The long-term effects of moderate to severe TBI can include challenges with attention span and the ability to concentrate and remember. These are known as cognitive problems. Difficulties with processing input from the senses, such as touch, vision, hearing, taste and smell may also occur. Other effects can include, seizures, chronic pain, sleep disorders, loss of bladder or bowel control, and a variety of social and emotional challenges.
A severe traumatic brain injury involves an unconscious state or coma that lasts days, weeks, months, or even years. Typically, the greater the amount of brain damage, the longer a person remains in a coma, and the more challenging the recovery may be.
It’s important to keep in mind that every traumatic brain injury is different, and every person responds differently.
