| Popis: | Background: The treatment of multiple sclerosis implies, beside protecting the body, the preserving of mental functions, considering how adverse cognitive decay affects quality of life. However a cognitive assessment is nowadays still realized with neuro-psychological tests without monitoring cognition on objective neurobiological grounds whereas the ongoing neural activity is in fact readily observable and readable. Objective: The proposed method deciphers electrical brain states which as multi-dimensional cognetoms discriminate quantitatively normal from pathological patterns in the EEG signal. Methods: Baseline recordings from a prior EEG study of 93 subjects, 37 with MS, were analyzed. Spectral bands served to compute cognetoms and categorize subsequent feature combination sets. Results: Using cognetoms and spectral bands, a cross-sectional comparison separated patients from controls with a precision of 82\% while using bands alone arrived at 64\%. A few feature combinations were identified to drive this distinction. Conclusions: Brain states analysis distinguishes successfully controls from patients with MS. Our results imply that this data-driven cross-sectional comparison of EEG data may complement customary diagnostic methods in neurology and psychiatry. However, thinking ahead in terms of quantitative monitoring of disease time course and treatment efficacy, we hope having established the analytic principles applicable to longitudinal clinical studies.
