2022年6月13日 · (2) Some studies have found that LPDs correlated with glucose hypermetabolism seen on PET scans. LPDs >2 Hz have been associated with focal tissue …

2021年7月1日 · We propose LPDs with a periodicity greater than 1 Hz are associated with ictal or peri-ictal patterns, whereas a periodicity of 0.5 Hz or less is associated with interictal/irritative …

2022年10月5日 · The risk of seizures increases when the frequency of periodic discharges exceeds 2 Hz and when the pattern has features of superimposed rhythmic, sharp, or fast …

2020年7月8日 · LPDs are stereotyped, repetitive EEG discharges and recurr periodically at regular intervals at 0.5 to 3 Hz; they are broadly lateralized over one hemisphere, particularly …

In patients with traumatic brain injury (TBI), periodic patterns > 2 Hz produced metabolic crisis as increased lactate/pyruvate ratio (LPR) and decreased glucose levels in cerebral microdialysate …

a) A robust regular PLED waveform, whose spectrum d) shows a clear 2-peaked structure of a fundamental (at ~0.9 Hz) and its second harmonic (at ~1.8 Hz) along with a small third …

2015年8月1日 · Generalized periodic diacharges or lateralized periodic discharges (GPDs/LPDs) with a frequency of less than 2.5 Hz or rhythmic discharges (RDs) faster than 0.5 Hz are the …

2022年3月15日 · Lateralized periodic discharges (LPDs), formerly known as periodic lateralized epileptiform discharges (PLEDs) were first described by Chatrain et al. as periodic or quasi …

The frequency of LPDs is correlated with seizure risk [23]: LPDs of less than 1 Hz: 40% risk of seizures, LPDs of 2 Hz or greater: 66% risk of seizures. ... View in full-text Context 3

In a prospective study of 90 comatose adults with poor grade subarachnoid hemorrhage, periodic discharges identified at a frequency ≥ 2 Hz were associated with a 25% decrease in PbtO 2 5 …
