Alzheimer’s Disease: Protecting Your Brain Health!

Alzheimer’s disease is a neurological disorder that gradually develops and impacts numerous individuals globally. This intricate condition not only affects those diagnosed but also their families and caregivers.

In this blog post, we will delve into the definition of Alzheimer’s disease, its important details, the distinction between Alzheimer’s and dementia, the demographic it affects, the stages, signs and symptoms, causes, diagnosis, treatment, risk reduction, and tips for caregiving.

Let us embark on this journey of comprehension.

What is Alzheimer’s Disease?

Alzheimer’s disease, a progressive type of dementia, is characterized by memory loss, impaired thinking, and behavioral changes that disrupt daily life. Dementia encompasses various conditions that negatively impact memory, cognition, and behavior, with causes ranging from brain injuries to diseases, sometimes remaining unidentified.

According to the Alzheimer’s Association, Alzheimer’s disease represents 60 to 80 percent of dementia cases, typically diagnosed in individuals aged 65 or older. If diagnosed earlier, it is commonly referred to as “younger onset” or “early onset” Alzheimer’s disease.

While there is currently no cure for Alzheimer’s, there are treatments available that can slow down its progression.

Alzheimer’s Facts

Here are some important facts about Alzheimer’s disease:

  1. Prevalence: According to the World Health Organization, there are approximately 50 million people worldwide living with dementia, with Alzheimer’s contributing to the majority of cases.
  2. Age-related: Alzheimer’s disease is more common in older adults, typically affecting those aged 65 and above. However, it can also occur in younger individuals, referred to as early-onset Alzheimer’s.
  3. Progressive Nature: Alzheimer’s is a progressive disease, meaning symptoms worsen over time. The rate of progression varies in each individual.
  4. Global Impact: As the global population ages, the number of people affected by Alzheimer’s disease is expected to rise significantly in the coming years.
  5. No Cure: Currently, there is no cure for Alzheimer’s disease. Treatment focuses on managing symptoms and improving the quality of life for individuals.

Alzheimer’s vs. Dementia

While Alzheimer’s disease is often used interchangeably with dementia, it is crucial to understand the distinction between the two:

  • Alzheimer’s Disease: A specific type of dementia characterized by memory loss, cognitive decline, and behavioral changes. It is the most common form of dementia.
  • Dementia: A broader term used to describe a group of symptoms affecting memory, thinking, and social abilities. Alzheimer’s is a specific type of dementia, but not all dementia cases are due to Alzheimer’s.

Alzheimer’s disease and dementia are closely related but not synonymous terms. Alzheimer’s is a specific disease that is one of the leading causes of dementia. Understanding the distinction between the two can help in accurate diagnosis, treatment, and management of these conditions.

Who Does Alzheimer’s Disease Affect?

Alzheimer’s disease can affect anyone, but certain factors increase the risk:

  1. Age: The risk of Alzheimer’s increases with age. Most cases occur in individuals over the age of 65.
  2. Genetics: While not everyone with a family history of Alzheimer’s will develop the disease, having a first-degree relative with Alzheimer’s increases the risk.
  3. Gender: Women are more likely to develop Alzheimer’s compared to men, possibly due to hormonal differences or longer life expectancy.
  4. Lifestyle Factors: Chronic conditions like heart disease, high blood pressure, obesity, and diabetes may increase the risk of developing Alzheimer’s.
  5. Head Trauma: Repeated head injuries or severe traumatic brain injuries can contribute to the development of Alzheimer’s disease.

To sum up, Alzheimer’s disease has a significant worldwide impact, as increasing statistics and projections suggest it is becoming a more pressing concern. It is essential to focus on raising awareness, enhancing diagnosis and treatment, and allocating resources to research in order to effectively tackle the challenges posed by this incapacitating illness.

Stages of Alzheimer’s Disease

Alzheimer’s is a disease that progresses over time, with symptoms gradually getting worse. There are seven main stages to this progression:

Stages 1–3: Pre-dementia and mild cognitive impairment

Stage 1. No symptoms are present at this stage. If you have a family history of Alzheimer’s and are symptom-free, it may be beneficial to consult a doctor for advice on healthy aging strategies.

Stage 2. The earliest signs of the disease start to show, such as forgetfulness.

Stage 3. Mild physical and cognitive impairments emerge, including reduced memory and concentration. Learning new skills may become challenging. These changes may only be noticeable to those very close to the individual.

Stages 4–7: Dementia

Stage 4. Alzheimer’s is often diagnosed during this stage, but it is still considered mild. Memory loss and difficulty in managing daily tasks are common.

Stage 5. Moderate to severe symptoms require assistance from loved ones or caregivers to ensure basic needs are met, such as eating and maintaining the home.

Stage 6. Basic tasks, like eating, dressing, and using the bathroom, require assistance at this stage.

Stage 7. This is the final and most severe stage of Alzheimer’s. Speech and facial expressions are usually lost progressively, with limited movement.

As the person moves through these stages, they will require increasing support from their caregivers.

Discuss strategies with your doctor to help manage these changes. Appropriate care can maintain comfort and quality of life for as long as possible.

It is also important to communicate your care plan with loved ones. As the disease progresses, individuals with Alzheimer’s will need more help with medical decisions.

On average, people with Alzheimer’s live for 4 to 8 years after diagnosis, although some may live up to 20 years.

Signs and Symptoms of Alzheimer’s Disease

Alzheimer's Disease Symptoms
Alzheimer’s Disease Symptoms

The signs and symptoms of Alzheimer’s disease (AD) can vary depending on the stage of the condition. Generally, the symptoms involve a gradual decline in various areas, including:

  • Memory
  • Reasoning and handling of complex tasks
  • Language
  • Understanding visual form and space relationship
  • Behavior and personality

It is important to note that individuals with AD may have difficulty recognizing their own mental decline, while loved ones may notice the signs more easily. If anyone experiences dementia-like symptoms, it is crucial to seek medical attention promptly.

Symptoms of the Mild Stage of Alzheimer’s Dementia

In the mild stage of AD, symptoms become noticeable. The most common early symptom is forgetting newly learned information, particularly recent events, places, and names. Other signs and symptoms of mild Alzheimer’s include:

  • Difficulty finding the right words to express thoughts
  • Increased misplacement or loss of objects
  • Trouble with planning and organizing
  • Difficulty in problem-solving
  • Taking longer to complete routine daily tasks

During this stage, most individuals can still recognize familiar faces and travel to familiar places without difficulty.

Symptoms of the Moderate Stage of Alzheimer’s

The moderate stage of Alzheimer’s is typically the longest stage and can persist for many years. Individuals in this stage often require care and assistance. Symptoms during this stage may include:

  • Increased memory loss and confusion, often forgetting events or details about their life
  • Growing confusion about the day of the week, season, and location
  • Poor short-term memory
  • Difficulty recognizing friends and family
  • Repetition of stories, thoughts, or events
  • Trouble with simple math
  • Needing help with self-care activities like bathing and grooming
  • Personality changes, such as agitation, depression, apathy, or anxiety
  • Development of groundless suspicions (delusions)
  • Urinary and/or bowel incontinence
  • Sleep disturbances
  • Wandering from their living area

Symptoms of the Severe Stage of Alzheimer’s

In the final stage of Alzheimer’s, symptoms are severe, and individuals require extensive care. In this stage, the person often experiences:

  • Almost total memory loss
  • Unawareness of their surroundings
  • Needing assistance with basic activities of everyday living, such as eating and walking
  • Limited ability to communicate, with speech reduced to a few words or phrases
  • Increased vulnerability to infections, especially pneumonia and skin infections

At this stage, hospice care may be appropriate to provide comfort.

It is essential to understand the signs and symptoms of Alzheimer’s disease to seek appropriate medical care and support for individuals affected by this condition.

Alzheimer’s Disease Causes and Risk Factors

Experts have not yet determined a single cause of Alzheimer’s disease, but they have identified several risk factors that may increase the likelihood of developing the condition:

  • Age: The majority of individuals diagnosed with Alzheimer’s disease are 65 years of age or older.
  • Family History: If you have a close family member who has been diagnosed with Alzheimer’s, your chances of developing the disease may be higher.
  • Genetics: Certain genes have been linked to an increased risk of Alzheimer’s disease.

It is important to note that having one or more of these risk factors does not guarantee the development of Alzheimer’s disease, but rather raises the overall risk level.

Other potential risk factors that have been associated with Alzheimer’s include:

  • Depression
  • Smoking
  • Cardiovascular Disease
  • Previous Traumatic Brain Injury

If you are interested in learning more about your personal risk of developing Alzheimer’s, it is recommended to consult with your doctor for further guidance and information.

Is Alzheimer’s Hereditary?

Researchers have identified several factors that increase the risk of developing Alzheimer’s disease, including genetic factors.

One of these genetic factors is the APOE gene, specifically the APOE ε4 form, which increases the risk of developing Alzheimer’s and is associated with earlier onset of the disease.

However, it is important to note that having the APOE ε4 form of the gene does not guarantee that an individual will develop Alzheimer’s, as some people without this gene may also develop the disease.

The presence of a first-degree relative (biological parent or sibling) with Alzheimer’s disease increases the risk of developing the condition by 10% to 30%.

Individuals with two or more siblings with late-onset Alzheimer’s disease are three times more likely to develop the condition compared to the general population.

Additionally, individuals with trisomy 21 (Down syndrome) have an increased risk for early-onset Alzheimer’s.

How is Alzheimer’s Disease Diagnosed?

Healthcare providers use various methods to determine if a person with memory issues has Alzheimer’s disease. This is necessary because there are many other conditions, particularly neurological ones, that can cause dementia and similar symptoms associated with Alzheimer’s.

In the initial stages of diagnosing Alzheimer’s, the provider will ask questions to gain a better understanding of the person’s overall health and daily life. They may also seek input from someone close to the individual, such as a family member or caregiver, to gather more information about the symptoms. The following aspects will be investigated:

  1. Overall health: The provider will inquire about the person’s general well-being and any existing medical conditions.
  2. Current medications: Information regarding the medications being taken by the individual will be gathered.
  3. Medical history: The provider will ask about the person’s past medical history, including any previous diagnoses or treatments.
  4. Ability to carry out daily activities: The person’s capability to perform routine tasks and activities of daily living will be assessed.
  5. Changes in mood, behavior, and personality: The provider will explore any noticeable alterations in the person’s mood, behavior, or personality.

In addition to the above, the healthcare provider will also:

  • Conduct a physical examination and a neurological examination.
  • Administer a mental status exam, which may involve memory tests, problem-solving tasks, attention assessments, basic math evaluations, and language assessments.
  • Order standard medical tests, such as blood and urine tests, to eliminate other potential causes of the symptoms.
  • Request brain imaging tests, such as a brain CT, brain MRI, or positron emission tomography, to either support an Alzheimer’s diagnosis or to rule out other possible conditions.

Treatment Options for Alzheimer’s Disease

There’s no cure for Alzheimer’s disease, but certain medications can temporarily slow the worsening of dementia symptoms. Medications and other interventions can also help with behavioral symptoms.

Beginning treatment as early as possible for Alzheimer’s could help maintain daily functioning for a while. However, current medications won’t stop or reverse AD.

As AD affects everyone differently, treatment is highly individualized. Healthcare providers work with people with Alzheimer’s and their caregivers to determine the best treatment plan.

FDA-Approved Medications

The U.S. Food and Drug Administration (FDA) has approved two types of drugs to treat the symptoms of Alzheimer’s disease:

  1. Cholinesterase inhibitors: These medications include Donepezil (Aricept®), Rivastigmine (Exelon®), and Galantamine (Razadyne®). They work by blocking the action of acetylcholinesterase, an enzyme responsible for destroying acetylcholine, a chemical that helps nerve cells communicate. Cholinesterase inhibitors can improve some memory problems and reduce behavioral symptoms of Alzheimer’s disease. Donepezil is also FDA-approved to treat moderate to severe AD.
  2. NMDA antagonists: Memantine (Namenda®) is FDA-approved for treating moderate to severe Alzheimer’s disease. It helps keep certain brain cells healthier. Studies have shown that people with Alzheimer’s who take memantine perform better in common activities of daily living such as eating, walking, toileting, bathing, and dressing.

Aducanumab: A New Breakthrough

The FDA has given accelerated approval for aducanumab (Aduhelm™), the first disease-modifying therapy for Alzheimer’s disease. This medication helps to reduce amyloid deposits in the brain. Aducanumab is a new medication, and researchers have studied its effects in people living with early Alzheimer’s disease. Therefore, it may only help people in the early stage.

Managing Behavior Changes

If your loved one has been diagnosed with Alzheimer’s disease, there are steps you can take to keep them comfortable in their environment and manage behavior changes. These include:

  • Maintaining a familiar environment for them without changing the layout or organization of their living space.
  • Monitoring their comfort.
  • Providing comfort objects, such as a favorite stuffed animal or blanket.
  • Trying to redirect their attention if they’re under stress.
  • Avoiding confrontation.

Medications for Behavioral Symptoms

No medication has been approved for the management of behavioral symptoms in Alzheimer’s dementia. However, certain medications may help in some people, including:

Healthcare providers usually limit the prescription of these medications to short durations and only when there are severe behavioral problems, as they may have undesirable or potentially hazardous side effects (such as dizziness that could result in falls). Alternatively, they may be prescribed after safer non-drug therapies have been attempted by your loved one.

Clinical Trials

If you or a loved one has been diagnosed with Alzheimer’s disease, it is advisable to inquire with your healthcare provider about ongoing clinical trials that may be advantageous. Scientists are currently engaged in active research on this condition and potential remedies.

Being diagnosed early often grants individuals more chances to participate in clinical trials or other research studies.

  2. Healthy Diet: Adopting a healthy and balanced diet can also lower the risk. Focus on consuming a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit the intake of processed foods, sugary drinks, and saturated fats.
  3. Mental Stimulation: Keeping your brain active and engaged through activities like reading, puzzles, learning new skills, or playing musical instruments may help reduce the risk of Alzheimer’s disease.
  4. Quality Sleep: Prioritize getting enough quality sleep. Aim for 7-9 hours of uninterrupted sleep each night. Poor sleep habits and disorders like sleep apnea have been linked to an increased risk of Alzheimer’s disease.
  5. Social Engagement: Staying socially active and maintaining strong social connections has been associated with a decreased risk of Alzheimer’s disease. Engage in activities that involve interaction with others, such as volunteering, joining clubs, or participating in community events.
  6. Chronic Disease Management: Managing chronic conditions like diabetes, high blood pressure, and high cholesterol can also help reduce the risk of Alzheimer’s disease. Follow your healthcare provider’s recommendations for monitoring and controlling these conditions.
  7. Quit Smoking: Smoking has been linked to an increased risk of developing Alzheimer’s disease. Quitting smoking can significantly reduce this risk.

It’s important to note that while these lifestyle choices may help reduce the risk, they do not guarantee complete prevention of Alzheimer’s disease. It’s always advisable to consult with a healthcare professional for personalized advice and recommendations.
