# Enhancing Communication in Dementia Care: Raising the Role of Augmentative and Alternative Communication (AAC)

## TL;DR

This paper reviews how communication tools like AAC can help people with dementia communicate better, but more research and training are needed to make these tools widely effective.

## Contribution

The paper provides a narrative review highlighting gaps in AAC use for dementia and proposes future research directions to improve implementation.

## Key findings

- AAC interventions include low-tech and high-tech tools that can improve engagement and decision-making in dementia care.
- Long-term effectiveness and real-world application of AAC remain underexplored, with limited integration into standard care workflows.
- Personalization, cultural adaptation, and caregiver training are key challenges for successful AAC implementation.

## Abstract

Effective communication is fundamental to maintaining quality of life and person-centered care for individuals with dementia. However, cognitive decline progressively impairs verbal expression and comprehension, leading to social withdrawal, frustration, and increased caregiver burden. Augmentative and Alternative Communication (AAC) interventions offer promising strategies to support communication in dementia care, yet their integration into routine practice remains limited. This narrative review synthesizes current research on AAC interventions for dementia, identifies key gaps, and outlines future directions to enhance their effectiveness and implementation. We conducted a narrative review of peer-reviewed studies, reports, and guidelines on AAC in dementia care, focusing on intervention types, efficacy, and integration into care practices. Findings indicate that AAC strategies range from using low-tech solutions (e.g., memory books, visual cues, and communication boards) to high-tech system (e.g., speech-generating devices and mobile applications). While research suggests AAC can improve engagement, decision-making, and social participation, its long-term effectiveness and real-world application remain underexplored. Major challenges include the need for personalization based on disease progression, cultural considerations, and scalable caregiver training. Additionally, limited research exists on how AAC can be effectively embedded into standard dementia care workflows. Addressing these gaps is essential for optimizing AAC interventions and ensuring their accessibility and sustainability. Future research should prioritize longitudinal studies to assess sustained impact, strategies for culturally responsive adaptation, and scalable caregiver training models. Advancing AAC in dementia care has the potential to enhance person-centered communication, facilitate shared decision-making, and improve quality of life for individuals with dementia and their caregivers.
