In the ICU management of TBI, continuous EEG primarily helps by detecting which of the following?

• A. Detects subclinical seizures and nonconvulsive status epilepticus.
• B. Detects brain death.
• C. Measures intracranial pressure.
• D. Detects hypoxia.

Answer: (A)

Continuous EEG in the ICU after severe TBI is used to uncover seizures that aren’t clinically obvious. Subclinical seizures and nonconvulsive status epilepticus can occur without outward signs, yet they keep the brain in a stressed, metabolically burdened state that can worsen injury and hinder recovery. Detecting these events with prolonged electrical monitoring lets clinicians tailor antiseizure treatment promptly, aiming to protect brain tissue and improve outcomes. EEG doesn’t measure intracranial pressure or oxygenation directly, which are assessed with dedicated ICP monitors and oxygenation/MRI/arterial blood gas tools, respectively. Brain death evaluation relies on clinical criteria and specific ancillary tests rather than continuous EEG alone, though EEG may be used in broader assessments.
