What is Alzheimer's Disease?

Alzheimer's disease is a progressive brain disorder that affects memory, thinking, and behavior. It is the most common cause of dementia, a general term for memory loss and other cognitive abilities serious enough to interfere with daily life. Alzheimer's disease accounts for 60-80% of dementia cases.

Alzheimer's is not a normal part of aging, although the greatest known risk factor is increasing age, and the majority of people with Alzheimer's are 65 and older. But Alzheimer's is not just a disease of old age - approximately 200,000 Americans under the age of 65 have younger-onset Alzheimer's.

The exact cause of Alzheimer's disease is not yet fully understood, but it is believed to result from a combination of genetic, environmental, and lifestyle factors. The hallmark of Alzheimer's disease is the accumulation of beta-amyloid plaques and tau tangles in the brain, which lead to the death of nerve cells and the loss of brain tissue.

Early symptoms of Alzheimer's disease may include difficulty remembering newly learned information, confusion about time and place, and changes in mood and personality. As the disease progresses, individuals may experience severe memory loss, disorientation, and difficulty speaking, swallowing, and walking.

There is currently no cure for Alzheimer's disease, but treatments are available to help manage symptoms and improve quality of life. These treatments may include medications to improve cognitive function, manage behavioral symptoms, and treat coexisting medical conditions.

Research into the causes and potential treatments for Alzheimer's disease is ongoing, with a focus on identifying biomarkers for early diagnosis, developing new drug therapies, and exploring lifestyle interventions to reduce the risk of developing the disease.

If you or a loved one is experiencing symptoms of Alzheimer's disease, it is important to seek medical attention for a proper diagnosis and treatment plan. Early detection and intervention can help slow the progression of the disease and improve overall quality of life.
