Insomnia insight #308: Sporadic fatal insomnia, dont seek truth or know its no insomnia

In view of the above caveats I have found an alternative description from the 2006 Schenkein paper :

The chief clinical features of FFI include a progressive and ferocious insomnia, waking sleep, hallucinations, autonomic disturbances suggestive of sympathetic overdrive , a rise in circulating catecholamine levels, cognitive changes , motor system deficits , and endocrine manifestations. Later cognitive changes involve a confusional state resembling dementia and, ultimately, death.

The typical duration of FFI is between 7 and 36 months, with a mean duration of 18 months. Population studies show shorter mean survival time for Met-Met patients than for Met-Val patients, . These values are of particular relevance, because our case involves a Met-Met patient who surpassed 26 months of illness.

Clinically, 4 stages of FFI have been delineated, progressing from moderately disturbing to totally disabling. Although clinical symptomatology is related to polymorphism at codon 129, most end-stage patients are noninteractive and unable to care for themselves.

Is Fatal Sporadic Insomnia A Real Thing

Sporadic fatal insomnia is a relatively recently described and rare form of prion disease. Its clinical phenotype is very similar to that of the better-known familial fatal insomnia. Early features include disturbances of sleep, which are often overlooked or regarded as minor, and fluctuating diplopia.

Signs And Symptoms Of Fatal Insomnia

Initially, a person might have mixed symptoms of daytime fatigue and sleepiness and the inability to fall asleep and stay asleep. As the disease progresses, a person will experience behavioral and personality changes, abnormal body movements, vision changes, difficulty walking and maintaining consciousness.

Horrifying Symptoms Of The Life

As the name suggests, fatal familial insomnia is a life-threatening disease, which does not have a cure yet. But, an early diagnosis of the disease can help one with symptomatic management. To know more about the symptoms and causes of fatal familial insomnia, read this article.

They say, sound sleep is a bliss. It helps you to wake up fresh, energetic and keeps your mind balanced, well activated, and controlled. But, there is a small section of people, who cannot sleep at all! And this condition is known as fatal familial insomnia , which is one of the extremely rare brain disorders which adversely affects the sleep and nervous system of that person. The deprivation of sleep gradually leads to deterioration of mental and physical functions resulting in death. It is essentially an autosomal dominant disorder which involves progressive insomnia and degeneration of an essential part of the brain, known as, thalamus, which regulates sleep.

What Are The Chances Of Getting Sporadic Fatal Insomnia

Fatal Familial Insomnia

Sporadic Creutzfeldt-Jakob disease accounts for 85% of human prion diseases whereas sporadic fatal insomnia accounts for 1% to 2%. Patients with sFI share phenotypic similarities with patients who have the genetic prion disease fatal familial insomnia7 but lack a mutation at codon 178 of the prion protein gene.

Genetic And Biochemical Analysis For 14

Blood samples were obtained from all patients as well as several healthy control family members of the sibling patients #1 and #2 and patients #3 mother. PRNP gene mutation was detected in DNA isolated from the peripheral blood leukocytes as previously detailed, . The 14-3-3 protein analysis was performed on cerebrospinal fluid samples by enzyme-linked immunosorbent assay following the manufacturers protocol as described previously.

What Is Sporadic Fatal Insomnia

Scientists believe that sporadic fatal insomnia is a mutation a single gene for a single protein is miscoded to form a prion. A disease with same symptoms, fatal familial insomnia, involves a mutation in a gene called PrP. This gene makes one of the proteins that help the body regulate the use of copper. The proteins made in sporadic fatal insomnia are the same as those made in familial fatal insomnia, but researchers have not been able to track down the exact source of the condition.

Changes in the production causes changes in the way the neurons in the brain are stimulated by calcium. Eventually, neurons are stimulated all the time and “burn out.”

Sporadic fatal insomnia is very rare. Only eight people in the entire world have had this disease. It cannot be diagnosed by magnetic resonance imaging or electroencephalography . A definitive diagnosis is only possible after death through autopsy.

Is There A Cure For Fatal Familial Insomnia

Unfortunately, there is currently no known cure for FFI or any course of treatment that may slow down the diseases progression.

Not exactly great news.

The main source of treatments for FFI concentrate on trying to effectively manage the symptoms. This may include certain sleep medications, although these are seen as only a temporary fix, and they definitely wont work in the long-term.

Researchers to this day are looking into various preventive measures and effective treatments.

A study conducted on animals in 2016 suggested that immunotherapy could help to treat FFI, but further studies, including on humans, are definitely needed.

There is currently an ongoing human study, which started in March 2015. The 10 participants in the study, aged between 42 and 52 years old are all at a genetic risk of developing fatal familial insomnia. They were specifically recruited because they fall into the risk age.

They have agreed to be treated with the antibiotic, doxycycline, over a period of 10 years.The studys researchers believe that this may be an effective way to prevent the onset of FFI in those who carry the genetic mutation that causes the condition.

Id also like to highlight another rather interesting attempt at curing FFI.

EEG and brain magnetic resonance imaging were performed for all five patients. In addition, Patient 1 underwent brain single photon emission computed tomography to detect blood flow perfusion and magnetic resonance spectrum . Patient 2 underwent a FDG positron emission tomography scan to illustrate the glucose metabolism of brain.

Fatal Familial Insomnia Symptoms And Stages

Prion diseases share a handful of common symptoms, including fatigue and lethargy, cognitive decline , hallucinations, rigidity , and changes in ability to walk and talk. But just as not all prion diseases are contracted in the same way, not all prion diseases have the same symptoms.

Insomnia is the early red flag, the hallmark of FFI, but sleep cycle disturbances aren’t the only problem those afflicted with the disease experience. It moves through four distinct stages as it progresses. The first symptoms of FFI usually strike when a person is middle-aged, about 48 years old , and the disease progresses rapidly. While some who develop FFI may live for two to three years, others may die within a year.

The first stage of the disease begins with insomnia, which typically gets worse over about a span of about four months. Some patients, however, only recognize it as a symptom something is wrong long after other problems of the disease begin to make themselves known. During these initial months FFI sufferers also begin to experience psychiatric complications, including panic attacks, paranoia and phobias . During stage one, patients also report vivid dreaming when they are able to sleep.

It’s during third stage of FFI, which is a short stage of about 90 days, when the wake-sleep cycle becomes completely disrupted and total insomnia begins.

Enhancing Healthcare Team Outcomes

Fatal familial insomnia is best managed by an interprofessional team, including sleep specialists, neurologists, psychiatrists and psychologists, social workers, palliative nurses, and hospice care. This disorder has no cure and is managed by first making the patient comfortable and improving the quality of life. Hospice should be involved early in the care. Psychosocial counseling for family members is necessary as well.

Fatal Familial Insomnia: Symptoms And Diagnosis

Unlike other prion diseases that can affect various regions of the brain, fatal familial insomnia and sporadic fatal insomnia primarily affect one part of the brainthe thalamus. This is the part of the brain that helps control your sleep/wake cycles. These conditions damage the thalamus to the point at which the brain remains in a state of wakefulness.

Symptoms often develop gradually. You may have increasing difficulty falling or staying asleep. You may twitch or kick involuntarily while you sleep. Eventually, sleep becomes impossible.

As you know, sufficient sleep is vital for the health of your brain and the rest of your body. Its necessary for the memory and cognitive functions of the brain to operate normally. Sleep also plays an important role in energy conservation and the regulation of hormones and our metabolism.

The physical and psychological symptoms of fatal familial insomnia and sporadic fatal insomnia include panic attacks and hallucinations, an accelerated heart rate, excessive sweating, and wild mood swings. As the diseases advance, weight loss and dementia occur. A patient with fatal insomnia may become mute toward the end of his life.

Death may come within a year of symptoms developing or it may take up to five or six years, depending on how quickly the disease progresses. Usually, fatal familial insomnia and sporadic fatal insomnia develop in adulthood, between the ages of 30 and 50.

Fatal Familial Insomnia Is A Prion Disease

Angelman Syndrome Insomnia

Fatal familial insomnia is a prion disease.

Sometimes prion diseases are called transmissible spongiform encephalopathies because some of them are contagious, but fatal familial insomnia is not contagious.

A prion is a protein called PrPc, and its function is not known. When it is folded in an abnormal shape, as in fatal familial insomnia, it is called PrPSc. These abnormal prions build up in several areas of the brain, and their presence is toxic, causing damage. Experts say that the toxic proteins may build up over years, and then suddenly cause symptoms when the brains functions are severely impaired.

What If I Have Fatal Familial Insomnia Or Sporadic Fatal Insomnia

If you’ve trekked through Google in search of answers for chronic insomnia, you’ve probably felt the fear of having Fatal Familial Insomnia or Sporadic Fatal Insomnia .

These are extremely rare, hereditary diseases. Fatal Familial Insomnia affects about 1 out of every million people and there are only around 30 documented cases of Sporadic Familial Insomnia in existence.

What separates these diseases from insomnia is that with FFI and SFI, there is no fear or worry about sleep. Insomnia is the struggle to sleep however, with neurodegenerative disorders like FFI/ SFI, there is no struggle or wonder about whats causing sleeplessness.

If you are worried and anxious about sleep, this is an indication that you do not have FFI/SFI.

Its unfortunate that these conditions use the word ‘insomnia’ in their label because they really arent insomnia’s. Insomnia occurs as a result of fear and worry which ultimately leads to hyperarousal in the brain. With FFI and SFI, there is no fear or anxiety about sleep.

If you have FFI/SFI anxiety, please know you are not alone. Its a very common concern for people experiencing insomnia, I thought I had it for years.

Accumulation Of Prion Protein

Fatal insomnia is considered a prion disease, and thus also involves the accumulation of abnormally-folded forms of prion protein in the brain. These misfolded proteins have a tendency to accumulate into clusters that are resistant to being broken down by brain enzymes. The implications of these protein clusters forming in the brain is unclear, although they are often linked to pathological changes in the brain.

Prion proteins also are capable of passing their misfolded state on to other healthy proteins. Thus, they can spread within the brain of an infected patient, gradually increasing the number of misfolded prion proteins. Interestingly, their “infectious” quality also allows prions to cause disease if transmitted from one host to another. While it isn’t thought that fatal insomnia is spread among people in this way, the disease has been transmitted to mice by injecting them with a liquefied piece of brain tissue from a human patient who had the disease.

In fatal insomnia, however, there are relatively few clusters of prion protein in the brain as compared to other prion diseases. And, while deposits in some areas of the brain increase in number as the disease progresses, this isn’t true for the areas that experience the most neurodegeneration—like the thalamus. Thus, it’s still unclear what exactly causes the neurodegeneration that produces the symptoms of fatal insomnia.

Do I Have Fatal Familial Insomnia

For a doctor to diagnose you with fatal familial insomnia or the genetic variant, you need to undergo a sleep study and possibly have a PET scan. The scan will be able to indicate if your thalamus is underactive. During the sleep study, doctors will examine your brain activity during sleep . They can also measure what is happening in your brain while you are struggling to fall asleep. A sleep study will also be able to show if there are other possible causes of your insomnia, such as sleep apnea.

Is This The Most Famous Case Of Fatal Familial Insomnia

Fatal Insomnia – Diary 11 – No more sleep

Lets take a step back in time to the early-1980s.

A man simply known as Silvano was on board a cruise ship and was enjoying himself on the ships dance floor one evening.

This suave and elegant looking Italian gentleman was suddenly overcome with embarrassment as he noticed that his shirt had become drenched in sweat.

Silvano became extremely concerned and had to immediately check something. As he stared at his own reflection in a mirror he was greeted by two tiny black pin pricks that were his pupils.

He instantly recognized the familiar glassy-eyed stare that had accounted for his father and two sisters. He knew that this was just the beginning of this mysterious illness that had claimed so many members of his family.

Silvano knew what was to come the total abandonment of sleep, terrifying hallucinations, the tremors, the constipation, the impotence, the loss of mind and speech, and finally of course death.

Eventually Silvano referred himself to the University of Bologna. He knew they had a famous sleep unit, and he had to attend for further study into his familys fatal condition. Even though he already knew his own destiny, he wanted to do something for the current and future generations of his family.

Pietro Cortelli, one of Silvanos Doctors, was astounded when Silvano first told him, Ill stop sleeping, and within a matter of months, Ill be dead,

All his ancestors had perished in exactly the same way.

Those are not odds that youre likely to ignore.

What Are The Symptoms Of Ffi

It can take years before you start to experience any symptoms, which might begin with mild insomnia, which becomes worse over time.

If you have FFI, your body will struggle to prepare for sleep. Instead of your heart rate lowering before going to bed, it will stay elevated. You will not produce enough melatonin to promote quality sleep, and cortisol levels will also remain high, which can make you wake up and feel alert.

The lack of sleep can cause the deterioration of the mind and body and can trigger other symptoms, such as:

  • Sweating randomly and excessively
  • Unexplained weight loss and a loss of appetite
  • Difficulty regulating body temperature
  • Struggling to focus and think
  • Having speech problems
  • Getting muscle spasms while sleeping
  • Problems with your vision
  • Vivid dreams

Over time, you might only manage to get in a couple of hours of sleep a night or struggle to sleep at all. Your body will not be able to perform functions that are necessary during sleep, such as producing the human growth hormone and processing information in the brain. When your symptoms become severe, you can slip into a coma and pass away.

Daniels Response Was To Buy A Motorhome And Travel Across The Us

In a conversation a few years later, he started to sound confused and vague. At some point, he said pardon me if I sound incoherent but I havent slept for five days, says Schenkein. Medical tests revealed he was carrying the FFI mutation. Worse still, it was the form that should progress most rapidly.

Rather than crumbling into despair, his response was to buy a motorhome and travel across the US. He was an adventurous spirit he wasnt just going to sit there and die, Schenkein says. As the symptoms became more extreme, he employed a driver, and then a nurse, to take over the steering wheel when he was too unwell, she says.

Brain Activity During Sleep

One way to verify the sleep disturbances occurring in fatal insomnia is to measure sleep activity over the course of a night using a technique known as polysomnography. Polysomnography measures the electrical activity in the brain along with a number of other physiological changes that occur during sleep like eye movement, muscle activity, and the electrical activity of the heart.

Polysomnography is often used to verify a case of fatal insomnia because patients may appear to spend periods of the night sleeping, as they have their eyes closed and aren’t moving. Polysomnography reveals, however, that their brain activity doesn’t resemble a pattern of normal sleep.

In a healthy person, during sleep the brain cycles from relatively light sleep into a period of deep sleep into a period a rapid eye movement sleep. A full cycle takes about 90-120 minutes and is repeated 4-6 times per night. These different stages of sleep have characteristic electrical activity that can be measured with an EEG.
