Abstract
ABSTRACT: Alzheimer's disease (AD), a chronic neurological disorder, is an important reason of dementia, mostly among older adults. An early and accurate diagnosis of AD is necessary for timely detection and treatment. This survey review the developments the use in deep learning (DL) and machine learning (ML) methods for AD classification and detection. Focused brain network analysis to identify alterations in local and global connectivity and spectral and coherence investigations of EEG data to identify disruptions associated with AD are two research strategies that have highlighted the mechanisms behind AD. Two examples of robust deep learning models that have achieved notable precision in identifying AD using neuroimaging datasets like MRI and EEG are convolutional neural networks (CNNs) and ensemble learning. Using sleep EEG to detect mild cognitive impairment (MCI), research has demonstrated the utility of functional connectivity metrics. Furthermore, hybrid models that merge CNNs and ensemble learning have shown promise in both feature extraction and classification. Latest inventions , like gated graph convolutional networks for working with non-Euclidean data and transformer-based speech recognition models, have taken the explainable and multimodal diagnostic frameworks to the next level. This study review and gives summarize knowledge about techniques and methods used to detect Alzheimer , furthermore limitations of work and search guide.
Keywords: Electroencephalogram (EEG), mild cognitive impairment (MCI), and Alzheimer's disease (AD) Power Spectral Density (PSD)
