What is the typical clinical presentation of Creutzfeldt-Jakob disease?

• A. Seizures, dementia, coma, chronic vegetative state
• B. Progressive dementia, bilateral rigidity, myoclonus, stupor and death
• C. Mild dementia, focal seizures, gradual improvement after treatment
• D. Permanent memory loss with changes in personality

Answer: (B)

The clinical presentation of Creutzfeldt-Jakob disease (CJD) is characterized by a progressive decline in cognitive function, known as dementia, which is typically rapid and severe. Patients often exhibit bilateral rigidity, reflecting the neurological deterioration that occurs as the disease progresses. Myoclonus, which is a sudden and brief involuntary muscle jerking, is a hallmark symptom in many cases and often contributes to the overall neurologic decline. As CJD advances, individuals may enter a state of stupor, which is a state of near-unconsciousness, and ultimately, the disease leads to death within months to a few years following the onset of symptoms. This aggressive and progressive pattern of symptoms underlines why this choice accurately reflects the typical clinical presentation of CJD, distinguishing it from other conditions with different profiles or progression patterns.
