Cavitation is a harmful condition arising from head trauma

| Jul 30, 2020 | Uncategorized |

Perhaps someone you know suffered head trauma in a California car accident, a contact sports incident, or a slip and fall accident. Even though that person may feel that the same, you may have started to notice mood swings and other psychological, or even physical, changes. This would signify a traumatic brain injury.

Numerous studies have looked into the damage that TBIs cause. A recent one goes deeper and looks at the tiny bubbles, called microbubbles, that expand and collapse in the cerebral spinal fluid of the brain in the wake of a TBI. The results may be worth noting.

Microbubbles damage brain cells

The results of this study can be found in the July 2020 issue of the journal Global Challenges. It was conducted by Iowa State University researchers and supported by grants from the Office of Naval Research.

Researchers have built on previous studies, which say that the creation and collapse of microbubbles, called cavitation, results in shock waves with a force between 0.1 and 20 megapascals, or 14.5 and 2,900 pounds per square inch. These shock waves can damage the brain cells, in particular the astrocytes, which support and repair the central nervous system.

How researchers tested for changes

To simulate the effects of cavitation, researchers took a 3-D cell culture platform for astrocytic cells, submerged it in a small tank and created microbubbles, some of which adhered to the platform. An ultrasonic device then triggered cavitation. Compared to cells not subject to cavitation, the cells on the platform experienced only half the normal growth. Damaged cells also produced proteins linked to conditions like Parkinson’s and Alzheimer’s disease.

A lawyer to represent you

To suffer a traumatic brain injury after a truck accident or pedestrian accident is not uncommon, but this does not make things any less stressful for you and your family. Fortunately, you may be entitled to compensatory damages. A lawyer may evaluate your case in light of this state’s negligence laws, determine a reasonable amount for a settlement and then negotiate for it on your behalf.
