摘要
A headset, configured to be attached to a human head, includes an accelerometer providing a signal indicative of head acceleration due to blood flow through the brain. An analyzer evaluates a plurality of samples indicative of acceleration over time where each sample corresponds to the head movement resulting from a cardiac contraction. The analyzer identifies brain conditions at least partially based on a level of chaos of the plurality samples. The algorithm applied by the analyzer is partially formulated based on clinical data and examination of a plurality of subjects. In one example, the plurality of samples evaluated by the analyzer are indicative of the head accelerometer only in a single axis. In some situations, the analyzer identifies brain conditions further based on contemporaneous neurological examination of the subject.
