Which pattern is associated with Creutzfeldt-Jakob disease?

• A. Polyspike complex
• B. Spike and wave complex
• C. Multifocal sharp waves
• D. Periodic sharp waves

Answer: (D)

The pattern associated with Creutzfeldt-Jakob disease is characterized by periodic sharp waves. In patients with this neurodegenerative disorder, the EEG findings often reveal these periodic sharp wave complexes, which typically occur at regular intervals, indicating a form of cortical irritability. This is distinct from other patterns that might not be specifically linked to the pathology of Creutzfeldt-Jakob disease. Periodic sharp waves can help differentiate Creutzfeldt-Jakob disease from other types of encephalopathies, as this finding is relatively unique to prion diseases. The presence of these waves is correlated with the rapid progression of cognitive decline and other clinical features of the disease. Understanding this specific EEG pattern is crucial for the diagnosis and management of patients suspected of having Creutzfeldt-Jakob disease.
