A system and method for capturing and analyzing a person's behavioral functions (e.g., 3-D bodily movements, facial expressions, vocalizations), and for developing a corresponding personal behavioral signature. The capture may be performed passively, e.g., in contactless manner (e.g., using LIDAR or camera-based imaging, and/or a microphone). Artificial intelligence, machine learning, and/or other techniques to may be used to analyze captured behavioral function data to identify patterns, assess characteristics, etc., and develop the corresponding behavioral signature. A baseline signature may be compared to a subsequent signature to assess a change in behavioral state. Similarly, data and/or signatures for multiple individuals having a common disease (or receiving a common treatment) may be analyzed to develop a characteristic disease signature (or treatment signature). A person's behavioral signature may be compared to pre-defined disease signatures (or treatment signatures) to identify whether the person has the disease (or is responding appropriately to the treatment).
