Publication number: 20240188866Abstract: An early assistive diagnosis system of ADHD provides a test to the subject and uses a brain-computer interface (BCI) to detect the electroencephalography (EEG) signals of subject. A host receives the EEG signals, captures the features associated with ADHD heterogeneities, obtains feature EEG signals, and classifies the subject as typical development or ADHD, then uses the EEG feature signals to train a predicted index score range for the heterogeneities of ADHD. The test scores of a new subject is tested, it is compared whether the scores fall within the predicted index score range to determine the ADHD heterogeneity types to which the new subject belongs. Thus, the present invention uses attention tests for ADHD in combination with EEG signals to assess symptoms of a subject, further predicts the potential aptitude of a subject for ADHD and provides objective assistive diagnosis to physicians.Type: ApplicationFiled: December 7, 2023Publication date: June 13, 2024Applicant: National Yang Ming Chiao Tung UniversityInventors: Li-Wei KO, I-Chun CHEN, I-Wen HUANG, Jo-Wei LIN, Zuo-Cian FAN, Chih-Hao CHANG, Yang CHANG
