1. A stroke detection system comprising:
a sensor device configured to obtain physiological data from a patient, wherein the sensor device comprises a housing and a plurality of electrodes disposed on the housing and the housing is configured to be disposed at a portion of a neck or a head of the patient, and the physiological data comprises electrical brain activity data and electrical heart activity data of the patient sensed via the plurality of electrodes; and
processing circuitry configured to:
determine that instructions were output to the patient that instruct the patient to perform one or more actions;
receive, from the sensor device, at least a portion of the physiological data during an attempt by the patient to perform the one or more actions;
analyze at least the portion of the physiological data during the attempt by the patient to perform the one or more actions to generate a patient stroke indicator; and
based on the analysis, generate the patient stroke indicator,
wherein the patient stroke indicator includes at least one of:
determining whether a patient has suffered a stroke,
determining a risk that a patient will suffer a stroke,
determining a location of a stroke,
providing a confidence score associated with a determination of patient stroke, or
classifying an identified stroke as ischemic or hemorrhagic.
