The National Institutes of Health Stroke Scale, or NIH Stroke Scale (NIHSS), is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke and aid planning post-acute care disposition, though was intended to assess differences in interventions in clinical trials. The NIHSS was designed for the National ...
Language functions such as grammar, vocabulary and literal meaning are typically lateralized to the left hemisphere, especially in right-handed individuals. [7] While language production is left-lateralized in up to 90% of right-handers, it is more bilateral, or even right-lateralized, in approximately 50% of left-handers. [8]
The laterality of the sensory inputs makes a difference insofar as left-sided inputs directed to the intact left hemisphere are not affected by extinction, or affected to a much smaller degree than left-sided inputs directed to the damaged right hemisphere. In other words, the lateral organization of sensory inputs is an important factor in the ...
It has been proposed that negative, withdrawal-associated emotions are processed predominantly by the right hemisphere, whereas the left hemisphere is largely responsible for processing positive, approach-related emotions. This has been called the "laterality-valence hypothesis". [9] One sub-set of laterality in animals is limb dominance.
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
[7] [9] It has been linked to parietal lesions in the left and right hemisphere, stroke and Alzheimer's disease. Initially, researchers tried to isolate the cause to left hemisphere lesions in the parietal lobe because of its similarities to Gerstmann syndrome; however, lesions in the dorsal stream also result in visual agnosia and a piecemeal ...
The left hemisphere is associated with language and calculations, while the right hemisphere is more closely associated with visual-spatial recognition and facial recognition. This lateralization of brain function results in some specialized regions being only present in a certain hemisphere or being dominant in one hemisphere versus the other ...
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]
