A system configured to predict a lucidity level of a subject, the system comprising: one or more activity sensors configured to generate output signals conveying information related to physical activity of the subject; one or more physiological sensors configured to generate output signals conveying information related to physiological parameters of the subject; a user interface configured to receive information related to a mood of the subject and information related to a cognitive state of the subject; and one or more hardware processors configured by machine-readable instructions to: generate an electronic lucidity model for the subject based on previous physical activity information, previous physiological parameter information, previous mood information, and previous cognitive state information; predict the lucidity level of the subject based on the electronic lucidity model and one or more of current physical activity information, current physiological parameter information, current mood information, or current cognitive state information; and communicate the predicted lucidity level to a caregiver of the subject, the communication including an explanation of which current physical activity information, current physiological parameter information, current mood information, and/or current cognitive state information influenced the predicted lucidity level. one or more activity sensors configured to generate output signals conveying information related to physical activity of the subject; one or more physiological sensors configured to generate output signals conveying information related to physiological parameters of the subject; a user interface configured to receive information related to a mood of the subject and information related to a cognitive state of the subject; and one or more hardware processors configured by machine-readable instructions to: generate an electronic lucidity model for the subject based on previous physical activity information, previous physiological parameter information, previous mood information, and previous cognitive state information; predict the lucidity level of the subject based on the electronic lucidity model and one or more of current physical activity information, current physiological parameter information, current mood information, or current cognitive state information; and communicate the predicted lucidity level to a caregiver of the subject, the communication including an explanation of which current physical activity information, current physiological parameter information, current mood information, and/or current cognitive state information influenced the predicted lucidity level. generate an electronic lucidity model for the subject based on previous physical activity information, previous physiological parameter information, previous mood information, and previous cognitive state information; predict the lucidity level of the subject based on the electronic lucidity model and one or more of current physical activity information, current physiological parameter information, current mood information, or current cognitive state information; and communicate the predicted lucidity level to a caregiver of the subject, the communication including an explanation of which current physical activity information, current physiological parameter information, current mood information, and/or current cognitive state information influenced the predicted lucidity level. <EOS>
