This systematic review examined the relationship between eye tracking metrics and cognitive dysfunction in adults with epilepsy. It included ten studies and found that individuals with epilepsy exhibited prolonged fixation duration and altered saccadic dynamics, indicating cognitive impairments that traditional neuropsychological assessments may miss. Eye tracking metrics often revealed abnormalities despite normal performance on conventional tests.
Key findings
- Individuals with epilepsy showed prolonged fixation duration and altered saccadic dynamics compared to controls.
- Eye tracking metrics detected cognitive dysfunction even when traditional neuropsychological tests were normal.
- Cognitive domains affected included attention, memory, executive control, and socioemotional processing.
Why it matters
Understanding cognitive dysfunction in epilepsy is crucial for improving patient management. Eye tracking may provide a more sensitive measure of cognitive deficits, potentially leading to better-targeted interventions and support for affected individuals.
