Understanding Alzheimer’s A quick primer on dementia, symptoms, stages, risk factors, and treatment progress.
What’s the difference between Alzheimer’s and dementia?
Dementia is a general term for memory and cognitive decline that interferes with daily life. Alzheimer’s disease is the most common cause of dementia and most often affects adults over age 65, though it can occur earlier in some cases.
What are the early signs of Alzheimer’s?
Early signs may include memory lapses, difficulty finding words, confusion with time or place, and trouble completing familiar tasks. These changes often develop gradually, but they are worth taking seriously when they start affecting daily life.
What are the stages of Alzheimer’s disease?
Early (Mild): Subtle changes in memory, focus, or day-to-day function may begin. Moderate (Middle): Confusion and daily functioning challenges can become more noticeable. Severe (Late): Significant cognitive decline and loss of independence can occur.
What causes Alzheimer’s disease?
The exact cause is not fully understood. It is believed to result from a combination of genetic, environmental, medical, and lifestyle factors that affect the brain over time.
Is Alzheimer’s genetic?
A family history of Alzheimer’s may increase risk, but genetics is only one factor. Age, medical history, lifestyle, and overall health can also play a role.
Is there a cure for Alzheimer’s?
There is currently no cure, but Alzheimer’s care is changing quickly. New ways to detect the disease and new therapies continue to become available, which makes timely information more useful for deciding what to do next.
