Non-traumatic brain injuries can arise from several non-impact related factors, and exposure to toxins is a significant cause of such injuries. When the body is exposed to certain chemicals (such as heavy metals like lead or organic solvents), it can lead to brain damage or dysfunction through chemical processes rather than physical injury. This exposure can disrupt the normal functioning of neurons, leading to long-term cognitive or neurological deficits.

Car accidents, falls, and gunshot wounds, on the other hand, are typically categorized as traumatic brain injuries because they involve direct trauma to the head, which can cause physical damage to brain structures. These scenarios highlight the distinction between injuries resulting from direct mechanical forces and those arising from chemical or biological factors, reinforcing why exposure to toxins is correctly identified as a cause of non-traumatic brain injury.
