“About 75% of the 2 million brain injuries yearly accounts for a closed brain injury. This means that nothing directly touches the brain. Not all brain injuries are the same; they differ from their severity. Others may appear minor but later on, significant symptoms can appear.

A closed brain injury can come from a sharp blow in the head that shakes and traumatize the brain. A common example is a concussion. Since it is closed, the extent of the injury cannot be identified immediately by the naked eye.

This type of head injury can be caused by falls, sports, vehicular accidents, and acts of violence. About 35.2% of closed head injury is caused by fall. Falls are common to toddlers and kids and elderly.

Open head injuries are considered serious and traumatic. They require medical help immediately. Due to the open wound, patients can suffer from infection and contamination.”
