Maybe it’s not CJD

When you go to your doctor with suspected Creutzfeldt-Jakob disease, your doctor’s first mission is to rule out other illnesses that might look like CJD. Because CJD can affect many different areas of the brain, it can lead to a variety of symptoms, some of which can mimic other neurological diseases. The good news is that many of these other diseases are treatable.

Similar symptoms and rapid progression can occur in association with brain inflammation, intermittent seizures, metabolic disorders (like vitamin deficiencies), vascular disease of the blood vessels in the brain, Alzheimer’s disease and dementias associated with Parkinson’s disease.

Typically, your doctor will perform a standard neurological examination and request other diagnostic tests such as:

• lumbar puncture to rule out more common causes of dementia and look for signs of an infection,
• electroencephalogram (EEG) to record the brain’s electrical activity, which can be distinctive in CJD, and
• brain imaging either by computerized tomography (CT) to rule out stroke and tumor or magnetic resonance imaging (MRI) to exclude other forms of dementia or reveal characteristic patterns of CJD.

The information from these tests will help your doctor determine if you have something treatable or if you need further testing for CJD.
