Patient Advisory Device
First Claim
1. A method of monitoring a patient'"'"'s brain activity, the method comprising:
- sampling a brain activity signal from the patient;
wirelessly transmitting a substantially real-time data signal from a device implanted in the patient'"'"'s body to a patient advisory device external to the patient'"'"'s body, wherein the data signal is encoded with data that is indicative of the sampled brain activity signal;
processing the sampled brain activity signal to assess the patient'"'"'s propensity for a seizure;
providing a first indication with the patient advisory device that is indicative of the patient'"'"'s propensity for the seizure; and
providing a second indication with the patient advisory device of a status of at least one of the patient advisory device and implanted device.

Abstract
A patient advisory device (“PAD”) and its methods of use. The PAD may be configured to alert the patient about an estimated brain state of the patient. In preferred embodiments, the PAD is adapted to alert the patient of the patient'"'"'s brain state, which corresponds to the patient'"'"'s propensity of transitioning into an ictal brain state, e.g., having a seizure. Based on the specific type of alert, the patient will be made aware whether they are highly unlikely to have a seizure for a given period of time, an elevated propensity of having a seizure, a seizure is occurring or imminent, or the patient'"'"'s brain state is unknown.
