Athletes absorb several hundred mild traumatic brain injuries (mTBI)/concussions every year; however, the consequence of these on the brain is poorly understood. Therefore, an animal model of single and repetitive mTBI that consistently replicates clinically relevant symptoms provides the means to advance the study of mTBI and concussion.

This protocol describes repetitive hypoxic preconditioning, or brief exposures to systemic hypoxia that reduce infarct volumes and blood-brain barrier disruption following transient middle cerebral artery occlusion in mice. It also details dual quantification of infarct volume and blood-brain barrier disruption after stroke to assess the efficacy of neurovascular protection.
FAQs
Damage to vessel integrity and signaling can weaken the coordinated function of endothelial cells, pericytes, astrocytes, neurons, and extracellular matrix. As this neurovascular unit loses regulatory control, the blood-brain barrier may become abnormally permeable. Barrier leakage can then contribute to edema and expose neural tissue to conditions that worsen secondary injury.
Reduced perfusion limits the delivery of blood to affected neural tissue and can intensify neuronal stress. In neurovascular injury, altered vessel function and disrupted signaling may therefore produce consequences beyond the initial damage. Evaluating perfusion helps researchers connect vascular impairment with tissue responses and assess whether an intervention preserves circulation during recovery.
Inflammation can disturb communication among vascular and neural cells, adding to the original vessel or tissue insult. This disruption may promote barrier leakage, edema, and further impairment of blood flow, creating conditions for secondary neuronal damage. Studying these linked responses helps explain why injury progression depends on interactions within the neurovascular unit rather than on neurons alone.
Trauma, ischemia, hemorrhage, and inflammation represent distinct initiating conditions for neurovascular injury, but each can disrupt vessel integrity and neurovascular signaling. Their effects may converge on reduced perfusion, barrier leakage, edema, and secondary neuronal damage. Comparing these contexts allows neuroscience studies to examine shared mechanisms while relating vascular responses to specific neurological disorders.
Microscopy can visualize structural changes in vessels and surrounding tissue, while vascular imaging evaluates blood-vessel condition and perfusion-related changes. Molecular analyses examine signaling and tissue responses associated with barrier disruption, inflammation, or injury progression. Used together, these approaches provide complementary evidence for assessing the neurovascular unit rather than relying on a single measurement.
Researchers investigate neurovascular injury to clarify how stroke and traumatic brain injury progress after the initial event. Imaging and microscopy can document vascular and tissue changes, whereas molecular analyses help characterize responses within the neurovascular unit. These findings support evaluation of disease mechanisms and guide efforts to preserve perfusion, limit inflammation, and promote neural recovery.
Studies can assess vessel integrity, blood-brain barrier leakage, perfusion, edema, inflammation, and secondary neuronal damage. They can also evaluate whether a treatment protects the neurovascular unit or supports recovery of neural tissue. Combining structural, vascular, and molecular observations helps researchers interpret tissue responses and determine whether an approach improves conditions linked to functional recovery.
