Management and Treatment of Creutzfeldt-Jakob Disease
There is no cure or disease-modifying treatment for CJD; management is entirely palliative, focused on symptom control and quality of life, with median survival of approximately 5 months from symptom onset. 1, 2
Confirm the Diagnosis First
Before initiating palliative care discussions, ensure diagnostic confirmation using the most accurate available testing:
- CSF RT-QuIC is the gold standard biomarker with 94-96% sensitivity and 100% specificity; a positive result alone is sufficient for probable CJD diagnosis. 1
- Brain MRI with DWI and FLAIR sequences showing T2 hyperintensity and diffusion restriction in cortical regions, caudate, and putamen supports the diagnosis. 1
- EEG may demonstrate periodic sharp wave complexes with 1:1 correlation to myoclonic jerks, which is highly characteristic. 1, 3
- CSF 14-3-3 protein and total tau elevation are supportive but less specific than RT-QuIC. 1
Symptomatic Management Algorithm
Myoclonus Control
- Treat myoclonic jerks pharmacologically using standard antimyoclonic agents (clonazepam, valproic acid, or levetiracetam), following principles similar to geriatric hospice care. 4
- Myoclonus can be severely distressing to patients and families and requires aggressive management. 4
Cognitive and Behavioral Symptoms
- Address rapidly progressive dementia, personality changes, and behavioral abnormalities with environmental modifications and caregiver education rather than pharmacologic intervention when possible. 1, 4
- Psychotropic medications may be needed for severe agitation but should be used cautiously given the rapid disease progression. 4
Motor Symptoms
- Manage extrapyramidal symptoms (rigidity, tremors) and cerebellar signs with physical therapy and positioning strategies. 2, 4
- As disease progresses to akinetic mutism, focus shifts to comfort measures and prevention of complications. 1, 2
End-Stage Care
- Prevent complications from immobility including pressure ulcers, aspiration pneumonia, and deep vein thrombosis. 4
- Address dysphagia and nutritional needs; discuss goals of care regarding artificial nutrition early in disease course. 4
Care Setting Considerations
- Early palliative care referral is critical given the rapid disease trajectory and median survival of 5 months. 1, 5
- Patients may be managed in neurological units, hospices, care homes, or at home depending on family resources and symptom burden. 5
- Input from clinicians with palliative care expertise is essential given the complexity of physical and psychosocial symptoms. 5
Family Support and Education
- Provide comprehensive education about disease progression, prognosis, and what to expect as the disease advances. 4
- Offer psychosocial support for families dealing with the devastating diagnosis and rapid decline. 5, 4
- Address bereavement support needs early, as families often experience complicated grief given the rapid trajectory. 5
Infection Control Precautions
- Implement appropriate precautions for transmissible prion disease, particularly in healthcare settings and for any invasive procedures. 5
- Educate healthcare personnel about transmission risks and proper handling of contaminated materials. 4
Critical Pitfalls to Avoid
- Do not delay palliative care referral while pursuing diagnostic confirmation; symptom management should begin immediately. 5, 4
- Do not pursue aggressive interventions or experimental therapies that compromise quality of life, as no disease-modifying treatments exist. 2, 6, 4
- Do not overlook the need for early goals-of-care discussions given the invariably fatal prognosis and rapid decline. 4, 7
- Avoid dismissing family concerns about rapid cognitive decline; CJD progresses over weeks to months, not years like typical dementias. 1, 6
