Effects of the Duration of a Resting-State EEG Recording in Healthy Aging and Mild Cognitive Impairment Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-12-28 Farooq Kamal; Kenneth Campbell; Vanessa Taler
Introduction The recording of resting-state EEG may provide a means to predict early cognitive decline associated with mild cognitive impairment (MCI). Previous studies have typically used very short recording times to avoid a confound with drowsiness that may occur in longer recordings. The effects of a longer recording have not however been systematically examined. Methods Eyes-closed resting-state

Objective Assessments in Diagnoses and Treatment: A Proposed Change in Paradigm Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-12-28 Lukasz M. Konopka; Alice Glowacki; Christian J. Konopka; Ronald Wuest
For patients with psychiatric disorders, current diagnostic and treatment approaches are far from optimal. The clinical interview drives the standard approach—matching symptoms to diagnostic criteria—and results in standardized pharmacological and behavioral treatments, often, with inadequate outcome; but now, recent imaging advances can correlate behavioral assessments with brain function and measure

How can the stability of a recently acquired memory be improved? Recent findings regarding the importance of theta frequency EEG activity in the hippocampus suggest that entraining neural activity in that frequency band might increase post-encoding waking replay, reinforcing learning-related plasticity. Our previous studies revealed that upregulating postlearning theta power using EEG neurofeedback

Efficacy and Safety of Ketamine in Refractory/Super-refractory Nonconvulsive Status Epilepticus: Single-Center Experience. Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-08-05 Nese Dericioglu,Doruk Arslan,Ethem Murat Arsava,Mehmet Akif Topcuoglu
Refractory/super-refractory nonconvulsive status epilepticus (r/srNCSE) is an acute life-threatening neurocritical entity with significant morbidity. Failure to control SE in its earlier stages leads to multiple molecular alterations in the brain such as downregulation of GABA-A and upregulation of NMDA receptors. Recently ketamine, an NMDA receptor antagonist, has gained increased attention as a therapeutic

Active and Passive Attentional Processing in Adolescent Suicide Attempters: An Event-Related Potential Study. Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-06-24 Paniz Tavakoli,Addo Boafo,Emily Jerome,Kenneth Campbell
Introduction: Suicide is the second leading cause of death among adolescents. Suicidal behavior is associated with impairments in attention. Attention can be directed toward relevant events in the environment either actively, under voluntary control, or passively, by external salient events. The extent to which the risk for suicidal behavior affects active and passive attention is largely unknown.

Children with attention deficit hyperactivity disorder (ADHD) have high theta and low beta activity in the frontal lobe. The higher the theta/beta ratio, the lower the level of central nervous system (CNS) cortical arousal. However, there is seldom evidence between electroencephalograms (EEGs) and the patient’s intentionality to regulate the cortical activity of executive attention tasks. We investigated

Evidence From Meta-Analysis Supports Ictal Magnetoencephalographic Source Imaging as an Accurate Method in Presurgery Evaluation of Patients With Drug-Resistant Epilepsy. Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-05-21 Malthe Brændholt,Mads Jensen
BACKGROUND. Successful epilepsy surgery relies on localization and removal of the brain area responsible for initializing the seizures called the epileptogenic zone (EZ). Intracranial EEG (icEEG) is gold standard of this localization but has several limitations like invasiveness and limited covered area. A noninvasive method with accurate localization precision is therefore desirable. The aim of this

Clinical Correlates of Frontal Intermittent Rhythmic Delta Activity Without Structural Brain Lesion. Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-05-15 Keun Tae Kim,Young-Nam Roh,Nan Hee Cho,Jae Cheon Jeon
Frontal intermittent rhythmic delta activity (FIRDA), rhythmic slow wave pattern lasting several seconds over the anterior leads of electroencephalography (EEG), has been reported in a wide variety of clinical conditions. We investigated the clinical significance of FIRDA without structural brain lesions. We reviewed 7689 EEGs between October 2017 and September 2019 at a university hospital. Patients

A Longitudinal, Prospective Study to Evaluate the Effects of Treatment on the Inhibitory Control Function After Transsphenoidal Surgery for Pituitary Adenomas. Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-05-15 Chenglong Cao,Jian Song,Pan Lin,Deqi Yan,Shun Yao,Jianren Yue,Binbin Liu,Yuzhao Lu,Guozheng Xu
OBJECTIVES Injured cognitive abilities have been reported in patients with pituitary adenoma. However, to date, few researchers have directly investigated the electrophysiological study of inhibitory control function of pituitary patients both pre- and postsurgery. Thus, this study aimed to identify the factors affecting the inhibitory control function of pituitary patients. METHODS Thirty presurgery

Generalized Periodic Discharges With Triphasic Morphology in the Setting of Aztreonam Neurotoxicity. Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-05-13 Andrew Billnitzer,Peter W Kaplan
Generalized periodic discharges with triphasic morphology (GPDs + TWm) have been reported with multiple metabolic and drug toxicities. Beta-lactam antibiotics in some cases can cause neurotoxicity with GPDs + TWm on EEG. There are no reports in the literature of aztreonam causing neurotoxicity and GPDs + TWm. Here we describe GPDs + TWm and encephalopathy developing in a patient with underlying dementia

QEEG as a Useful Tool for the Evaluation of Early Cognitive Changes in Dementia and Traumatic Brain Injury. Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-05-11 J Lucas Koberda
Quantitative electroencephalography (QEEG)-electrical neuroimaging has been underutilized in general neurology practice. Recent advances in computer technology have made this electrophysiological testing relatively inexpensive as well as precise in identifying brain areas with electrical dysfunction related to either traumatic injury or neurodegenerative process. In this article, the author presents

Brain Activation Imaging in Emotional Decision Making and Mental Health: A Review-Part 1. Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-05-07 Ronald J Bonnstetter,Thomas F Collura
In part 1 of this article, we describe an approach and methodology that bridges 2 worlds: the internal, subjective experience of emotions and thoughts, and the external world of brain electrical activity. Using a novel event-related brain activation imaging method, we demonstrate that within single trials, short-term mental processes, on the order of 100 ms, can be clearly related to observed brain

Quantitative EEG Findings in Patients With Psychogenic Nonepileptic Seizures. Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-05-04 Kemal Arıkan,Özden Öksüz,Barış Metin,Güven Günver,Hamide Laçin Çetin,Taha Esmeray,Nevzat Tarhan
Objective. Psychogenic nonepileptic seizures (PNES), is one of the clinical manifestations of conversion disorder that epileptiform discharges do not accompany. Factors capable of increasing susceptibility to these seizures have not been adequately investigated yet. This study aims to investigate the quantitative electroencephalography (QEEG) findings for PNES by evaluating the resting EEG spectral

Brain Activation Imaging in Emotional Decision Making and Mental Health: A Review-Part 2. Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-05-03 Thomas F Collura,Ronald J Bonnstetter
In this report, we integrate the principles described in part 1 and describe an operational model for emotional decision making that incorporates brain activation data along with subjective experience correlates. This model takes the form of a state machine that carries out transitions between a finite set of 16 possible states of emotional and decision-making response. By considering a 4 × 4 grid

MMN-Indexed Auditory Change Detection in Major Depressive Disorder. Clin. EEG Neurosci. (IF 1.765) Pub Date : 2020-04-28 Jenna N Bissonnette,Ashley M Francis,Krista M Hull,Jennifer Leckey,Laura Pimer,Lindsay I Berrigan,Derek J Fisher
In major depressive disorder (MDD), event-related potentials that are involved in auditory cortex function (i.e. N100 and P300) often have greater latencies and decreased amplitudes. The auditory mismatch negativity (MMN) is thought to be produced by generators in the auditory cortex, as well as the frontal lobes. Reports on differences in MMN in those with MDD have been varied. It was hypothesized
