Core Viewpoint - The article emphasizes the importance of early prevention and treatment of Alzheimer's disease, highlighting its growing prevalence in China due to an aging population, with approximately 10 million patients aged 60 and above [1]. Symptoms and Diagnosis - Alzheimer's disease primarily manifests through memory decline, language difficulties, impaired judgment, and emotional fluctuations, which can severely affect daily living abilities [1]. - Distinguishing between normal age-related forgetfulness and early Alzheimer's requires a systematic cognitive function evaluation [3]. - Early signs of Alzheimer's include significant memory loss, repetitive questioning, and changes in personality, necessitating prompt medical consultation [5]. Types of Alzheimer's Disease - Most Alzheimer's patients are over 65, but early-onset cases can occur in individuals in their 50s or younger [5]. - Cognitive impairment can stem from various causes, including neurodegenerative diseases like Alzheimer's and vascular dementia due to blood supply issues [5]. Brain Atrophy - Brain atrophy does not necessarily indicate Alzheimer's; it can be a normal physiological change with age [6]. - Distinctions between Alzheimer's-related atrophy and normal aging include the affected brain regions and the rate of atrophy progression [9]. Prevention Strategies - There are currently no specific drugs for Alzheimer's, and treatment focuses on symptom management and disease progression delay [11]. - Preventive measures include maintaining a healthy lifestyle, such as weight control, regular exercise, and a balanced diet, along with social engagement and managing cardiovascular health [11]. Mediterranean Diet - Recent studies suggest that the Mediterranean diet may reduce the risk of developing Alzheimer's, particularly in genetically predisposed individuals [13]. - The Mediterranean diet emphasizes high intake of plant-based foods, healthy fats, moderate fish consumption, and limited red meat, which may help protect brain health [15]. - The diet's benefits are attributed to its ability to reduce brain inflammation, oxidative stress, and vascular damage [17].
