Diagnostic automatique de l'autisme: à la recherche d'un marqueur mathématique
Abstract
Abstract Autism is a type of neurodevelopmental disorder
affecting the memory, behavior, emotion, learning ability, and
communication of an individual. An early detection of the abnormality,
due to irregular processing in the brain, can be achieved using
electroencephalograms (EEG). The variations in the EEG signals cannot be
deciphered by mere visual inspection. Computer-aided diagnostic tools
can be used to recognize the subtle and invisible information present in
the irregular EEG pattern and diagnose autism. This paper presents a state-of-the-art review of automated EEG-based diagnosis of autism. Various time domain, frequency domain, time-frequency domain, and nonlinear dynamics for the analysis of autistic
EEG signals are described briefly. A focus of the review is the use of
nonlinear dynamics and chaos theory to discover the mathematical
biomarkers for the diagnosis of the autism
analogous to biological markers. A combination of the time-frequency
and nonlinear dynamic analysis is the most effective approach to
characterize the nonstationary and chaotic physiological signals for the
automated EEG-based diagnosis of autism spectrum disorder (ASD). The features extracted using these nonlinear methods can be used as mathematical markers to detect the early stage of autism and aid the clinicians in their diagnosis. This will expedite the administration of appropriate therapies to treat the disorder.
