Creutzfeldt-Jakob Disease (CJD): An Overview of Symptoms, Causes, & Diagnosis
HTML-код
- Опубликовано: 7 окт 2024
- Creutzfeldt-Jakob Disease (CJD) is a rare and fatal neurodegenerative disorder caused by the abnormal folding of proteins, known as prions. I made an animated overview of the Symptoms, Causes, Diagnosis, Pathophysiology & management. All four types of CJD are discussed in the video.
Thank you for watching! Please let me know what you think in the comments section.

My dad is in the hospital now fighting for his life with CJD. This video helped me understand what’s happening with my dad. However, I’m broken right now seeing that there is no cure. I can’t lose my dad.
I can understand the pain u are going through
My grandma is in the process of getting a diagnosis the neurologist is pretty sure this is what she has but they need a spinal tap to confirm. It’s been 10 months and she is in such a depressing state. Breaks my heart to think this is her future
İ am in same situation like you :(
Hope youre ok
Give your pain and sadness to God. He is with you every step of the way. So is your dad.❤
My mother was just diagnosed today with CJD. She is in the final stage of this disease. Thank you for this video!
Hello. My mom has just diagnosed by 14-3-3 test was positive😢 what is the final stage? Mine can only see i think and barely open her eyes. She only has her breath and the first symptom was 2 months ago and was dementia😢 may God give peace all ppl with CJD
@@SErdm-ed6bn is she still alive?
@@SErdm-ed6bnthe final stage is sadly, death my friend. 😞
Did she take Ticovac vaccine ? The one for tick encefalites ?
@@Aqui-em-casa-e-assimvaccines cannot give you prions
Prionic diseases are the most terrifying diseases...
CJD, Kuru, and FFI, possibly others are most terrifying...
There are only three transmissable disease groups that actually scare me: prion diseases, hemorrhagic fevers, and lyssaviruses.
eh kuru isn't that scary cause you have to do cannabilism to get it so pretty avoidable
Aids , cwd , cjd , all “prions”, prions were “weaponized” long ago
@@gabrielsfilms2086 no, thats just one of the many ways it is transmitted (not the only way)
@@guysumpthin2974 im talking about JUST kuru, all the other ones are also not that scary cause its rare (assuming you don't have a family history of it) but they are still scarier than kuru
my grand pa died of this disease. He was a vegan and this video helped me understand what are the other causes
I'm sorry to hear about it. Glad you found this helpful.
Did he take other medications?
It might have been becuase he had it from genetics or his had it from a protein misfolding
Did he take any vaccine before ? Especially tick born vaccine ?
is grandpa bad?
My psychologist died from this cruel disease. So did an ex partners father. Thank you for the video.
I used to be totally terrified pf prions and their concept
but their seemingly very very rare incidence rate keeps them sequestered in the book of 'regular' curses and how they can be placed upon you
@@billybones6463 can you please explain?
How? It's 1:1000000 chance to get this disease!
@@eden8817they mean it's rare to get. Still terrifying, especially considering Mad Cow disease, could happen again. Worst way to leave this world.
This and CWD (Chronic Wasting Disease) seem to be caused by the same issue. Even a single prion misfold can cause your entire nervous system to turn on you.
Exactly. I have an educated guess that the development and spread of these prions through the brain works in an exponential growth pattern. From that first molecule misfolding, the spread of the disease prion is slow, but this rate will increase with the presence of more prions. Once there are enough prions to cause symptoms, the disease is able to progress rapidly, therefore the patient declines rapidly. The rate of progression then continues to increase. I need to do more research, but this is my guess as to how it works based on what I’ve learned so far.
@@mollymc2912I've only recently got into this whole issue and your comment is more than interesting. Would you mind telling me if you've come across any new findings?
My grandma died from this when I was 10. It was like watching dementia in hyper speed. She was in a wheelchair within only a few months, and only a few months after that she became mute. It only took about nine months for the disease to kill her, and we could only watch as she lost more and more of herself.
I hope one day we can find a solution to this awful prion problem
Hopefully
Hopefully.
I hate to be the bearer of bad news, but it’s not going to be cured. Not for at least hundreds of years. Modern civilisation is in the twilight years. Even mainstream sources are now openly discussing the “competency crisis” and the fact that as of Gen Z, the so called “Flynn effect” has gone into reverse and IQ scores are now declining relative to prior generations. Once the boomers and gen x-ers die off, even currently treatable diseases will see massive rises in fatality rates.
They should stop using fetal bovine serum
some people have immunity to it mostly the people that were around kuru
It appears my sister has this. Can't get movement specialist appt. No sooner than late next month so technically undiagnosed. Watching her declining every week. Body and mind failing and helpless to stop it. I am mentally preparing for the worst. Heartbreaking. 😢Anyone else going thru this at this moment your not alone. I feel this too. Be strong. Update: September 7,2024. My sister passed May 9th after less than a week in hospital after diagnosis of almost assured CJD. Brain was donated to research and results recently came back as confirmed Sporadic CJD. I "miss" her.
Did she get diagnosed?
@@beachchaos1863 Thank you for asking. She eventually did and passed not long afterwards. Some results took longer but confirmed the diagnosis of CJD. We donated her brain to CJD research as her gift towards helping to find treatment oneday for this cruel disease.
@@beachchaos1863it's very rare, one of the rarest types of dementia. It's probably Alzheimer or another dementia
Highly dought she has the disease. The disease is so rare, since 1990 there has been 350 cases and 0 new cases so far in 2024
I don't know why I got so attached to the fictional character that is Anthony, but I felt really sad for him.
You’re an empath. Research and guard your gift carefully.
My close aunt sadly passed away from CJD. It was shocking to see how quickly it progressed and how quickly it debilitated her. After her passing, we got a call from the Ministry of Health stating that we had absolutely no choice but to cremate her, which neither we nor most importantly my late aunt wanted. After a lot of begging, they finally gave us the option to bury her as long as she was bolted into a certain metal box that they were going to bring and place her in following the funeral that was instructed to be completed the very next day. It was extremely difficult to plan and negotiate all this in literally an hour of her passing. She's definitely missed 😢
Knew someone who died from this. He had arm weakness so he initially thought it was a stroke. But further testing confirmed it was CJD.
He was gone within a month.
RIP Jeff.
One month???? Dang thats quick.
My mom passed away from this disease last year December 3-4 she was only 54 and she passed younger then my GMA I miss her a lot we need to study this more and prevent it from taking our loved ones away
My dad was diagnoised with CJB on Nov 8th last year and he passed away on Feb 1st this year. Just 60 days and he was done. Miss him a lot. he was travelling to US to visit my brorther. He was all fine before boarding flight and that was the last conversation we had. 30 minutes before his landing in Chicago , he lost his memories and he doesn't even remember i existed.
❤❤
Wtf thats brutal
Does it run in the family?
@@onefromfuture6913 no , first time
rip
I like that "subjected to an mri" having had one, i can say its very apt!
I see great potential here! Great video. A Kurzgesagt style of video and animation, clear and concise narration, good vulgarization.
I would have liked to see extra sources, though! CJD is still a very nebulous topic, and medical opinions on specifics differ. Multiple sources and confronting these oppositions in a short and synthesized manner would greatly improve this.
Very educational and enjoyable video. Keep them coming!
My mother Kim Lockrey just passed away in Petrolia Ontario Canada on Monday September 04th 2023, we just got word from the special autopsy team that this is what she died of 😢
This is two people in my life time that I've watched fade away in The most brutal way, my mom's ex husband's brother Adam Cataldo died of this when I was like 10 or 11.
man I’m so sorry for your loss :(
yes i can agree that it’s the most brutal way to pass
don’t worry bro, you can just remember that your mama and his brother are watchin’ ya in heaven
Excellent video. Could you do Lewey Body dementia? My cousin has this and parkingsons. So heartbreaking.
Thank you Deci! I'm sorry about your cousin. Will make a video about it. Thank you for the suggestion.
🙏🙏🙏
Being in the UK we got to learn quite a bit about vCJD after BSE jumped the spiecse barrier.
And apparently about one in every two thousand British people are carriers of the abnormal prions from the beef scandal to this day. And that was found out from appendicitis surgery.
Really amazing video!
It will help the Medical students more than thousands time read.
Even though Anthony is not real, watching him suffer from CJD almost made me cry. I wish he is the best he can be living in heaven
Anthony reminds us of the stages of the terrible journey that our loved ones went thru and still haunt our memories and emotions.
But that doctor is pleased with it the whole time!
I have a family friend who had a strange case recently. He woke up one morning and couldn’t feel half of his body, normally a sign of a severe stroke, but it ended up not being a stroke.
He was hospitalized and shortly after fell into a Coma, since then he’s undergone every test you could possibly imagine, seen specialists, ect and for the life of them they could not figure out what was going on he came out of his coma for a bit but lost his ability to speak and walk,and shortly after fell back into a Coma.
Finally, doctors came to a conclusion that he had spongiform encephalopathy and was going to die very soon. As far as I am aware he is still on Life Support to allow his direct family to see him before he goes.
What an absolutely brutal disease.
ik how u feel i lost mu twin sis to this but she had fatal sporadic insomnia where the prion attack the thalamus
hi, how old was your sister? how long she was sick
"If you enjoy this video,..." 💀

I died from cjd ....
Sorry for your los man
Liar. CJD doesn't exist.
@@marcika 👈🤡
I'm so sorry. Such an awful illness.
Moja mama je umrla od ove uzasne bolesti. Bila je potpuno zdrava uvek, umrla je sa 67.godina nakon tačno mesec dana od dijagnostikovanja ove bolesti. Oslepela je 10dana u bolnici, bila je u pelenama. Bolest je stravicna. Na kraju je bila u nekoj vrsti kome, hranu je primala kroz nos, nije bila pokretna uopste. Na kraju je umrla bas kao u ovom videu od upale pluća. Svakoj osobi koja ovo prolazi sa bliskom osobom šaljem jedan zagrljaj ❤️
Was she crying at the last stage?
I was informed by the NIHS, back in the 1980’s that some patients who received HGH from pituitary donors (like myself) were diagnosed with CJD due to contaminated storage of those glands. Unfortunately it was reported by a minute percentage of patients worldwide.
Luckily I was not in that affected lot but it probably took them several years to pin it down.
I've had so many family members pass of the familial form (23 people spanning 7 generations). I haven't done the genetic testing yet, very nervous to learn of the answers and how that will not only impact my thoughts of the future but also how it may impact my health insurance. Some of my family had huge regrets when learning they carried the mutation and their insurance dropped them. I am so sorry to hear of everyone's loss and experiences in the comments.
I wonder if preventing procreation even helps, because looks like much of it is sporadic ? There's GOTTA be a source for this.
Why would the insurance drop you?
@@onefromfuture6913 because of more of a guarantee of needing serious medical attention later in life. It's like if you're a smoker and you have higher insurance than a non smoker
@lucianaromulus1408 fawk that, what scum bags. At worst case they should increase ur premiums not leave you without insurance
Amazing video for medical students
On point video for medicos!!
Thank you dear!
My dad had a patient with this disease and they had to burn all of the equipment that came in contact with it
CJD doesn't get destroyed when coming in contact with heat. Frankly it only spreads it, therfore burning all the equitment that came in contact with CJD doesn't do anything.
@@justintian2650 fire is is over 500c hot. at fire temperatures the protens desintegrate and oxidised.
@@justintian2650 What kind of BS are you spitting? CJD can only be destroyed by denaturing the proteins with incineration that takes place above 1000 degrees celsius. Do your research jeez.
So i saw an article of a naturally occurring prion anti-body and it's found in four people and they were testing it in a lab with some other phages i hope they find a cure real soon 🔜 don't want to see anyone else suffer😢
This. Needs. More. Views.
Best explanation ever
My aunt might be diagnosed with CJD. I hope it isn’t this disease, but if the worse thing we fear, we will all do our best to let her last time here be the best.
I hope your aunt is spared from this villainous disease but should she be not you have my absolute empathy. My sister just passed from almost certain CJD yesterday and I know your journey that lays ahead of you. Give her all the love and happiness you can for the "emotional" trial ahead will heartbreaking. Be strong. I am still raw in my loss but know that someone truly understands your fears. Embrace her throughout this journey.

Prions can only be transmitted through ingestion. If you ate the brain you’d be at risk.

In 2001 my Mom is 51 years old and starts to become weird and would argue with my family. We see a neurologist who diagnose my Mom as having CJD some time in 2007. I'll give you a timeline as i fall into the 1% group who did everything possible.
2002 medical retirement and no longer driving.
2003 staying at home acting weird.
2004 arguments at home
2005 Walking but leaning forward. Able to put on a seatbelt. Ability to ride a subway with me supervising. Fly to another country. Taking medication.
2006 Walking around at night pooping and peeing on the ground. Last time she said she loved me.
2007 More aggressive. Pooping and peeing on the ground. Yelling. Walking skills are not good. Currently using dippers
2008. Same thing but more issues. By late 2008 the first seizure happened and she hit her head on the dresser. No meds for this yet as we didn't know.
2009. She's sitting in a chair as her walking skills are bad. Her ability to swallow food is lost. Multiple chocking events. Feeding tube is placed. Her weight has decreased.
2010. Transitioned from sitting in a chair all day to being in bed but the ability to sit up. Her weight picks up thanks to strictly tube feeding. More seizures are happening. Her eyes are open and she's alert.
2011 Her weight gained back but still the same issues.
2012 Mom is stable but she's showing signs of Alzheimer's as we expected from the beginning. Spent 2 months in a nursing home due to pneumonia. Goes back home
2013 Mom is stable, alert with eyes open, unable to communicate verbally, or comprehend correctly whats going on. She can still laugh and give me a kiss on my check if i ask for it.
2014 Stable but the feeding tube routinely needs to get replaced. Seizure meds need to get bumped up to a higher amount. Lab work comes out fine.
2015 stable but we start to get more of a sleepyhead state.
2016 Stable but the progress downward is showing. Her weight is picking up.
2017 same as above. But now a care giver is brought in to assist. My father has open heart surgery and doing dialysis
2018 same as above but progressively showing a lack of alertness or reacting/flinching to a light
2019 hospital visit for uti
2020 In a sleepy state more often eyes closed. Sometimes wakes up with eyes open and goes to sleep.
2021 progress downward
2022 survivors covid +. We as a family agree to not replace the feeding tube if it falls out. After we replaced it May of 2022.
2023. Sleepy state with eys closed nearly all day. I can still get her to kiss my cheek if i let her lips touch it. May I transitioned to a night shift for work 2pm to 10:30pm resulting in no help from anyone to change her diaper. Yes it was all me picking her up out of bed putting her on a bedside kamode to clean her bottom. I took extra care to ensure she couldn't touch her feeding tube.
October 2023 My dad has liver seriouses and ascites. As im changing my mom on Sunday night October 15 she starting leaning forward and the tube fell out. We agreed to not put the tube back.
October 29 my Dad throws up dark colored stuff that looks like coffee beans. He goes to the ER well aware my Mom hasn't eaten in 14 days.
October 29th 9pm Mom passes away and my Dad wasn't home. Very painful to see my Mom pass away. Despite the Alzheimer's/cjd she started crying at the end.
After 20 years of caring for my Mom I had a lot of time to think about what would happen if she's gone. Every situation in my head. I never gave the funeral or burial any thoughts. That was difficult. It cost $30,000 to bury her including the ceremony service. Stressful coming up with money needed, arrangements, life, and everything else. Hopefully this brings some help to someone.
Please make your home 911 compatible. You'll thank me later.
Definitely not CJD. Seems like Alzheimers though.

Earlier I used to think that prion disease only occurs when cannabilism is practised or someone eats prion infected meat
00:32 🧠 Creutzfeldt-Jakob Disease (CJD) is a rare neurodegenerative disorder characterized by rapidly progressive dementia, myoclonus, and ataxia.
01:28 🧪 Prions, misfolded proteins, play a central role in CJD. They self-replicate and convert normal proteins into abnormal ones, leading to cell death and disease progression.
02:27 📊 CJD can be sporadic, familial, iatrogenic, or variant, with different causes and risk factors. Variant CJD is associated with Mad Cow Disease and can be transmitted through contaminated food.
03:52 🩺 Diagnosis of CJD involves EEG, MRI scans, lumbar puncture, and the detection of specific proteins in cerebrospinal fluid. Brain biopsies are rarely performed in living patients.
04:49 💊 Unfortunately, there is no cure for CJD, and most patients with the disease die within a year of symptom onset. Autopsy confirms the diagnosis after death.

Wait what about not being mobile gives you pneumonia???
Well, if you don't move you take more shallow breaths for a long term. That means that mucus isn't cleared that easily from the lungs and that increases the risk of infections. Coughing while lying is also difficult.
Fantastic video! Odd question from a layperson, but could it be argued that Alzheimer’s Dementia could be considered a prional disease because of the self-replicating behaviours of Amyloid Beta and Tau Protein, or is the prional classification specific to malformed PrP variants?
And an additional question, if you’ll indulge me- do you consider “Kuru” a separate illness from CJD? I don’t see any real valid reason to do so, but I’d love to hear your thoughts.
I'm not the video creator but I believe a disease has to be specifically caused by malformed PrP to be considered a prion disease, otherwise it's just a disease caused by protein misfolding (e.g. Alzheimer's).
@@simplyharkonnen I did research on this topic around a year ago and wrote a paper for my college publication. Your argument for Kuru being similar to CJD has weight. The Kuru prions PRPsc are the same as the ones in CJD, however this is different from vCJD. As for Alzheimers, while we do have promising data to consider it a prional disease, we can not confidently declare prions as the causative agent for it just yet. More research is being done as we speak on relating prions with alzhemiers, lewy body dementia, parkinson's disease, and some other neurodegenerative disorders.
Most forms of neurodegenerative disease are in a way prion diseases. They just have a slower progression and low transmissibility. Still, they have been transmitted by extreme methods, like intracerebral inoculation of test animals. Researchers on this field is slow, and I believe that the implications are too severe and funding is restricted due this. Kuru is a traditional term for CJD and it is believed to have started from a single case of sporadic CJD.
kuru has different clinical presentation to classical cjd i believe. also misfolding protein =/ prion disease. prion disease involves the specific prion protein.@@stefanostokatlidis4861
why are prions so difficult to "kill"? I read its because its stable but what makes them stable? Also i really wonder how spontaneous cjd can just form from no where? And how does eating it make it end up in your brain?
our cells actually capable to deal with misfolding protein like prion even if they are pretty stable, so yes our cells capable to destroy prions, but reason why it isnt is multifactor, mostly its because our cells doesnt recognize this harmfull protein as a threat or our immune system not responsive to it, immune cells usually not respon or triggered to many type of neuronal proteins like tau protein, etc, but theres still atempt and onging research to cure it
This one as example and it sound promising
ruclips.net/video/yEnK9Ag2Xaw/видео.htmlsi=Z-yHOYOMitkQPa43
I am by no means an expert but I believe it's their geometric shape, the same thing that makes spider silk stronger than kevlar, despite also being just a mesh of proteins. Prions have a unique 3d shape which makes them exceptionally durable and stable.
The PrP protein has two forms, the regular non-pathogenic one is the form that the body manufactures. But unfortunately, it isn't the most stable one (lowest energy state). It has a second, more stable form which it can acquire spontaneously, the prion.
My interpretation of why this happens is because the process of manufacturing proteins by the ribosomes isn't perfect and generates defective, misfolded proteins all the time, and due to probability it only takes one off chance for them to misfold a prion into existence while creating a PrP protein. What makes it stand out from other defective proteins is that it's stability allows it survive the enzymes that the cells use to dispose of such proteins.
How it "infects" other PrP proteins is mostly speculation. But, the key thing to remember is that prions only convert/misfold other PrP proteins, which is why I believe it's again due to their stability, prions can somehow incite them into also acquiring the lowest energy state like themselves, because everything "wants" to be in it's lowest energy state. This is kinda similar to strange matter.
Notice the use of the word "fold" so far, this is important because in proteins, the way they are folded determines their functions. If they aren't folded correctly, it may hinder their ability to function or make them harmful to the cell. Sickle cell disease is also caused by a misfolded hemoglobin protein that binds together in large chunks, deforming the cell. Misfolded PrP protein has similar origins but its abilities to convert other PrP proteins and immunity to enzymes makes it very dangerous.
When ingested, stomach acids fail to break down prion back into amino acid due to their durability. After this, prions just linger within a person's circulatory system, as PrP proteins are mostly found within the brain and the nervous system, floating freely without much to infect. It's once they breach the blood-brain barrier that they begin to cause a lot of harm all at once, this is possible because of their small size, as individual prion proteins tend to be smaller than even viruses. In the brain, they misfold regular PrP proteins and form large aggregates that disrupt essential functions and trigger an immune response which isn't able to achieve anything and merely cause more harm.
The only enzyme that I know of that can destroy prions is keratinase, from a bacteria. Humans and other animals got nothing to get rid of the aggregates and can just wait for death at that point.
@@wagoni3505can this keratinase pass bbb?
well the prions go into ur bloodstream when u eat it and it reaches ur brain. idk if I'm right or wrong, this is just what I heard
i assume they rarely are deformed when they are formed kind of like a cancer

I had watched another video on the topic of fasting, they claimed that after three days of not eating food, your body will begin to eat the improperly folded proteins in your body that are cancerous or may cause it.
