Brainwaves could be the next health vital sign (ScienceDaily):
“Simon Fraser University researchers hope that a brain vital-sign test becomes as routine during a doctor’s check-up as taking a blood pressure or heart rate measurement…In a recent article published in the journal Frontiers in Neuroscience, the team introduces the world’s first advancement in physiology-based brain vital signs. Their discovery makes it possible to translate complex brainwaves into objective, practical and deployable brain vital signs, using longstanding brainwave technologies that have existed for nearly a century.
HealthTech Connex Inc. is currently developing the NeuroCatchTM platform to enable the highest quality recordings of the brain’s vital signs…
“The brain vital-sign framework described in Frontiers in Neuroscience represents the first step towards an easy way to monitor brain health,” says D’Arcy. “Potential applications are in concussion, brain injury, stroke, dementia and other devastating brain diseases and disorders.”
Study: Developing Brain Vital Signs: Initial Framework for Monitoring Brain Function Changes Over Time (Frontiers in Neuroscience)
- From the abstract: Clinical assessment of brain function relies heavily on indirect behavior-based tests. Unfortunately, behavior-based assessments are subjective and therefore susceptible to several confounding factors. Event-related brain potentials (ERPs), derived from electroencephalography (EEG), are often used to provide objective, physiological measures of brain function…Clinical evaluations of healthy brain functioning is moving from indirect subjective behavior-based tests, to objective, physiological measures of brain function, such as those derived from ERPs. We have previously demonstrated the essential role for clinical ERPs to evaluate functional status following serious injury and/or disease. The current study addressed an important gap: the need for a clinical-accessible brain vital sign framework that utilizes well-established ERPs. As an initial step, the framework was used to evaluate healthy brain function across the life span. The findings confirmed the ERPs at the individual level, verified predictable age-related differences, and demonstrated successful linear transformation to create the brain vital sign framework.
