Question:
Hello. My 7-year-old child recently had a seizure without a fever. They had a similar experience when they were about 16 months old, but their EEG test came back normal at that time. Currently, my child has tested positive for rhinovirus and has been diagnosed with pneumonia. I know we will likely need to repeat the EEG, but I am wondering if it is possible that the rhinovirus caused this afebrile seizure?
Answer:
It must have been very frightening to see your child experience a seizure without a fever.
To summarize your current situation: your child had an afebrile (without fever) seizure with a similar history at 16 months of age, recently tested positive for rhinovirus and pneumonia, and had a normal EEG in the past.
Regarding the relationship between rhinovirus and seizures: Rhinovirus primarily causes common cold and respiratory symptoms. While it can be associated with febrile seizures (seizures accompanied by a fever), it is very rare for it to directly cause an afebrile seizure.
When afebrile seizures happen more than once, it is necessary to consider other potential causes, such as epilepsy. It is worth noting, however, that an ongoing infection can lower a child's overall seizure threshold, which might act as a triggering factor even without a fever.
Ultimately, the repeated pattern of these afebrile seizures is a much more important clinical sign than the rhinovirus infection itself. Please inform your attending pediatrician about this recurrent afebrile seizure. It is highly recommended that you discuss repeating the EEG and arranging a consultation with a pediatric neurologist to accurately evaluate the cause and establish a proper care plan.
