Yes, it's possible to have abnormal brain activity that shows up on an EEG without being aware of it. In fact, about half of EEG tests done on people who have seizures can look normal, and conversely, abnormal activity can be present without noticeable symptoms.

An ambulatory EEG is an excellent tool for catching these episodes since it records brain activity for an extended period (24 hours to three days) rather than just the standard 20-40 minutes. This longer monitoring period increases the chances of recording any abnormal brain activity. Even if the abnormal brain activity is only apparent on an EEG and you're not experiencing obvious symptoms, it's still considered a diagnosis that needs attention. Your healthcare provider may recommend treatment based on these findings to prevent the potential development of more noticeable seizure activity.
