The purpose of this study was to analyze the clinical aspects in 130 patients presenting periodic lateralized epileptiform discharges (PLEDs) in their EEG and to compare these results with those found in the literature. Etiology, neurologic deficit, seizure occurrence, and …

Introduced 50 years ago, the term periodic lateralized epileptiform discharge (PLED) (Chatrian et al. 1964) denotes a large (100–300 μV or higher), sharp, and repetitive (usually close to 1 Hz) potential on scalp EEG, usually seen in patients with …

2021年7月1日 · Specific criteria are proposed for Lateralized Periodic Discharges (LPDs) to be designated as “ictal/peri-ictal“ or interictal/irritative brain injury. Identification of peri-ictal LPDs should lead to longer periods of video-EEG monitoring to detect seizure activity.

Periodic lateralized epileptiform discharges (PLEDs) are an electroencephalographic pattern recorded in the setting of a variety of brain abnormalities. It is best recognized for its association with acute viral encephalitis, stroke, tumor, or latestatus epilepticus.

Periodic lateralized epileptiform discharges are a type of EEG abnormality. They are one of the most frequent paroxystic complexes. [1] They are basically triphasic with sharply contoured wave followed by a slow wave mostly occurring unilaterally with duration 100-300 msec and amplitude 100-300 often present with fast rhythm between discharges.

2000年12月1日 · The following report describes the clinical findings and EEG features of a series of 35 patients with multifocal PLEDs occurring independently in 3 or more locations over both hemispheres.

2014年4月8日 · PLEDs in the absence of structural lesion can be ictal, interictal or postictal finding on EEG and resulted in a higher mortality rate. Larger, prospective studies that use neuroimaging as part of a decision tree can provide more definitive guidance.

2021年4月13日 · Conduct a systematic review to identify and compare the risk of seizures in critically ill patients with lateralized rhythmic delta activity (LRDA) and lateralized periodic discharges (LPDs) EEG patterns.

2020年7月31日 · Periodic lateralized epileptiform discharges (PLEDs) are characterized by electroencephalography (EEG) patterns with repetitive spike or sharp wave discharges that are focal or lateralized over one hemisphere and recur at almost fixed time intervals.

Periodic lateralized discharges (PLDs) were studied in 68 patients. Seventy nine percent had seizures, mostly of the partial motor type, and 62 percent showed signs of acute seizure activity. In the majority of cases, localizing signs were present at …
