Abstract: The present invention relates to systems and methods for assessing brain health and detecting neurological conditions. The invention more particularly relates to systems and methods for diagnosing neurological conditions and analyzing rain health from analysis of a biological fluid sample, such as a saliva sample, that looks for and determines the significance of peripheral markers of blood-brain barrier disruption. The present invention further provides a diagnostic system and method with a higher negative predictive value of brain injury than currently known tests are able to provide, so as to reduce the need for computerized tomography or magnetic resonance imaging scans to affirmatively determine that brain or cerebrovascular injury has not occurred, and thus to improve suspected brain injury patient health care while reducing the expense of such care.
