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 ...

2022年6月13日 · LRDA is associated with a risk of seizure in ~50% of patients, especially nonconvulsive status epilepticus. Seizure risk seems to emerge at frequencies >1.5 Hz (figure below). causes of LRDA & clinical approach. Causes are generally similar to the causes of LPDs.

lateralized rhythmic delta activity (LRDA) were found to be highly associated with acute seizures, 5,6 equivalent to the association found with lateralized periodic discharges (LPDs) in one study. 5 The

2024年8月11日 · Lateralized RDA (LRDA) is more associated with seizure activity. Proper recognition of GRDA and LRDA may be confused with benign etiologies of RDA like phi rhythm, slow alpha variant, subclinical rhythmic electrographic discharges of adults, or hyperventilation-induced high-amplitude rhythmic slowing.

Our study shows that LRDA is a common EEG pattern in critically ill patients. In this group, it indicates the presence of an epileptogenic brain lesion, most often involving the cortex or the juxtacortical white matter.

2023年6月25日 · The ictal-interictal continuum (IIC) refers to any rhythmic or periodic electroencephalographic (EEG) pattern with features concerning an ongoing seizure but not meeting formal electrographic criteria to be definitively characterized as ictal.

Introduction: Lateralized rhythmic delta activity (LRDA) is a rare pattern on the ictal-interictal continuum (IIC) encountered in critically ill patients. Its association with acute seizures is yet to be fully explored. Insular involvement is a common finding …

2024年5月23日 · We developed an interpretable deep-learning system that accurately classifies six patterns of potentially harmful EEG activity — seizure, lateralized periodic discharges (LPDs), generalized...

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.

2023年7月1日 · Patients with LRDA-ba had a higher proportion of acute focal abnormalities compared with a matched group of patients with GRDA. The LRDA-ba was associated with additional evidence of focal cortical excitability on EEG (sporadic epileptiform discharges and lateralized periodic discharges) and seizure …
