Abstract: Disclosed in some examples are methods, systems, devices, and machine-readable mediums which provide for sidebar communication threads forked from, or related to, a principal thread. Messages in the sidebar communication thread may include a history of the principal thread, including one or more messages from the principal thread, and may include a proposed principal thread message that is the subject of the sidebar thread discussion. The sidebar thread may also include sidebar thread messages that carries the conversation of the sidebar thread participants. Once a termination condition is reached for the sidebar thread, the sidebar thread terminates and either the proposed principal thread message (as potentially modified by participants of the sidebar thread) becomes an accepted principal thread message and it is posted to the principal thread as if it was sent by the sidebar initiator or no message is posted (e.g., the proposed principal thread message is rejected).

Abstract: 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.
