“…[25][26][27] In addition, neurofeedback has been successfully introduced in clinical practice to reduce progression of cognitive dysfunction in patients diagnosed with cognitive problems and dementia. [28][29][30][31] The QEEG findings of increased frontal/temporal delta and theta powers in an early dementia patient correlates well with evidence of decreased metabolism in the same regions identified on PET imaging. However, as we know QEEG testing is less expensive and does not require the injection of a radioactive tracer.…”

Quantitative electroencephalography (QEEG)-electrical neuroimaging has been underutilized in general neurology practice. Recent advances in computer technology have made this electrophysiological testing relatively inexpensive as well as precise in identifying brain areas with electrical dysfunction related to either traumatic injury or neurodegenerative process. In this article, the author presents 2 cases that can be frequently encountered in every general neurological practice: case of early dementia and traumatic brain injury. The clinical usefulness of QEEG is demonstrated by showing evidence of electrical abnormalities and networks dysfunctions (including an elevation of frontal/temporal delta and theta powers as well as abnormalities in functional connectivity). In addition, the correlation of QEEG and findings from structural imaging technique—magnetic resonance imaging diffusion tensor imaging and another functional imaging—positron emission tomography is presented.

“…The z-score for a particular QEEG parameter represents the number of standard deviations from the age-normed mean, and participants are trained to approach z = 0. Although few high-quality studies currently exist for the use of z-score NFB (R. Coben et al, 2019), a number of published studies show promising results of z-score NFB for a variety of conditions (Thatcher et al, 2020), including ADHD (Groeneveld et al, 2019;, pain perception (Prinsloo et al, 2018), and cognitive dysfunction (Koberda, 2014). HRV refers to the variability in timing between heart beats (De Jong & Randall, 2005), and it is governed by both the sympathetic and parasympathetic nervous systems.…”

Background: The three-month, multidomain Memory Boot Camp program incorporates z-score neurofeedback (NFB), heart rate variability (HRV) biofeedback, and one-on-one coaching to teach memory skills and encourage behavior change in diet, sleep, physical fitness, and stress reduction. Objective: This prospective trial evaluates the Memory Boot Camp program for adults ages 55 to 85 with symptoms of Mild Cognitive Impairment (MCI) and subjective memory complaints. Methods: Participants were evaluated via the Montreal Cognitive Assessment (MoCA), NeuroTrax Global Cognitive Index, measures of anxiety, depression, sleep, quality of life, quantitative electroencephalography (QEEG), and HRV parameters at four timepoints: baseline, pre-program, post-program, and follow-up. The trial included a three-month waiting period between baseline and pre-program, such that each participant acted as their own control, and follow-up took place six months after completion of the program. Results: Participants’ MoCA scores and self-reported measures of anxiety, depression, sleep quality, and quality of life improved after treatment, and these changes were maintained at follow-up. Physiological changes in HRV parameters after treatment were not significant, however, breathing rate and QEEG parameters were improved at post-program and maintained at follow-up. Finally, participants’ improvement in MoCA score over the treatment period was correlated with their improvement in two brain oscillation parameters targeted by the z-score NFB protocol: relative power of delta and relative power of theta. Conclusions: Trial results suggest that the Memory Boot Camp program is a promising treatment strategy for older adults with symptoms of MCI and subjective memory complaints.

Quantitative EEG Neurometric Analysis–Guided Neurofeedback Treatment in Dementia

Dementia is a debilitating degenerative disorder where the sufferer's cognitive abilities decline over time, depending on the type of dementia. The more common types of dementia include Alzheimer's disease and vascular or multi-infarct dementia. In this study, 20 subjects with dementia (9 of Alzheimer's type, and 11 with vascular dementia) were treated using qEEG-guided neurofeedback training. The Mini Mental Status Examination (MMSE) was used as the primary outcome measure. The results showed an increase of the MMSE scores for all subjects regardless of dementia type with an average MMSE score increase of 6 points, which was found to be significant. To our knowledge this is the first time the same modality was shown to be beneficial in both dementia groups.
