Alzheimer’s disease (AD) is the most prevalent form of dementia, significantly impairing cognitive abilities such as memory and judgment. The number of dementia cases is expected to rise dramatically in the coming decades, with Alzheimer's disease accounting for 60-80% of these cases. Early detection is crucial for improving patient outcomes, yet diagnosing Alzheimer’s at its early stages remains challenging due to various clinical and perceptual obstacles. This study addresses whether Alzheimer’s can be detected in advance and the methods that can be used for early diagnosis. Using an Alzheimer's disease dataset sourced from Kaggle including 2,150 samples with 32 independent and 1 dependent variables, various classification algorithms were applied to assess performance. Feature selection techniques, including both classical and metaheuristic methods (Genetic Algorithm and Particle Swarm Optimization), were then applied to the dataset. These methods helped reduce the dataset's dimensionality while maintaining high diagnostic performance. The results showed that both metaheuristic algorithms selected 14 variables, producing the same high performance rate of 95.57% compared to the initial 32 variables. The findings suggest that Alzheimer's disease can be detected more efficiently with fewer variables, reducing analysis time and increasing diagnostic speed. Metaheuristic algorithms, particularly Particle Swarm Optimization, proved to be the most effective, enhancing the performance of 33 classifiers, while the Genetic Algorithm improved the performance of 28 classifiers. This study demonstrates that Alzheimer's can be detected with fewer variables, in less time, and with a higher accuracy rate. As a result, improved patient outcomes through reduced computational complexity and enhanced diagnostic efficiency can potentially be achieved.
