Right hemisphere brain damage (RHD) is the result of injury to the right cerebral hemisphere. [1] The right hemisphere of the brain coordinates tasks for functional communication, which include problem solving, memory, and reasoning. [1] Deficits caused by right hemisphere brain damage vary depending on the location of the damage. [2]
Unequal pupil size is potentially a sign of a serious brain injury. [39] Symptoms are dependent on the type of TBI (diffuse or focal) and the part of the brain that is affected. [40] Unconsciousness tends to last longer for people with injuries on the left side of the brain than for those with injuries on the right. [15]
In visual allochiria, objects situated on one side of the visual field are perceived in the contralateral visual field. [15] In one of the two cases ever recorded, the visual impression received by the right open eye was regularly referred to the left eye, and the patient maintained that she perceived the impression with the left eye that in fact was shut.
In head injury, a coup injury occurs under the site of impact with an object, and a contrecoup injury occurs on the side opposite the area that was hit. [1] Coup and contrecoup injuries are associated with cerebral contusions , [ 2 ] a type of traumatic brain injury in which the brain is bruised .
For example, a stroke affecting the right parietal lobe of the brain can lead to neglect for the left side of the visual field, causing a patient with neglect to behave as if the left side of sensory space is nonexistent (although they can still turn left). In an extreme case, a patient with neglect might fail to eat the food on the left half ...
“The brain changes, and it doesn’t recover when you just stop the drug because the brain has been actually changed,” Kreek explained. “The brain may get OK with time in some persons. But it’s hard to find a person who has completely normal brain function after a long cycle of opiate addiction, not without specific medication treatment.”
A concussion, also known as a mild traumatic brain injury (mTBI), is a head injury that temporarily affects brain functioning. [8] Symptoms may include headache, dizziness, difficulty with thinking and concentration, sleep disturbances, mood changes, a brief period of memory loss, brief loss of consciousness; problems with balance; nausea; blurred vision; and mood changes.
Brain injuries are very hard to predict in the outcome. Many tests and specialists are needed to determine the likelihood of the prognosis. People with minor brain damage can have debilitating side effects; not just severe brain damage has debilitating effects. The side-effects of a brain injury depend on location and the body's response to injury.
