Working memory (WM) dysfunction and increased within-subject variability are known issues in attention deficit/hyperactivity disorder (ADHD) patients. Little is known about the electrophysiological characteristics of this variability. We evaluated behavioral and electrophysiological within-subject variability taking developmental aspects into account in a group of ADHD patients. Multichannel (n = 31) event-related potentials (ERP) were measured during a visuo-spatial backmatching task; 44 children (8-16 years old) were tested: 22 children with ADHD, combined (n = 17) and inattentive (n = 5) type, and 22 age- and intelligence-matched control children. One-backmatching (BM1) and two-backmatching (BM2) tasks were performed. Classical behavioral parameters and target and nontarget ERP were compared between groups. In addition, motor response variability and ERP amplitude variability were studied. Age-related changes in both motor response and ERP amplitude variability were analyzed in each group. Attention deficit/hyperactivity disorder children made more commission errors, which was more pronounced in the difficult (BM2) task. No difference between groups was found in ERP amplitude and in motor response variability. However, ADHD patients had higher ERP amplitude variability, which was again more pronounced in the difficult WM task. A delayed maturation of amplitude variability was seen in ADHD patients with a slower than in controls decrease in variability with age. This amplitude variability was correlated with the number of commissions, but in an opposite way for ADHD and control children. Our findings indicate an impaired visuo-spatial WM processing in ADHD children with greater ERP amplitude variability compared to controls. Our results also support the view of a delayed cortical development of visuo-spatial WM circuits in this disorder.

“…In particular the attention problems associated with ADHD have been poorly characterised and are relatively underrepresented in the literature. Two consistent findings in ADHD research have been poor sustained attention [4][5][6] and attenuated electrodermal activity (EDA) [7][8][9]. The importance of EDA as a "somatic marker" for the consequences of different behaviours [10] has been well established in decision-making tasks however it is not clear how somatic markers are related to other executive functions such as, for example, sustained attention [11].…”

“…Zahn, Grafman and Tranel [18] found that rather than directly affecting EDA however, right frontal damage produces a selective impairment of the psychological processing of significant stimuli. A number of studies have examined EDA in ADHD and while no consistent differences in baseline EDA have been found [8], children with ADHD do consistently exhibit reduced electrodermal responsiveness to task-related stimuli [7][8][9] suggesting that ADHD, like frontal pathology, may also involve a selective EDA deficit.…”

Reduced electrodermal response to errors predicts poor sustained attention performance in attention deficit hyperactivity disorder

Research into ADHD has indicated abnormalities in electrodermal system activity (EDA) and separately, deficits in sustained attention. Here we asked for the first time whether reduced EDA in ADHD was consequential for the attention problems associated with this disorder. On a sustained attention task ADHD participants had higher overall error rates and exhibited a marked decrease in skin conductance responses (SCRs) to errors, relative to control children. Further, sustained attention errors were predicted by SCR amplitudes. Evidence of post-error slowing in both groups suggested comparable error awareness. It is proposed that attenuation of the normal autonomic response to errors may impair ADHD participants' psychological response to error significance and result in decreased behavioural correction and poorer sustained attention.

“…The need for more precise and reliable diagnostic markers is underscored by a well established association between the duration of untreated psychosis and an unfavorable clinical outcome of schizophrenia [17][18][19]. Therefore, in addition to the interview and observation of the patient, a biological marker related to the brain dysfunction or brain potentials of schizophrenia may also be useful in determining the clinical diagnosis of schizophrenia [4,16,20,21].…”

“…This method is called exploratory quantum resonance test. Therefore, the above physiological or neuroscience defects, the change of electromagnetic wave signals [3,4] or yin-yang meridian, may show promise as biological markers of schizophrenia [5,6]. The aim of the research was to develop an easily available and replicable biological objective system, Quantum Resonance Spectrometer (QRS), which based on yin-yang meridian, could be used as predictor of psychiatric diagnoses, and could attenuate subjective ratings [7].…”
