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]
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 ...
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 .
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] Symptoms are also dependent on the injury's severity. With mild TBI, the patient may remain conscious or may lose consciousness for a few seconds or minutes. [41]
Although workplace injuries remain below pre-pandemic levels, there has been a massive increase in work-related illness, data shows. Workplace injuries, illnesses increase, new data shows Skip to ...
For example, when something is placed on the left hand of a blindfolded patient with the two hemispheres disconnected, the left hand can pick the correct object within a set of objects but the right hand cannot. [6] Audition – Though most of the input from one ear would go through the same ear, the opposite ear also receives some input ...
Injury to the right side of the brain will affect the left visual fields of each eye. The more posterior the cerebral lesion, the more symmetric (congruous) the homonymous hemianopsia will be. For example, a person who has a lesion of the right optic tract will no longer see objects on his left side.
Diffuse axonal injury after a motorcycle accident. MRI after 3 days: on T1-weighted images the injury is barely visible. On the FLAIR, DWI and T2*-weighted images a small bleed is identifiable. DAI is difficult to detect since it does not show up well on CT scans or with other macroscopic imaging techniques, though it shows up microscopically. [9]
