Core Viewpoint - Alzheimer's disease is transitioning from being perceived as an "incurable disease" to a manageable chronic condition, thanks to advancements in early screening and treatment methods [1][10]. Group 1: Disease Understanding and Statistics - Alzheimer's disease is characterized by the accumulation of beta-amyloid (Aβ) and tau protein abnormalities, leading to memory decline and other cognitive impairments [3]. - In China, approximately 22% of the population aged 50 and above exhibit pathological changes associated with Alzheimer's disease, with 9.83 million diagnosed cases [3][4]. - The number of dementia patients is projected to increase significantly, with estimates suggesting that by 2030, the elderly population over 60 will reach 250 million, further raising the number of dementia cases [3]. Group 2: Diagnostic Advances - Recent breakthroughs in blood screening and low-abundance protein detection have made early diagnosis of Alzheimer's disease feasible, particularly through the use of the biomarker p-tau217 [6][7]. - The p-tau217 test has shown a high consistency of 96% with Aβ-PET, the gold standard for pathological diagnosis, and is expected to facilitate large-scale early screening [7][10]. Group 3: Treatment Developments - The treatment landscape for Alzheimer's disease is evolving into a dual system of pharmacological and non-pharmacological interventions, allowing for early intervention to maintain patients' independence [8][10]. - Two targeted Aβ drugs are expected to be available by 2024, with additional interventions for earlier pathological changes already in clinical trials [8][10]. Group 4: Societal Impact and Care Models - The burden of Alzheimer's disease extends beyond patients to families and society, necessitating a shift towards community-based care models that respect patients' dignity and promote social integration [5][12][13]. - Innovative care approaches are being adopted in some communities, emphasizing the importance of social engagement and normalcy in the lives of patients [13]. Group 5: Future Outlook - The management of Alzheimer's disease is anticipated to evolve into a chronic disease model similar to diabetes and hypertension, with early screening and affordable treatment options becoming more accessible [10][11]. - Ongoing research into new biomarkers and treatment methods, combined with advancements in brain science and artificial intelligence, is expected to further enhance early diagnosis and personalized treatment [10].
