Abstract: Alzheimer's disease is a most common neurodegenerative brain disease characterised by a problem in thinking and loss in cognition memory judgment. One of the difficult tasks is to identify symptoms of Alzheimer's at its beginning stage. Once the disease is detected it is very serious to save the life of a patient. The current medical treatments cannot cure Alzheimer's but its early diagnosis can stop the progress of disease and make the patient lead their life. So, it is necessary to diagnose Alzheimer's at an early stage using different modalities like EEG, MRI, and PET as they provide more promising results compared to a single modality. For better understanding of Alzheimer's disease, it is highly necessary to study the behaviour of Alzheimer's and existing methods in the detection process. In this paper, the progression symptoms, causes, modalities, and methods used for finding Alzheimer's disease is reviewed. The state-of-the-art literature is reviewed, and the gaps identified in the literature are discussed.
