Epileptiform discharges (EFDs) are abnormal electrical patterns in the brain that can be observed on an electroencephalogram (EEG). These discharges can be similar to those seen in seizures, but they are not necessarily indicative of a seizure disorder. EFDs are often seen in patients with certain medical conditions or as a result of medication side effects.

The presence of EFDs on an EEG can be due to a variety of factors, including underlying structural lesions in the brain, such as tumors or inflammatory conditions. EFDs can also be seen in patients with certain metabolic disorders or in patients who have recently suffered a head injury. In some cases, EFDs may be a side effect of medications, such as anticonvulsants or sedatives.

The appearance of EFDs on an EEG can vary depending on the underlying cause. They may be slow or fast, unilateral or bilateral, and can occur in various frequencies. EFDs are typically assessed in the context of a comprehensive neurological evaluation, which may include a physical examination, medical history, and imaging studies.

The clinical significance of EFDs is not entirely understood and is a topic of ongoing research. While some EFDs may be associated with seizures or other neurological disorders, not all EFDs are clinically meaningful. Therefore, it is essential to interpret EFDs in the context of the individual patient's clinical presentation and other diagnostic findings. The electroencephalographer or clinical neurophysiologist is usually responsible for interpreting the EEG and discussing the results with the patient's healthcare provider.
