A traumatic brain injury ( TBI ), also known as an intracranial injury, is an injury to the brain caused by an external force. TBI can be classified based on severity ranging from mild traumatic brain injury (mTBI/concussion) to severe traumatic brain injury. [ 5] TBI can also be characterized based on mechanism ( closed or penetrating head ...
Stereopsis recovery, also recovery from stereoblindness, is the phenomenon of a stereoblind person gaining partial or full ability of stereo vision ( stereopsis ). Recovering stereo vision as far as possible has long been established as an approach to the therapeutic treatment of stereoblind patients. Treatment aims to recover stereo vision in ...
Concussion. Acceleration (g-forces) can exert rotational forces in the brain, especially the midbrain and diencephalon. A concussion, also known as a mild traumatic brain injury ( mTBI ), is a head injury that temporarily affects brain functioning. [ 9] Symptoms may include loss of consciousness; memory loss; headaches; difficulty with thinking ...
Closed head injury (coup contrecoup) can damage more than the impact sites on the brain, as axon bundles may be torn or twisted, blood vessels may rupture, and elevated intracranial pressure can distort the walls of the ventricles. [7] [10] [11] Diffuse axonal injury is a key pathology in concussive brain injury. [5] The visual system may be ...

[ 1] The patient spends only a few hours in the hospital with minimal preoperative preparation. After surgery, the patient should expect soreness and redness but is generally free to return ...
In traumatic brain injury (TBI), primary brain injury occurs during the initial insult, and results from displacement of the physical structures of the brain. [ 1] Secondary brain injury occurs gradually and may involve an array of cellular processes. [ 1][ 2] Secondary injury, which is not caused by mechanical damage, can result from the ...
