Creutzfeldt-Jakob Disease: Causes, Symptoms, and Treatment

What kind of doctor treats Creutzfeldt-Jakob disease?
Creutzfeldt-Jakob disease, a rare and fast-moving brain condition, is managed by a neurologist (brain and nerve doctor). The disease cannot be reversed, so care focuses on comfort, safety, and support for the family, often with help at home or in a care facility as it progresses over weeks to months.
What is Creutzfeldt-Jakob disease?
Creutzfeldt-Jakob disease, or CJD, is a rare, rapidly progressing brain disorder. It belongs to a family called prion diseases.
CJD is caused by abnormal forms of proteins called prions. Abnormal prions can clump together and build up in the brain. This may lead to nerve cell loss and other brain damage.
Classic CJD is always fatal. It usually moves fast. People usually die within a year after symptoms start.
Symptoms
The main symptoms are dementia, muscle jerks, and poor coordination. Dementia may get worse quickly, over a few weeks or months.
Early symptoms may include:
- Poor coordination.
- Walking and balance problems.
- Confusion and disorientation.
- Problems with thinking, memory, and judgment.
- Mood changes, such as depression and anxiety.
- Trouble speaking.
- Vision changes.
- Changes in sleep.
Later symptoms can include weak arms and legs, blindness, and trouble swallowing. People may be unable to move or speak, and may fall into a coma.
Some symptoms look like Alzheimer's disease. But in CJD they tend to get worse faster.
Causes and who gets it
CJD occurs worldwide, mostly in older adults. The average age is in the late 60s. Very few cases occur in people younger than 30.
There are three main types:
- Sporadic CJD, about 85 percent of cases, happens for reasons that are not fully understood.
- Familial CJD happens when a person inherits a change in the prion protein gene.
- Acquired CJD comes from contact with prions in a healthcare setting or from biological products.
CJD cannot spread through the air or by touching or most other casual contact. Variant CJD comes from eating meat from cattle with mad cow disease.
How doctors diagnose it
A neurologist does a physical exam and asks about health history. Tests may include an MRI of the brain. They may also include an EEG, which records brain activity. A spinal tap can test the fluid around the brain and spinal cord.
The only way to confirm CJD is by testing brain tissue from a biopsy or autopsy.
Treatment
There is no cure for CJD. Different medicines have been tried to slow it, but none works well.
Treatment focuses on comfort and support. The goals include a safe environment, control of agitation, and meeting the person's needs. This may need help at home or in a care facility.
When to see a doctor
See a doctor if dementia is getting worse quickly. Also see one for jerky movements or trouble walking.
Call 911 or go to the emergency room for a seizure, fainting, or trouble breathing.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A direct primary care doctor can do a first check of memory or movement changes. They can refer you to a neurologist. They can also help families find care services.
Common questions
What are the first signs of Creutzfeldt-Jakob disease?
Early signs can include memory problems, personality changes, trouble with coordination, and dementia that gets worse quickly over weeks to months. A healthcare provider, typically a neurologist, diagnoses it using a physical exam and the person's medical history.
Is Creutzfeldt-Jakob disease contagious?
Creutzfeldt-Jakob disease does not spread through everyday contact like touching or being near someone. In rare cases it has spread through certain medical procedures that exposed a person to infected brain or nervous system tissue.
Can a direct primary care doctor manage Creutzfeldt-Jakob disease?
A direct primary care doctor cannot reverse this disease, but can help the family understand test results, coordinate with the neurologist, and arrange comfort-focused and home support care as the illness progresses.
