- Trauma, such as head injuries, can inflict direct physical damage to the blood-brain barrier, compromising its structural integrity.
- Trauma triggers an inflammatory response, releasing cytokines and other immune system components that can disrupt the tight junctions of the blood-brain barrier.
- The inflammatory cascade induced by trauma can increase blood-brain barrier permeability, allowing molecules that would typically be restricted to enter the brain.
- Traumatic events elevate the risk of neuroinflammation, further amplifying the challenges the blood-brain barrier faces in maintaining its protective function.
- Trauma's impact may not be immediately evident, and its lingering effects can contribute to long-term alterations in blood-brain barrier function.
7. Disrupted circadian rhythm
- Disrupting the circadian rhythm, our internal body clock, interferes with the regular sleep-wake cycle, impacting the body's natural processes, including blood-brain barrier function.
- A disrupted circadian rhythm can lead to compromised tight junctions in the blood-brain barrier. These tight junctions act like gatekeepers, controlling what enters and exits the brain, and disruptions can lead to increased permeability.
- Sleep disturbances, common with circadian rhythm disruption, trigger inflammatory responses. Chronic inflammation contributes to blood-brain barrier dysfunction, making it more susceptible to leaks.
- Disruptions in the circadian rhythm affect melatonin production. Melatonin, known as the sleep hormone, is crucial in supporting the blood-brain barrier's integrity. Reduced melatonin levels may contribute to increased permeability.
- Individuals working irregular shifts experience circadian rhythm disruption. Studies indicate that shift workers may face an elevated risk of blood-brain barrier dysfunction due to prolonged disruptions in their natural sleep-wake patterns.
