Objective: We investigated quantitative electroencephalography (qEEG) and clinical parameters as potential risk factors of severe cognitive decline in Parkinson's disease. Methods: We prospectively investigated 37 patients with Parkinson's disease at baseline and follow-up (after 3 years). Patients had no severe cognitive impairment at baseline. We used a summary score of cognitive tests as the...

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...

In order to examine the neuropsychological effects of hostility on emotional and pain processing, auditory emotion perception before and after cold pressor pain in high and low hostile men was examined. Additionally, quantitative electroencephalography (QEEG) was recorded between each experimental manipulation. Results indicated that identification of emotion post cold pressor differed as a fun...

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...

Objectives: To study the relationship between magnetic resonance imaging (MRI) T2 relaxation time and the power spectrum of the electroencephalogram (EEG) in long-term follow up of traumatic brain injury. Methods: Nineteen channel quantitative electroencephalograms or qEEG, tests of cognitive function and quantitative MRI T2 relaxation times (qMRI) were measured in 18 mild to severe closed head...

OBJECTIVE It has been proposed that 50%-75% of the efficacy of antidepressant medication represents the placebo effect, since many depressed patients improve when treated with either medication or placebo. This study examined brain function in depressed subjects receiving either active medication or placebo and sought to determine whether quantitative electroencephalography (QEEG) could detect ...

OBJECTIVE To investigate which single quantitative electro-encephalographic (QEEG) marker or which combination of markers correlates best with Alzheimer's disease (AD) severity as measured by the Mini-Mental State Examination (MMSE). METHODS We compared quantitative EEG markers for slowing (relative band powers), synchrony (coherence, canonical correlation, Granger causality) and complexity (...

Neuroplasticity is the ability of brain to change structurally and functionally in compensation for changes related age or disease. In elderly people, most common neuroplasticity problem mild cognitive impairment (MCI). MCI a syndrome defined as decrease function that not appropriate person's educational level. One way minimize progress deterioration by doing physical exercise, such walking. th...

Posterior circulation cerebral infarction (PCCI) can lead to deceased infratentorial blood flow (CBF) and metabolism. Neural activity is closely related regional both spatially temporally. Transcranial Doppler (TCD) combined with quantitative electroencephalography (QEEG) a technique that evaluates neurovascular coupling involves synergy between the metabolic vascular systems. This study aimed ...
