Final answer:
The electroencephalogram (EEG) findings in Creutzfeldt-Jakob disease (CJD) show abnormal brain function, characterized by periodic sharp wave complexes and triphasic waves. These findings are helpful in the diagnosis of CJD.
Step-by-step explanation:
The electroencephalogram (EEG) findings in Creutzfeldt-Jakob disease (CJD) show abnormal brain function. The EEG resembles that of a patient with a neurodegenerative disease like Alzheimer's or Huntington's, but the rapid cognitive decline in CJD is not consistent with these diseases. The EEG findings in CJD are characterized by abnormal brain wave patterns, such as periodic sharp wave complexes and triphasic waves. These findings help in the diagnosis of CJD.
