"Head injury" is a broad term that describes a vast array of injuries that occur to the scalp, skull, brain and underlying tissue and blood vessels in the head.
Head injuries are commonly referred to as brain injury, or traumatic brain injury (TBI), depending on the extent of the head trauma.
The person may have varying degrees of symptoms associated with the severity of the head injury. The following are the most common symptoms of a head injury. However, each individual may experience symptoms differently. The symptoms of a head injury may resemble other problems or medical conditions. Always consult your physician.
Symptoms of Mild Head Injury (Including Concussion)
- Raised, swollen area from a bump or a bruise
- Small, superficial (shallow) cut in the scalp
- Headache
- Sensitivity to noise and light
- Irritability
- Confusion

- Change in sleep patterns
- Blurred vision
- "Tired" eyes
- Ringing in the ears (tinnitus)

Concussions are a form of mild traumatic brain injury (TBI). TBI is likely underreported, since many patients do not seek medical care or do so at facilities that do not record this information. Inova has concussion programs at Inova Fairfax Hospital, Inova Loudoun Hospital and Inova Mount Vernon Hospital.
