Abnormal Brain Waves in Children: Is It Epilepsy? - Neurology

The child's EEG shows abnormal discharges?


Hello Doctor: My child is currently 1 year and 6 months old.
At around 1 year and 3 to 4 months, I noticed that my child had episodes of trembling upon waking up.
We took him to the National Taiwan University Hospital in Yunlin for an EEG, which revealed abnormal electrical discharges in the brain.
Due to the trembling and the abnormal EEG findings, the physician suspected a possible diagnosis of epilepsy.
Recently, we have not observed any trembling episodes, so we have not started any medication for control.
Could you please advise if this situation indicates epilepsy? Is it possible to manage the condition without medication since the trembling episodes are infrequent? If my child is indeed diagnosed with epilepsy, will it affect his future physical and mental development? Thank you for taking the time to respond!

If you have not taken medication and do not have any clinical symptoms, you can return to the clinic and inform your physician.
They will likely perform another EEG to assess the brain's electrical activity to confirm the diagnosis.
If epilepsy is indeed present and not controlled by medication, the repeated discharges of brain cells can have a significant impact on the brain.
However, with medication, more than half of patients can achieve good control, and a substantial number may gradually become seizure-free and successfully discontinue medication.
For detailed information, you can consult your attending physician, especially a pediatric neurologist or an epilepsy specialist.

When it comes to understanding abnormal brain waves in children, particularly in the context of potential epilepsy, it is crucial to approach the situation with a comprehensive understanding of both the medical implications and the psychological aspects involved. Your child, at 1 year and 6 months, has shown some concerning symptoms, such as tremors upon waking, which led to an EEG (electroencephalogram) that indicated abnormal electrical discharges in the brain. This has raised the suspicion of epilepsy.

Firstly, it is important to clarify that the presence of abnormal brain waves does not automatically confirm a diagnosis of epilepsy. Epilepsy is characterized by recurrent seizures, which are caused by abnormal electrical activity in the brain. The fact that your child has not exhibited any tremors or seizures recently is a positive sign. It suggests that, while there may be some underlying abnormality in brain wave activity, it is not currently manifesting as clinical seizures.

In terms of treatment, the decision to initiate medication often depends on several factors, including the frequency and severity of seizures, the type of seizures, and the overall impact on the child's daily life and development. Since your child has not experienced any recent tremors or seizures, many pediatric neurologists may adopt a "watchful waiting" approach, monitoring the situation closely without immediately resorting to medication. This is particularly relevant in young children, as the side effects of anti-epileptic drugs can sometimes outweigh the benefits, especially if seizures are infrequent or absent.

However, it is essential to maintain regular follow-ups with a pediatric neurologist. They may recommend periodic EEGs to monitor any changes in brain activity over time. If your child does develop seizures in the future, the neurologist will have a clearer picture of the situation and can adjust treatment accordingly.

Regarding your concern about the potential impact of epilepsy on your child's future development, it is important to note that many children with epilepsy lead healthy, fulfilling lives, especially when the condition is well-managed. Early diagnosis and appropriate treatment can significantly mitigate any potential developmental delays or cognitive impairments. Factors such as the type of epilepsy, the age of onset, and how well the seizures are controlled play a significant role in determining long-term outcomes.

In the meantime, there are several proactive steps you can take to support your child's health and development. Ensuring a stable routine, promoting a healthy diet, and encouraging adequate sleep are all beneficial. Additionally, being aware of any triggers that may provoke seizures (such as lack of sleep, stress, or illness) can help in managing the condition.

Lastly, it is crucial to maintain open communication with your healthcare provider. If you notice any new symptoms or changes in behavior, do not hesitate to reach out for guidance. Early intervention can be key in managing any potential issues that may arise.

In summary, while the presence of abnormal brain waves raises valid concerns, the absence of seizures and tremors is encouraging. Regular monitoring and consultations with a pediatric neurologist will be essential in determining the best course of action for your child's health and development.
