In neurology, conduction aphasia, also called associative aphasia, is an uncommon form of difficulty in speaking (aphasia). It is caused by damage to the parietal lobe of the brain. An acquired language disorder, it is characterised by intact auditory comprehension, coherent (yet paraphasic) speech production, but poor speech repetition.
The parietal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The parietal lobe is positioned above the temporal lobe and behind the frontal lobe and central sulcus. The parietal lobe integrates sensory information among various modalities, including spatial sense and navigation (proprioception), the main ...
The posterior parietal cortex (the portion of parietal neocortex posterior to the primary somatosensory cortex) plays an important role in planned movements, spatial reasoning, and attention. Damage to the posterior parietal cortex can produce a variety of sensorimotor deficits, including deficits in the perception and memory of spatial ...
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]
Psychiatry, Neurology. 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 ...
Gerstmann syndrome. Gerstmann syndrome is a neuropsychological 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 ...
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 ...
Anomic aphasia occurring by itself may be caused by damage to almost anywhere in the left hemisphere and in some cases can be seen in instances of right hemisphere damage. [7] Anomia can be genetic or caused by damage to various parts of the parietal lobe or the temporal lobe of the brain due to traumatic injury, stroke, or a brain tumor. [8]
