The invention relates to a method and system for analyzing the status of a subject. A cordless recording device (10) comprising a set of electrodes (1, 2) is attached on the forehead of the subject (100) to collect brain wave signal data from the subject. Based on the brain wave signal data, status information indicative of the status of the subject during a measurement period is generated. A bio impedance signal (31) is further measured through two electrodes (1, 2) of the electrode set and heart rate data is derived from the bio impedance signal. The heart rate data is utilized to enhance the quality of the status information, which is typically sleep state information. The invention also relates to a recording device attachable to the forehead of the subject. The recording device may comprise a data memory (240) for storing the data measured from the subject during the measurement period. |
