[An EEG evaluation in diagnosing subacute spongiform encephalopathy]

Area of Science:

• Neurology
• Pathology

Background:

• Creutzfeldt-Jacob Disease (CJD) is a rare, fatal neurodegenerative disease.
• Subacute spongiform encephalopathies represent a group of prion diseases affecting the brain.

Observation:

• Three patients presented with typical clinical signs and disease progression of CJD.
• One case underwent pathological confirmation, validating the clinical diagnosis.

Findings:

• Electroencephalogram (EEG) recordings during the peak, progressing phase consistently showed persistent, periodical bursts.
• These characteristic EEG patterns were observed across all reported cases.

Implications:

• The specific EEG paroxysms identified are highly valuable for diagnosing Creutzfeldt-Jacob Disease.
• Early and accurate diagnosis can aid in patient management and further research into prion diseases.
