Depends on a lot. This is often the debate which engages forensic neuropsychologists (see http://forensicneuropsychology. Com) and forensic neurologists. Results can vary greatly even with similar ct or MRI findings. Generally severity, presence of intracranial bleeding, elevated icp, early or especially post-traumatic seizures, locaiton of injury, shearing, and pre-injury factors ie. Age, prior injury, health etc.
No. A person can have full recovery. The best time to tell what will be permanent is those symptoms still present after one year. A few predictors of permanent damage is how much memory is lost and the length of being unconcious or if there was lack of oxygen for a prolonged time.
No. It depends on the cause, location, amount of injured brain. Concussion is a mild brain injury. Most people recover from mild injury frin trauma, even from stroke.
OCD is an uncommon, . but well-documented, consequence of TBI. The pattern of OCD, I.e., the types of obsessions & compulsions, are very similar amongst patients with TBI, whether they have mild TBI & normal MRI's or moderate & severe TBI with bruising of the the fronto-temporal cortex, subcortical structures (caudate nucleus) or both on their MRI's. Just one more thing for which you need therapy &, maybe, medication.
Brain damage. Tbi- traumatic brain injury is when the brain is injured from a strike, fall, accident, explosion or any other concussive injury to the head injuring the underlying soft brain tissue. They can be mild from concussion to severe such as persistent vegetative state.
Varying definitions. As others note this reflects an injury to the brain which can be very mild and usually with transitory effects to very severe with permanent and life-changing effects. See http://cpancf. Com/headinjuryclassification. Asp.
Damage from trauma. A traumatic brain injury is brain damage due to trauma to the head and brain, as opposed to infection, spontaneous hemorrhage from an aneurysm, damage due to inadequate breathing, low blood sugar or other metabolic abnormalities.
Several. Acutely you have headache, pain at the trauma site, possibly memory loss, over time there can be has, mood symptoms, memory symptoms, behavioral issues.
Area of damage. The symptoms of brain injury will depend on the area that is injured. You should speak to a neurologist to give more information.
