With the growing prevalence of Alzheimer’s disease and its progressive nature, a necessity arises for highly accurate and efficient early diagnostic methods. The primary purpose of this study is to improve the accuracy and efficiency of AD detection through the application of deep learning techniques to brain MRI images. The proposed model presents the combination of Dense Networks and their optimization for the peculiarities of brain imaging, establishing a novel approach in employing convolutional neural networks. The methodological approach encompassed pre-processing of the MRI data, as well as a tailored DenseNet architecture that can efficiently deal with the neuroanatomical variance inherent to AD patients. Understanding the outcomes, the deep learning algorithms are more precise in their differentiation of early-stage AD from cognitively healthy and are more advantageous than existing approaches. This finding can be understood as definitive in determining deep learning’s ability to improve AD diagnostics’ pace and dependability, with significant consequences for future diagnostics and therapeutics.
