Brain injuries can vary in severity, but even mild injuries can have long-lasting effects. They usually happen when the brain is damaged by an external force, like a blow to the head, or by an internal factor, like oxygen deprivation. These injuries typically fall into two categories, including:
Traumatic Brain Injury (TBI)
A TBI is most often caused by a sudden impact to the head or a jolt that disrupts the brain’s normal function. These injuries are often caused by accidents like car crashes, falls, or physical assaults. Traumatic brain injuries are medically classified as mild, moderate, or severe, depending on how extensive the damage is.
Even a mild TBI (referred to as a concussion) can lead to headaches, memory issues, and difficulties concentrating. More severe TBIs may cause long-term disabilities, loss of mental function, and emotional instability issues.
Acquired Brain Injury (ABI)
ABIs happen due to internal factors, like a lack of oxygen to the brain, exposure to toxins, or a medical incident like a stroke. Even though they’re not caused by external trauma, ABIs can be just as damaging as TBIs.
The effects of ABIs can range from mild cognitive impairments to profound physical disabilities.
