Firefly Advances Objective Brain-Based ADHD Diagnosis Tools
According to Firefly, the work uses Resting EEG and Cognitive EEG, also known as ERP, to identify potential neural biomarkers tied to hyperactive-impulsive, inattentive and combined ADHD presentations.
The announcement is significant because ADHD is typically diagnosed using symptom-based assessments rather than objective biological tools.
Firefly said its approach could eventually complement traditional checklists with brain-based data, helping clinicians tailor treatment choices, guide dosage decisions and monitor whether a therapy is working at the neurological level.
