Alzheimer’s disease is a progressive neurodegenerative disorder and the most common cause of dementia worldwide. It affects more than 55 million people, with millions more at risk. As the global population ages, understanding Alzheimer’s causes, early warning signs, and treatment options is more important than ever.
What Causes Alzheimer’s Disease?
Alzheimer’s is primarily linked to abnormal protein buildup in the brain. The two most studied proteins are:
Amyloid-beta: Forms sticky plaques between neurons.
Tau protein: Forms tangles inside neurons, disrupting normal function.
These abnormalities lead to neuronal damage, memory loss, and eventually, a decline in thinking, behavior, and physical functiGreat stories have a personality.

How Is Alzheimer’s Diagnosed?
Alzheimer’s diagnosis involves a combination of:
- Cognitive tests.
- Brain imaging (MRI, PET scans).
- Biomarkers in cerebrospinal fluid (CSF) or blood.
- Genetic testing in certain cases (e.g., APOE4 allele).
Newer diagnostic tools are focusing on biomarker discovery — especially using blood-based biomarkers that allow for earlier, less invasive detection.
