Speech-generating device to help communication in childhood dementia

Official title: A Randomized Cross-over Trial Examining the Efficacy of Implementing a Speech-generating Device for Rare Genetic Conditions

Run by Murdoch Childrens Research Institute · NCT07039084 · Data updated 2026-11-12

This project will test whether giving children with childhood dementia a speech-generating iPad app helps them communicate better than their usual care.

Is this trial a fit for you?

Likely a good fit

Children aged 3–12 with genetically confirmed childhood dementia who are minimally verbal (<20 spontaneous words), can tap an iPad (visual-motor screening passed), have adequate hearing, are not already proficient daily users of a speech-generating device, and can participate in English-language therapy.

Probably not a fit

Children who already use a speech-generating device proficiently, who cannot reliably tap or perceive the device due to severe visual/motor/hearing impairments, or who cannot participate in English-language sessions are unlikely to benefit from this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a randomized crossover trial enrolling 38 children (ages 3–12) with genetically confirmed childhood dementia who are minimally verbal. Each child will receive both conditions in different sequences: a speech-generating device program on an iPad plus twice-weekly 1-hour therapy sessions for six weeks, and a usual-care (no device) phase. Change in communication will be measured using an individualized, patient-defined 'communicative act' chosen with the family, with additional parent-reported and family-impact measures collected as secondary outcomes. Participants must pass a visual-motor screen, have adequate hearing, not already use a speech-generating device proficiently, and be able to participate in English-language sessions at the Melbourne site.

Why it matters

Potential benefit: If successful, the device could meaningfully improve each child's ability to communicate and reduce family communication burden.

How similar studies have gone: High-tech augmentative and alternative communication (AAC) has shown benefits in other neurodevelopmental conditions, but rigorous trials specifically in childhood dementia are limited, making this approach relatively novel for this population.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Is between the ages of 3 and 12 years, inclusive, at the time of enrolment
* Has a diagnosis of a rare genetic disorder
* Passes a visual-motor screening test, therefore being able to tap on an iPad spontaneously or by imitation and has adequate hearing
* Considered "minimally verbal" with less than 50 spontaneous words (or gestalts) at baseline assessments, confirmed with the LVIS.
* Is not currently using a speech-generating device with proficiency (i.e. using the device as a main mode of communication on a daily basis).
* Is English-speaking or consents to therapy being conducted in English (parents will need to be able to complete the parent-reported measures in English)

Exclusion Criteria:

* Has an additional or dual genetic variation (as this is likely to cause multiple complications and increase variability),
* Is extremely ill or has progressed into a later stage of their disease (i.e. child has clinically significant loss of vision, hearing, fine motor skills, or is unable to adequately attend sessions due to illness),
* This is to ensure treatment is beneficial, reduce harm and reduce attrition rates.
* Lives outside of the state of Victoria (making it difficult for in-person appointments)
* Inability or unwillingness of participant or legally acceptable representative to give written informed consent.
