Systems for monitoring brain activity and patient advisory device

A patient advisory device comprising:

• a housing;
• and
• a user interface on the housing comprising:
• a first portion providing system status information including a failure alert indicator that provides an indication that a failure has occurred with the patient advisory device;
• and
• a second portion comprising a brain state indicator that provides a substantially continuous indication of a patient's propensity for a seizure, wherein the brain state indicator indicates:
• when an estimated brain state is a contra-ictal brain state comprising a protected state in which the patient has a risk of transitioning from a non-ictal state to an ictal state within an upcoming time period below a first risk level;
• and
• when the estimated brain state is a pro-ictal brain state comprising a prediction state in which the patient has a risk of transitioning from a non-ictal state to an ictal state within an upcoming time period above a second risk level, wherein the second risk level is higher than the first risk level.

A patient advisory device comprising:

• a communication assembly configured to wirelessly receive a substantially continuously transmitted data signal that is encoded with brain activity data from a detection device disposed to detect a physiological signal from a patient;
• a digital signal processor that executes a plurality of brain activity algorithms on the substantially continuously transmitted data signal to estimate the patient's brain state;
• a brain state indicator that is activated to report the estimated brain state estimated by at least one of the plurality of brain activity algorithms, wherein the brain state indicator indicates:
• when the estimated brain state is a contra-ictal brain state comprising a protected state in which the patient has a low risk of transitioning from a non-ictal state to an ictal state within an upcoming time period is below a first risk level;
• and
• when the estimated brain state is a pro-ictal brain state comprising a prediction state in which the patient has a risk of transitioning from a non-ictal state to an ictal state within an upcoming time period above a second risk level, wherein the second risk level is higher than the first risk level;
• a first status indicator that indicates an operational status of the patient advisory device;
• a second status indicator that indicates an operational status of the detection device;
• and
• a failure alert indicator that provides an indication that a failure has occurred with the patient advisory device or the detection device.
