Which modality is explicitly mentioned as a tool for neuroprognostication?

• A. Functional MRI
• B. EEG only
• C. SSEP only
• D. EEG and SSEP

Answer: (D)

Neuroprognostication after brain injury relies on tests that reflect brain activity and the integrity of sensory pathways. EEG records spontaneous electrical brain activity and helps identify patterns associated with poor outcomes, such as nonreactive or severely abnormal activity. SSEP measures the brain’s response to sensory stimulation; the bilateral absence of the cortical N20 response is a strong, widely used predictor of poor prognosis. While functional MRI can provide valuable information in certain contexts, it isn’t routinely cited as an explicit prognostic tool in standard guidelines. Therefore, the combination of EEG and SSEP covers the modalities explicitly referenced for prognosis, making EEG and SSEP the best choice.
