This paper details a theoretical research proposal to explore the efficacy of theevent-related potential (ERP) component P300 as a potential biomarker in the early detection of Alzheimer’s disease. To determine P300’s efficacy as a biomarker, an electroencephalogram test, which monitors and generates data on the electrical activity of the brain via scalp electrodes, and an auditory oddball test, which aims to assess the cognitive functioning of participants, were performed. The auditory oddball test involved playing a series of tones of two different frequencies (one is the standard tone, and the other is the target tone) for participants and having participants press a button whenever they heard a target tone. Accuracy and reaction time were recorded. The aforementioned two tests depicted a strong association between P300 and the cognitive decline of patients with Alzheimer’s Disease (AD), suggesting that this ERP component may be used for the early detection of AD, which may improve the efficacy of future treatment and the overall quality of life for diagnosed patients in the long run.
