The Stages Of Alzheimer’s Disease

Alzheimer’s disease is a brain disorder that causes memory loss, confusion, changes in personality, and gradual loss of independence. It is a type the most common type of dementia. At first, people with this disease have only a small amount of memory loss and confusion. This is called cognitive decline. But over time, these symptoms get more severe.

The disease progresses through 3 main stages of symptoms. In the final stage, people with Alzheimer’s disease may be unable to talk with family members or know what is going on around them. In this article, we shall discuss the stages of Alzheimer’s disease.

The progression of Alzheimer’s disease is generally categorized into four stages:

  • Preclinical or prodromal stage
  • Early or mild stage
  • Middle or moderate stage
  • Late or severe stage

These stages are generalized guidelines that can help people with Alzheimer’s disease and their loved ones know what to expect as the condition progresses. They can help people prepare for the road ahead and make decisions about their medical care.

However, it’s important to note that everyone experiences Alzheimer’s disease differently, and the timing and severity of their symptoms can differ. As a result, every individual may move through these stages at different rates. In some cases, the stages may even overlap, making it hard to determine exactly which stage the person is experiencing.

Preclinical Stage Alzheimer’s Disease

Alzheimer’s disease is caused by harmful changes in the brain that start before any symptoms appear. These changes can begin several years or decades before symptoms become noticeable. This period is referred to as the preclinical stage of Alzheimer’s disease.

It can be hard to diagnose Alzheimer’s disease in this stage as the person doesn’t have any symptoms. However, imaging scans can detect the presence of a protein called amyloid in the brain. Alzheimer’s disease is characterized by deposits of amyloid protein in the brain, which interfere with the brain’s function.

Early Stage Alzheimer’s Disease

In the early stages of Alzheimer’s disease, people may have difficulty with:

  • Remembering names, particularly of people they’ve recently met
  • Finding the right words to express what they want to say
  • Recalling newly learned information such as recent events or something they’ve just read
  • Keeping days, dates, and times straight
  • Keeping track of their belongings and valuables
  • Performing daily tasks
  • Concentrating on work
  • Handling money and paying bills
  • Planning and organizing
  • Exercising sound judgment

At this point, the person probably seems healthy and is likely able to drive, work, participate in social activities, and function independently. They may occasionally forget where they’ve kept their keys or the sugar, but probably won’t have any trouble remembering familiar names, faces, and places.

The person may be aware of their forgetfulness, although it may be mistaken for normal signs of aging. Friends, family members, and neighbors may also start to notice the person’s memory lapses as they start to become more frequent.

Middle Stage Alzheimer’s Disease

The middle stage is the longest—it can sometimes last years.

Alzheimer’s disease is often diagnosed during this stage because the symptoms become more evident and it becomes apparent they are not part of the normal course of aging.

These are some of the symptoms of middle-stage Alzheimer’s disease:

  • Severe memory loss and confusion
  • Difficulty remembering their own name, family members, address, telephone number, and details from their personal history, such as which school they went to
  • Tendency to wander and get lost
  • Confusion about where they are and what day or time it is
  • Inability to understand or learn new things
  • The trouble with cognitive tasks like reading, writing, or dealing with numbers
  • Altered sleep patterns, which may cause the person to sleep during the day and feel restless at night
  • Personality changes, causing the person to become moody, withdrawn, anxious, frustrated, tearful, angry, abusive, or aggressive
  • Difficulty with social situations
  • Unexpected or inappropriate behavior, such as refusing to bathe or taking off their clothes in public
  • Paranoid delusions, cause them to become suspicious of their loved ones
  • Repetitive compulsive behaviors, such as shredding tissues or wringing hands

During this stage, symptoms start to disrupt the person’s life. Initially, the person may be able to manage with occasional assistance. Over time, they may require a greater level of care. For instance, they may need help with tasks like selecting appropriate clothing, brushing, bathing, or getting dressed. Symptoms may often get worse in the late afternoon or night.

Late Stage Alzheimer’s Disease

The late stage of Alzheimer’s disease is characterized by:

  • Inability to sit, stand, walk, eat, swallow, or care for themselves
  • Bladder or bowel incontinence
  • Weight loss
  • Seizures
  • Skin infections
  • Difficulty with conversations, although the person may be able to say a few words or phrases
  • Loss of awareness of their surroundings

Alzheimer’s disease destroys people’s brain cells, resulting in significant mental and physical impairment. This condition eventually affects a person’s ability to think, move, function, and communicate. The person becomes extremely vulnerable to infections such as pneumonia because their inability to swallow can cause food or liquid to enter their lungs.

Over time, the person may become bedridden and require full-time care. Family members may consider hospice services to help care for the person and ensure their comfort in the final stages.

In summary, being diagnosed with Alzheimer’s disease can be distressing for the individual and their loved ones. Learning about the condition and its progression can help people prepare for the road ahead and participate in their healthcare.
