  2. Lateralization of brain function - Wikipedia

    en.wikipedia.org/wiki/Lateralization_of_brain...

    The lateralization of brain function (or hemispheric dominance[1][2] / lateralization [3][4]) is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The median longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum.

  3. Cerebral infarction - Wikipedia

    en.wikipedia.org/wiki/Cerebral_infarction

    Cerebral infarction. Cerebral infarct. Specialty. Neurology. 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]

  4. Hemispatial neglect - Wikipedia

    en.wikipedia.org/wiki/Hemispatial_neglect

    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. It is defined by the inability of a person to process and perceive stimuli towards the ...

  5. Lacunar stroke - Wikipedia

    en.wikipedia.org/wiki/Lacunar_stroke

    Lacunar stroke or lacunar cerebral infarct (LACI) is the most common type of ischemic stroke, resulting from the occlusion of small penetrating arteries that provide blood to the brain's deep structures. Patients who present with symptoms of a lacunar stroke, but who have not yet had diagnostic imaging performed, may be described as having ...

  6. Right hemisphere brain damage - Wikipedia

    en.wikipedia.org/wiki/Right_hemisphere_brain_damage

    Psychiatry, Neurology. 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 ...

  7. Gerstmann syndrome - Wikipedia

    en.wikipedia.org/wiki/Gerstmann_syndrome

    Gerstmann syndrome is typically associated with damage to the inferior parietal lobule of the dominant hemisphere. It is classically considered a left-hemisphere disorder, although right-hemisphere damage has also been associated with components of the syndrome. [2] It is named after Jewish Austrian-born American neurologist Josef Gerstmann. [3]

  8. Stroke - Wikipedia

    en.wikipedia.org/wiki/Stroke

    Emotional lability occurs in about 20% of those who have had stroke. Those with a right hemisphere stroke are more likely to have empathy problems which can make communication harder. [235] Cognitive deficits resulting from stroke include perceptual disorders, aphasia, [236] dementia, [237] [238] and problems with attention [239] and memory. [240]

  9. National Institutes of Health Stroke Scale - Wikipedia

    en.wikipedia.org/wiki/National_Institutes_of...

    Approximately 98% of humans have verbal processing take place in the left hemisphere, indicating that the NIHSS places more value on deficits in the left hemisphere. This results in lesions receiving a higher (worse) score when occurring in the left hemisphere, compared to lesions of equal size in the right hemisphere.
