Traumatic brain injury (TBI) is a critical public health and socio-economic problem throughout the world.
Many cases of head injury, mainly associated to mild TBI, are not recognized by health professionals or are not reported by the patients themselves, so it is called “silent epidemic” because the data reported by epidemiological studies are largely incomplete
There are many kinds of impairments that may occur as a result of TBI. These injuries may impair:
- cognition — concentration, memory, judgment, and mood
- movement abilities — strength, coordination, and balance
- sensation — tactile sensation and special senses such as vision
- TBI sometimes results in seizure disorders (epilepsy). About 1 percent of persons with severe TBI survive in a state of persisting unconsciousness. There is no way to describe fully the human costs of traumatic brain injury: the burdens borne by those who are injured and their families.
