Epileptiform
Epileptiform
Epileptiform (/ɛpɪˈlɛptɪfɔːrm/; from the Greek epilepsia, meaning "seizure", and the Latin forma, meaning "shape or form") refers to a pattern of brain waves that is characteristic of an epileptic seizure. This pattern is typically identified through an electroencephalogram (EEG).
Etymology
The term "epileptiform" is derived from the Greek word epilepsia, which means "seizure", and the Latin word forma, which means "shape or form". It is used to describe brain wave patterns that resemble those seen in epileptic seizures.
Definition
Epileptiform discharges are abnormal patterns of electrical activity in the brain that are characteristic of epilepsy. These discharges can be seen on an EEG and are used to diagnose and monitor the condition. They can occur in a variety of forms, including spike-and-wave discharges, sharp waves, and polyspike discharges.
