    摘要: A method and system for the quantitative description of human abnormal brain states, for example, to distinguish cerebral death from a barbiturate induced deep coma, includes an electroencephalograph (EEG) system utilizing scalp electrodes 10 and amplifiers 11, 12. A computer based system controls a multimodal stimulator 17 (clicks, flashes, etc) to provide evoked response data for different sensory systems. The ongoing EEG and averaged response data are processed quantitatively and compared with previously stored normative data, describing brain states in patients free of head trauma, to calculate a set of Z-transformations. The Z-transormations define Z, the brain state vector (BSV), which may be visually displayed, for example, on a cathode ray tube 48. The length, direction and change of BSV overtime provide an evaluation of the anatomical location of any damage, the severity of functional impairment and the rate of improvement or deterioration of the patients's state in order to aid in selection and guidance of treatment.

    摘要: The present invention relates to the field of detecting/preventing migraine attacks. In particular, a system and method for detecting and preventing a migraine episode in a user are provided. The system comprises a brain activity sensor for detecting a brain activity signal; a migraine trigger detection unit for detecting potential migraine triggers, said potential migraine triggers being circumstances that may potentially cause a migraine attack in the user. A processing unit is configured to: process the brain activity signal to identify one or more signal characteristics in the brain activity signal that are indicative of an upcoming migraine attack in the user; identify one or more correlations between the one or more identified signal characteristics in the brain activity signal and the detected potential migraine triggers; determine, based on the identified one or more correlations, one or more personal migraine triggers that are likely to cause a migraine attack in the user; an output unit for providing the user with a personalized feedback which informs the user about the determined one or more personal migraine triggers and/or how the user may prevent the determined one or more personal migraine triggers.
