The present invention relates to a brain dysfunction and seizure detector monitor and system, and a method of detecting brain dysfunction and/or seizure of a subject. The various embodiments of the system of the present invention were developed for the brain activity and preferably EEG monitoring of a single patient or multiple patients. Preferably, the system or monitor of the present invention also includes one or more seizure detection algorithms. The analysis method is specifically optimized to amplify abnormal brain activity and minimize normal background activity. This analysis yields a seizure index whose value is directly related to the current presence of ictal activity in the signal. In addition, a seizure probability index based on historical values of the aforementioned seizure index, is derived for diagnostic purposes. The seizure probability index quantifies the probability that the patient has exhibited abnormal brain activity since the beginning of the recording. The real-time seizure index, and the historical seizure probability index, can be used in the context of an emergency and/or clinical situation to assess the status and well being of a patient's brain, or can be used to automatically administer treatment to stop the seizure before clinical signs appear.

An EEG monitoring apparatus (2) adapted to be carried continuously by a person being monitored comprises means adapted for measuring at least one EEG signal from the person carrying the apparatus and a signal processing means for analysing said at least one EEG signal and adapted to identify or predict predetermined biological incidents in said person based on said analysis. The EEG monitoring apparatus (2) further comprises a decision means adapted to decide when information is to be presented to said person and a message selection means for selecting a voice message providing said person with information, as well as an acoustic transducer adapted for presenting the selected voice message to the person. The invention also provides a method for presenting voice messages.

A measurement device is presented for use in an EEG measurement performed in the presence of a magnetic field. The device comprises a wiring array for connecting an electrodes arrangement to an electroencephalogram (EEG) monitoring device. The wiring array comprises a plurality of sampling lines arranged to form a first group of sampling lines arranged in a spaced-apart substantially parallel relationship extending along a first axis, at least some of said sampling lines being wire bundles of said first group comprising a plurality of first wires for connecting to a corresponding first plurality of electrodes of said EEG electrodes arrangement; and a second group of sampling lines arranged in a spaced-apart substantially parallel relationship extending along a second axis, intersecting with said first axis, such that said second group of bundles crosses said first group of bundles to form a net structure, at least some of said sampling lines being wire bundles of said second group comprising a plurality of second wires for connecting to a corresponding second plurality of electrodes of said EEG electrodes' arrangement. The wiring array is configured and operable for transmitting a signal measured by the respective electrodes to the EEG monitoring device, enabling generation of EEG data indicative of the neural signal profile along tow directions and characterized by reduced motion artifact and/or reduced gradient artifact associated with the presence of the magnetic field during the EEG measurement.

A dual purpose sleep wearable headgear for both monitoring and stimulating the brain of a sleeping person is disclosed that provides a simple to use and safe platform for wearing consumer-type dual use brain stimulation and monitoring devices during sleep. The headgear enables a user to sleep comfortably while wearing the electronics and related electrodes needed for both EEG monitoring and transcranial electrical stimulation. The headgear can accept and support a miniaturized dual use monitoring/stimulation device on the forehead or the top of the head, where the bulk of the monitoring/stimulation device will not interfere with the user's sleeping position. The headgear disclosed takes the guesswork out of electrode placement, because the electrodes are prepositioned or are easily adjustable according to a predetermined pattern of electrode placement, and are appropriately sized so as to allow comfortable transcranial stimulation without producing skin irritation, and without awakening the user.

A new neuro-behavioral test with analysis algorithms has been developed for use in screening individuals for attention deficit hyperactivity disorder (ADHD) and for the quantitative evaluation of ADHD medication/therapy in diagnosed patients. This technique combines a 15 minute auditory-based test of attention with simultaneous EEG monitoring by a wireless, portable data acquisition device. This system acquires both behavioral response (i.e., reaction times to target stimuli, as well as errors of omission/commission) and EEG waveforms. All of the data is simultaneously processed by the algorithms to produce several representative indices. These indices are then combined to produce an overall neuro-behavioral index that represents the degree by which both “behavioral” and “EEG” attention is maintained throughout the test.

Embodiments of the present invention (herein referred to simply as “the invention”) comprise an EEG monitoring device worn on or around a user's ears. In some embodiments of the invention, the device comprises a flexible printed circuit containing EEG sensors, skin adhesives or adhesive sensors, and a flexible extension to position the sensor adjusting the user's head size. The device may be designed so that when worn by a user, the sensors are placed at specific points on a user's head in order to accurately capture electroencephalography signals. Said specific points may be one or more points of a 10-10 EEG system. The EEG sensors may comprise or may be made of an adhesive material.
