Final answer:
Infant subdural hematoma can be caused by birth trauma, shaken baby syndrome, and accidental falls, with each cause linked to severe brain injuries and related complications.
Step-by-step explanation:
An infant subdural hematoma can be caused by birth trauma, shaken baby syndrome, and accidental falls. These are all significant causes of head and traumatic brain injuries, which can result in serious complications such as brain swelling, retinal hemorrhage, and long-term disability or death. Shaken baby syndrome, a severe form of child abuse, is characterized by a group of medical symptoms including brain swelling and retinal hemorrhage resulting from forcibly shaking or impacting an infant's head. Another predominant cause of such injuries is accidental falls particularly among young children, while birth trauma can occur during the labor and delivery process.
