Alzheimer's disease is a progressive neurological disorder that primarily affects memory, cognition, and behavior. It is the most common form of dementia, accounting for a significant portion of dementia cases worldwide. 

 

In Alzheimer's disease, abnormal protein deposits, such as beta-amyloid plaques and tau tangles, accumulate in the brain, leading to the degeneration and death of nerve cells. This results in a gradual decline in cognitive function, including memory loss, impaired judgment, language difficulties, and changes in personality and behavior.

 

As the disease progresses, individuals may experience difficulties with daily activities, lose the ability to recognize familiar faces or objects, and may require assistance with basic tasks. Alzheimer's disease ultimately affects not only the individual diagnosed but also their family members and caregivers.

 

Although there is currently no cure for Alzheimer's disease, various treatments and interventions, including medications, therapy, and lifestyle changes, can help manage symptoms and improve quality of life for affected individuals. Early diagnosis and intervention are crucial for optimizing treatment outcomes and providing support for both patients and their families.
