OBJECTIVE Delayed cerebral ischemia (DCI) due to vasospasm is often undetected by clinical exam in patients with poor-grade subarachnoid hemorrhage (SAH). The purpose of this study was to identify quantitative EEG (qEEG) parameters that are most sensitive and specific for the detection of DCI in stuporous or comatose SAH patients. METHODS Of 78 consecutive Hunt-Hess grade 4 or 5 SAH patients ...

BACKGROUND The purpose of this study was to explore the possible difference in the electroencephalogram (EEG) pattern between euglycemia and hypoglycemia in children with type 1 diabetes (T1D) during daytime and during sleep. The aim is to develop a hypoglycemia alarm based on continuous EEG measurement and real-time signal processing. METHOD Eight T1D patients aged 6-12 years were included. ...

Objective: Quantitative electroencephalography (QEEG) is a well established method for evaluating brain functioning. Abnormal oscillatory activity measured with QEEG during resting state has been consistently reported in patients with schizophrenia. We aimed to examine whether resting state EEG is associated with 1 year outcome in patients with first episode psychosis (FEP). Method: Twenty five...

The present study evaluated quantitative electroencephalogram (QEEG)-guided and Scott/Peniston neurofeedback compared with a wait-list control in the treatment of substance abuse in an outpatient setting. Participants completed an intake assessment, 40 neurofeedback sessions, and a posttraining assessment. Change scores of the clinical scales of the Personality Assessment Inventory were used fo...

INTRODUCTION The aim of this study was to build a random forest classifier to improve the diagnostic accuracy in differentiating dementia with Lewy bodies (DLB) from Alzheimer's disease (AD) and to quantify the relevance of multimodal diagnostic measures, with a focus on electroencephalography (EEG). METHODS A total of 66 DLB, 66 AD patients, and 66 controls were selected from the Amsterdam D...

BACKGROUND Successful early detection of mild cognitive impairment (MCI) and Alzheimer's disease demands the identification of biomarkers capable of distinguishing individuals with prodromal or early cognitive impairment from healthy aging adults. Many laboratories are engaged in the discovery and validation of a wide array of potential genetic, proteomic, cognitive, and other types of biomarke...

Although several studies have revealed the EEG alterations in AD and TBI patients, the influence of APOE (apolipoprotein E) genotype in EEG at the early stage of TBI has not been reported yet. We have previously studied EEG alterations caused by TBI among different APOE genotype carriers. In this study, we firstly investigated the relationship between APOE polymorphisms and quantitative EEG (QE...

The study objective was to evaluate the usefulness of Classification and Regression Trees (CART), to classify clinical responders to antidepressant and placebo treatment, utilizing symptom severity and quantitative EEG (QEEG) data. Patients included 51 adults with unipolar depression who completed treatment trials using either fluoxetine, venlafaxine or placebo. Hamilton Depression Rating Scale...

Although tinnitus retraining therapy (TRT) is efficacious in most patients, the exact mechanism is unclear and no predictor of improvement is available. We correlated the extent of improvement with pre-TRT quantitative electroencephalography (qEEG) findings to identify neural predictors of improvement after TRT. Thirty-two patients with debilitating tinnitus were prospectively enrolled, and qEE...

CONTEXT Eye-movement training (EMT) can induce altered brain activation and change the functionality of saccades with changes of the brain in general. OBJECTIVE To determine if EMT would result in changes in quantitative electroencephalogram (qEEG) and NIH Stroke Scale (NIHSS) in patients suffering from acute middle cerebral artery (MCA) infarction. Our hypothesis is that there would be posit...
