The visual difficulties in Bálint's syndrome are usually due to damage to the parieto-occipital lobes on both sides of the brain. The parietal lobe is the middle area of the top part of the brain and the occipital lobe is the back part of the brain. (It usually does not affect the temporal lobes) [citation needed]
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.
Animation. Parietal lobe (red) of left cerebral hemisphere. The parietal lobe is defined by three anatomical boundaries: The central sulcus separates the parietal lobe from the frontal lobe; the parieto-occipital sulcus separates the parietal and occipital lobes; the lateral sulcus (sylvian fissure) is the most lateral boundary, separating it from the temporal lobe; and the longitudinal ...
Gerstmann syndrome is a neurological disorder that is characterized by a constellation of symptoms [1] that suggests the presence of a lesion usually near the junction of the temporal and parietal lobes at or near the angular gyrus. Gerstmann syndrome is typically associated with damage to the inferior parietal lobule of the dominant hemisphere ...
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.
The parietal lobe is also critical for remapping spatial position across saccades. [5] There is an attentional subsystem responsible for moving the eyes, head, and body to focus on different images. Damage at various levels of this system could lead to trouble localizing a stimulus or hemispatial neglect which manifests as perseverative errors ...
It affects the subcortical white matter, particularly that of the parietal and occipital lobes. PML destroys oligodendrocytes and produces intranuclear inclusions. It is similar to another demyelinating disease, MS, but progresses much more quickly. The breakdown of myelin is proportional to the degree of immunocompromise. [11]
The frontal and parietal lobes were found to be critical for executive control processes, which was demonstrated by significantly worse performance on specific executive functioning subtests in participants with damage to frontal and parietal regions, as well as the white matter tracts connecting these regions, such as the superior fronto ...
