Creutzfeldt-Jakob disease (CJD) is a rare, fast-moving, and always fatal brain disorder. It happens when a normal body protein called prion protein changes shape into a “bad” form. The bad form forces nearby normal prion proteins to copy its shape. This sets off a chain reaction of misfolding that spreads through the brain. Nerve cells get damaged and die, and the brain tissue starts to look “spongy” under a microscope. Most people get sick in later adult life, and the illness usually worsens quickly over months. The median time from symptoms to death is about 4–5 months. The disease is very rare—about 1–2 people per million each year. CDC+1
CJD is not caused by bacteria or viruses. It is caused by a misfolded protein (a “prion”). The misfolded protein spreads its shape to other normal prion proteins and gradually damages brain circuits that control thinking, balance, movement, and vision. CDC
CJD does not spread through casual contact, touching, or normal social activities. Special medical precautions are needed only for certain tissues and instruments because prions are unusually hard to destroy with standard sterilization; stronger methods are recommended for high-risk instruments. CDC
Types of CJD
Doctors group CJD by how the misfolded prions arise. The symptoms overlap, but the source is different.
Sporadic CJD (sCJD)
This is the most common type—about 85–90% of cases. It usually starts in people over 55. No clear trigger is found; a prion seems to misfold by chance and then multiplies. www2c.cdc.govnhs.ukGenetic or Familial CJD (fCJD / gCJD)
About 10–15% of cases are due to a change (mutation) in the prion protein gene (PRNP). The mutation makes the prion protein more likely to misfold. Family members can inherit the risk. NatureIatrogenic CJD (iCJD)
Very rare cases have happened after certain medical exposures in the past, such as cadaver-derived human growth hormone injections, dura mater grafts, corneal transplants, or contaminated neurosurgical instruments. Modern procedures and stronger sterilization steps have prevented equipment-linked cases since the 1970s. CDCVariant CJD (vCJD)
This type is linked to eating beef contaminated with the BSE (“mad cow”) agent. It tends to affect younger people, often starts with psychological or sensory symptoms, and shows a characteristic “pulvinar sign” on MRI (abnormal thalamus signal). A small number of blood-transmission cases have been documented in the UK. nhs.ukPMCECDC
Causes
Strictly speaking, all CJD is caused by misfolded prion protein in the brain. Below are 20 concrete origins or pathways that can lead to that misfolding—grouped as spontaneous, genetic, and acquired sources.
A) Spontaneous (no clear external trigger)
Random prion misfolding (sCJD) – a normal prion protein flips into the bad shape by chance, most often in later life, then spreads. nhs.uk
Older age – not a direct cause, but the risk rises with age; most cases occur after 55–60 years. CDCMayo Clinic
Genetic background at PRNP codon 129 (MM or VV homozygosity) – a common genetic pattern that raises susceptibility to sporadic disease (it doesn’t guarantee disease). Frontiers
B) Genetic (heritable—mutations in the PRNP gene)
PRNP E200K mutation – a well-known cause of familial CJD clusters (e.g., in some Mediterranean families). PMC
PRNP D178N (with 129V haplotype) – can present as familial CJD (D178N with 129M usually causes fatal familial insomnia; with 129V it can cause fCJD). BioMed Central
PRNP V180I mutation – described in East Asian cohorts with fCJD. BioMed Central
PRNP V210I mutation – another fCJD-associated change reported internationally. MDPI
PRNP M232R mutation – reported in familial prion disease series. BioMed Central
PRNP T188K mutation – a recurring mutation reported in Chinese cohorts with genetic prion disease. PMC
PRNP 5-octapeptide repeat insertion (5-OPRI) – an insertion in the repeat region that can lead to familial prion disease and sometimes looks like CJD. Nature
Other rare PRNP mutations (e.g., E196A/E196K, V203I, R208H, and more) – over 50 pathogenic PRNP variants are known worldwide that can cause genetic CJD. Nature
C) Acquired (exposure to external prions)
Cadaver-derived human growth hormone injections (historic) – prions were unknowingly present in some vials decades ago. CDC
Dura mater grafts (historic) – some graft materials carried prions from donors. CDC
Corneal transplants (historic) – very rare transmissions reported. CDC
Contaminated neurosurgical instruments (historic) – prions resist standard sterilization; special methods are now used. CDC
Stereotactic EEG depth electrodes (historic) – rare transmission events before modern sterilization. CDC
Dietary exposure to BSE (variant CJD) – eating heavily contaminated beef products in past outbreaks. ECDC
Blood transfusion from a donor incubating vCJD – a handful of UK cases documented; risk management policies followed. PubMedECDC
Plasma-derived products (variant risk, rare) – vCJD secondary transmission is possible via certain blood products; screening policies aim to reduce risk. ECDC
Laboratory or tissue handling accidents – theoretical or extremely rare occupational exposures are managed with strict protocols because prions resist inactivation. CDC
Common symptoms
CJD usually progresses fast. People often go from “almost normal” to “severely disabled” over weeks to months. Not everyone has every symptom, and the mix can differ by type (for example, variant CJD often starts with psychiatric symptoms). nhs.uk
Rapidly progressive confusion and memory loss – thinking slows, short-term memory fails, and routine tasks become hard within weeks.
Personality or behavior change – apathy, anxiety, irritability, depression, or social withdrawal can appear early and worsen. nhs.uk
Difficulty concentrating – attention fades quickly; conversations and instructions are hard to follow.
Speech problems – words come out slowly or incorrectly; sentences break down.
Trouble with balance and walking (ataxia) – unsteady steps, veering, or frequent falls; stairs feel risky.
Shaking jerks of muscles (myoclonus) – brief, shock-like jerks, often triggered by sound or touch; very suggestive when seen with the other signs.
Stiff or rigid muscles – limbs resist movement; body feels “wooden.”
Slowness and movement poverty – actions take longer; facial expression may look blank.
Vision problems – blurred or double vision, visual misjudgment of distance, or sometimes cortical blindness.
Sleep disturbance – poor sleep or altered day-night rhythm; in some genetic forms, sleep can be profoundly disrupted.
Mood and psychiatric symptoms – anxiety, depression, unusual fears, or hallucinations; in variant CJD, mood/behavior changes may precede obvious neurologic signs. nhs.uk
Sensory changes – odd pains, tingling, or changes in how sounds and sights feel, especially early in vCJD. nhs.uk
Difficulty swallowing – choking on liquids or solids; weight loss can follow.
Seizures – not in every patient, but can occur as the disease advances.
Akinetic mutism in late stage – the person is awake but mute and not moving purposefully; this reflects widespread brain injury.
How doctors diagnose CJD:
There is no single simple blood test. Doctors combine history, exam, and specialized tests to rule out look-alikes and support a CJD diagnosis during life. A definite diagnosis still requires brain tissue examination (usually done after death). In everyday practice, a firm “probable CJD” diagnosis is often possible before death using the tests below—especially MRI and RT-QuIC. nhs.ukMayo Clinic
A) Physical exam
Full neurologic exam
The doctor checks mental status, cranial nerves, strength, tone, reflexes, coordination, gait, and balance. In CJD, they often find rapid decline in cognition, abnormal reflexes, rigidity, and ataxia. This bedside picture raises suspicion and guides the next tests. CDCGait and balance assessment
Simple walking and turning tests reveal unsteady steps, wide-based stance, and difficulty with tandem walking. This matches cerebellar and basal ganglia injury typical in CJD.Visual and eye movement exam
Doctors look for visual field loss, trouble with tracking, or cortical visual problems. Visual symptoms can be prominent in some forms, and they help separate CJD from purely psychiatric disease.Myoclonus observation and startle testing
Brief muscle jerks, especially when startled by sound or touch, are a classic clue. Seeing stimulus-sensitive myoclonus is highly suggestive in the right clinical setting.
B) Manual/bedside tests
Mini-Mental State Examination (MMSE)
A quick screen of orientation, attention, memory, and language. In CJD, scores often drop quickly over weeks.Montreal Cognitive Assessment (MoCA)
A more sensitive screen for early executive and visuospatial changes; it often shows deficits early in CJD.Finger-to-nose and heel-to-shin tests
These simple coordination tests often show ataxia and dysmetria in CJD.Rapid alternating movements & pronator drift
Slowed or clumsy hand movements and a drifting weak arm support subcortical and cortical involvement.Romberg and tandem gait
Standing with feet together (eyes open/closed) and heel-to-toe walking often reveal instability that fits with CJD’s cerebellar involvement.
C) Lab & pathological tests
CSF RT-QuIC (Real-Time Quaking-Induced Conversion)
This is the key modern test. It detects minute amounts of misfolded prion “seeding” activity in cerebrospinal fluid. Large studies show very high accuracy—~90–97% sensitivity and ~100% specificity for sporadic CJD in many series. It lets clinicians make a probable diagnosis in life with strong confidence. NatureLippincott JournalsCSF 14-3-3 protein
A supporting marker of rapid brain injury; helpful but less specific, because it can be elevated in other acute brain problems (stroke, inflammation, seizures). It is often ordered alongside RT-QuIC. bjhlab.testcatalog.orgCSF total tau (t-tau)
Another injury marker that is usually very high in CJD but is not specific by itself; used with other results. dlmp.uw.eduPRNP gene testing (blood)
Looks for pathogenic mutations that cause familial CJD; supports diagnosis and guides family counseling. ScienceDirectBrain biopsy / autopsy with prion staining
Microscopy shows spongiform change, and special methods (e.g., immunohistochemistry or Western blot for PrP^Sc) confirm the diagnosis. In practice, definitive confirmation most often occurs after death. nhs.ukTonsil biopsy (selected vCJD cases)
Variant CJD can involve lymphoid tissue. Tonsil biopsy can detect prions in vCJD and has been used to support diagnosis in atypical cases. The Lancet
D) Electrodiagnostic tests
EEG (electroencephalogram)
In sporadic CJD, EEG often shows a characteristic pattern called periodic sharp-wave complexes (PSWC) at about 1 Hz. Sensitivity varies by stage (commonly ~60–70%), but when present, it’s strong supportive evidence. PMC+1Somatosensory evoked potentials (SSEPs)
These may show cortical conduction abnormalities that support diffuse brain dysfunction, helping rule in a rapid neurodegenerative process when EEG is not definitive.Polysomnography (sleep study)
Not routine for most CJD, but in some genetic prion diseases sleep can be profoundly disrupted; abnormal sleep architecture can be a supporting clue when the history suggests it.
E) Imaging tests
Brain MRI with DWI and FLAIR
MRI is highly useful. In sCJD, diffusion-weighted imaging (DWI) and FLAIR often show “cortical ribboning” and basal ganglia hyperintensity. Studies report high sensitivity and specificity for these sequences when read by experienced neuroradiologists. AJNRPMCMRI “pulvinar sign” in variant CJD
In vCJD, the posterior thalamus (pulvinar) often lights up brighter than other regions. This “pulvinar sign” is a helpful imaging clue that supports the diagnosis in the right clinical context. PMC

Drug treatments
No drug has proven to stop human CJD. The medicines below are used to ease distressing symptoms. Doses must be individualized by a clinician, especially because swallowing and kidney/liver function can change quickly.
Clonazepam (benzodiazepine) – for myoclonus (sudden jerks) and anxiety
Typical adult dose: 0.25–0.5 mg at night, then 0.5–2 mg/day divided (doctor adjusts).
Purpose/Mechanism: Boosts GABA signaling to calm overactive neuronal firing.
Side effects: Sleepiness, confusion, falls, breathing suppression with higher doses or other sedatives.Sodium valproate (broad antiepileptic) – for seizures and myoclonus
Typical dose: start ~10–15 mg/kg/day; titrate based on response and levels.
Mechanism: Increases GABA and stabilizes neuronal membranes.
Side effects: Tremor, liver toxicity, low platelets; avoid in pregnancy.Levetiracetam (antiepileptic) – for seizures and sometimes myoclonus
Typical dose: 500–1,500 mg twice daily (renal dosing needed).

Side effects: Fatigue, mood changes (irritability).Quetiapine (atypical antipsychotic) – for severe agitation/psychosis
Typical dose: 12.5–25 mg at night; gently titrate.
Mechanism: Dopamine/serotonin receptor modulation.
Side effects: Sedation, low blood pressure, metabolic effects; may worsen falls—needs close supervision.Sertraline (SSRI) – for depression/anxiety
Typical dose: 25–100 mg daily.
Mechanism: Increases serotonin signaling.
Side effects: Nausea, sleep change, hyponatremia in older adults.Baclofen (antispasticity) – for rigidity/spasticity
Typical dose: 5 mg 1–3×/day, increase slowly up to 20 mg 3×/day if tolerated.
Mechanism: GABA-B agonist reduces muscle tone.
Side effects: Drowsiness, weakness; abrupt stop can cause withdrawal.Trazodone (sedating antidepressant) – for insomnia and agitation at night
Typical dose: 25–50 mg at bedtime.
Mechanism: Serotonin modulation plus sedation.
Side effects: Dizziness, rare low blood pressure.Opioids (e.g., morphine) – for moderate–severe pain or breathlessness
Typical dose: individualized; start low, go slow; consider liquid for swallowing issues.
Mechanism: Mu-opioid receptor agonism reduces pain perception.
Side effects: Constipation, sedation, nausea; use bowel regimen and careful monitoring.Doxycycline (investigational/repurposed) – not proven to change outcomes in human CJD
Typical research dose: 100 mg twice daily in studies.
Evidence note: Mixed/negative clinical evidence; not a standard treatment.
Side effects: Photosensitivity, GI upset; avoid if not in a clinical protocol.Quinacrine (investigational, historical) – did not improve survival in randomized studies
Historic trial dose: 300 mg/day; Class I evidence shows no survival benefit. Not recommended outside research.
Side effects: Liver toxicity, yellow skin discoloration, GI upset. PMC
Why not list a “disease-stopping” pill?
Because we do not have one yet. Early experimental work shows promise (e.g., anti-prion antibodies), but these are not licensed and are available only in research settings. PubMedUCL Hospitals
Dietary “molecular” supplements
No supplement is proven to slow CJD. Use only with a clinician’s guidance—interactions and swallowing issues are common. The doses below are typical general-wellness ranges, not disease-specific.
Omega-3 (EPA/DHA) – 1 g/day with food
Function: May support general heart/brain health; can help maintain calories.
Mechanism: Anti-inflammatory lipid mediators in membranes.Vitamin D3 – 800–2,000 IU/day (adjust to blood levels)
Function: Bone/muscle support if mobility declines.
Mechanism: Nuclear receptor signaling improves calcium balance.Vitamin B1 (Thiamine) – 50–100 mg/day
Function: Prevents deficiency-related confusion in malnourished states.
Mechanism: Cofactor for brain energy metabolism.Vitamin B12 – 1,000 mcg/day oral or per clinician plan
Function: Supports nerve/myelin health if levels are low.
Mechanism: DNA synthesis and myelin maintenance.Magnesium – 200–400 mg elemental/day
Function: Eases constipation/cramps; supports sleep.
Mechanism: Smooth-muscle relaxation; NMDA modulation.Coenzyme Q10 – 100–200 mg/day
Function: General mitochondrial support (no proven benefit in CJD).
Mechanism: Electron transport cofactor/antioxidant.MCT oil – 1–3 tablespoons/day as tolerated
Function: Easy calories when appetite is poor.
Mechanism: Rapidly absorbed medium-chain fats.Whey or plant protein powder – 10–20 g/day
Function: Supports muscle mass and wound healing.
Mechanism: Amino acids for repair.Probiotic with lactobacillus/bifidobacterium – 10–20 billion CFU/day
Function: May reduce antibiotic-associated diarrhea or constipation.
Mechanism: Microbiome support.Psyllium husk/fiber – 3–10 g/day with water
Function: Keeps stools soft; lowers straining risk.
Mechanism: Forms gel to retain water in stool.
Regenerative / stem-cell” approaches—what the science actually says
There is no immune booster, stem-cell product, or regenerative drug proven to treat CJD. Below are research strategies being explored. They are not available as routine care and may only be accessible in clinical trials or preclinical studies.
Anti-prion monoclonal antibodies (e.g., PRN100)
Status: Small first-in-human program showed the drug reached the brain and was safe; a few patients appeared to stabilize at target levels, but this is not proof of efficacy. No approval. Dose: individualized in research; not for routine use.
Mechanism: Binds normal prion protein (PrP) to block conversion to the misfolded form. PubMedUCL HospitalsAntisense oligonucleotides (ASOs) targeting PRNP (e.g., ION717)
Status: In mice, lowering PrP extends survival; human trials are being developed/initiated by companies like Ionis (timelines change). Dose: research-only.
Mechanism: Lowers PrP production by degrading PRNP mRNA. PMCOxford AcademicSciencesiRNA-based PrP lowering (including divalent siRNA)
Status: Preclinical studies suggest potent gene silencing in the CNS; human dosing not established.
Mechanism: RNA interference reduces PRNP expression (less substrate for misfolding). BioRxivResearchGateAAV-mediated epigenetic silencing of PRNP (e.g., CHARM editor)
Status: 2024 animal data show brain-wide PRNP silencing; human trials have not established safety/efficacy yet.
Mechanism: Programmable methylation reduces PRNP transcription. PMCSmall-molecule aggregation modulators (e.g., anle138b in genetic models)
Status: Mouse studies explore whether blocking pathological protein assembly helps; no human proof in CJD.
Mechanism: Interferes with oligomer formation. ASM JournalsStem-cell transplantation
Status: Not recommended for CJD—no evidence it helps, and it could pose risks.
Mechanism (theory): Replace injured cells or deliver trophic factors; not borne out in human prion disease.
Bottom line: these are research directions, not established therapies. If you’re considering trials, ask your neurology team about eligibility and reputable registries.
Surgeries / procedures
There is no surgery that treats or cures CJD. A few procedures may be considered for comfort, nutrition, or diagnosis in very select situations, always with careful discussion.
Brain biopsy (diagnostic, rarely used)
Why: When non-invasive tests remain inconclusive and another treatable disease is still suspected.
How: Small tissue sample; requires prion-specific instrument handling.Percutaneous endoscopic gastrostomy (PEG) feeding tube
Why: If swallowing becomes unsafe and the person/family wish to continue nutrition/medications through the gut.
Note: Benefits vs. burdens must be discussed; goals of care matter.Tracheostomy
Why: Very rarely, to support breathing when aspiration or respiratory failure occurs and full life-prolonging support is consistent with goals.
Note: Intensive care needs are high; families should understand trajectory.Intraventricular catheter placement (historical/experimental)
Why: In a few case reports, catheters delivered pentosan polysulfate into brain ventricles; not standard, unclear benefit, and carries risks. PMCJournal of NeurologySurgical management of advanced pressure injuries or severe contractures
Why: Rarely, to treat complications when conservative measures fail and if consistent with comfort goals.
Prevention points
Most sporadic CJD cannot be prevented; it starts without a clear trigger.
Healthcare settings follow WHO/CDC prion-specific decontamination steps for high-risk tissues (brain/eye) and may use single-use instruments to prevent iatrogenic spread. CDCWHO Apps
Surgical instrument reprocessing (when indicated) uses validated prion protocols (e.g., soaking in 1N NaOH or ~20,000 ppm chlorine bleach plus autoclaving). These are facility-level procedures, not home tasks. CDC Stacks
Organ/tissue/medical-product screening and modern sourcing practices have made iatrogenic transmission extremely rare.
Food safety rules introduced after BSE have sharply reduced vCJD risk in many countries; avoid products that could contain brain or spinal tissues.
Genetic counseling can help families with known PRNP mutations understand testing and planning.
Do not donate blood, tissues, or organs if you have CJD or are at high risk.
Standard caregiving (touching, hugging, sharing a home) does not spread CJD.
Report unusual clusters to public health; surveillance helps maintain safety.
Choose well-regulated healthcare and dental settings that follow infection-control policies.
When to see a doctor—right away
See a doctor urgently (and request neurology input) if anyone develops rapidly worsening: memory loss, confusion, personality change, visual problems, clumsiness, jerking movements (myoclonus), slurred speech, trouble walking, or swallowing. If symptoms escalate over days to weeks, seek emergency care. Early evaluation speeds supportive care and testing. CDC
“What to eat” and “what to avoid
Eat more of (as tolerated):
Soft, moist, high-calorie foods (scrambled eggs, yogurt, mashed potatoes with olive oil) to keep weight up.
Protein-rich options (well-cooked lentils, fish, tofu, tender chicken) for strength and wound healing.
Smooth energy drinks or shakes when solid food is hard.
Hydrating liquids (water, oral rehydration solutions, broths) sipped throughout the day.
Fiber-friendly sides (oats, pureed fruits/veg) to prevent constipation.
Avoid or limit:
- Dry, crumbly, or mixed-texture foods (nuts, dry crackers) that increase choking risk.
- Alcohol and excess caffeine, which may worsen confusion or sleep.
- Very tough, stringy meats that are hard to chew/swallow.
- Huge meals—large portions can be exhausting; use small, frequent meals.
- Unregulated animal products from unknown sources; follow food-safety guidance.
A registered dietitian and speech-language pathologist can tailor textures and fluids to the person’s swallowing safety.
Frequently asked questions (FAQs)
Is CJD contagious like a cold?
No. It does not spread through casual contact, coughing, or everyday caregiving. Special precautions are only needed for certain medical procedures involving high-risk tissues. CDCIs there a cure right now?
No. Care is supportive. Trials are testing strategies like antibodies and PrP-lowering therapies. PMCPubMedHow is CJD confirmed?
A combination of MRI, EEG, spinal-fluid biomarkers, and RT-QuIC can establish a probable diagnosis in life; definite confirmation is by brain tissue. PMCFrontiersWhat is RT-QuIC?
A lab test that detects prion “seeding” activity; studies show very high specificity and high sensitivity for sCJD. FrontiersHow fast does CJD progress?
Usually over months; many people decline significantly within 4–12 months after symptoms begin. CDCCan vitamins or special diets stop CJD?
No. Nutrition supports comfort and strength, but it does not halt the disease.Is it safe to care for a loved one at home?
Yes, with standard hygiene. Follow professional advice for lifting, feeding, and preventing sores.Could this be genetic in our family?
Sometimes. A PRNP gene change causes familial prion disease. A genetics team can advise about testing and implications.Are there any promising drugs in people yet?
An antibody called PRN100 reached the brain and was safe in a small series; some stabilization was observed, but efficacy isn’t proven and there’s no approval. PubMedUCL HospitalsDid older “anti-prion” pills help?
Quinacrine did not improve survival in rigorous trials, so it isn’t recommended. PMCWhat about pentosan polysulfate delivered into the brain?
Only case reports/series; unclear benefit and significant risks. Not standard care. PMCCan brain surgery remove the prion?
No. Surgery does not treat CJD and introduces strict instrument-handling issues.Can blood tests diagnose CJD?
There’s no routine blood test that confirms it. Diagnosis relies on MRI/EEG/CSF and RT-QuIC.Do hospitals take special sterilization steps?
Yes—WHO/CDC prion protocols for instruments that contact high-infectivity tissues. WHO AppsCDC StacksWhere can we learn about trials?
Ask your neurology team and national prion surveillance/advocacy groups; they can point to reputable, ethics-approved studies.
