Spectral analysis of the electrophysiological output at a single, midline prefrontal location (the vertex) was conducted in 482 individuals, ages 6-30 years old, to test the hypothesis that cortical slowing in the prefrontal region can serve as a basis for differentiating patients with attention deficit hyperactivity disorder (ADHD) from nonclinical control groups. Participants were classified ...

Results from this study indicated that individuals with ADHD could be reliably distinguished from non-ADHD individuals by QEEG scan results of the prefrontal cortical areas. Approximately 90% of individuals who had been carefully diagnosed with ADHD using standard diagnosed procedures showed a pattern of under activity in these areas (referred to as “cortical slowing”). In contrast, 94% of a co...

OBJECTIVE To investigate the use of quantitative EEG (qEEG) in patients with acute encephalopathies (AEs) and EEG background abnormalities. METHOD Patients were divided into favorable outcome (group A, 43 patients) and an unfavorable outcome (group B, 5 patients). EEGLAB software was used for the qEEG analysis. A graphic of the spectral power from all channels was generated for each participa...

Determination of brain dying means reversible or irreversible injury to the brain, including brainstem. Current guidelines rely on clinical examination proof coma, absent stem reflexes, and apnoea test. Neurophysiological testing using electroencephalography evoked potentials — somatosensory brainstem auditory potential could have been helpful in final diagnostic death conclusion, but accuracy t...

This study was conducted in an attempt to determine the efficacy of neurofeedback (NFB) in the treatment of patients suffering from vertigo or tinnitus. Results indicated that after NFB, power for delta and theta bands was reduced; however, an increase of power was noted for the alpha bands. Furthermore, normalization was observed for the vestibular evoked potentials (VestEP). After NFB, a norm...

Abstract Study Objectives Obstructive sleep apnea is highly prevalent, but heterogeneous making identifying patients at risk of driving impairment challenging. Resting wake electroencephalography (qEEG) associated with vigilance performance in healthy subjects. We examined if qEEG and clinical measures predict OSA. Methods Fifty-four underwent baseline PSG 28hr extended wakefulness (EW) 2 hourl...

Complex developmental trauma (CDT) is characterized by prolonged exposure to traumatic events in early life, resulting the breakdown of neurobiological integration which impacts mental and physical health. The benefits practicing short-form improvisation (improv), however, parallel treatment needs this population. To observe effect improv, we used eyes-open quantitative electroencephalography (...

OBJECTIVES Therapeutic hypothermia (TH) after cardiac arrest (CA) improves outcomes in a fraction of patients. To enhance the administration of TH, we studied brain electrophysiological monitoring in determining the benefit of early initiation of TH compared to conventional administration in a rat model. METHODS Using an asphyxial CA model, we compared the benefit of immediate hypothermia (IH...

The therapeutic potential of meditation for physical and mental well-being is well documented, however the possibility of adverse effects warrants further discussion of the suitability of any particular meditation practice for every given participant. This concern highlights the need for a personalized approach in the meditation practice adjusted for a concrete individual. This can be done by u...

The development of a quantitative electroencephalographic (QEEG)-based procedure for use in the assessment of attention deficit-hyperactivity disorder (ADHD) was examined through a series of studies investigating test reliability and validation issues. This process, involving a spectral analysis of the electrophysiological power output from a single, midline, central location (the vertex), was ...
