Seven Stages Of Alzheimer’s Disease


Also called, “the long good-bye,” Alzheimer’s is one of the most feared diseases, and rightly so, as it cruelly robs its victims of their mind and memory. It is grossly misunderstood, and costs millions of dollars each year in medical costs, lost wages, and long-term care costs. Did you know there are seven stages of Alzheimer’s Disease?

Seven Stages Of Alzheimer's Disease

What Is Alzheimer’s Disease


A neurodegenerative disease, Alzheimers disease (AD) is the most common type of dementia and premature senility. This progressive mental deterioration, occurs in middle or old age, and results in degeneration of the brain. Early onset Alzheimer’s, typically, presents in those under 65 years of age, with symptoms manifesting as early as age 30 or 40. Fortunately, this group comprises only about 5 percent of those suffering from AD.

In the United States, alone, Alzheimers accounts for up to 60-80 percent of all cases of dementia, and is characterized by the accumulation of two dysfunctional proteins, beta amyloid plaque and tau, in the brains of those afflicted. However, it is possible to have amyloid plaque with no symptoms of cognitive decline, so its presence, alone, is not diagnostic of AD.

To receive an official diagnosis of Alzheimers, one must be, both, cognitively and behaviorally impaired, with a clear distinction in terms of previous and recent performance.

Alzheimer’s Disease Signs And Symptoms


In the beginning stages of AD, symptoms are mild, but as the patient progresses through the seven stages, and the deterioration worsens, they become more severe and impairing:

  • Impaired memory and cognition
  • Difficulty completing daily tasks that used to be habitual. This could be at home or in the work environment.
  • Confusion regarding time and place
  • Decreased concentration
  • A decline in problem-solving abilities and planning skills
  • Problems with word retrieval and limited vocabulary
  • Poor judgment when making decisions
  • Misplacement of items
  • Personality and behavior changes
  • Depression and other mood irregularities
  • Getting lost in familiar surroundings

Diagnosis Of AD


Diagnosis of AD involves of variety of methods, including clinical assessments, cognitive and memory evaluations, physical exams, laboratory tests, and brain imaging scans. These tests are, usually, performed by a neurologist or a doctor specializing in geriatrics.

Clinical assessments and physical exams provide extremely helpful information regarding the cognitive and behavioral abilities of the patient. Talking with family members to get a clear picture of how the decline in these abilities has progressed, is also vital.

Since AD is a type of dementia resulting in the progressive degeneration of brain cells, imaging scans can be used to help make a diagnosis, but, in themselves, aren’t conclusive, due to an overlap in what is considered abnormal brain function, and normal brain changes in the aging population. Brain imaging can help rule out causes that could, potentially, affect brain function, such as, brain tumors, strokes, Parkinson’s Disease, and mood disorders. Imaging also allows for a baseline of degeneration to be established. Tests include MRIs, CT scans, and PET scans, which are useful in detecting inhibited glucose metabolism in the brain indicative of  AD.

AD is, partly, a diagnosis of exclusion. Thyroid disorders and vitamin and mineral deficiencies, paricularly a B12 deficiency, are important to rule out in an Alzheimer’s diagnosis, as they can cause similar symptoms as AD.

What Are The Seven Stages?


There are seven stages of Alzheimer’s Disease. Initially the symptoms are mild, but as the deterioration continues its decline, the symptoms become more severe. A cruel and debilitating disease, AD, eventually, robs those afflicted, of their ability to reason, remember, and recognize those they love and associate with. It represents loss of autonomy, independence, and ultimately, loss of self. The stages are as follows:

1. No impairment: patients in this stage behave normally, and symptoms are not apparent or are nonexistent. Imaging tests, however, clearly reveal the presence of disease.

2. Very mild decline: in this stage, subtle changes begin to appear, but the person is still able to complete daily tasks and work without interference.

3. Mild decline: Irregular thinking patterns start to emerge in this stage, characterized, by forgetfulness, repeating questions, inability to make plans, and a decrease in organizational skills.

4. Moderate decline: the decline is more pronounced in this fourth stage of disease progression. This is the stage where a diagnosis becomes clear, and is referred to as mild or early-stage AD. Every day tasks, that were, previously, habitual, become more difficult to accomplish.

5. Moderately severe decline: a sharp decline is seen in this stage of Alzheimer’s and dementia. Daily tasks cannot be accomplished without assistance. The symptoms become, markedly, more severe.

6. Severe decline: the disease is severe at this stage with patients needing help with personal tasks, such as, visiting the bathroom, and getting dressed.

7. Very severe decline (clinical dementia): very severe symptoms appear in this final stage of AD, including a lack of environmental awareness and a further decline in language. Physical symptoms, such as, a decrease in muscle control are also seen.

Prevent Alzheimer’s Disease


I had a personal experience this week with a woman suffering from AD. She had been very physically and mentally active her entire life, exercising regularly, and working as a travel agent. She was in the sixth stage of AD, was in diapers, but was still able to walk, and feed herself, with her husband’s supervision. He stated that his wife first noticed symptoms of forgetfulness when she was 65. She would cry herself to sleep every night because she knew something was desperately wrong. Can you imagine the terror?

Interestingly, due to her peak physical condition, her decline had been much slower than it, otherwise, would have been. Unfortunately, it was not enough to prevent the disease, but it did mitigate her decline. What a huge plug for all of us to take better care of ourselves, throughout our lifespans, both, physically and mentally. Never will your efforts, in this regard, be a waste of time, even if you are genetically at risk to develop AD.

Diabetes, obesity, and hypertension are all risk factors for AD. Engaging in healthy lifestyle strategies like controlling your blood sugar, exercising consistently, and managing your stress, all go a long way in protecting your brain from age-related dementia and AD.

If you’d like to learn more about AD and dementia, register for free for the Alzheimer’s and Dementia Summit coming July 23-26. You won’t want to miss this fabulous event.

My Final Thoughts


Alzheimers is a frightening and heartbreaking disease. It destroys the brain function and behavioral ability of those from which it steals. The seven stages of this destructive disease begin with no obvious signs, and culminates with death, as the final stage. This disease is so very hard on the caretakers of those suffering with AD, and often, wrecks their health, as well, especially those who are not financially able to pay for assistance. It’s a sad situation as AD can go on for years – hence, the name, “the long good-bye,” and one more reason to consistently attend to your health – you never know if you’ll wind up as a loved one’s caregiver. If that happens, it will, surely, take all you have to give!

  1. Hi Holly,
    This is a very useful article about Alzheimer. I always hear about this disease but I don’t know exactly what it is. I like your article because it talks about the seven stages of Alzheimer, the diagnosis, and the prevention of it. It is really a comprehensive article regarding everything about this disease. Everyone should take care from these diseases as you said that diabetes, obesity, and hypertension are all risk factors for AD.
    I heard once that learning languages help to prevent this disease. Do you think so?
