Alzheimer's: A Doctor’s Guide to Understanding the Disease

Have you noticed a loved one becoming increasingly forgetful or confused?

As a physician at PartnerMD, I understand how distressing it can be to watch a loved one struggle with forgetfulness, confusion, or difficulty with everyday tasks.

These early signs of Alzheimer’s disease are troubling, and the impact it has on both individuals and their families is profound.

Alzheimer's, a progressive condition, affects millions of people worldwide, and its ripple effects can be felt by everyone close to the affected person.

Alzheimer’s is one of the most common forms of dementia, but it’s important to remember that it’s more than just memory loss.

It’s a condition that touches every part of an individual's life and the lives of those around them — family, friends, and caregivers.

In this article, I’ll help you better understand Alzheimer’s by explaining its causes, symptoms, and the latest treatments. I’ll also share some insights from my experience at PartnerMD on how to manage and understand this challenging disease.

Whether you’re learning about Alzheimer’s for the first time or seeking the latest information, my goal is to provide you with the essential knowledge to navigate this difficult journey. 

What is Alzheimer's disease, and how is it different from Dementia?

Alzheimer’s disease is a neurodegenerative condition characterized by a gradual decline in cognitive abilities.

It’s the leading cause of dementia, accounting for 60-80% of cases.

While dementia is a general term for a decline in mental ability severe enough to interfere with daily life, Alzheimer’s is a specific disease that affects memory, thinking, and behavior. Over time, the symptoms become severe enough to impact everyday tasks and quality of life.

Key statistics:

• Alzheimer’s affects over 6 million Americans, with the number expected to rise as the population ages.
• It predominantly affects individuals over the age of 65, although early-onset Alzheimer’s can occur in people as young as their 40s or 50s.
• Women are at a higher risk than men, likely due to their longer life expectancy.

The hidden risks: What causes Alzheimer's and who is most at risk?

While the exact cause of Alzheimer’s is still unknown, research suggests it’s likely due to a combination of genetic, environmental, and lifestyle factors.

Genetics & lifestyle factors: 
Individuals with a family history of Alzheimer’s may have a higher risk of developing the disease. Other risk factors include:

• Age: The most significant risk factor. The risk increases significantly for people over the age of 65.
• Gender: Women are more likely to develop Alzheimer’s than men.
• Medical conditions: Conditions such as hypertension, heart disease, and diabetes can increase risk.
• Lifestyle: A healthy lifestyle — regular exercise, a balanced diet, and staying mentally and socially active — may reduce the risk of Alzheimer’s.

While you can’t change your age or genetics, adopting a heart-healthy lifestyle may reduce your risk of cognitive decline. 

Spotting the early signs: How to recognize Alzheimer’s symptoms before it’s too late

Alzheimer’s typically progresses through several stages, and it’s important to recognize the early signs, as timely intervention can help manage symptoms more effectively.

Early signs of Alzheimer’s:

• Memory loss, especially forgetting recently learned information.
• Difficulty completing familiar tasks, like managing finances or preparing a meal.
• Confusion about time or place.
• Trouble with visual and spatial relationships, such as judging distance or misplacement of things.
• Problems with language, including difficulty finding the right words or following conversations.

Progression of the disease:
As Alzheimer’s progresses, symptoms become more severe. Individuals may experience:

• Increased confusion and disorientation.
• Significant changes in mood, behavior, or personality.
• Difficulty recognizing loved ones or recalling personal history.
• Loss of independence, with a growing need for help with basic tasks such as dressing, eating, and bathing.

Taking action: How Alzheimer's is diagnosed

Early diagnosis of Alzheimer’s is crucial for managing the disease, even though there is currently no cure.

Diagnostic tools:

Doctors use cognitive tests to evaluate memory, problem-solving, and language skills. Brain imaging, such as MRI or CT scans, can help detect brain changes associated with Alzheimer’s.

At PartnerMD, we also leverage advanced wellness tools, including Wellness University, to offer personalized wellness support for managing cognitive health and lifestyle choices.

Treatment options:

Although there is no cure for Alzheimer’s, medications can help manage symptoms. These include drugs that temporarily improve memory and cognitive function.

Ongoing research is uncovering promising new therapies, including drugs designed to target the underlying causes of the disease and slow its progression.

Recent advances, such as immunotherapy treatments aimed at reducing the buildup of amyloid plaques in the brain, offer hope for future breakthroughs.

At PartnerMD, we stay informed about these developments to provide our patients with the best care possible. 

Take control of your health: Talk to your doctor about Alzheimer's

If you or a loved one are experiencing symptoms of memory loss or cognitive decline, the best first step is to talk to your primary care physician.

This is one scenario where the value of having more time and a better relationship with your doctor truly shines. When you can build a long-term relationship and have the time needed for thorough evaluations, your doctor can provide more personalized advice that fits your unique situation.

Early detection and intervention are essential in managing Alzheimer’s, and having a trusted physician who knows you well can make all the difference.
