Stage : Moderate Dementia Due To Alzheimers Disease

How Alzheimer’s Disease Progresses

Its at this stage, which lasts about two years, that Alzheimers disease is much more diagnosable. Symptoms experienced in stage three become much more pronounced. The individual becomes increasingly more forgetful and confused, requiring assistance with self-care and activities of daily living . Mood changes are much more obvious. They also frequently experience a decreased emotional response, especially in challenging situations.

Individuals with moderate dementia may:

All the difficulties they begin to face as they move into moderate dementia make it unsafe for them to continue to live on their own. For their own safety and that of others, they eventually require constant supervision. Counseling can be helpful for them and those that care for them as they progress through stage four.

What To Do Next After Learning What Stage Of Alzheimer’s Disease Your Loved One Is In

As mentioned, learning about the stage of Alzheimers disease that a loved one is experiencing helps provide perspective and context. This knowledge makes it easier to have conversations with doctors about the patients condition and how to approach future treatment options. Understanding the later stages of the disease also helps when planning for lifestyle changes, new equipment, and other items that may be needed. One of the other major benefits in understanding the overall progression of Alzheimers disease is preparing for future living arrangements, such a memory care community, that could become a preferred option during later stages of the disease. Because the cost of dementia care is high, families should begin planning as soon as possible following a diagnosis.

How Does Alzheimer’s Disease Affect The Brain

Scientists continue to unravel the complex brain changes involved in Alzheimers disease. Changes in the brain may begin a decade or more before symptoms appear. During this very early stage of Alzheimers, toxic changes are taking place in the brain, including abnormal buildups of proteins that form amyloid plaques and tau tangles. Previously healthy neurons stop functioning, lose connections with other neurons, and die. Many other complex brain changes are thought to play a role in Alzheimers as well.

The damage initially appears to take place in the hippocampus and the entorhinal cortex, which are parts of the brain that are essential in forming memories. As more neurons die, additional parts of the brain are affected and begin to shrink. By the final stage of Alzheimers, damage is widespread and brain tissue has shrunk significantly.

Is My Loved One Safe At Home

Stages Of Alzheimers Disease [INFOGRAPHIC]

There are several factors that you should consider when you evaluate the Alzheimers patients safety in their own home:

  • Alzheimers disease can cause sufferers to put themselves at risk. They may, for instance, leave pans on the stovetop, leave the gas on, ingest poisonous chemicals, or slip and fall. They may wander out into the street and get lost, or stumble into traffic. There are steps that can be taken to make the home safer, but at some point, you may feel that your loved one would be more secure in a nursing home.
  • If you are not physically strong enough to help them, then as they become more physically dependent on you, you may not be able to protect them from falls or safely lift them up.
  • Some Alzheimers sufferers develop aggressive behaviors that could put others around them at risk. Or, if they are sharing the home with family members, their forgetful behavior could cause harm to their co-habitants.

Alzheimers facilities provide round-the-clock supervision, as well as full security if your family member has a tendency to wander.

Medications To Treat The Underlying Alzheimer’s Disease Process

Aducanumab is the first disease-modifying therapy approved by the FDA to treat Alzheimers disease. The medication helps to reduce amyloid deposits in the brain and may help slow the progression of Alzheimers, although it has not yet been shown to affect clinical outcomes such as progression of cognitive decline or dementia. A doctor or specialist will likely perform tests, such as a PET scan or analysis of cerebrospinal fluid, to look for evidence of amyloid plaques and help decide if the treatment is right for the patient.

Aducanumab was approved through the FDAs Accelerated Approval Program. This process requires an additional study after approval to confirm the anticipated clinical benefit. If the follow-up trial fails to verify clinical benefit, the FDA may withdraw approval of the drug. Results of the phase 4 clinical trial for aducanumab are expected to be available by early 2030.

Several other disease-modifying medications are being tested in people with mild cognitive impairment or early Alzheimers as potential treatments.

How Much Time Can Treatment Add

Treatment will not prevent the progression of AD. It is also unclear if treatment can add time to a persons life. Ultimately, AD will progress and take its toll on the brain and body. As it progresses, symptoms and side effects will get worse.

However, a few medications may be able to slow the progression of AD at least for a short time. Treatment can also improve your quality of life and help treat symptoms. Talk with your doctor about your treatment options.

study identified several factors that affect a persons life expectancy. These include:

  • Gender: A 2004 study found that men lived an average of 4.2 years after their initial diagnosis. Women were found to live an average of 5.7 years after their diagnosis.
  • Severity of symptoms: People with significant motor impairment, such as a history of falls and a tendency to wander or walk away, had shorter life expectancies.
  • Brain abnormalities: The study also detected a connection between brain and spinal cord abnormalities and the length of life.
  • Other health problems: People with heart disease, a history of heart attack, or diabetes had shorter lifespans than patients without these complicating health factors.

Stage : Very Mild Changes

You still might not notice anything amiss in your loved one’s behavior, but they may be picking up on small differences, things that even a doctor doesn’t catch. This could include forgetting words or misplacing objects.

At this stage, subtle symptoms of Alzheimer’s don’t interfere with their ability to work or live independently.

Keep in mind that these symptoms might not be Alzheimer’s at all, but simply normal changes from aging.

Signs And Symptoms Of Alzheimer’s Disease

Memory problems are typically one of the first signs of cognitive impairment related to Alzheimers. Some people with memory problems have a condition called mild cognitive impairment . With MCI, people have more memory problems than normal for their age, but their symptoms do not interfere with their everyday lives. Movement difficulties and problems with the sense of smell have also been linked to MCI. Older people with MCI are at greater risk for developing Alzheimers, but not all of them do so. Some may even revert to normal cognition.

The first symptoms of Alzheimers vary from person to person. For many, decline in nonmemory aspects of cognition, such as word-finding, vision/spatial issues, and impaired reasoning or judgment may signal the very early stages of the disease. Researchers are studying biomarkers to detect early changes in the brains of people with MCI and in cognitively normal people who may be at greater risk for Alzheimers. More research is needed before these techniques can be used broadly and routinely to diagnose Alzheimers in a health care providers office.

What To Do If You Suspect Alzheimers Disease

Getting checked by your healthcare provider can help determine if the symptoms you are experiencing are related to Alzheimers disease, or a more treatable conditions such as a vitamin deficiency or a side effect from medication. Early and accurate diagnosis also provides opportunities for you and your family to consider financial planning, develop advance directives, enroll in clinical trials, and anticipate care needs.

What Is Mild Cognitive Impairment

Mild cognitive impairment, or MCI, is a condition in which people have more memory problems than normal for their age but are still able to carry out their normal daily activities. A doctor can do thinking, memory, and language tests to see if a person has MCI. People with MCI are at a greater risk for developing Alzheimers disease, so its important to see a doctor or specialist regularly if you have this condition.

Health Environmental And Lifestyle Factors That May Contribute To Alzheimer’s Disease

Grappling With Dementia On World Alzheimers Day ...

Research suggests that a host of factors beyond genetics may play a role in the development and course of Alzheimer’s disease. There is a great deal of interest, for example, in the relationship between cognitive decline and vascular conditions such as heart disease, stroke, and high blood pressure, as well as metabolic conditions such as diabetes and obesity. Ongoing research will help us understand whether and how reducing risk factors for these conditions may also reduce the risk of Alzheimer’s.

A nutritious diet, physical activity, social engagement, sleep, and mentally stimulating pursuits have all been associated with helping people stay healthy as they age. These factors might also help reduce the risk of cognitive decline and Alzheimer’s disease. Clinical trials are testing some of these possibilities.

Early-life factors may also play a role. For example, studies have linked higher levels of education with a decreased risk of dementia. There are also differences in dementia risk among racial groups and sexesall of which are being studied to better understand the causes of Alzheimers disease and to develop effective treatments and preventions for all people.

Loss Of Neural Circuits And Brain Plasticity

refers to the brain’s ability to change structure and function. This ties into the common phrase, “if you don’t use it, you lose it,” which is another way of saying, if you don’t use it, your brain will devote less somatotopic space for it. One proposed mechanism for the observed age-related plasticity deficits in animals is the result of age-induced alterations in calcium regulation. The changes in our abilities to handle calcium will ultimately influence neuronal firing and the ability to propagate , which in turn would affect the ability of the brain to alter its structure or function . Due to the complexity of the brain, with all of its structures and functions, it is logical to assume that some areas would be more vulnerable to aging than others. Two circuits worth mentioning here are the and neocortical circuits. It has been suggested that age-related cognitive decline is due in part not to neuronal death but to synaptic alterations. Evidence in support of this idea from animal work has also suggested that this cognitive deficit is due to functional and factors such as changes in enzymatic activity, chemical messengers, or gene expression in cortical circuits.

Life Expectancy After An Alzheimers Disease Diagnosis

  • Expert Advice

Learn about the many factors that affect average life expectancy after a diagnosis of Alzheimers disease.

Genevieve* asked if she could speak privately with me after her mothers evaluation session and diagnosis of Alzheimers disease. I didnt want to ask this in front of her, she said, but my brother and I want to knowhow much time does she have left? Life expectancy after a diagnosis of Alzheimers disease, while uncomfortable to discuss, can be important information for patients and families to have. Ill describe what we know about this topic, and some of the factors that affect survival with and without dementia. Please bear in mind that this information is based on statistical averages, and there can be individual variations in the disease and a person’s resilience to it.

*The name and details were changed to protect privacy.

The most honest answer to Genevieves question may be, It depends. After a diagnosis of Alzheimers disease or another dementia, people can live for months to years, depending on individual circumstances. Its been shown that factors like age, race, genetics, health background, socioeconomic status, and education influence the life expectancy of large numbers of people with Alzheimers. However, every individuals disease is different, and may not follow the average course.

How Does Alzheimers Impact Life Expectancy

According to a study, the key factors that determine how long someone lives after being diagnosed with Alzheimer’s disease and other forms of dementia are gender, age, and level of disability:

  • While men lived approximately 4.1 years following diagnosis, women lived approximately 4.6 years.
  • When someone who is over the age of 90 is diagnosed with Alzheimer’s disease, they live 3.8 years. In contrast, someone under the age of 70 lived 10.7 years.
  • If a patient was frail when they were diagnosed, they didn’t live as long even after the adjustment for age has been made.

In the end, the average survival time for those diagnosed with Alzheimer’s disease and other forms of dementia was 4.5 years.

Support For Families And Alzheimer’s Disease Caregivers

Delivering an Alzheimer’s Disease Diagnosis

Caring for a person with Alzheimers can have significant physical, emotional, and financial costs. The demands of day-to-day care, changes in family roles, and decisions about placement in a care facility can be difficult. NIA supports efforts to evaluate programs, strategies, approaches, and other research to improve the quality of care and life for those living with dementia and their caregivers.

Becoming well-informed about the disease is one important long-term strategy. Programs that teach families about the various stages of Alzheimers and about ways to deal with difficult behaviors and other caregiving challenges can help.

Good coping skills, a strong support network, and respite care are other things that may help caregivers handle the stress of caring for a loved one with Alzheimers. For example, staying physically active provides physical and emotional benefits.

Some caregivers have found that joining a support group is a critical lifeline. These support groups enable caregivers to find respite, express concerns, share experiences, get tips, and receive emotional comfort. Many organizations sponsor in-person and online support groups, including groups for people with early-stage Alzheimers and their families.

Using The Gds To Measure Dementia Progression

As the disease progresses, different signs and symptoms will become increasingly obvious. While there are several scales to measure the progression of dementia, the most common scale is the Global Deterioration Scale for Assessment of Primary Degenerative Dementia . The scale is also known as the Reisberg Scale. According to the GDS, there are seven different stages of Alzheimers disease correlating with four distinct categories: no Alzheimers, mild Alzheimers , moderate Alzheimers , and severe Alzheimers .

Stage : Preclinical Alzheimers Disease

Alzheimers disease begins long before any symptoms become apparent. An individual who is at the preclinical stage of Alzheimers disease is fully independent and may not even be aware they have the disease. They may not experience any symptoms and if they do, they will be very mild and considered to be normal everyday occurrences, especially for an older adult, such as minor memory lapses forgetting words or where things are kept, things we all forget from time to time. Even a medical examination may indicate no presence of dementia.

This stage is called preclinical because its usually identified only in a research setting. Research laboratories now have new imaging technologies able to identify the common amyloid-beta protein deposits in the brain a hallmark indicator of Alzheimers disease.

Symptoms wont be apparent to you or to those around you yet. This stage can last for many years, possibly even decades, before you notice any symptoms at all.

What Is The Burden Of Alzheimers Disease In The United States

  • Alzheimers disease is one of the top 10 leading causes of death in the United States.2
  • The 6th leading cause of death among US adults.
  • The 5th leading cause of death among adults aged 65 years or older.3

In 2020, an estimated 5.8 million Americans aged 65 years or older had Alzheimers disease.1 This number is projected to nearly triple to 14 million people by 2060.1

In 2010, the costs of treating Alzheimers disease were projected to fall between $159 and $215 billion.4 By 2040, these costs are projected to jump to between $379 and more than $500 billion annually.4

Death rates for Alzheimers disease are increasing, unlike heart disease and cancer death rates that are on the decline.5 Dementia, including Alzheimers disease, has been shown to be under-reported in death certificates and therefore the proportion of older people who die from Alzheimers may be considerably higher.6
