Rapidly Progressive Dementia: From Prions to Antibodies

Theres no cure for dementia, but there are ways for seniors to reduce their risk of developing this condition or slow its progression. Seniors should follow a healthy diet, exercise regularly, socialize, manage stress, and avoid head injuries. They should also participate in mental activities that boost their cognitive health and slow down the aging process.

Caring for a loved one with dementia can sometimes feel overwhelming, but help is available. Seniors can face a variety of age-related challenges. Though some families choose to take on the caregiving duties, there may come a time when they need a trusted Clearwater homecare services provider. Families sometimes need respite from their duties so they can focus on their other responsibilities, and some seniors need around-the-clock assistance that their families are not able to provide.

How Does Rpd Differ From Other Types Of Dementia

Dementia, especially of Alzheimers type, typically develops slowly over many years and is often diagnosed in the late stages of the illness. RPD, on the other hand, is different as it progresses much more quickly. However, compared to Alzheimers disease and vascular dementia, RPD tends to be rare, often challenging to diagnose, and can develop at a greater rate.

The course of RPD is variable and depends on the cause. For example, the average age of onset of sporadic Creutzfeldt-Jakob disease is 6070 years. Those affected may initially experience fatigue, sleep disturbances, and decreased appetite, all of which may occur weeks before the onset of nervous system dysfunction. Behavioural changes can also be an early sign of disease.

As shown below, a number of conditions in addition to CJD can cause RPD and functionally impair a person at a faster rate than other forms of dementia.

Neurodegenerative And Vascular Dementias

Rapidly progressive Alzheimer disease

Studies on prion disease diagnosis and RPD have revealed AD as a major differential diagnosis,,. The heterogeneity of AD is increasingly recognized, and diagnostic standards have yet to be defined for atypical forms of AD characterized by rapid disease progression, a poor prognosis, a distinct clinical and neuropsychological syndrome and possibly a specific genetic background. Most such cases were discovered within the framework of clinical surveillance centres for prion diseases,,. The patients exhibited a very rapid disease course with dementia and various early focal neurological signs and symptoms, and they died within 24 months of disease onset.

Rapidly progressive types and subtypes of other neurodegenerative dementias

Cases of RPD have also been described among individuals with -synucleinopathies, in particular, dementia with Lewy bodies . The mean disease duration of DLB is more than 8 years, but advanced age at onset, Lewy body disease of the diffuse type and alterations in markers of the innate immune system, were found to be associated with substantially shorter survival times. However, no distinct neuropathological subtype of rapidly progressive DLB has been identified to date. Other factors that might give a clinical impression of RPD or lead to a shortened survival time include the characteristic symptom fluctuations, recurrent falls and frequent occurrence of delirium in DLB.

Rapidly Progressive Dementia

Dementia is a progressive impairment of cognitive function caused by damage to the brain. Over time, a person with dementia will have increased difficulty with memory, understanding, communication, and reasoning.

Healthcare providers frequently speak about a persons dementia in terms of stages. This can be helpful for communicating with family or other healthcare providers regarding the persons illness, and it is important for determining an appropriate care plan.

How Fast Does Dementia Progress?

It is important to note that dementia progresses at different speeds for every person, and for different types of dementia. The most well-known form of dementia, Alzheimers disease, is just one specific type of dementia, and tends to have the slowest progression of all types. Some factors that affect the rate of progression include:

  • Age
  • Repeated infections

What are the Stages of Dementia?

There are a few different systems used to grade dementia — at the most basic there is early, moderate, and end. Many providers use the system developed by Dr. Barry Reisberg of New York University which includes 7 stages. The Reisberg scale is also known as the GDS or Global Deterioration Scale for Assessment of Primary Degenerative Dementia. This scale focuses primarily on cognitive abilities.

Frontotemporal Dementia: Early Symptoms Vary

In contrast to Alzheimers, people at the early stages of frontotemporal disorders generally dont have trouble with short-term memory. But depending on the type of frontotemporal issue, early symptoms may vary.

For the type of frontotemporal disorder that initially affects the part of the brain that controls behavior, people may behave rudely or appear oblivious to social norms, seem easily distracted, or appear uncharacteristically selfish or unfeeling.

For the less-common type of frontotemporal disorder that initially affects the part of the brain that controls language skills, the early stage includes trouble attaching names to things, comprehending words, or speaking fluently.

But as dementia becomes progressively worse, people who are experiencing behavior changes will begin having language difficulty, and vice versa.

As frontotemporal disorders progress, symptoms will begin to resemble those of Alzheimers, though agitation and aggression generally develop before short-term memory loss and other symptoms of later-stage Alzheimers, such as trouble judging distance and difficulty seeing objects in three dimensions.

On average people with frontotemporal disorders live for six to eight years after the onset of symptoms.

Stage : Moderately Severe Dementia

When the patient begins to forget the names of their children, spouse, or primary caregivers, they are most likely entering stage 6 of dementia and will need full time care. In the sixth stage, patients are generally unaware of their surroundings, cannot recall recent events, and have skewed memories of their personal past. Caregivers and loved ones should watch for:

  • Delusional behavior

Initial Causes What Type Of Dementia Progresses Rapidly

What Are Rapidly Progressive Dementias? | LiveTalk | Being Patient

There are several different causes of memory loss. Some cause this condition in the young, while others may be more gradual. If you notice that your memory is weakening, its important to consult a medical professional. Whether the cause is mental illness, age, or a combination of factors, its important to seek treatment as soon as possible. People with extensive memory loss may have social difficulties and anxiety, which can lead to depression. They may be afraid they are letting their loved ones down, which can lead to anxiety and depression. What Type of Dementia Progresses Rapidly

Fortunately, there are many causes of memory loss, and many of them are treatable. However, if you are experiencing serious memory problems, you may need medical treatment. If you have been undergoing any type of medication, you should consult with your doctor. Some people have other underlying conditions that may be causing their loss of memory. Alcohol abuse, sleep deprivation, or other mental health conditions can cause memory problems. You should seek out a medical professional if you suspect youre suffering from any of these conditions.

What Medications Are Available To Treat Dementia

Drugs approved for the most common form of dementia, Alzheimers disease, are discussed below. These drugs are also used to treat people with some of the other forms of dementia.

  • cholinesterase inhibitors
  • NMDA receptor antagonist memantine

These two classes of drugs affect different chemical processes in the brain. Both classes have been shown to provide some benefit in improving or stabilizing memory function in some patients. Although none of these drugs appear to stop the progression of the underlying disease, they may slow it down.

If other medical conditions are causing dementia or co-exist with dementia, the appropriate drugs used to treat those specific conditions are prescribed.

Definition And Prevalence Of Rpd

One of the earliest scientific articles to mention RPD, published in the 1950s, described this disorder in the context of demyelinating diseases. In the intervening years, RPD has become increasingly recognized as a distinct clinical syndrome that occurs in atypical dementias, human prion diseases and related disorders that are considered in the differential diagnosis of these conditions,. Although general definitions usually consider less than 1 or 2 years as the time span from the first disease-related symptom to development of the dementia syndrome, some causes of RPD, such as encephalitis or metabolic encephalopathies, can lead to dementia within weeks. In addition, particular definitions of RPD in neurodegenerative diseases have been proposed, using either total disease duration or measures for speed of cognitive decline such as changes in Mini-Mental State Examination scores in rapidly progressive AD ,. A summary of common definitions,,,,,,, can be found in Table . Owing to these heterogeneous definitions, the overall incidence of RPD is difficult to determine or even to estimate, and data are scarce. According to a Brazilian study from a tertiary care centre, 3.7% of all patients referred to a neurological unit over 3 years were diagnosed with RPD. In other single-centre studies, around one-quarter of hospitalized patients with dementia were classified as RPD .

What Happens In Rpd

The progression of RPD varies from patient to patient and in part depends on the underlying cause. Patients typically develop problems with their thinking, mood/personality/behavior, ability to speak or understand, or ability to control their movements. Many are often treatable and reversible if diagnosed quickly. For some other RPDs, there are no cures, and the progression of symptoms is inevitable. There may be some treatment to help relieve specific symptoms. Patients with non-curable forms of RPD may die within months or a few years from onset.

Could It Be Rapidly Progressive Dementia

RPD can be difficult to diagnose. However, accurately diagnosing these conditions is critical in order to identify any treatable causes and protect against further brain cell damage. An early hospital assessment by a specialist can help pick up problems so that, where available, appropriate treatment can be initiated. Cancers, infections, toxins and autoimmune conditions could all cause a fast decline in mental function, as well as the more common neurodegenerative causes of dementia such as Alzheimers, strokes and Parkinsons disease.

How Does Alzheimers Impact Life Expectancy

According to a study, the key factors that determine how long someone lives after being diagnosed with Alzheimers 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 Alzheimers 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 didnt live as long even after the adjustment for age has been made.

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

How Quickly Does Dementia Progress

Slowing down the progression of dementia

For many people with dementia, progression can happen over a number of years the average falls between 4 and 10 years, but some live with the condition for 20+ years. For others, it may happen a lot faster. Things such as genetics, or previous health and medical history may play a part in how quickly dementia progresses, however the type of dementia can make a difference too.

Rapidly Progressive Dementia Tests

Ancillary testing is crucial mainly because many RPDs have similar clinical features.

Doctors may request various laboratory tests that may include:

  • Urine tests
  • Brain imaging like electroencephalogram which measures electrical activity in the brain from the scalp, MRI or CT.
  • Cerebrospinal fluid tests which involves looking at the clear fluid that surrounds the spinal cord and the brain.

The results that the doctor will gather from the tests can HELP to determine the cause of the disease.

How Is Frontotemporal Dementia Treated

Currently, no treatments are available to cure or slow the progression of FTD, but healthcare providers may prescribe medicine to treat symptoms. Antidepressants may help treat anxiety and control obsessive-compulsive behaviors and other symptoms. Prescription sleeping aids can help ease insomnia and other sleep disturbances. Antipsychotic medicine may reduce irrational and compulsive behaviors.

Behavior modification may help control unacceptable or risky behaviors.

Speech and language pathologists and physical and occupational therapists can help adjustment to some of the changes caused by FTD.

Paraneoplastic And Autoimmune Encephalopathies

If medical practitioners suspect autoimmune encephalopathy, they will recommend a trial of immunotherapy for the ill person, which will help to treat RPD in responsive persons.

Immunotherapy, however, does not work when the person with dementia has infections that will become worse after immunosuppression.

Physicians also avoid steroids when lymphoma is differential because it can DELAY EFFICIENT treatment. Worth noting is that steroid trials work as diagnostic tests as well as treatment options.

This implies that doctors need to administer a high dosage for a clear clinical response.

The doctor will determine the number of steroids to give out because currently, there is no documentation on the minimum steroid dose that is sufficient to treat dementias that are immune-mediated.

Persons who cannot tolerate steroids will often go through PLEX or a course of IVIg.

Dementia: Symptoms, Stages, Types, &  Treatment

Find out more about the way dementia progresses, including what to expect at different stages of the condition.

All types of dementia are progressive. This means that the structure and chemistry of the brain become increasingly damaged over time.

How quickly dementia progresses depends on the individual. Each person is unique and experiences dementia in their own way. This can depend on many factors, including physical make-up, emotional resilience and the support available to them.

Viewing dementia as a series of stages can be a useful way to understand the illness, but it is important to realise that this only provides a rough guide to the progress of the condition.

How Is An Rpd Diagnosed

RPD can be difficult to diagnose, so it is often necessary to see a doctor who specializes in these conditions. The doctor might ask about the patients progression of symptoms, any similar illnesses in biological relatives or any recent possible exposures . The doctor may request some laboratory testing, such as blood, urine and cerebrospinal fluid brain imaging and/or an electroencephalogram . The information gathered by the physician and tests might help to determine the cause of disease.
