional aromatherapy sessions.
Phase 3 - Personalized Aromatherapy Support (Weeks 9-12):
Based on symptom profiles and individual preferences, participants may receive guidance on the use of personalized aromatherapy products intended to support symptom management in daily life.
Phase 4 - Follow-Up Observation (Weeks 13-16):
Participants are followed to evaluate the sustainability of intervention effects. Outcome assessments are conducted to examine longer-term changes in neuropsychiatric symptoms and related health outcomes.
The comparison group receives routine care and standard daily activities at the care setting without participation in the AR-based aromatherapy education program.
