Neural Speed of visual information processing is delayed in Early Stages of Alzheimer’s Disease

22 May 2019

Cognetivity’s Chief Scientific Officer and Co-Founder, Dr. Seyed-Mahdi Khaligh-Razavi will presented results detailing the ICA platform’s ability to detect subtle changes in the temporal dynamics of brain activity in subjects with Mild Cognitive Impairment (MCI) and mild Alzheimer’s disease (mild-AD).

Significantly, the research showed a delay in neural speed of visual information processing in participants with cognitive impairment (MCI and mild-AD) compared to age-matched healthy controls, suggesting that speed and accuracy of processing visual information are negatively affected in MCI and early stages of AD. This adds to the growing body of evidence on the suitability of visual information processing, as used by the ICA, for screening subtle cognitive impairments which can be detected before the onset of more severe cognitive symptoms in AD. The ICA has been shown to be able to detect changes in performance in those areas of the brain associated with the earliest signs of neurodegeneration in conditions such as AD.
