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]
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.
Hemimegalencephaly (HME), or unilateral megalencephaly, is a rare congenital disorder affecting all or a part of a cerebral hemisphere. [2] It causes severe seizures, which are often frequent and hard to control. A minority might have seizure control with medicines, but most will need removal or disconnection of the affected hemisphere as the ...
Anosognosia is a condition in which a person with a disability is cognitively unaware of having it due to an underlying physical condition. Anosognosia results from physiological damage to brain structures, typically to the parietal lobe or a diffuse lesion on the fronto-temporal-parietal area in the right hemisphere, [1] [2] [3] and is thus a neuropsychiatric disorder.
TMoA is generally characterized by reduced speech output, which is a result of dysfunction of the affected region of the brain. [1] The left hemisphere is usually responsible for performing language functions, although left-handed individuals have been shown to perform language functions using either their left or right hemisphere depending on ...
Dejerine interpreted this case as a disconnection of the speech area in the left hemisphere from the right visual cortex. In 1965, Norman Geschwind , an American neurologist, wrote ‘Disconnexion syndromes in animals and man’ where he described a disconnectionist framework that revolutionized neurosciences and clinical neurology.
Amorphosynthesis, also called a hemi-sensory deficit, is a neuropsychological condition in which a patient experiences unilateral inattention to sensory input. [1] This phenomenon is frequently associated with damage to the right cerebral hemisphere resulting in severe sensory deficits that are observed on the contralesional (left) side of the body.
right hemisphere brain damage and developmental right hemisphere syndrome [10] [24] [25] social-emotional processing disorder [26] [27] Gerstmann syndrome [28] [29] There is diagnostic overlap between nonverbal learning disorder and autism, and some clinicians and researchers consider them to be the same condition.
