What is a common cause of acquired brain injury?

A common cause of acquired brain injury is any blow to the head, which encompasses a range of incidents from falls to sports injuries and vehicle accidents. This type of injury falls under the category of traumatic brain injuries (TBIs), which can lead to significant physical, cognitive, and emotional changes. The brain is particularly vulnerable to damage from external forces, and the severity can vary from mild concussions to more severe injuries that result in long-term disabilities.

In contrast, chronic stress, genetic disorders, and respiratory illnesses do not directly cause acquired brain injuries. Chronic stress is more likely to lead to mental health issues or other health problems rather than direct injury to brain tissue. Genetic disorders typically arise from inherited conditions rather than being acquired due to external factors. Respiratory illnesses affect the body’s oxygen supply but do not involve a direct impact on the brain that would result in acquired injury. Therefore, the option that describes a direct, physical insult to the brain is clearly identified as a common cause of acquired brain injury.
