From Innocence to Devastation: How Alzheimer’s Steals Memories in These 5 Heartbreaking Stages

Alzheimer's Awareness

Alzheimer’s disease can feel like a journey full of uncertainty and fear — whether you’ve personally been diagnosed or are caring for a loved one. As someone who has navigated this landscape, I understand how important it is to grasp the progression and stages of this condition.

This article will provide straightforward insights into the stages of Alzheimer’s disease, offering ways to cope at each phase. Let’s demystify Alzheimer’s together, starting with understanding that it affects more than 6 million Americans aged 65 and older.

Key Takeaways

  • Alzheimer’s disease is a progressive brain condition that affects memory, thinking, and behavior.
  • There are two commonly used models to describe the stages of Alzheimer’s: the 3-stage model (mild/early, moderate/middle, severe/late) and the 7-stage model (ranging from no impairment to late-stage dementia).
  • In the early stages of Alzheimer’s, individuals may experience memory loss and changes in mood. As the disease progresses, memory decline worsens and daily activities become more challenging.
  • Individuals in the late stage of Alzheimer’s require around-the-clock care as verbal skills decline and dependency on others for daily activities increases.

Understanding Alzheimer’s Disease

Alzheimer’s disease is a progressive brain condition that impacts memory, thinking, and behavior. It primarily affects individuals over the age of 65 but can also occur in younger people due to genetic mutations or early-onset Alzheimer’s disease.

This disorder triggers a steady decline in mental functions, often starting with memory loss followed by deteriorations in reasoning, language skills, organization abilities, and changes in personality.

In Alzheimer’s disease, abnormal levels of amyloid proteins form plaques and tau proteins create tangles within the brain cells. These malformations primarily affect a part of the brain named the hippocampus – crucial for memory formation.

Unfortunately, scientists haven’t fully unlocked why these changes occur yet but suspect it is likely due to a combination of genetic mutation along with various environmental factors and lifestyle habits such as cardiovascular health conditions like high blood pressure or cholesterol levels paired with obesity and smoking habits.

Stages of Alzheimer’s Disease: 3-stage model

In the 3-stage model of Alzheimer’s disease, there are three distinct stages: mild/early, moderate/middle, and severe/late.

Stage 1 – Mild/Early

In the mild or early stage of Alzheimer’s, individuals often undergo noticeable shifts in their memory and thinking abilities. The disease can manifest itself through frequent recent memory losscoordination issues, and changes in mood such as depression or apathy.

These symptoms may be subtle but represent a significant change from previous levels of functioning.

As this stage progresses, forgetfulness becomes more pervasive and is not limited to recent events or new information. It starts affecting older memories too. Day-to-day tasks like managing finances and planning activities might start posing challenges for individuals at this point.

Over time, tasks that require conceptualization also become difficult leading to an overall cognitive decline associated with Alzheimer’s disease.

Stage 2 – Moderate/Middle

In this stage of Alzheimer’s disease, known as the moderate or middle phase, an individual experiences a worsening in memory loss and requires more assistance with daily activities.

This can include tasks such as dressing, bathing, and meal preparation. It is also during this stage that changes in personality and behavior may surface. Family members might notice increased restlessness, aggression or even apathy which are signs of cognitive decline associated with Alzheimer’s progression.

Life expectancy after diagnosis at this stage usually ranges from three to eleven years.

Stage 3 – Severe/Late

Individuals in stage 3 of Alzheimer’s disease experience a severe decline in their verbal skills. They may struggle to remember words or find it difficult to communicate and process information.

At this stage, around-the-clock care is typically required as individuals become increasingly dependent on others for daily activities. The prognosis for Alzheimer’s disease is generally poor, with individuals over 65 typically dying within four to eight years of diagnosis.

Common causes of death include pneumonia, malnutrition and dehydration, and other infections.

Stages of Alzheimer’s Disease: 7-stage model

The 7-stage model provides a detailed understanding of the progression and symptoms of Alzheimer’s disease. From minimal impairment to late-stage dementia, each stage offers unique challenges and insights into the journey.

Read on to learn more about these stages and how they impact individuals with Alzheimer’s and their loved ones.

Stage 1 – No Impairment

Stage 1 of Alzheimer’s disease is when there is no impairment or symptoms present. During this stage, individuals may not even realize that they have the disease because it hasn’t started affecting their memory, thinking abilities, or behavior yet.

This stage can last for years or even decades before any noticeable changes occur. It is important to note that preclinical Alzheimer’s disease falls within this stage as well. Preclinical Alzheimer’s refers to the early stages of the disease where there are no apparent symptoms but there may be subtle changes happening in the brain.

Stage 2 – Minimal Impairment/Normal Forgetfulness

Stage 2 of Alzheimer’s disease is referred to as “Minimal Impairment/Normal Forgetfulness” in the 7-stage model. This stage is characterized by mild cognitive impairment and slight changes in memory and thinking ability.

People in this stage may experience occasional forgetfulness, which is often considered a normal part of aging. However, these symptoms do not significantly impact daily functioning or independence.

The duration of Stage 2 can vary from a few months to several years depending on the individual.

Stage 3 – Early Confusional/Mild Cognitive Impairment

In the third stage of Alzheimer’s disease, known as Early Confusional/Mild Cognitive Impairment, individuals begin to experience mild changes in their cognitive abilities. Memory and thinking are primarily affected during this stage.

Symptoms may include forgetfulness, confusion, difficulty problem-solving and decision-making, and trouble finding words. Day-to-day tasks may become more challenging at this point, requiring some assistance for individuals to manage them effectively.

Stage 4 – Late Confusional/Mild Alzheimer’s disease

Stage 4 of Alzheimer’s disease is known as Late Confusional/Mild Alzheimer’s disease. During this stage, individuals may experience symptoms such as confusion, memory loss, and mild cognitive impairment.

Coordination problems, depression, and apathy can also be present. Daily tasks may become challenging, and assistance with everyday activities may be required.

Stage 5 – Early Dementia/Moderate Alzheimer’s disease

Stage 5 of Alzheimer’s disease is known as early dementia or moderate Alzheimer’s disease. During this stage, individuals may experience a decline in memory, communication, and the ability to process information.

They may have difficulty remembering personal details such as their address or phone number. Confusion about time and place is also common, making it challenging for them to keep track of appointments or navigate familiar surroundings.

In addition to memory problems, individuals in stage 5 may encounter difficulties with problem-solving and decision-making. Simple tasks like managing finances or planning meals can become overwhelming.

Stage 6 – Middle Dementia/Moderately Severe Alzheimer’s disease

In Stage 6 of Alzheimer’s disease, also known as Middle Dementia/Moderately Severe Alzheimer’s disease, there is a significant decline in memory and cognitive abilities. People in this stage may have difficulty remembering recent events or even the names of loved ones.

Their communication skills continue to worsen, struggling to find the right words or express themselves effectively. Additionally, changes in mood and behavior become more prominent during this stage, with increased agitation or aggression.

Mobility and coordination issues also become more apparent, making everyday tasks challenging for individuals in this stage.

Stage 7 – Late or Severe Dementia and Failure to Thrive

In Stage 7 of Alzheimer’s disease, individuals experience late or severe dementia and may exhibit failure to thrive. This stage is characterized by physical rigidity and contractures in major joints.

Neurological reflex changes, such as infantile or primitive reflexes, become increasingly present as the disease progresses. Pneumonia, often caused by aspiration, is the most common proximate cause of death in AD patients.

Infected decubital ulcerations, stroke, heart disease, and cancer are also common causes of death at this stage. It’s important to note that some AD patients in the final stage may die without any identifiable condition other than AD itself.

How Alzheimer’s Disease Affects the Brain

Alzheimer’s disease has a profound impact on the brain, affecting various cognitive functions. Memory decline is one of the hallmark symptoms, with individuals struggling to remember recent events or important information.

Cognitive decline extends beyond memory loss and can affect thinking abilities such as problem-solving and judgment. Language skills may also deteriorate, making it difficult for individuals to communicate effectively.

Additionally, Alzheimer’s disease can lead to changes in behavior and personality, causing mood swings and apathy. As the disease progresses, coordination problems and mobility issues may arise, greatly impacting an individual’s independence.

Coping with Alzheimer’s Disease

Coping with Alzheimer’s Disease can be challenging, but there are strategies and support systems available to help navigate the journey. From finding ways to retain independence in the early stages to seeking specialized care in the later stages, understanding how to cope with the progression of Alzheimer’s can make a significant difference for both individuals with the disease and their caregivers.
