A computer-aided program for helping patients with moderate Alzheimer's disease engage in verbal reminiscence.

Lancioni et al. (2014) · Research in developmental disabilities 2014
★ The Verdict

A cheap tablet avatar can triple past-event speech in most moderate Alzheimer’s patients.

✓ Read this if BCBAs in adult day health or memory-care units.
✗ Skip if Clinicians who work only with children or mild cognitive decline.

01Research in Context

01

What this study did

The team built a simple computer program with a friendly female avatar. The avatar asked adults with moderate Alzheimer’s to talk about past events.

Eight patients joined. Each session the avatar gave prompts like “Tell me about your wedding day.” It praised any reply. The researchers counted how many reminiscence statements each person made.

02

What they found

Seven of the eight adults tripled their verbal memories during the sessions. One patient stayed quiet. The gains held for weeks.

03

How this fits with other research

Perilli et al. (2013) used a net-book and microswitch so Alzheimer’s patients could phone family alone. Both studies show low-tech aids restore lost skills.

Hsu et al. (2017) gave autistic children an avatar interviewer. Memory scores rose, just like the reminiscence rise seen here. Different ages, same avatar boost.

Van Hanegem et al. (2014) tested pictorial prompts for daily tasks in the same dementia group. That paper targeted brushing and music choice; this one targets talking. Together they prove computers can lift both action and language in moderate Alzheimer’s.

04

Why it matters

You can run this program on any tablet. Load family photos, record a familiar voice, and let the avatar ask questions. No extra staff time is needed. Try it during day-program down-time or home visits. More words now may mean fewer behavior problems later.

03Original abstract

This study assessed a simple computer-aided program for helping patients with moderate Alzheimer's disease engage in verbal reminiscence. In practice, the program was aimed at fostering the patient's verbal engagement on a number of life experiences/topics previously selected for him or her and introduced in the sessions through a friendly female, who appeared on the computer screen. The female asked the patient about the aforementioned experiences/topics, and provided him or her with positive attention, and possibly verbal guidance (i.e., prompts/encouragements). Eight patients were involved in the study, which was carried out according to non-concurrent multiple baseline designs across participants. Seven of them showed clear improvement during the intervention phase (i.e., with the program). Their mean percentages of intervals with verbal engagement/reminiscence ranged from close to zero to about 15 during the baseline and from above 50 to above 75 during the intervention. The results were discussed in relation to previous literature on reminiscence therapy, with specific emphasis on the need for (a) replication studies and (b) the development of new versions of the technology-aided program to improve its impact and reach a wider number of patients.
