What happenes when soft soft tissue of the brain collides against the skull?

When soft tissue of the brain collides against the skull, it can result in a traumatic brain injury (TBI). This impact can cause bruising, bleeding, and swelling of the brain, leading to potential damage to neural pathways and loss of function. Symptoms may include headaches, confusion, and cognitive impairment, depending on the severity of the injury. In severe cases, such collisions can result in long-term neurological issues or even death.
