A Biomedical Device for Early Detection of Symptoms of Mild Cognitive Impairment (MCI) and Alzheimer Disease (AD)

The present study aims to design and implement a biomedical device helps in the diagnosis of mild cognitive impairment (MCI) and Alzheimer disease (AD). It is an electronic device that provides information helps in the early diagnosis of people suffering from (MCI) in current time which may develop into (AD) in the future. The design was based on the event related potential (ERP) principles with audio stimulation, by acquiring the stimulated brain waves from (P3 and P4) regions in the parietal lobs. The audio stimulated signals that pass through a series of amplifications with gain of approximately 880x and filtering processes and then recoded as sound waves to be analyzed by MATLAB resulting in a final wave that helps in the diagnosis of (MCI) or (AD).
