Introduction
Whether seizures will occur after spikes appear on EEG usually depends on the patient's specific condition—it may or may not happen. It is recommended that patients actively cooperate with their doctors to complete relevant examinations to assist in diagnosis. If symptoms of epilepsy occur, medications such as carbamazepine tablets or levetiracetam tablets should be taken under medical guidance for treatment.

Whether seizures will occur after the appearance of spike waves on an electroencephalogram (EEG) usually depends on the patient's specific condition. Seizures may or may not happen. The detailed analysis is as follows:

1. Situations without seizures

The presence of spike waves on EEG typically indicates abnormal electrical activity in the brain and is considered a type of epileptiform wave. If the EEG shows isolated spike waves without obvious clinical symptoms, and brain CT or MRI scans reveal no definite organic lesions, and if daily care and monitoring are well maintained, the patient may never experience a seizure. In such cases, treatment might not be necessary immediately; regular follow-up visits with a physician are sufficient.

2. Situations with seizures

If the patient has a known history of epilepsy, experiences clear epileptic symptoms, and imaging studies reveal organic brain lesions, failure to adhere to prescribed medications or regular follow-up appointments may lead to seizure episodes.

It is recommended that patients actively cooperate with their doctors to complete relevant examinations for accurate diagnosis. If epileptic symptoms do occur, medications such as carbamazepine tablets or levetiracetam tablets should be taken under medical supervision.
