Methods to Enhance Verbal Communication between Individuals with Alzheimer's Disease and Their Formal and Informal Caregivers : A Systematic Review

Abstract EN

Alzheimer's disease is the leading cause of dementia in older adults.

Although memory problems are the most characteristic symptom of this disorder, many individuals also experience progressive problems with communication.

This systematic review investigates the effectiveness of methods to improve the verbal communication of individuals with Alzheimer's disease with their caregivers.

The following databases were reviewed: PsychINFO, CINAHL, EMBASE, MEDLINE, REHABDATA, and COMDIS.

The inclusion criteria were: (i) experimentally based studies, (ii) quantitative results, (iii) intervention aimed at improving verbal communication of the affected individual with a caregiver, and (iv) at least 50% of the sample having a confirmed diagnosis of Alzheimer's disease.

A total of 13 studies met all of the inclusion criteria.

One technique emerged as potentially effective: the use of memory aids combined with specific caregiver training programs.

The strength of this evidence was restricted by methodological limitations of the studies.

Both adoption of and further research on these interventions are recommended.
