Abstract
An example method for estimating a disease state for a patient can include: capturing physiological data including images from the patient over time; processing the physiological data to detect a variability; comparing the variability to a baseline or a range; and estimating the disease state for the patient based upon the comparing of the variability to the baseline or the limit.
Claims10

- detecting a pupil of the patient;
- capturing images of the pupil over time;
- processing the images to estimate a pupil diameter variability;
- and
- creating a spectrogram of the pupil diameter variability over time.
