Device for determining insomnia

Abstract

The device (1) is used to determine whether a patient (8) has insomnia. It has a sensor unit (2) for recording at least one EEG measurement signal of the patient's (8) brainwave and a control and evaluation unit (3) for evaluating the recorded EEG measurement signal. The control and evaluation unit (3) is designed to perform an objective recording routine, instructing the patient (8) to open their eyes for a specified period and to close them for a specified period before recording the EEG measurement signal. The device then initiates the recording of the EEG measurement signal for at least one eye-opening period and for at least one eye-closing period.The control and evaluation unit (3) is further designed to perform an evaluation of the EEG measurement signal thus recorded, and to extract from the EEG measurement signal at least one first partial measurement signal which lies within the at least one eye-opening time interval and at least one second partial measurement signal which lies within the at least one eye-closing time interval, and to decide on the presence of insomnia if the at least one second partial measurement signal which lies within the at least one eye-closing time interval has a lower proportion of α-waves than in a healthy person.
