Sleep-Deprived EEG Testing in Drummoyne, Sydney
Sleep-deprived EEG testing is a specialised diagnostic procedure offered at our neurology practice in Drummoyne, Sydney. By inducing sleep deprivation prior to the test, we can increase the chance of detecting abnormal electrical activity that may not be visible during routine EEG tests, providing more accurate diagnoses for patients throughout Sydney, NSW and Australia.
When Is a Sleep-Deprived EEG Recommended?
Sleep-deprived EEG testing is typically performed in the following situations:
- When there is a high suspicion of a seizure or epilepsy
- When routine EEG testing conducted during wakeful periods have failed to reveal significant abnormalities
- When routine EEG testing showed minor changes that were not diagnostic, or were inconclusive
Potential Risks and Considerations
While sleep-deprived EEG testing is generally considered safe, there are a few potential considerations associated with the procedure:
- Temporary effects of sleep deprivation (fatigue, irritability)
- Slightly increased seizure risk during the testing period
- Minimal discomfort or skin irritation at electrode sites
- Potential for false-negative results in some cases
The Testing Procedure
Before the Test
Patients are advised to restrict their sleep before the procedure, ensuring they receive minimal sleep for a predetermined period. Typically, patients should stay awake for 24 hours prior to their test. This usually means staying awake for one night and having the EEG performed in the morning after being awake for the full 24-hour period.
During the Test
- Electrodes are attached to the patient's scalp using a mild adhesive
- These electrodes measure the electrical activity in different regions of the brain
- The information is transmitted to a computer, which records and analyses the data
- The test lasts approximately one hour and will be conducted while the person is in a drowsy or sleeping state
Preparation Guidelines
To prepare for sleep-deprived EEG testing at our Drummoyne clinic, patients are advised to follow these guidelines:
Consultation
Prior to the test, patients have a consultation with their healthcare provider to discuss the purpose and procedure of the test, as well as any specific instructions.
Sleep Schedule
Patients are instructed to maintain a regular sleep schedule leading up to the test and to avoid excessive caffeine, alcohol or stimulant consumption.
Medications
Patients should inform their healthcare provider about any medications they are taking, as certain drugs may interfere with the test results.
On the Day
Patients will be sleep deprived on the day of the testing. Therefore, it is recommended that they are accompanied to our Drummoyne clinic and do not drive themselves.
After the Test
After the test, patients can resume their regular sleep patterns. Our neurologists will review the recorded brain wave patterns and interpret the results.
Result Interpretation
Interpreting a sleep deprivation EEG involves analysing the recorded brain wave patterns during a state of sleep deprivation.
Our specialised neurologists in Drummoyne carefully analyse the EEG recordings, observing normal patterns and identifying specific characteristics and abnormalities in the brain wave activity.
The focus is on identifying any abnormal brain wave patterns, such as epileptic discharges, slow waves, or other anomalies that may indicate underlying neurological disorders.
This detailed analysis can take several days. To obtain the results of the test, you will need to make an appointment with the doctor who referred you.
Cost and Booking Information
The cost of a sleep deprivation EEG test can vary depending on several factors, including the cause and severity of the condition being investigated.
