Cognilum is intended to reduce symptoms of autism. It is a data-device integrated system, consisting of two parts: Part 1. A wearable physical device, intended to be worn on a child’s head daily, which will (a) provide transcranial photobiomodulation therapy (tPBM) for reduction of symptoms of ASD and (b) collect physical measurements, such as EEG data. Part 2. An intelligent software platform. The platform will collect and analyze data from both the physical device (providing a continuous feedback loop) as well as parental reports of child’s observable behavior and symptoms. The platform evaluates the efficacy of the intervention provided by tPBM as well as other interventions. With sufficient data and analysis using machine learning, it will make predictions about each child’s developmental trajectory and suggest treatment personalization.
