Alzheimer's Disease (AD) is a progressive condition of neurological brain disorder recognized by symptoms such as dementia, memory loss, alterations in behaviour, and impaired reasoning abilities. Recently, many researchers have been working to develop an effective AD recognition system using deep learning (DL) based convolutional neural network (CNN) model aiming deploy the automatic medical image diagnosis system. The existing still facing difficulties achieving satisfactory performance terms accuracy efficiency because lack feature ineffectiveness. This study proposes lightweight Stacked Convolutional Neural Network with Channel Attention (SCCAN) for MRI on classification overcome challenges. In procedure, we sequentially integrate 5 CNN modules, which form stack generate hierarchical understanding features through multi-level extraction, effectively reducing noise enhancing weight's efficacy. then fed into channel attention module select practical dimension, facilitating selection influential features. . Consequently, exhibits reduced parameters, making it suitable training smaller datasets. Addressing class imbalance Kaggle dataset, balanced distribution samples among classes emphasized. Extensive experiments proposed ADNI1 Complete 1Yr 1.5T, Kaggle, OASIS-1 datasets showed 99.58%, 99.22%, 99.70% accuracy, respectively. model's high surpassed state-of-the-art (SOTA) models proved its excellence significant advancement images.

This study addresses the pervasive and debilitating impact of Alzheimer’s disease (AD) on individuals society, emphasizing crucial need for timely diagnosis. We present a multistage convolutional neural network (CNN)-based framework AD detection sub-classification using brain magnetic resonance imaging (MRI). After preprocessing, 26-layer CNN model was designed to differentiate between healthy patients with dementia. detecting dementia, reutilized concept transfer learning further subclassify dementia into mild, moderate, severe Leveraging frozen weights developed correlated medical images facilitated process sub-classifying classes. An online dataset is used verify performance proposed CNN-based framework. The approach yielded noteworthy accuracy 98.24% in identifying classes, whereas it achieved 99.70% subclassification. Another validate framework, resulting 100% performance. Comparative evaluations against pre-trained models current literature were also conducted, highlighting usefulness superiority presenting as robust effective subclassification method.
