What EEG pattern is associated with CJD disease?

The EEG pattern associated with Creutzfeldt-Jakob Disease (CJD) is characterized by periodic complexes, often referred to as sharp wave complexes. This pattern is notable because it typically presents as irregular, periodically recurring sharp waves or spikes, which are indicative of the disease's neurodegenerative process.

Periodic complexes are unique and are often seen in prion diseases like CJD due to the rapid degeneration of the cortical structures and the subsequent abnormal electrical activity. Detecting these complexes plays a crucial role in diagnosing CJD, as they serve as a key electrographic hallmark of the condition.

While other EEG patterns, such as spike-wave complexes, delta waves, and slow waves, may appear in various neurological disorders, they are not specific to CJD. This specificity of periodic complexes to CJD is why this option is the correct one for identifying the characteristic EEG changes associated with the disease.
