Study design

This randomized trial compared Mindlenses Professional, which combines wearable prism adaptation with tablet cognitive games, against standard paper-and-pencil rehabilitation. Sixty people with stroke completed ten sessions over two weeks. Researchers assessed memory, language, executive function, neglect, and visual perception immediately and at three and six months.

What it found

The device group had greater sustained improvement in language and hemineglect, with language differences at each post-treatment check. Memory gains became significant from three months and increased by six months. Executive measures improved in both groups.

Limits and interpretation

The trial was small and tested a specific device against one existing therapy. The abstract reports domain-level differences, not a single overall cognitive effect. Participants had stroke-related impairment; the study does not show dementia prevention or benefit in healthy people. Trial registration was retrospective. One study author, Massimiliano Oliveri, is a shareholder of the company that makes the device.
