Alzheimer's disease (AD) is a progressive and devastating neurodegenerative disorder that affects a significant portion of the elderly population and is increasing globally. Recent advancements in disease-modifying therapies have brought hope for slowing or preventing disease progression and improving patient outcomes. However, timely diagnosis and early intervention are crucial for maximizing the likelihood of successful treatment. Clinicians, families, and researchers need to be aware of the importance of early recognition and diagnosis of AD, as well as the latest evidence on biomarkers that aid in early diagnosis. Additionally, understanding the mechanisms of action, efficacy, and safety data for new and emerging disease-modifying therapies is essential.
