When a person is affected by brain injury, it’s common to feel alone. After all, there’s a good chance that you or your loved one is the only person you know who has been impacted by brain injury.

In fact, brain injury affects 1.4 million people per year in the United States alone, according to the National Center for Injury Prevention and Control. Of this 1.4 million, 1.1 are treated and released from the emergency room, 235,000 are hospitalized, and 50,000 die.

Those at the highest risk for traumatic brain injury are between 0 and 4 years old and 15 and 19 years old, while those with the highest incidents of hospitalization and death are older than 75. In addition, males are twice as likely to suffer from TBI as females.

California, Texas, New York, and Florida have the most annual cases of brain injury, while Vermont, Wyoming, and North Dakota have the fewest.
