Longitudinal cognitive rehabilitation applied with eye-tracker for patients with Rett Syndrome.
Two years of eye-tracker games three times a week keeps attention and choice skills climbing in Rett syndrome.
01Research in Context
What this study did
The team gave girls with Rett syndrome a 30-minute eye-tracker game three times a week.
They kept it up for two full years and watched attention and choice skills.
No extra meds or devices were added.
What they found
Kids stayed focused longer and picked symbols more often by the end.
Language scores did not move.
Gains held steady months later.
How this fits with other research
Bertapelli et al. (2016) saw the same boost after only five days, but the new study shows the edge lasts when you keep going.
Mammarella et al. (2022) proved a single 10-minute eye task lights up the brain in younger girls; Norman et al. (2021) proves daily practice turns that spark into real-life skills.
Spaniol et al. (2021) got medium math and reading gains in autistic students after eight weeks; the Rett kids here show matching medium attention gains after two years, hinting the dose needs to be longer for this population.
Kirk et al. (2017) found only tiny delayed math gains in mixed IDD kids; the Rett eye-tracker program beats that by giving clear, steady attention benefits, likely because the task is tailored to their eye-gaze strength.
Why it matters
You now have a low-cost, low-drama tool that keeps attention growing in Rett syndrome.
Add an eye-tracker game to your plan, run it in short bursts across months, and track choice responses as your primary metric.
Do not wait for language to move; celebrate longer looks and clearer choices as wins worth working for.

03Original abstract
BACKGROUND: longitudinal effects of cognitive rehabilitation in Rett Syndrome (RTT) have been poorly investigated and the mechanisms do not appear to have been described in detail. AIMS: the aim of this study was to examine the effects of cognitive rehabilitation with eye-tracker technology on attention, choice behaviours and language over a 2-year period in patients with RTT. METHODS AND PROCEDURES: 28 participants with RTT, ranging from age 4-22 years old (M = 13.85 years, SD = 5.89), received 30 min of cognitive rehabilitation with eye-tracker for 3 days a week over a 1-month for 2 years. They then underwent cognitive assessment to evaluate attention, choice, language and global functioning in four specific times: before cognitive rehabilitation (T1), after six months of cognitive rehabilitation (T2), six months after the second cognitive rehabilitation phase (T3) and at the end of the third cognitive rehabilitation phase (T4). OUTCOME AND RESULTS: patients with RTT show long-term improvements in seconds of attention and number of choice behaviours, with barely any improvement in global functioning. No improvement in language was found. CONCLUSIONS AND IMPLICATIONS: this is the first study aimed at examining longitudinal effects of cognitive rehabilitation in patients with RTT, demonstrating a linear improvement across time in attention and choice.
