Which condition is associated with PLEDs?

Which condition is associated with PLEDs?

• A. Metabolic disease
• B. Meningitis
• C. Acute cerebral infarction
• D. CJD

Answer: (C)

PLEDs, orPeriodic Lateralized Epileptiform Discharges, are a specific pattern observed on an electroencephalogram (EEG) that is associated with focal brain pathology. One of the well-established associations of PLEDs is with acute cerebral infarction, which refers to the sudden loss of blood circulation to an area of the brain, leading to tissue damage. When an area of the brain suffers an infarction, it may cause localized neuronal distress and dysfunction, resulting in the abnormal electrical activity seen as PLEDs. This is particularly evident in the area of the brain that is affected by the infarction, where there is often a change in the electrical properties of the neurons. Consequently, identifying PLEDs on an EEG can serve as a critical diagnostic feature indicating potential recent or ongoing cerebral ischemia by highlighting the correlation with acute cerebral damage. In contrast, while metabolic disease, meningitis, and Creutzfeldt-Jakob Disease (CJD) can feature abnormal EEG findings, they are not specifically characterized by PLEDs to the same extent as acute cerebral infarction. Therefore, the association of PLEDs with acute cerebral infarction underscores the significance of this particular EEG pattern in identifying and assessing focal brain injuries
