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.

2022年6月13日 · LPDs are usually caused by acute/subacute, ipsilateral structural brain lesions. LPDs usually resolve after 8-10 days, rarely persisting beyond a few weeks. However, LPDs may occasionally occur due to chronic pathology (e.g., as a postictal feature, or acute reactivation of an underlying chronic structural lesion).

Synonyme: PLED (Periodic lateralized epileptiform discharges) +F: superimposed fast activity. +R: superimposed rhythmic or quasi-rhythmic activity. +FR: superimposed fast activity and rhythmic or quasi-rhythmic activity. LPD's left parieto occipital in a male of 78 years old with a hemmorrhage left occipital (average) Notes.

2021年4月13日 · LPDs and LRDA are EEG patterns usually seen in critically ill ICU patients and associated with structural brain lesions such as intracranial and subarachnoid hemorrhage, encephalitis and tumors. It is well known that LPDs are associated with increased risk of seizures; however, LRDA is a newer term which was first studied and published in 2013 ...

LPDs-max include periodic polyspike-wave activity and/or focal burst-suppression-like patterns. LPDs-max have a posterior predominance over the temporo-parieto-occipital regions and are refractory to antiseizure drugs. Interpretations of EEGs in critically ill patients require a global clinical approach, not limited to the EEG patterns.

2020年10月1日 · LPDs are an EEG pattern indicative of an acute (or less often subacute) non-specific brain injury, which can be accompanied by seizures (Andraus et al., 2012), and are generally associated with poor prognosis, particularly in patients with neoplasms (Lee, 2012).

2022年10月5日 · In a large, multicenter study of 4772 consecutive critically ill adult patients undergoing continuous EEG monitoring, LPDs were associated with the highest risk of seizures, whereas generalized periodic discharges (GPDs) had a lesser risk with no association when frequencies were lower than 1.5 Hz . Lateralized rhythmic delta activity was ...

LPDs are highly associated with NCS on continuous EEG. Ruiz et al. 44% of 802 cEEG with LPDs contained electrographic seizures, the majority of which were nonconvulsive. Of all periodic or rhythmic patterns, LPDs had the highest association with seizures. LPDs+ significantly increased the risk.

The purpose of this article is to provide a comprehensive review of the literature about a particular EEG pattern, lateralized periodic discharges (LPDs), or periodic lateralized epileptiform discharges (PLEDs).

In this paper, an efficient simple system for classifying electroencephalogram (EEG) data of normal and epileptic subjects is presented using lagged Poincare plot parameters. To this effect, a...
