A Pilot Study to Improve Cognitive Performance and Pupil Responses in Mild Cognitive Impaired Patients Using...

Area of Science:

• Neuroscience
• Gerontology
• Ophthalmology

Background:

• Mild cognitive impairment (MCI) is a precursor to dementia, necessitating interventions to preserve cognitive function.
• Oculomotor control circuitry shares neural pathways with cognitive behavior control.
• Developing accessible therapies for MCI is crucial for maintaining cognitive abilities.

Purpose of the Study:

• To investigate if training the oculomotor system via gaze-controlled video games can enhance cognitive functions in patients with MCI.
• To assess the impact of gaze-controlled gaming on specific cognitive domains and oculomotor responses.

Main Methods:

• A pilot study involving MCI patients playing a gaze-controlled video game for 2-3 weeks.
• A control group played the same game using a mouse.
• Cognitive assessments included the MoCA screening test and the CANTAB battery.
• Oculomotor responses (pupil and vergence) were measured using an oddball paradigm.

Main Results:

• Gaze-controlled gaming significantly improved MoCA scores, particularly in the visuospatial domain.
• The Rapid Visual Information Processing test from CANTAB showed significant improvement.
• Pupil responses to target stimuli increased in the gaze-controlled gaming group.
• The control group did not exhibit significant cognitive improvements.

Conclusions:

• Gaze-controlled gaming shows promise as a therapeutic intervention for improving cognitive function in MCI.
• The study provides preliminary evidence for the efficacy of oculomotor training through video games in MCI patients.
• Further research is warranted to explore the long-term effects and broader applications of this approach.
