Functional brain changes using electroencephalography after a 24-week multidomain intervention program to prevent dementia

Frontiers in Aging Neuroscience, 2022
Quantitative electroencephalography (QEEG) has proven useful in predicting the response to various treatments, but, until now, no study has investigated changes in functional connectivity using QEEG following a lifestyle intervention program. We aimed to

Quantitative Electroencephalography in Late-Onset Schizophrenia

International Psychogeriatrics, 2003
A variety of electroencephalogram (EEG) abnormalities may occur in schizophrenics who had a typical onset of the disorder in early adulthood. The purpose of this study was to investigate EEG findings in patients with late-onset schizophrenia (onset of illness between ages 40 and 60).Ten patients (one male, nine female, average age 52.8 years old) with ...

Delta Power Is Higher and More Symmetrical in Ischemic Stroke Patients with Cortical Involvement

Frontiers in Human Neuroscience, 2017
A brain injury resulting from unilateral stroke critically alters brain functionality and the complex balance within the cortical activity. Such modifications may critically depend on lesion location and cortical involvement.

Quantitative Pharmaco-Electroencephalography in Antiepileptic Drug Research [PDF]

CNS Drugs, 2018
AbstractPharmaco-electroencephalography (pharmaco-EEG) has never gained great popularity in epilepsy research. Nevertheless, the electroencephalogram (EEG) is the most important neurological examination technique in this patient population. Development and investigation of antiepileptic drugs (AEDs) involves EEG for diagnosis and outcome evaluation. In

Quantitative Electroencephalography After Pediatric Anterior Circulation Stroke

Journal of Clinical Neurophysiology, 2020
Objective: Regional differences were investigated in quantitative EEG (QEEG) characteristics and associations of QEEG to hemodynamics after pediatric acute stroke. Methods: Quantitative EEG was analyzed, including power in delta, theta, alpha, and beta bands, alpha–delta power ratio,
