Which of the following symptoms is commonly associated with non-convulsive seizures in TBI patients?

Non-convulsive seizures are a specific type of seizure that can occur in individuals with traumatic brain injury (TBI). Among the symptoms listed, coma is commonly associated with non-convulsive seizures. This occurs because non-convulsive seizures can affect consciousness and may lead to a state resembling coma, where the patient appears unresponsive or minimally responsive but does not exhibit overt convulsions.

In contrast, severe headaches, fever, and paralysis can be symptomatic of various other conditions associated with TBI or other medical issues but are not specifically tied to non-convulsive seizures. Severe headaches might indicate increased intracranial pressure or other complications post-injury. Fever could suggest an infection or other systemic response, and paralysis is more commonly associated with direct injury to specific parts of the brain or spinal cord rather than seizures. Thus, the correct choice highlights the unique impact of non-convulsive seizures on consciousness in TBI patients.
