Heterotopagnosia
Heterotopagnosia is a neuro-psychological syndrome caused by brain damage in the left parietal lobe and corresponding to an acquired inability in pointing at and locating another person's body parts.Degos JD, Bachoud-Levi AC, Ergis AM, Petrissans JL & Cesaro P (1997) Selective inability to point to extrapersonal targets after left posterior parietal lesions: An Objectivization disorder?, Neurocase, 3:1, 31-39, DOI: 10.1080/13554799708404032Degos JD, Bachoud-Levi AC. Pointing and its object: towards the neuropsychology of objectivation. Rev Neurol (Paris). 1998 May;154(4):283-90. Its name comes from the Greek: "hetero" which means the other from a pair, "a" combined with "gnosis" means without knowledge, and "topos" means location. This clinical syndrome is distinct from autotopagnosia, another group of cognitive deficits associated with difficulties in locating body parts on own's one body. Allotopagnosia is another related disorder in which the patient cannot point at any external ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autotopagnosia
Autotopagnosia from the Greek ''a'' and ''gnosis,'' meaning "without knowledge", ''topos'' meaning "place", and ''auto'' meaning "oneself", autotopagnosia virtually translates to the "lack of knowledge about one's own space," and is clinically described as such. Autotopagnosia is a form of agnosia, characterized by an inability to localize and orient different parts of the body. The psychoneurological disorder has also been referred to as "body-image agnosia" or "somatotopagnosia." ''Somatotopagnosia'' has been argued to be a better suited term to describe the condition. While autotopagnosia emphasizes the deficiencies in localizing only one's own body parts and orientation, ''somatotopagnosia'' also considers the inability to orient and recognize the body parts of others or representations of the body (e.g., manikins, diagrams). Typically, the cause of autotopagnosia is a lesion found in the parietal lobe of the left hemisphere of the brain. However, it as also been noted that p ...

Hemorrhagic Stroke
A stroke is a disease, medical condition in which poor cerebral circulation, blood flow to the brain causes cell death. There are two main types of stroke: brain ischemia, ischemic, due to lack of blood flow, and intracranial hemorrhage, hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly. Signs and symptoms of a stroke may include an hemiplegia, inability to move or feel on one side of the body, receptive aphasia, problems understanding or expressive aphasia, speaking, dizziness, or Homonymous hemianopsia, loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. A subarachnoid hemorrhage, hemorrhagic stroke may also be associated with a thunderclap headache, severe headache. The symptoms of a stroke can be permanent. Long-term complications may include pneumonia and Urinary incontin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
