    Objectives: The purpose of this assessor-blinded, randomised controlled trial was to determine the effect of computerised cognitive training (CT) on executive function, processing speed and working memory in 61 people with mild-to-moderate dementia. Methods: The primary outcomes were forward Digit Span and Trail Making Tests (TMT) at the completion of the 6-month intervention. Secondary outcomes included cognitive and physical performance, rate of falls, participant and caregiver's quality of life and usability and adherence to the CT program. The study was registered with the Australian and New Zealand Clinical Trials Registry (ACTRN12617000364370). Results: Intervention group (n = 31) participants averaged 81 min of CT per week, and system usability scores were acceptable (participants: 68.8 ± 22.1; caregivers: 79.4 ± 23.5). There were no statistically significant differences in cognitive or physical performance outcomes between the intervention and control groups at 6- or 12-months (between-group differences [95% CI] for primary outcomes at 6-months: Forward Digit Span −0.3 [−0.8, 0.3]; TMT-A 2.7 s [−14.1, 19.5]; TMT-B −17.1 s [−79.3, 45.2]). At the 12-month follow-up reassessment, the intervention group reported significantly more depressive symptoms and had lower caregiver-rated participant quality of life and higher caregiver quality of life compared to control. Conclusions: This study showed no benefit of the CT program on working memory, processing speed and executive function. Future studies are required to better understand how CT can be used to improve cognitive and physical functioning in older people with mild–moderate dementia.
