Abstract

PurposeSeveral studies have indicated that electroencephalography (EEG) and microstates analysis are promising in the attention-deficit hyperactivity disorder (ADHD) diagnosis. However, these studies are restricted to analyzing the temporal dynamics of microstates; therefore, the syntax of symbolic microstates sequences in ADHD patients has not been explored. To solve this gap, this paper proposes a new methodology for the detection of ADHD using EEG microstate analysis and natural language processing.MethodThis method enables to capture the contextual information of symbolic microstates sequence using Word2vec and model each microstate as a numerical vector. The characteristics derived from these embedding vectors were used to train a neural artificial network to classify patients with ADHD and subtypes.ResultsThe proposed method was able to classify ADHD patients with mean accuracy of 99.06% and was also able to identify ADHD subtypes with mean accuracy of 95.56%. In addition, the proposed approach was able to identify and visualize the most relevant symbolic microstates context becoming a useful tool in ADHD diagnosis.ConclusionThe results indicate that contextual features of symbolic microstates sequence captured by Word2vec achieve better classification results when compared to classical microstates analysis and theta to beta ratio (TBR) frequency analysis. Then, the proposed method is promising to identify ADHD and subtypes.
