Prion protein (PrP) deposits in the form of diffuse and cored plaques occur in most gray matter areas of the brain of individuals affected by Gerstmann–Sträussler–Scheinker disease (GSS) associated with the F198S mutation in PRNP; however, the PrP deposits in the retina have not been characterized. Furthermore, a comparative analysis of PrP deposits occurring in the brain and in the retina in GSS has not been carried out. We hypothesize that the PrP aggregation and seeding properties in the brain and retina differ. The aim of this study was to analyze PrP from brains and retinas of individuals affected by GSS, all carriers of the PRNP F198S mutation from the same pedigree. Postmortem tissues from these patients were analyzed using neuropathologic and biochemical methods including Real-Time Quaking Induced Conversion assay. PrP deposits in the retina were found only in the outer plexiform layer, did not have tinctorial property of amyloid and were immunopositive using nine antibodies recognizing epitopes throughout the PrP sequence. Biochemical analysis showed that PrP_F198S in the retina is partially detergent-insoluble, is assembled in large-size aggregates, and has seeding property. In addition, the glycosylation of full-length PrP in the retina was more complex than that of control PrP. Furthermore, the homogenates of retina did not contain the 8 kDa PrP internal fragments (PrPIF) as brain homogenates do; however, a PrPIF was experimentally generated using proteinase K. In conclusion, we report for the first time the neuropathologic and biochemical properties of PrP in the retina of individuals carrying PRNP F198S and compare them with those in the brain of the same individuals. The fact that in GSS F198S, PrPIF is constitutive only in the brain points to the need of identifying whether there is a difference in proteolytic mechanisms between retina and brain.

snip…

PrP in the retina is composed of PrP aggregates with different sizes compared to brain and has lower seeding activity than PrP in the brain The PrP optical density measured on an immunoblot of fraction 1 of the retina and the brain are similar, suggesting that the amount of total PrP is similar. Since the distribution of PrP aggregates is different between the retina and the brain, we conclude that there is higher seeding activity in the brain. The biochemical results are, of course, likely related to PrP deposits in the brain and retina being composed of amyloid PrP and non-amyloid PrP, respectively, in the two distinct tissues [39]. Using RT-QuIC analysis of two subjects (D and E), we measured the seeding activity of PrP. In the retina, it was detectable down to a 10–4 dilution but was not detectable at the end-point dilution of 10–6. In contrast, brain tissue diluted down to 10–6 showed seeding activity, indicating that retina has at least 2 log10 SD50 lower seeding activity when compared to brain tissue. This difference may be explained by the lower amount of aggregated and insoluble PrP in the retina.

Clinical considerations Data obtained from the previous clinical studies of the nine GSS subjects focused on the progression of the motor and cognitive deficits. Even though patients might not have been aware of a visual deficit, it is not possible to determine whether any deficit was present at any time during the course of the disease since the neuro-ophthalmologic examination included the examination of ocular movement but did not include studies of visual acuity, visual fields, electroretinograms, and optical coherence tomography. It should be noted that as the illness progresses, such studies would not have been possible due to the progression of the movement disorder and cognitive symptoms. The description of the ex vivo pathologic changes in the CNS of multiple individuals from the same pedigree provides a stimulus for a systematic in vivo investigation of the pathophysiology of the retina. The fact that this study reports data on the changes in the late stage of disease does not exclude the possibility that the OPL might be involved early in the course of the illness. An early presence of PrP deposits has been reported in CJD patients with two month duration of disease.

In conclusion, the multidisciplinary studies carried out on brain and retina of GSS F198S have revealed important aspects of PrP aggregation in different areas of the CNS. Amyloid plaque formation is particularly high in the molecular layer of the cerebellar cortex where a large number of synapses occur between parallel fiber endings and spines of the Purkinje cells. The analysis of the retina has shown that a full-length highly glycosylated PrP, confined to the OPL, is not forming amyloid. This PrP is located in an area high in synapses related to the connection of photoreceptors with bipolar cells.

ABSTRACT

Sporadic Creutzfeldt-Jakob disease (sCJD) is the most common prion disease in humans and has been iatrogenically transmitted through corneal graft transplantation. Approximately 40% of sCJD patients develop visual or oculomotor symptoms and may seek ophthalmological consultation. Here we used the highly sensitive real-time quaking-induced conversion (RT-QuIC) assay to measure postmortem prion seeding activities in cornea, lens, ocular fluid, retina, choroid, sclera, optic nerve, and extraocular muscle in the largest series of sCJD patient eyes studied by any assay to date. We detected prion seeding activity in 100% of sCJD eyes, representing three common sCJD subtypes, with levels varying by up to 4 log-fold among individuals. The retina consistently showed the highest seed levels, which in some cases were only slightly lower than brain. Within the retina, prion deposits were detected by immunohistochemistry (IHC) in the retinal outer plexiform layer in most sCJD cases, and in some eyes the inner plexiform layer, consistent with synaptic prion deposition. Prions were not detected by IHC in any other eye region. With RT-QuIC, prion seed levels generally declined in eye tissues with increased distance from the brain, and yet all corneas had prion seeds detectable. Prion seeds were also present in the optic nerve, extraocular muscle, choroid, lens, vitreous, and sclera. Collectively, these results reveal that sCJD patients accumulate prion seeds throughout the eye, indicating the potential diagnostic utility as well as a possible biohazard. IMPORTANCE Cases of iatrogenic prion disease have been reported from corneal transplants, yet the distribution and levels of prions throughout the eye remain unknown. This study probes the occurrence, level, and distribution of prions in the eyes of patients with sporadic Creutzfeldt-Jakob disease (sCJD). We tested the largest series of prion-infected eyes reported to date using an ultrasensitive technique to establish the prion seed levels in eight regions of the eye. All 11 cases had detectable prion seeds in the eye, and in some cases, the seed levels in the retina approached those in brain. In most cases, prion deposits could also be seen by immunohistochemical staining of retinal tissue; other ocular tissues were negative. Our results have implications for estimating the risk for iatrogenic transmission of sCJD as well as for the development of antemortem diagnostic tests for prion diseases. snip… Our findings support the World Health Organization classification of eye components as having high prion infectivity and have implications for patient safety. As the early-disease phase of sCJD often includes visual symptoms (27–29), patients with sCJD will often have diagnostic assessments performed by an ophthalmologist, potentially contaminating instruments. Experimental models have shown that prions spread from brain to the retina in mice by 60% of the incubation period, prior to the onset of clinical disease (51). Although in humans it is not yet clear when prions accumulate in the eye, the finding of prion seeding activity in all sCJD eyes bolsters recommendations for single-use instruments or other decontamination procedures to prevent iatrogenic prion transmission. Cadaveric corneas have been a source of iatrogenic prion transmission, and grafts are commonly performed (35). With the increased frequency of corneal grafting worldwide, optimizing biosynthetic substitutes would be a justified research priority and is currently under development in multiple laboratories (54, 55). In all sCJD patient eyes examined, PrPSc aggregates were highly visible in the posterior retina, an accessible CNS window that could potentially be exploited for the early diagnosis of prion disease. For example, an electroretinogram is an antemortem, noninvasive diagnostic tool that may reveal early electrical abnormalities, particularly considering the prion deposits in synaptic plexi. Because other protein aggregates such as amyloid-β, α-synuclein, and tau may also spread from brain to retina, it would also be important to continue to evaluate eyes from patients having more common neurodegenerative diseases, such as Alzheimer’s disease, synucleinopathies, and tauopathies, particularly in light of recent findings showing the prion-like spread of protein aggregates through the CNS (56–59).

Eye procedure raises CJD concerns

By STEVE MITCHELL, Medical Correspondent

WASHINGTON, Nov. 18 (UPI) -- A New York man who died from a rare brain disorder similar to mad cow disease in May underwent an eye procedure prior to his death that raises concerns about the possibility of transmitting the fatal disease to others, United Press International has learned.

The development comes on the heels of the announcement Thursday by U.S. Department of Agriculture officials of a possible second case of mad cow disease in U.S. herds.

Richard Da Silva, 58, of Orange County, N.Y., died from Creutzfeldt Jakob disease, an incurable brain-wasting illness that strikes about one person per million.

Richard's wife Ann Marie Da Silva told UPI he underwent a check for the eye disease glaucoma in 2003, approximately a year before his death. The procedure involves the use of a tonometer, which contacts the cornea -- an eye tissue that can contain prions, the infectious agent thought to cause CJD.

Ann Marie's concern is that others who had the tonometer used on them could have gotten infected.

A 2003 study by British researchers suggests her concerns may be justified. A team led by J.W. Ironside from the National Creutzfeldt-Jakob Disease Surveillance Unit at the University of Edinburgh examined tonometer heads and found they can retain cornea tissue that could infect other people -- even after cleaning and decontaminating the instrument.

"Retained corneal epithelial cells, following the standard decontamination routine of tonometer prisms, may represent potential prion infectivity," the researchers wrote in the British Journal of Ophthalmology last year. "Once the infectious agent is on the cornea, it could theoretically infect the brain."

Prions, misfolded proteins thought to be the cause of mad cow, CJD and similar diseases, are notoriously difficult to destroy and are capable of withstanding most sterilization procedures.

Laura Manuelidis, an expert on these diseases and section chief of surgery in the neuropathology department at Yale University, agreed with the British researchers that tonometers represent a potential risk of passing CJD to other people.

Manuelidis told UPI she has been voicing her concern about the risks of corneas since 1977 when her own study, published in the New England Journal of Medicine, showed the eye tissue, if infected, could transmit CJD.

At the time the procedure was done on Richard Da Silva, about a year before he died, she said it was "absolutely" possible he was infectious.

The CJD Incidents Panel, a body of experts set up by the U.K. Department of Health, noted in a 2001 report that procedures involving the cornea are considered medium risk for transmitting CJD. The first two patients who have a contaminated eye instrument used on them have the highest risk of contracting the disease, the panel said.

In 1999, the U.K. Department of Health banned opticians from reusing equipment that came in contact with patients' eyes out of concern it could result in the transmission of variant CJD, the form of the disease humans can contract from consuming infected beef products.

Richard Da Silva was associated with a cluster of five other cases of CJD in southern New York that raised concerns about vCJD.

None of the cases have been determined to stem from mad cow disease, but concerns about the cattle illness in the United States could increase in light of the USDA announcement Thursday that a cow tested positive on initial tests for the disease. If confirmed, this would be the second U.S. case of the illness; the first was detected in a Washington cow last December. The USDA said the suspect animal disclosed Thursday did not enter the food chain. The USDA did not release further details about the cow, but said results from further lab tests to confirm the initial tests were expected within seven days.

Ann Marie Da Silva said she informed the New York Health Department and later the eye doctor who performed the procedure about her husband's illness and her concerns about the risk of transmitting CJD via the tonometer.

The optometrist -- whom she declined to name because she did not want to jeopardize his career -- "didn't even know what this disease was," she said.

"He said the health department never called him and I called them (the health department) back and they didn't seem concerned about it," she added. "I just kept getting angrier and angrier when I felt I was being dismissed."

She said the state health department "seems to have an attitude of don't ask, don't tell" about CJD.

"There's a stigma attached to it," she said. "Is it because they're so afraid the public will panic? I don't know, but I don't think that the answer is to push things under the rug."

New York State Department of Health spokeswoman Claire Pospisil told UPI she would look into whether the agency was concerned about the possibility of transmitting CJD via tonometers, but she had not called back prior to story publication.

Disposable tonometers are readily available and could avoid the risk of transmitting the disease, Ironside and colleagues noted in their study. Ann Marie Da Silva said she asked the optometrist whether he used disposable tonometers and "he said 'No, it's a reusable one.'"

Ironside's team also noted other ophthalmic instruments come into contact with the cornea and could represent a source of infection as they are either difficult to decontaminate or cannot withstand the harsh procedures necessary to inactivate prions. These include corneal burrs, diagnostic and therapeutic contact lenses and other coated lenses.

Terry Singletary, whose mother died from a type of CJD called Heidenhain Variant, told UPI health officials were not doing enough to prevent people from being infected by contaminated medical equipment.

"They've got to start taking this disease seriously and they simply aren't doing it," said Singletary, who is a member of CJD Watch and CJD Voice -- advocacy groups for CJD patients and their families.

U.S. Centers for Disease Control and Prevention spokeswoman Christine Pearson did not return a phone call from UPI seeking comment. The agency's Web site states the eye is one of three tissues, along with the brain and spinal cord, that are considered to have "high infectivity."

The Web site said more than 250 people worldwide have contracted CJD through contaminated surgical instruments and tissue transplants. This includes as many as four who were infected by corneal grafts. The agency noted no such cases have been reported since 1976, when sterilization procedures were instituted in healthcare facilities.

Ironside and colleagues noted in their study, however, many disinfection procedures used on optical instruments, such as tonometers, fail. They wrote their finding of cornea tissue on tonometers indicates that "no current cleaning and disinfection strategy is fully effective."

Singletary said CDC's assertion that no CJD cases from infected equipment or tissues have been detected since 1976 is misleading.

"They have absolutely no idea" whether any cases have occurred in this manner, he said, because CJD cases often aren't investigated and the agency has not required physicians nationwide report all cases of CJD.

"There's no national surveillance unit for CJD in the United States; people are dying who aren't autopsied, the CDC has no way of knowing" whether people have been infected via infected equipment or tissues, he said.

Ann Marie Da Silva said she has contacted several members of her state's congressional delegation about her concerns, including Rep. Sue Kelly, R-N.Y., and Sen. Charles Schumer, D-N.Y.

"Basically, what I want is to be a positive force in this, but I also want more of a dialogue going on with the public and the health department," she said.

Cadaver corneal transplants -- without family permission Houston, Texas channel 11 news 28 Nov 99

Repoorted by Terry S. Singeltary Sr.son of CJD victim

"It was a story about how the Lions eye bank were harvesting corneas from victims in the Morgue, without their consent. Under Texas law, this appears to be legal (remember Texas has the Veggie liable law). Even if Family says no, this appears to happen, from what the news story said.

They said the only way to prevent this, is to fill out a form, stating not to have this done. So if you don't fill out the form, they can do this. How many people don't know about the form?

This is not only disgusting and appalling, it could be highly infectious. Without proper background checking of the donors, on their physical history, checking on past dementia, and/or family history, some of these unfortunate victims, could be passing a human TSE.

Response Jill Spitler Clevelland Eye Bank:

"No, we are not stealing.........Yes, you do have such a law in the state of Texas, but not all your state Eye Banks utilize the law. The Eye Bank that you're speaking of is only one of 43 certified Eye Bank throughout the USA.

And there are measure taken per the Medical Standards of the Eye Bank Association of America, the certifying body for eye banks and per FDA regulations to address those concerns that you speak of.

I would suggest that those interested/concern with transplant contact their local agencies. The Eye Bank Association of America has a web. site . Further if anyone has problems contacting or finding out about their local organization(s), call me or e-mail me I would be glad to help. My e-mail address is jill@clevelandeyebank.org"

Terry Singeltary responds:

"Explain this to the family in Houston who went to their loved ones funeral, only to find out that the loved one that was in the casket, had their corneas removed without their permission, without the consent of the victim or it's family. They would not have known it, only for the funny look the victim had. So, they questioned, only to find out, the corneas, had in fact, been removed without consent.

I call that stealing, regardless what the law states. This type of legal grave robbing is not a logical thing to do without knowing any type of background of the victims medical past, which really will not prove anything due to the incubation period. Eye tissue being potentially a highly infective source, there are risks here.

Should they not at least know of the potential ramifications of TSE's (the person receiving the corneas)?

Should there not be some sort of screening?

Should there be some sort of moral issue here?

If this is the case, and in fact, they can come take your corneas, without your consent, then what will they start taking next, without your consent?

Lets look at a hypothetical situation:

What would happen if my Mom (DOD 12-14-97 hvCJD) would have gotten into a car wreck and died, before the symptoms of CJD appeared. Not much money, so there was no autopsy. What would have happened to that recipient of those infecting corneas?"

Comment (webmaster): Actual transmission of CJD by means of corneal transplant may or may not be rare. The incidence of infectivity in older people could be fairly high; this is not to be confused with the lower incidence of symptomatic (clinical) CJD. It is very unlikely that familial CJD would have been diagnosed in earlier generations; however, without interviewing the family even known kindreds would not be excluded.

In blood donation, a much stricter policy is followed, even though corneal transplant may be far more dangerous (being a direct link to the brain and not going through purification steps).

Since highly sensitive tests for pre-clinical CJD are now available, it would make sense to screen corneas for CJD, just as they are screened for AIDS, hepatitus, and a host of other conditions.

Stereotactic multicontact electrodes used to probe the cerebral cortex of a middle aged woman with progressive dementia were previously implicated in the accidental transmission of Creutzfeldt-Jakob disease (CJD) to two younger patients. The diagnoses of CJD have been confirmed for all three cases. More than two years after their last use in humans, after three cleanings and repeated sterilisation in ethanol and formaldehyde vapour, the electrodes were implanted in the cortex of a chimpanzee. Eighteen months later the animal became ill with CJD. This finding serves to re-emphasise the potential danger posed by reuse of instruments contaminated with the agents of spongiform encephalopathies, even after scrupulous attempts to clean them.

PitiéSalpêtrière, Paris, France.(3) National CJD Research and Surveillance Unit Centre for Clinical Brain Sciences, University of Edinburgh, UK.

Sporadic Creutzfeldt–Jakob disease (sCJD) has been documented to be accidentally transmitted by contaminated corneal transplants. To date, only one case is considered as definite, while 5 other suspect cases are classified as probable or possible. However, the specific transmission risk associated with this widely-performed transplantation procedure has never been studied.

In this study, bioassays in transgenic mice expressing the human PrP confirmed the presence of infectivity in the cornea of 2 sCJD patients. Infectivity was also detected in other ocular tissues (optic nerve, retina, vitreous body, choroid and lacrymal gland) from one of these patients.

Based on these results, we investigated the presence of infectivity in the cornea of different TSE animal models. In conventional mice (RML strain) as well as in sheep (PG127 scrapie), infectivity could only be detected in the corneas collected at the late stage of the disease incubation phase.

In parallel to these experiments, corneas collected at different stages of the incubation period in infected mice and sheep were grafted into healthy recipients.

Our results showed that corneas collected during the late asymptomatic phase or in affected animals were able to transmit TSE infectivity. Importantly, after the death of the recipients (up to 2.5 years after surgery) infectivity could still be detected in the grafted cornea.

These data confirm the potential for sCJD transmission by corneal grafts. They also provide crucial data for the assessing the TSE transmission risk associated with various other ophthalmologic procedures.

Greetings List Members,

I hate to keep kicking a madcow, but this still is very disturbing to me. Not only for the recipient of the cornea's, but as well, for the people whom would be operated on, using the same tools that were used to put those stolen cornea's in the recipient with. No history of this donor or his family (re-ffi), or anything would be known, using stolen organs and or tissue's. I just think this is not only wrong, but very dangerous to a great many other people, as this is one of the most infectious tissues of TSE's. It seems that this practice of stealing organ/tissue happens more than we think. Anyway, the family of the victim which had their cornea's stolen, are now suing. In the example I used with my Mother, if 3 months before, she would have been in a catastrophic accident (car wreck, whatever), no autopsy (for whatever reason), no family (for whatever reason), she lay in the morgue, and after 4 hours, they come steal the cornea's, lot of people could have been infected, just because of lack of medical history of donor/family. It may be hypothetical, but very real. We need to stop the spread of this disease.

kind regards, Terry S. Singeltary Sr., Bacliff, Texas USA

From the first full year of reporting CJD TSE in the US in 2000, where 90 cases of CJD was reported that year, to today, where in September 2025, the number of CJD cases reported in the last full year reporting, which would have been 2024, the number of CJD cases for 2024 was 249 cases. So, from the first full year 2000 CJD cases were 90 cases confirmed in that year, to 2024, where 2024 CJD statistics rose to 249 confirmed CJD cases in a single year. A dramatic increase in deaths, from figures that don’t seem to be dramatic. But thes figures today, they are not from “better surveillance”, that dog don’t hunt no more. They have been saying this for over 25 years, year after year, well it’s time to call it for what it is, Human Transmissible Spongiform Encephalopathy TSE Prion cases are rising, and it’s NOT because of better surveillance, or just a “happenstance of bad luck, that 85%+ of all human cases, sporadic CJD, including VPSPr, just happen spontaneously, no, it’s because of unknown environmental factors, and or iatrogenic factors, imho…terry

To the Editor: In their Research Letter, Dr Gibbons and colleagues1 reported that the annual US death rate due to Creutzfeldt-Jakob disease (CJD) has been stable since 1985. These estimates, however, are based only on reported cases, and do not include misdiagnosed or preclinical cases. It seems to me that misdiagnosis alone would drastically change these figures. An unknown number of persons with a diagnosis of Alzheimer disease in fact may have CJD, although only a small number of these patients receive the postmortem examination necessary to make this diagnosis. Furthermore, only a few states have made CJD reportable. Human and animal transmissible spongiform encephalopathies should be reportable nationwide and internationally.

RE-Monitoring the occurrence of emerging forms of Creutzfeldt-Jakob disease in the United States

Terry S. Singeltary, retired (medically)

I lost my mother to hvCJD (Heidenhain Variant CJD). I would like to comment on the CDC's attempts to monitor the occurrence of emerging forms of CJD. Asante, Collinge et al [1] have reported that BSE transmission to the 129-methionine genotype can lead to an alternate phenotype that is indistinguishable from type 2 PrPSc, the commonest sporadic CJD. However, CJD and all human TSEs are not reportable nationally. CJD and all human TSEs must be made reportable in every state and internationally. I hope that the CDC does not continue to expect us to still believe that the 85%+ of all CJD cases which are sporadic are all spontaneous, without route/source. We have many TSEs in the USA in both animal and man. CWD in deer/elk is spreading rapidly and CWD does transmit to mink, ferret, cattle, and squirrel monkey by intracerebral inoculation. With the known incubation periods in other TSEs, oral transmission studies of CWD may take much longer. Every victim/family of CJD/TSEs should be asked about route and source of this agent. To prolong this will only spread the agent and needlessly expose others. In light of the findings of Asante and Collinge et al, there should be drastic measures to safeguard the medical and surgical arena from sporadic CJDs and all human TSEs. I only ponder how many sporadic CJDs in the USA are type 2 PrPSc?

Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America

update October 2009

T. Singeltary

Bacliff, TX, USA

Background:

An update on atypical BSE and other TSE in North America. Please remember, the typical U.K. c-BSE, the atypical l-BSE (BASE), and h-BSE have all been documented in North America, along with the typical scrapie's, and atypical Nor-98 Scrapie, and to date, 2 different strains of CWD, and also TME. All these TSE in different species have been rendered and fed to food producing animals for humans and animals in North America (TSE in cats and dogs ?), and that the trading of these TSEs via animals and products via the USA and Canada has been immense over the years, decades.

Methods:

12 years independent research of available data

Results:

I propose that the current diagnostic criteria for human TSEs only enhances and helps the spreading of human TSE from the continued belief of the UKBSEnvCJD only theory in 2009. With all the science to date refuting it, to continue to validate this old myth, will only spread this TSE agent through a multitude of potential routes and sources i.e. consumption, medical i.e., surgical, blood, dental, endoscopy, optical, nutritional supplements, cosmetics etc.

Conclusion:

I would like to submit a review of past CJD surveillance in the USA, and the urgent need to make all human TSE in the USA a reportable disease, in every state, of every age group, and to make this mandatory immediately without further delay. The ramifications of not doing so will only allow this agent to spread further in the medical, dental, surgical arena's. Restricting the reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO age group, TSE knows no boundaries. I propose as with Aguzzi, Asante, Collinge, Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al and many more, that the world of TSE Transmissible Spongiform Encephalopathy is far from an exact science, but there is enough proven science to date that this myth should be put to rest once and for all, and that we move forward with a new classification for human and animal TSE that would properly identify the infected species, the source species, and then the route.

***> NOW think iatrogenic TSE PrP transmission to humans from exposure to Cervid CWD TSE PrP, what if?

all iatrogenic cjd is, is sporadic cjd, before the iatrogenic event is discovered, traced back, proven, documented, put into the academic domain, and then finally the public domain, this very seldom happens, thus problem solved, it's all sporadic cjd.

UK Jonh Collinge MRC on sporadic CJD;

“sporadic Creutzfeldt-Jakob disease (sCJD), a rapidly progressive dementia which accounts for around 1 in 5000 deaths worldwide.”

***> 2023 Professor John Collinge on tackling prion diseases <***

“The best-known human prion disease is sporadic Creutzfeldt-Jakob disease (sCJD), a rapidly progressive dementia which accounts for around 1 in 5000 deaths worldwide.”

There is accumulating evidence also for iatrogenic AD.

Understanding prion biology, and in particular how propagation of prions leads to neurodegeneration, is therefore of central research importance in medicine.
