When we are reading a text, looking at an image or at our surrounding, our eyes continuously move to different fixation points. The movements are controlled by the brain toward a new fixation point where it has previously predicted that could acquire new pieces of relevant information. To do so, we need to make sense of the information distributed in the text, the image or our surrounding, i.e. we need to build an adequate representation of the whole in our memory in order to direct our foveal vision to efficiently get new clues of information. There is a clear relationship between eye movements and memory, and then it is natural to hypothesize that eye movement disorders reflect deficits in attention and working memory processes in patients with Alzheimer’s disease (AD).
We have been able to prove that deficits in the capacity of processing complex information are linked to memory-guided eye movements. Early detection and monitoring opportunities in AD patients could be substantially improved by using these ideas. Furthermore, the results obtained through our research work could become in time a simple, objective, noninvasive and economic marker for early disease detection.
