What is Alzheimer’s disease?
Alzheimer’s disease is a condition that slowly affects the brain, leading to problems with memory, thinking, and behavior. It is the most common type of dementia. Over time, brain cells become damaged and stop functioning properly, leading to symptoms that gradually worsen.
The exact cause isn’t fully understood, but several factors may increase risk:
- Aging
- Family history or certain genes
- Changes in brain proteins
- Lifestyle and environmental influences
Symptoms
Alzheimer’s disease often begins with mild changes and becomes more noticeable as it progresses.
Common symptoms include:
- Memory loss that disrupts daily life
- Difficulty completing familiar tasks
- Trouble finding words or following conversations
- Confusion about time or place
- Poor decision-making or judgment
- Changes in mood, personality, or behavior
- Loss of interest in activities
- Difficulty recognizing family and friends in later stages
How is it diagnosed?
There is no single test for Alzheimer’s disease. Healthcare providers use a combination of tools to diagnose.
This may include:
- A detailed medical history and symptom review
- Memory and thinking tests
- Blood tests to rule out other conditions
- Brain imaging, such as MRI or CT scans
These steps help providers understand what’s causing symptoms and rule out other treatable issues.
How is it treated?
While there is no cure for Alzheimer’s disease, treatment focuses on managing symptoms and supporting daily life.
Early treatment options may include:
- Medications to help with memory and thinking
- Support for mood, sleep, or behavior changes
Ongoing care may involve:
- Regular physical activity
- Social engagement
- Structured daily routines
- A safe and supportive home environment
As the condition progresses, additional care and assistance with daily activities may be needed. Some individuals benefit from specialized memory care services in later stages.
