“…The importance of information derived from the QEEG for discriminating various groups of psychiatric patients from one another is less well established, although promising results have been reported (25,60). QEEG has been reported to distinguish between specific groups of neurologic and psychiatric patients with high accuracy, to predict cognitive performance and cognitive decline in elderly populations, to show characteristic patterns of abnormality in subjects with crack cocaine dependence, and to be a sensitive indicator of cortical damage after head injury (25,26,61,62). A recent report has indicated that QEEG can be a useful adjunct in clinical psychiatry (63).…”

“…This technique utilizes parametric statistics to compare EEG measures obtained from an individual patient with those obtained from an ageregressed database of normal individuals, and is free of cultural and ethnic bias (21)(22)(23). QEEG has been shown to be a sensitive indicator of cortical electrophysiologic dysfunction in patients with a diverse range of neurologic and psychiatric disorders (24)(25)(26). The purpose of the present study was to determine the utility of QEEG for the diagnosis and treatment of NPSLE.…”

Objective. Neuropsychiatric manifestations are common in patients with systemic lupus erythematosus (SLE), but accurate diagnosis is often difficult. We conducted a prospective study to determine the utility of neurometric quantitative electroencephalography (QEEG) as an indicator of cerebral dysfunction in SLE patients. Methods. Fifty-two SLE patients were divided into 4 groups based on the results of neuropsychiatric evaluations. These included patients with objective evidence of neuropsychiatric SLE (NPSLE), patients with neuropsychiatric symptoms, patients with no evidence of NPSLE, and patients with a prior history of NPSLE. All QEEG findings were compared with data in an age-regressed normative database and with findings in an independent sample of normal subjects.Results. QEEG sensitivity was 87%, and specificity was 75%. QEEG results were abnormal in 74% of the SLE patients with neuropsychiatric symptoms and in 28% of the patients with no evidence of active NPSLE. QEEG profiles varied as a function of the severity and type of neuropsychiatric manifestation present. Within this patient population, QEEG was more sensitive than magnetic resonance imaging, computed tomography scanning, or conventional EEG.Conclusion. Neurometric QEEG may be a sensitive indicator of cerebral dysfunction in patients with NPSLE and can differentiate patients with diverse neuropsychiatric manifestations. When combined with a careful clinical history and evaluation, QEEG provides information that may be useful for the early detection of NPSLE and for serial evaluation of disease activity and treatment efficacy.Neurologic and psychiatric manifestations of systemic lupus erythematosus (SLE) are common, occurring at any time during the illness, and often in the absence of generalized disease activity. Estimates of the prevalence of neuropsychiatric SLE (NPSLE) vary between 24% and 75% (1-7). This variability is partially due to the lack of uniform diagnostic criteria for determining central nervous system (CNS) involve-

“…Specific patterns of qEEG abnormality associated with specific substance use toxicity such as those found in stimulant abuse or alcohol abuse or with comorbidities such as ADHD (Chabot & Serfontein, 1996), PTSD (Huang-Storms et al, 2006) or TBI (Thatcher, Walker, Gerson, & Geisler, 1989) suggest underlying brain pathologies that might be amenable to EEG biofeedback that is tailored to the person. These approaches would likely be individualized rather than protocol based and would be used independently or in conjunction with classic alpha-theta training.…”

“…For example, approximately 15 to 40% of moderate to severe CHI patients exhibited visually detectable pathology in the MRI, while in autopsy, microscopic examinations of these same patients demonstrated that approximately 90% of patients have gray matter contusions as well as shear force injuries diffusely located within the cortical gray and white matter (Gentry, 1990(Gentry, , 1994Gentry et al, 1988). In contrast to visual examination of the MRI, computerized electroencephalography referred to as QEEG has been shown to be greater than 90% accurate in the detection of even mild CHI (Thatcher et al, 1989. However a weakness of QEEG is the lack of physiological and anatomical specificity because many changes in the chemistry and physiology of neurons and glia can affect the EEG power spectrum (Nunez, 1981(Nunez, , 1995Lopes da Silva, 1991).…”
