Circadian and ultradian patterns of epileptiform discharges differ by seizure‐onset location during long‐term ambulatory intracranial monitoring

DC Spencer, FT Sun, SN Brown, BC Jobst… - …, 2016 - Wiley Online Library
Objective Previous studies reporting circadian patterns of epileptiform activity and seizures
are limited by (1) short‐term recording in an epilepsy monitoring unit (EMU) with altered …

How to assess circadian rhythm in humans: a review of literature

WA Hofstra, AW De Weerd - Epilepsy & behavior, 2008 - Elsevier
It is well known that seizures of some types of epilepsy tend to occur in patterns. The
circadian rhythm may play a significant role in this phenomenon. In animal studies it has …

Significance of spikes at temporal lobe electrocorticography

O Kanazawa, WT Blume, JP Girvin - Epilepsia, 1996 - Wiley Online Library
Among 87 consecutive patients operated on under local anesthesia, few aspects of pre‐and
posttemporal lobe resection electrocorticograms (ECoG) yielded prognostic data …

Cortical location of benign paroxysmal rhythms in the electrocorticogram

RS McLachlan, N Lubus - Canadian journal of neurological sciences, 2002 - cambridge.org
Background: Six/second spike waves, 14 and 6/second positive spikes and small sharp
spikes are apiculate paroxysmal rhythms in the electroencephalogram, thought to be of no …

Is there a circadian variation of epileptiform abnormalities in idiopathic generalized epilepsy?

MK Pavlova, SA Shea, FAJL Scheer, EB Bromfield - Epilepsy & Behavior, 2009 - Elsevier
Epileptiform abnormalities often occur at specific times of day or night, possibly attributable
to state of consciousness (sleep vs. wake) and/or influences from the endogenous circadian …

Circadian rhythms: interactions with seizures and epilepsy

M Quigg - Epilepsy research, 2000 - Elsevier
Circadian rhythms are endogenously-mediated 24 h cycles of behavioral or physiological
activity. The interactions among the mammalian circadian clock, acute seizures, and chronic …

Temporal distribution of partial seizures: comparison of an animal model with human partial epilepsy

M Quigg, M Straume, M Menaker… - Annals of …, 1998 - Wiley Online Library
Seizures do not often strike randomly but may occur in circadian patterns. We compared
daily times of partial seizures determined by continuous electroencephalography among …

Day/night patterns of focal seizures

MK Pavlova, SA Shea, EB Bromfield - Epilepsy & Behavior, 2004 - Elsevier
Purpose. In many patients with epilepsy seizures occur with a day/night pattern. Our aims
were to compare day/night patterns in seizure frequency among patients with different …

Chronic intracranial recordings after resection for epilepsy reveal a" running down" of epileptiform activity

B Kundu, CM Charlebois, DN Anderson, A Peters… - …, 2023 - Wiley Online Library
We describe an electrical" running down" phenomenon and also a consistent spectral
change (in the aperiodic component of the power spectrum) derived from chronic interictal …

24-hour rhythmicity of seizures in refractory focal epilepsy

H Nzwalo, IM Cordeiro, AC Santos, R Peralta, T Paiva… - Epilepsy & behavior, 2016 - Elsevier
The occurrence of seizures in specific types of epilepsies can follow a 24-hour nonuniform
or nonrandom pattern. We described the 24-hour pattern of clinical seizures in patients with …
