What would you expect to see on an EEG performed two days after a transient ischemic attack?

• A. polymorphic delta activity
• B. FIRDA
• C. focal suppression
• D. normal activity

Answer: (D)

In the context of an EEG performed two days after a transient ischemic attack (TIA), a finding of normal activity is expected. A TIA results in temporary and reversible neurological dysfunction due to a brief interruption of blood flow to the brain, but it does not typically lead to lasting structural changes or significant electrical abnormalities detectable by EEG, particularly after a short interval such as two days. During this time frame, the brain may return to its baseline electrical activity, leading the EEG to show normal patterns. This is in contrast to more severe neurological events, such as a stroke, where you might expect to see more prominent changes in the EEG that suggest underlying damage or dysfunction, such as focal abnormalities or nonspecific slow activity. Other options represent abnormal findings that could arise from different types of neurological insults or issues. Polymorphic delta activity and focal suppression would indicate more significant brain injury or dysfunction, which would not typically be present two days after a TIA. FIRDA (frontal intermittent rhythmic delta activity) can be associated with various forms of brain dysfunction and would not be expected following a TIA that resolves quickly. Thus, the expectation of normal activity reflects the transient and non-destructive nature of a TIA, aligning with the typical EEG findings in this
