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]
By testing the limits of patients' performance, it is then able to make correlations between a normal and damaged brain. There is some discussion on the standardized interruption of the test. [2] The children's version of the test is for 8–12 years old. This test has 149 different items that also measure on a continuum from 0 to 2.
The Halstead–Reitan Neuropsychological Test Battery (HRNB) and allied procedures is a comprehensive suite of neuropsychological tests used to assess the condition and functioning of the brain, including etiology, type (diffuse vs. specific), localization and lateralization of brain injury.
Hemispatial neglect is a neuropsychological condition in which, after damage to one hemisphere of the brain (e.g. after a stroke), a deficit in attention and awareness towards the side of space opposite brain damage (contralesional space) is observed.
Lateral brain damage can also affect visual perceptual spatial resolution. People with left hemisphere damage may have impaired perception of high resolution, or detailed, aspects of an image. People with right hemisphere damage may have impaired perception of low resolution, or big picture, aspects of an image.
First proposed by Swiss psychologist André Rey in 1941 and further standardized by Paul-Alexandre Osterrieth in 1944, it is frequently used to further explain any secondary effect of brain injury in neurological patients, to test for the presence of dementia, or to study the degree of cognitive development in children.
Their drawings contain fewer angles, spatial alterations, a lack of perspective and simplifications, which are uncharacteristic of left hemisphere or right hemisphere patients. Constructional disabilities are present early on in the disease and get progressively worse over time; [ 4 ] however even patients with advanced Alzheimer's disease may ...
The drug is injected into one hemisphere at a time through the right or left internal carotid artery. If the right carotid is injected, the right side of the brain is inhibited and cannot communicate with the left side. The effect shuts down any language and/or memory function in that hemisphere in order to
