One variation of a method for characterizing ADHD includes: accessing results of a cognitive evaluation executed by a user; accessing a timeseries of biosignal data collected via sensors worn by the user during execution of the cognitive evaluation; accessing a global model linking results of the cognitive evaluation and biosignal data to cognitive states of users diagnosed with ADHD; and interpreting a confidence score, representing probability of an ADHD diagnosis, based on results of the cognitive evaluation, the timeseries of biosignal data, and the global model. The method further includes, in response to the confidence score exceeding a threshold confidence: selecting a treatment pathway for the user based on results of the cognitive evaluation and the timeseries of biosignal data; and deriving an ADHD model for the user linking biosignal data to cognitive states based on results of the cognitive evaluation, the timeseries of biosignal data, and the global model.
