1. A system comprising:
a sensor device comprising:
a housing configured to be disposed above shoulders of a patient;
a plurality of electrodes configured to be disposed above the shoulders of the patient;
a motion sensor within the housing; and
sensing circuitry within the housing, the sensing circuitry configured to:
sense, via the plurality of electrodes configured to be disposed above the shoulders of the patient, a brain signal and a cardiac signal of the patient; and
sense, via the motion sensor configured to be disposed above the shoulders of the patient, a motion signal of the patient; and
processing circuitry configured to:
determine values over time of one or more parameters from the brain signal;
determine values over time of one or more parameters from the cardiac signal;
generate at least one of a detection, prediction, or classification of a condition of the patient based on the values over time of the one or more parameters from the brain signal, the values over time of the one or more one or more parameters from the cardiac signal, and the motion signal, wherein the condition comprises a stroke or a seizure; and
output an indication of the at least one of a detection, prediction, or classification to a computing device.
