The potential neurotoxicity of a compound can be evaluated in various ways. Neurotoxicity screening can be based on a battery of measurements and observations such as the functional observational battery that has been in use for a number of years. This chapter outlines briefly some statistical approaches that may be useful for the evaluation of neurological toxicity, especially as manifested in changes in electroencephalograms (EEG) recordings, in the context of clinical trials. It focuses on methods that can be implemented in a practical way for “routine” evaluation of neurotoxicity assessments obtained in the course of clinical trials. Key issues for EEG analyses include data reduction, accounting for potential correlations across time and among channels, and non-stationarity. EEGs generate a large amount of information and their analysis is complicated. Exploiting this technology for routine evaluation of potential toxicity of new products is currently a major challenge, but progress is being made.

Philosophical Transactions of the Royal Society A: Mathematical Physical and Engineering Sciences, 367, 317–336. Nonlinear methods have been applied to study the EEG and MEG background activity in patients with Alzheimer's disease and control subjects: approximate entropy, sample entropy, multiscale entropy, auto-mutual information, and Lempel–Ziv complexity. The same databases of EEG and MEG recordings were used to compare the performance of these methods. EEG and MEG background activities in patients with Alzheimer's disease turned out to be less complex and more regular than in healthy control subjects, suggesting that nonlinear analysis techniques could be useful in diagnosis of Alzheimer's disease.

Clinical Neurophysiology, 120, 845–855. This paper defines a revised version of van Putten BSI. Suppose M frequencies from Fourier analysis of EEG and N channels, and let R(i,f) and L(i,f) denote power at frequency f for right-hand channel i and left-hand channel i. The modified BSI = average value of |R(i,f-L(i,f/(R(i,f)+L(i,f)). This is applied to the EEGs of 31 patients with subacute ischemic cardiovascular disease and 10 age-matched controls. The modified BSI was sensitive to asymmetry in various models, with good reproducibility, and correlated well with NIH Stroke Scale score. It also could differentiate between patients with stroke and normals or those with transient ischemic attack.

This paper defines an index of bilateral brain symmety. On the basis of a spectral (Fourier) decomposition of an EEG signal, let R(i,f) denote the power at frequency f (assume M such frequencies) for channel i on the right-hand side of the brain and let L(i,f) denote the corresponding power for the left channel. Take the sum of the ratios (R(i,f)-L(i,f)/R(i,f)+L(i,f)) over the channels (which gives M ratio values). Then the Brain Symmetry Index (BSI) is the average of these sums over the collection of M frequencies. The measure was applied to the EEGs of 21 patients, and showed a positive correlation (0.86) between the BSI and the NIH Stroke Scale.

(2011) Addition of EEG improves accuracy of a logistic model that uses neuropsychological and cardiovascular factors to identify dementia and MCI. Psychiatry Research, 186, 97–102. This paper evaluates the improvement in diagnostic properties of a logistic model for identifying dementia and mild cognitive impairment (MCI) in a sample of 111 individuals (78 normal, 33 with dementia or MCI) that was realized by including summary measures obtained from EEG recordings, including power spectrum components and fractal dimension (complexity). Including EEG information (especially complexity) along with information from neuropsychological testing (ADAS-Cog score) and cardiovascular history and risk factors improved the accuracy of the predictions. This was a small study, so its generalizability is limited.

This paper evaluates the pharmacologic effect of a dose of alprazolam on wakeful brain connectivity using linear and nonlinear reductions of EEG signals in a double-blind placebo-controlled crossover trial with nine subjects. Channels were analyzed separately and then compared pairwise. Alprazolam induced changes in EEG connectivity measured using cross-conditional entropy between channels, corresponding to scalp regions.

This paper provides a comprehensive empirical evaluation of the relationship between measures of fractality (Hurst coefficient, range of fractal spectra) and conventional measures (band powers and spectral edge frequencies) calculated from EEGs across different sleep stages and topographic locations based on sleep studies carried out on two successive nights with 22 subjects. Extensive literature citations are given. The key finding is that fractal features provide additional useful information about EEG signals, and that a multifractal approach (range of fractal spectra) may be more helpful for modeling complex brain activities.
