Ultrafast oscillations in the human brain and their functional significance

Epilepsia, EarlyView.
Abstract Objective The upper frequency limit of human brain activity remains unknown. Using ultrahigh sampling rate (≥20 kHz) intracranial microelectroencephalography, this study aimed to systematically explore and quantitatively characterize brain field oscillations beyond the established high‐frequency oscillation range (>2 kHz), and to determine ...

Regional thalamic neuropathology in patients with hippocampal sclerosis and epilepsy: A postmortem study [PDF]

, 2013
Purpose Clinical, experimental, and neuroimaging data all indicate that the thalamus is involved in the network of changes associated with temporal lobe epilepsy (TLE), particularly in association with hippocampal sclerosis (HS), with potential roles in ...

Comparison of volume‐ and surface‐based magnetic resonance imaging morphometry algorithms in the detection of focal cortical dysplasia

Epilepsia, EarlyView.
Abstract Objective Detection of focal cortical dysplasia (FCD) remains a major challenge in presurgical epilepsy diagnostics. Magnetic resonance imaging (MRI) morphometry increasingly improves lesion detection and postsurgical outcomes. The volume‐based Morphometric Analysis Program, version 2018 (MAP18) with integrated artificial neural network and ...

Mindfulness meditation increases interictal epileptiform discharges in meditation‐naïve surgical epilepsy patients

Epilepsia, EarlyView.
Abstract Objective Meditation has widely recognized psychological and neuromodulatory benefits, yet its effects on epileptiform activity remain unclear. This study examined whether novice meditation modulates interictal epileptiform discharges (IEDs) in patients with drug‐resistant epilepsy using intracranial electroencephalography (iEEG).

Paroxysmal slow waves mark ictal networks

Epilepsia, EarlyView.
Abstract Objective Epilepsy diagnosis and treatment monitoring are hindered by the episodic, heterogeneous expression of seizures and by normal‐appearing scalp electroencephalography (EEG) in many patients. We previously described paroxysmal slow‐wave events (PSWEs), brief epochs of broadband slowing detectable on EEG in people with epilepsy.

The dynamic functional connectivity peak index: Detection of interictal epileptic activity with fMRI

Epilepsia, EarlyView.
Abstract Objective Epileptogenic zone (EZ) localization is crucial for surgical treatment of patients with medication‐resistant epilepsy. Although simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) can detect interictal discharges for EZ localization, clinical adoption is limited by the need for specialized ...

Gamma suppression correlates with thalamic stimulation therapeutic response in intractable epilepsy

Epilepsia, EarlyView.
Abstract Objective In patients with drug‐resistant epilepsy who undergo anterior nucleus of the thalamus (ANT) deep brain stimulation (DBS), efficacy is assessed months after therapy initiation and clinicians have no guidance when choosing stimulation parameters due to the lack of real‐time biomarkers.

Intermittent fasting with medium‐chain triglycerides in drug‐resistant epilepsy: A pilot crossover trial

Epilepsia, EarlyView.
Abstract Objective Ketogenic dietary therapies can reduce seizure frequency in drug‐resistant epilepsy, but adherence to the classical ketogenic diet is often poor. Intermittent fasting supplemented with medium‐chain triglycerides (MCTs) may offer a more feasible and less restrictive alternative.

Complementary predictive value of electromagnetic source imaging and hemodynamic responses in epilepsy surgery: A quantitative spatial analysis

Epilepsia, EarlyView.
Abstract Objective Accurate presurgical evaluation should assess not only the location but also the spatial extent of epileptic activity relative to the surgical cavity, a practical approximation of the epileptogenic zone. We evaluated how electromagnetic source imaging (EMSI) and hemodynamic responses to epileptic discharges relate to the surgical ...
