What are some common causes of acquired brain injuries?

Acquired brain injuries (ABIs) refer to brain damage that occurs after birth and is not hereditary, congenital, or degenerative. Common causes of ABIs include medical events that affect the brain's function. Stroke is a significant cause, occurring when blood flow to the brain is interrupted, leading to cell death. Tumors can exert pressure on brain tissue or disrupt normal blood flow and function, while infections such as meningitis can cause inflammation and damage to brain tissues.

The other options, while they address different aspects of brain health, do not specifically encapsulate the common causes of acquired brain injuries. For instance, concussions and sports injuries are types of traumatic brain injuries rather than a comprehensive list of acquired brain injury causes. Genetic disorders and aging are associated with developmental and degenerative conditions. Environmental toxins can affect neurological health but are less direct causes of acquired brain injuries when considering established categories. Thus, the selection of stroke, tumors, and infections as causes provides a more accurate representation of the common sources of acquired brain injuries.
