Causes and Risk Factors of Alzheimer’s Disease
Alzheimer’s Disease develops due to complex brain changes following damage to brain cells. It leads to the formation of plaques and tangles in the brain, disrupting communication between neurons. These abnormalities are central to Alzheimer’s Disease progression.
Genetics plays a vital role in Alzheimer’s Disease, particularly for early-onset cases. Individuals with a family history of Alzheimer’s Disease are at higher risk. Another significant risk factor for Alzheimer’s Disease is age. The likelihood increases dramatically after age 65.
Alzheimers Disease 2025 Guide Causes Symptoms, Lifestyle also influences Alzheimer’s Disease risk. Lack of physical activity, poor diet, smoking, excessive alcohol intake, and low social engagement may heighten the probability.
Alzheimers Disease 2025 Guide Causes Symptoms, Cardiovascular conditions such as hypertension and diabetes have also been linked to Alzheimer’s Disease.
Symptoms of Alzheimer’s Disease
Alzheimer’s Disease often starts subtly. Mild memory lapses or confusion may seem harmless, but these are common early signs of Alzheimer’s Disease.
Alzheimers Disease 2025 Guide Causes Symptoms, With time, the symptoms of Alzheimer’s Disease become more pronounced.
Common symptoms of Alzheimer’s Disease include:
- Memory loss disrupting daily life
- Difficulty solving problems or planning
