Research over the last 30 years has confirmed that excessive slow brainwave activity is the most common finding of electroencephalographic (EEG) abnormalities in children with Attention Deficit Hyperactivity Disorder (ADHD) and Learning difficulties . Quantitative EEG (QEEG) studies have confirmed and extended these findings. In the Early 1970s Prof. Barry Sterman at UCLA and later Prof. Joel L...

Patients suffering from epilepsy commonly experience behavioral symptoms. Behavioral manifestations are especially prevalent in patients with seizures originating in the limbic system. This case report illustrates how an objective, multimodality work-up can guide the clinician in the diagnosis and the treatment of a patient with a complex presentation. After the discontinuation of some medicati...

Caffeine is the most consumed psychoactive substance in the world. The effects of caffeine have been studied using cognitive and motor measures, quantitative electroencephalography (qEEG) and event-related potentials. However, these methods are not usually employed in combination, a fact that impairs the interpretation of the results. The objective of the present study was to analyze changes in...

OBJECTIVE To evaluate the contribution of quantitative electroencephalographic (qEEG) analyses in the diagnosis of Alzheimer's disease (AD). METHOD Thirty-five patients from the Neurology Outpatients Clinic of PUC-Campinas, diagnosed with AD according to the NINCDS/ADRDA were evaluated, and compared with a control group consisting of 30 individuals with no cognitive deficit. The procedures co...

OBJECTIVE The aim of our study is to examine quantitative Electroencephalogram (QEEG) differences between ADHD patients that are responders and non-responders to long-term treatment with Atomoxetine at baseline and after 6 and 12months of treatment. Patients with attention deficit hyperactivity disorder (ADHD) received atomoxetine titrated, over 7days, from 0.5 to 1.2mg/kg/day. QEEG and Swanson...

The following pages represent a summary of many articles, papers, reviews and books on medications and the CNS function, and finally nearly 30 years of experience in clinical and research EEG. The difficulty in this area is the definitions of bands varies, the methods of analysis range from visual inspection of the raw EEG to quantitative measures, not all of which are clearly defined... and th...

OBJECTIVE Mild cognitive impairment in Parkinson's disease (PD-MCI) is diagnosed based on the results of a standardized set of cognitive tests. We investigate whether quantitative EEG (qEEG) measures could identify differences between cognitively normal PD (PD-CogNL) and PD-MCI patients. METHODS High-resolution EEG was recorded in 53 patients with Parkinson's disease (PD). Relative power in f...

-A hardware and software design and development is described for a two-channel portable recording device specifically to collect the electroencephalogram (EEG). The application intended for this device was collection of EEG data from drivers, while driving under controlled conditions on closed roads or circuits. The monitoring of driver reactions may lead to a better understanding of driving ab...

UNLABELLED Anxiety is defined as a subjective sense of worry, apprehension, fear and distress. When severe, it can affect a child's thinking, decision-making ability, perceptions of the environment, learning and concentration. Basal instability in cortical arousal, as reflected in measures of quantitative electroencephalography (qEEG), is common in most of the anxiety disorders. SUBJECTS AND ...
