Question
The patient is 8 years old and has previously shown an abnormal EEG, characterized by short-term 4-6C/S activity at the occipital leads, 50-120Q activity, with a predominance of slow waves and a few fast waves. Does this indicate epilepsy? What does the meaning of fast waves entail?
Answer
Epilepsy is a disease caused by abnormal discharge of neurons in the brain. EEG can be used for diagnosing epilepsy, but not all abnormal EEGs indicate epilepsy. If the patient does not exhibit symptoms such as loss of consciousness or limb convulsions associated with epilepsy, even with an abnormal EEG, it may not necessarily be epilepsy. Conversely, even without an abnormal EEG, if there is a history of epilepsy, it could still be epilepsy. It is recommended to maintain a relaxed mood, regular lifestyle, appropriate exercise, and ensure adequate sleep to promote good health.
