It is possible for a 6-year-old child with febrile convulsions and consistently abnormal brain waves to become epileptic.
Epilepsy is categorized into primary epilepsy and secondary epilepsy, which may usually manifest as neuroconsciousness and mental disorders, seizure movements and so on. The cause of primary epilepsy is not clear, it may be caused by genetic reasons and so on, and medication can give better results. The cause of secondary epilepsy can usually be clearly defined, such as organic lesions in the brain, febrile convulsions, etc., and drug treatment is usually ineffective.
In addition, the electroencephalogram during febrile convulsions is usually normal, but the brain waves during seizures are usually abnormally altered.
So 6-year-old child with febrile convulsions, brain waves have been abnormal, may lead to secondary epilepsy, so children once the occurrence of febrile convulsions, should promptly seek medical treatment to avoid induced epilepsy.
