What do PLEDS stand for in EEG terminology?

In EEG terminology, PLEDS stands for Periodic Lateralized Epileptiform Discharges. This term refers to a specific type of EEG pattern characterized by sharp waves or spikes that occur in a periodic and lateralized manner, typically found in one hemisphere of the brain. They are often observed in patients with certain neurological conditions, such as structural brain lesions or during the postictal state following seizures.

The recognition of PLEDS is clinically significant, as it can indicate underlying pathologies, such as tumors, strokes, or other focal brain abnormalities. Understanding the characteristics of these discharges helps clinicians in diagnosing conditions and planning appropriate treatment strategies. The frequency and lateralization of these discharges can provide important information regarding the underlying brain activity and its clinical implications.
