Understanding Alzheimer’s Signs And Symptoms

Dementia is a syndrome, and Alzheimer’s disease is one of its most common types. Other common types of dementia include vascular dementia, dementia related to Parkinson’s disease, and frontotemporal dementia. Alzheimer’s disease typically presents with memory problems as its primary symptom, while other types of dementia may have different primary symptoms and pathological features.

Who does Alzheimer’s disease affect?
Alzheimer’s disease mainly affects people over age 65. The higher your age over 65, the more likely you’ll develop Alzheimer’s.

Some people develop Alzheimer’s disease before age 65 — typically in their 40s or 50s. This is called early-onset Alzheimer’s disease. It’s rare. Less than 10% of AD cases are early-onset.

How common is Alzheimer’s disease?
Alzheimer’s disease is common. It affects approximately 24 million people across the world. One in 10 people older than 65 and nearly a third of people older than 85 have the condition.

What are the stages of Alzheimer’s disease?
Alzheimer’s disease organizations and healthcare providers use various terms to describe the stages of Alzheimer’s disease based on symptoms.

While the terms vary, the stages all follow the same pattern — AD symptoms progressively worsen over time.

No two people experience AD in the same way, though. Each person with Alzheimer’s disease will progress through the stages at different speeds. Not all changes will occur in each person. It can sometimes be difficult for providers to place a person with AD in a specific stage as stages may overlap.

Some organizations and providers frame the stages of Alzheimer’s disease in terms of dementia:

Preclinical Alzheimer’s disease.
Mild cognitive impairment (MCI) due to Alzheimer’s disease.
Mild dementia due to Alzheimer’s disease.
Moderate dementia due to Alzheimer’s disease
Severe dementia due to Alzheimer’s disease.
Other organizations and providers more broadly explain the stages as:

-Mild.
-Moderate.
-Severe.

Don’t be afraid to ask your healthcare provider or your loved one’s provider what they mean when they use certain words to describe the stages of Alzheimer’s.

Causes of Alzheimer’s Disease:

The exact causes of Alzheimer’s disease are not fully understood, but several potential risk factors have been identified, including:

• Genetic factors: People with certain genetic mutations associated with Alzheimer’s disease have a higher risk of developing it.
• Environmental factors: Chronic conditions such as hypertension, high cholesterol, diabetes, and unhealthy lifestyle habits are associated with an increased risk of Alzheimer’s disease.
• Lifestyle factors: Maintaining a healthy lifestyle, including balanced diet, regular exercise, social engagement, and cognitive stimulation, may reduce the risk of developing the disease.

How is Alzheimer’s disease diagnosed?
Healthcare providers use several methods to determine if a person with memory issues has Alzheimer’s disease. This is because many other conditions, especially neurological conditions, can cause dementia and other symptoms of Alzheimer’s.

In the beginning steps of an Alzheimer’s diagnosis, a provider will ask questions to better understand your health and daily living. Your provider may also ask someone close to you, like a family member or caregiver, for insight into your symptoms. They’ll ask about:

-Overall health.
-Current medications.
-Medical history.
-Ability to carry out daily activities.
-Changes in mood, behavior and personality.
-Perform a physical exam and a neurological exam.
-Perform a mental status exam, which includes tests to assess memory, problem-solving, attention, basic math and language.
-Order standard medical tests, such as blood and urine tests, to rule out other possible causes of the symptoms.
-Order brain imaging tests, such as a brain CT, brain MRI or positron emission tomography, to support an Alzheimer’s diagnosis or to rule out other possible conditions.

What is the treatment for Alzheimer’s disease?

While there is currently no cure for Alzheimer’s disease, symptomatic treatments, behavioral therapy, and supportive care can help alleviate symptoms and improve quality of life. Pharmacological treatments mainly include cholinesterase inhibitors and NMDA receptor antagonists to improve cognitive function and behavioral symptoms.

Prevention:

Although Alzheimer’s disease cannot be completely prevented, the following strategies may help reduce the risk:

• Maintaining a healthy lifestyle: Balanced diet, regular exercise, social engagement, and cognitive stimulation.
• Management of chronic conditions: Proactively treating conditions such as hypertension, high cholesterol, and diabetes to reduce the risk of developing Alzheimer’s disease.

Caring for People with Alzheimer’s Disease:

Caring for someone with Alzheimer’s disease requires patience, understanding, and compassion. Here are some suggestions:

• Provide support and understanding: Respect the patient’s feelings and needs, and offer them adequate support and care.
• Maintain communication: Keep good communication with the patient, expressing thoughts and needs as clearly and simply as possible.
• Create a safe environment: Keep the home environment safe and comfortable, minimizing potential hazards and confusion.

In conclusion, Alzheimer’s disease is a complex and serious condition, but with early diagnosis, comprehensive treatment, and good caregiving, patients can better cope with the disease and improve their quality of life.
