Interpretation of EEG Report
Due to a headache, an EEG report was conducted.
Since the follow-up appointment is in two weeks, I checked the health insurance app and the report has been uploaded.
EEG description: This EEG was performed when the patient was awake and at rest (GCS = E4V5M6).
The background activity consists of symmetric alpha activities at 10-11 Hz, 40-80 µV in the posterior head areas with adequate reactivities to alerting maneuvers.
Prominent beta rhythms around 15-25 Hz, 10-35 µV are noted in the whole head areas.
Hyperventilation was not performed.
Photic stimulation elicited no photic driving response.
Doctor, regarding my beta waves, does the report indicate that they are elevated? Is there anything abnormal in my EEG report?

Dear Ms.
Yue,
You mentioned, "Is the beta wave high according to the report?" Your report indicates that it is within the normal range.
Typically, beta waves increase when we are engaged in thought processes.
It is possible that during the EEG, you were actively thinking.
Additionally, sedative medications can also increase beta waves.
EEG results should be interpreted in conjunction with clinical symptoms, so I recommend discussing this with your attending physician.
Thank you for your question, and feel free to reach out for further discussions on related topics!
Wishing you good health, peace, and happiness.
Dr.
Jiang Junyi, Taoyuan Medical Center, cares about you.

Understanding your EEG report can be quite daunting, especially when you are experiencing symptoms like headaches. Based on the EEG description you provided, it appears that your report shows a predominance of beta waves, which are typically associated with active thinking, alertness, and cognitive processing.
In your EEG report, the beta rhythms are noted to be prominent in the range of 15-25 Hz with amplitudes of 10-35 µV across the entire head. While this may seem concerning at first glance, it is important to understand the context of beta waves. Elevated beta activity can occur during states of heightened mental activity, anxiety, or stress. It is not uncommon for individuals who are undergoing EEG testing to exhibit increased beta activity simply because they are thinking or worrying about the test itself or their health condition.
The report also indicates that you have symmetric alpha activity at 10-11 Hz in the posterior head areas, which is a normal finding. Alpha waves are typically associated with a relaxed, calm state, and their presence suggests that your brain was able to achieve a state of rest during the recording. The fact that there was adequate reactivity to alerting maneuvers further supports that your brain is functioning normally in terms of responsiveness.
Regarding your question about whether your beta waves are "high," it is essential to note that the presence of beta waves is not inherently abnormal. The amplitude and frequency of beta waves can vary significantly among individuals and can be influenced by various factors, including medication, mental state, and even the specific circumstances during the EEG recording. In your case, the report does not indicate any pathological findings, and the overall interpretation suggests that your EEG is within normal limits.
However, if you are experiencing persistent headaches, it is crucial to discuss these symptoms with your healthcare provider. While the EEG results may not show any immediate abnormalities, your clinical symptoms should guide further evaluation and management. Your doctor may consider additional tests or treatments based on your headache patterns, frequency, and severity.
In summary, your EEG report does not indicate any significant abnormalities, and the presence of beta waves can be attributed to your mental state during the test. It is advisable to follow up with your physician to discuss your headaches and any other symptoms you may be experiencing. They can provide you with a comprehensive evaluation and determine if any further investigations are necessary. Remember, understanding your health is a collaborative process between you and your healthcare provider, and open communication is key to addressing your concerns effectively.
