Brain-computer interface test battery for the physiological assessment of nervous system health

摘要

A battery of three or more sensory and cognitive challenge tasks actively or dynamically challenge the brain to monitor its state for assessment of injury, disease, or compound effect, among others. The system analyzes and assesses a personalized biometric brain health signature by integrating the use of electroencephalography (EEG), somato-sensory, neuropsychological, and/or cognitive stimulation, and novel signal processing and display. The system also provides for early detection of dementia, including Alzheimer's disease (AD), vascular dementia (VAD), mixed dementia (AD and VAD), MCI, and other dementia-type disorders, as well as brain injury states such as mild Traumatic Brain Injury and can provide some or all of the following improvements over conventional systems and methods, including: (1) Increased sensitivity, specificity, and overall accuracy; (2) early detection of disease and injury; and (3) enhanced portability with remote data acquisition capability.
