Which of the following EEG patterns is MOST likely associated with seizures?

The EEG pattern most commonly associated with seizures is TIRDA, or Triphasic Irregular Recurrent Discharges. This pattern is characterized by a specific waveform morphology that consists of triphasic spikes or sharp waves, which can occur frequently and are often seen in conditions associated with metabolic disturbances or encephalopathy. TIRDA is particularly notable during seizure activity, as it reflects the underlying abnormal cortical excitability that is key in the mechanisms of seizures.

When examining the other options, SREDA (Slowing Reversal of EEG Activity) generally does not exhibit the same level of electrographic disturbance that accompanies seizures. OIRDA (Occipital Intermittent Rhythmic Delta Activity) typically represents a benign phenomenon and is not directly associated with seizure activity. FIRDA (Frontal Intermittent Rhythmic Delta Activity) can appear in various brain states but is less indicative of seizures compared to TIRDA.

Thus, due to its specific characteristics and association with seizure activity, TIRDA is identified as the EEG pattern most likely associated with seizures.
