• Approximately 2  million Traumatic Brain Injuries (TBIs) occur in the United States every year.
• 230,000 TBIs are severe enough to require hospital admission and 99,000 cause an enduring disability. 
• Annually, approximately 50,000 people die of traumatic brain injury.
• In the US, approximately 34% of all deaths caused by injury are from TBI.
• About 1,000,000 Americans receive emergency care for a TBI.
• Millions of people in the US live with a disability caused by TBI.
• Males are twice as likely as females to sustain TBI, and they have a higher chance of sustaining more severe injuries than females.
• People between the ages of 15 and 24 are at the highest risk of sustaining a TBI
• Children and those over the age of 65 are at increased risk for TBI.
• Those living in rural areas have higher rates of TBI than those in urban areas.
•  An alarming number of career-ending concussions among top players has caused the National Football League and National Hockey League to rethink their views of concussion

• Motor vehicle accidents are the leading cause of TBI -  44%. 
• Work place accidents are the second leading cause of TBIs
• Falls cause 26% of TBIs, especially among the elderly.
• Sports and recreation activities cause13% 
• Non-firearm assaults account for 9% 
• Firearm assaults cause 8%
• Of those that require hospitalization, almost half result from motor vehicle accidents

• Annual TBI accounts for $56 billion in medical and rehabilitation costs, and lost productivity. 
• For an individual who has survived a severe, traumatic brain injury the lifetime cost can exceed $4 million.
• A severe TBI with acute rehabilitation averages $1,000 per day. This acute rehabilitation averages 55 days.
• Those who do not survive a TBI accumulate the highest medical cost ­ about $454,717 per TBI fatality.
• Mild injuries are the most common. The ratio of 8:1:1 represents mild to moderate, to severe brain injuries.
• Mild to moderate brain injuries can cause devastating impairments that destroy lives just as effectively as more severe injuries. 
• Mild brain injuries typically do not even require hospitalization yet they can cause profound, life-long difficulties.
• Difficulties caused by milder brain injuries typically do not become apparent until the individual attempts to resume their usual daily activities, the environment places increasing demands on them, uncovering additional psychosocial consequences. See examples below.:

• Social consequences of mild, moderate, and severe TBI are many and serious, including:
• Loss of sense of self
• Social isolation
• Increased risk of suicide
• Divorce
• Chronic unemployment
• Economic strain
• Substance abuse
• Recent studies warn of relationships between mild TBI and violence in juveniles. 
• Other studies of death row inmates reveal a high incidence of TBI.
• These consequences are tragic to individuals, and families, and place additional burdens on social service agencies, law enforcement, and the courts. 
• The homeless account for a yet another large number of mild TBI survivors who have slipped through the proverbial cracks
• As individuals with TBI attempt to resume their usual daily activities, the environment places increasing demands on them, uncovering additional psychosocial consequences. For example:
• Executive dysfunction may become obvious only in the workplace.
• Behavioral changes affecting interpersonal relationships may appear after leaving inpatient care.
• Spiraling adverse consequences of TBI may become apparent not only for persons with TBI but also for their significant others.
• Family members report depression, social isolation, and anger.
• Overall family functioning and relationships are disrupted. Such consequences may continue and, in some instances, worsen with age

    Brain injury can change the very nature of family life; the resultant emotional difficulties can affect  the cohesiveness of the family unit. Typically, the emotional damage is intense, affecting family and friends for years afterward and sometimes leading to the breakup of previously stable family units.
