The slowly developing pathology of neurodegenerative diseases necessitates early diagnosis and monitored long-term treatment. Lack of effective therapies coupled with an improved rate of early diagnosis in our aging population have created an urgent need for the development of novel drugs, as well as the need for reliable biomarkers for treatment response. These issues are especially relevant for AD, in which the rate of clinical trial drug failures has been very high. Frequently used biomarker evaluation procedures, such as positron emission tomography or cerebrospinal fluid measurements of phospho-tau and amyloid beta, are invasive and costly, and not universally available or accessible. This review considers the functionality of the event-related potential (ERP) P300 methodology as a surrogate biomarker for predicting the procognitive potential of drugs in clinical development for neurocognitive disorders. Through the application of standardized electroencephalography (EEG) described here, ERP P300 can be reliably measured. The P300 waveform objectively measures large-scale neuronal network functioning and working memory processes. Increased ERP P300 latency has been reported throughout the literature in disorders of cognition, supporting the potential utility of ERP P300 as a biomarker in many neurological and neuropsychiatric disorders, including AD. Specifically, evidence presented here supports ERP P300 latency as a quantitative, unbiased measure for detecting changes in cognition in patients with AD dementia through the progression from mild to moderate cognitive impairment and after drug treatment.<\/jats:p>","DOI":"10.1155\/2022\/2104880","type":"journal-article","created":{"date-parts":[[2022,11,9]],"date-time":"2022-11-09T03:35:09Z","timestamp":1667964909000},"page":"1-13","source":"Crossref","is-referenced-by-count":47,"title":["Predictive Power of Cognitive Biomarkers in Neurodegenerative Disease Drug Development: Utility of the P300 Event-Related Potential"],"prefix":"10.1155","volume":"2022","author":[{"given":"John","family":"Olichney","sequence":"first","affiliation":[{"name":"Center for Mind and Brain, University of California, Davis, Davis, CA, USA"},{"name":"Department of Neurology, University of California, Davis, Sacramento, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiangyi","family":"Xia","sequence":"additional","affiliation":[{"name":"Center for Mind and Brain, University of California, Davis, Davis, CA, USA"},{"name":"Department of Neurology, University of California, Davis, Sacramento, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin J.","family":"Church","sequence":"additional","affiliation":[{"name":"Athira Pharma, Inc., Bothell, WA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6311-0157","authenticated-orcid":true,"given":"Hans J.","family":"Moebius","sequence":"additional","affiliation":[{"name":"Athira Pharma, Inc., Bothell, WA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","article-title":"World Health Organization-dementia","volume-title":"Home\/Newsroom\/Fact sheets\/Detail\/Dementia","author":"World Health Organization","year":"2021"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.3389\/fneur.2021.694329"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.2741\/4587"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(09)70299-6"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.18999\/nagjms.80.3.289"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.2174\/1567205012666150701103107"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1111\/cts.12491"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.4155\/cli.14.127"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1080\/13543784.2017.1323868"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1016\/j.trci.2017.10.005"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.exger.2009.09.008"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1016\/j.neurobiolaging.2019.09.008"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.15540\/nr.4.1.14"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.bcp.2010.10.002"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.4103\/0972-6748.57865"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1176\/appi.ajp.162.1.43"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsych.2006.08.006"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000281689.28759.ab"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/123.9.1948"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1093\/braincomms\/fcaa213"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijpsycho.2005.12.012"},{"key":"22","article-title":"The components of aging","volume-title":"The Oxford Handbook of Event-Related Potential Components","author":"D.
