CHILDREN EPILEPSY: How Does a Long-Term EEG Work ?
A long-term electroencephalogram (EEG) is a specialized neurological test conducted at the Children’s Hospital to analyze brain activity. On the occasion of International Epilepsy Day, let's take a closer look at this essential diagnostic tool.
A Key Examination for Neurological Diagnosis
A long-term EEG is a gold-standard test for evaluating brain activity and refining the diagnosis of various neurological conditions, such as epilepsy or unexplained loss of consciousness. This painless and non-invasive examination allows for prolonged observation of brain function in conditions similar to everyday life.
The EEG plays a crucial role in diagnosing and managing pediatric neurological disorders. It provides a detailed understanding of brain activity, helping specialists tailor the most appropriate treatment for each child
Before the Examination
Medical Referral
A child may be referred to a pediatric neurologist by their primary pediatrician or following an emergency visit due to seizures or unexplained loss of consciousness.
Neurology Consultation
During the appointment, the pediatric neurologist may prescribe an EEG to further investigate the diagnosis.
Appointment Scheduling
The pediatric neurology department at HUDERF arranges the EEG at the Children’s Hospital.
Hospital Admission
On the day of the exam, the child and their caregiver arrive at the hospital at 10 AM. They are introduced to their fully equipped room, where they will stay for the day and night.
Preparation
A nurse places multiple electrodes on the child's scalp using a soft mesh cap to ensure a secure and comfortable fit.
During the EEG: Continuous Monitoring
Start of Recording
The EEG recording begins and continues in several phases throughout the day and night.
Daytime Testing
Intermittent Light Stimulation: Exposure to flashing lights to assess brain reactivity.
Hyperventilation Test: Deep breathing exercises to analyze changes in brainwave activity.
Nighttime Observation
The child stays overnight in the hospital, accompanied by a parent, while the EEG recording continues during sleep.
Video Surveillance & EEG
The EEG is combined with video monitoring, allowing doctors to correlate brain activity with potential clinical symptoms.
After the EEG: Interpretation & Follow-Up
Electrode Removal & Cleaning
A shampoo is often necessary to remove the conductive paste used during the test.
Data Analysis
The EEG recordings are carefully reviewed by a team of pediatric neurologists, who compile a comprehensive diagnostic report.
Follow-Up Consultation
A follow-up appointment is scheduled with the pediatric neurologist. Based on the results, an appropriate treatment plan may be recommended.
