A 68 yo M is admitted to the ICU for hypertensive urgency and acute renal failure requiring initiation of dialysis. Below is an epoch from his continuous EEG monitoring that was ordered for encephalopathy. How would you best describe the pattern seen on this epoch (pattern, frequency, location)?

• Generalized Periodic Discharges (GPDs), 1-2 Hz
• Generalized Rhythmic Delta Activity (GRDA), 1-2 Hz
• Lateralized Periodic Discharges (LPDs), 1-2 Hz, Left parieto-occipital
• Lateralized Periodic Discharges (LPDs), 1-2 Hz, Right parieto-occipital
• Lateralized rhythmic delta (LRDA), 1-2 Hz, Left parieto-occipital
• Lateralized rhythmic delta (LRDA), 1-2 Hz, Right parieto-occipital
