Each eye movement ends up in a fixation point, which allows the brain to process the incoming information and to program the following saccade.

Eye movements were recorded with an eye tracker, with a sampling rate of 1000 Hz.\u0000\u0000\u0000RESULTS\u0000Analysis of eye movements during reading revealed that O-LOAD displayed more fixations, shorter saccades and shorter fixation durations than controls.\u0000\u0000\u0000CONCLUSION\u0000The present study shows that O-LOAD evidenced alterations in their eye movements during reading.

Chronic kidney disease (CKD) is highly prevalent in the elderly population closely associated with the occurrence of dementia. Recent epidemiological and experimental studies suggest a potential association of CKD with AD. Both diseases share a panel of identical risk factors, such as type 2 diabetes and hypertension. However, the relationship between CKD and AD is unclear. Lower clearance of a panel of uremic toxin including cystatin- C, guanidine, and adiponectin due to CKD is implied to contribute to AD pathogenesis. In this review, we summarize the current evidence from epidemiological, experimental, and clinical studies on the potential contribution of uremic toxins to AD pathogenesis. We describe outstanding questions and propose an outlook on the link between uremic toxins and AD.</p>","PeriodicalId":10810,"journal":{"name":"Current Alzheimer research","volume":"19 2","pages":"104-118"},"PeriodicalIF":2.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39836758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
