Digital therapeutics (DTx) represent an emerging investment frontier in neurodegenerative disease, combining software-based interventions with traditional clinical validation[1]. Unlike pharmaceutical interventions, digital therapeutics offer advantages including reduced side effects, continuous patient monitoring, and personalized dosing adjustments[2].
