Spatial Disorientation

There are five different kinds of spatial disorientation. These are all traceble to the cortex as well as the limbic system. Egocentric disorientation results from posterior parietal lesions and is associated with the inability in representing the locations of objects as associated with the person. Heading disorientation is characterized by the impairment of direction concerning the environment and is associated with lesions in the posterior cingulate cortex. In landmark agnosia the lesion is to be found in the lingual gyrus. This syndrome is characterized by the inability to the representation of important landmarks. Anterograde disorientation is associated with lesions of the parahippocampal gyrus and the patient in this condition is impaired in the aquisition of new facts about information of the environment. Finally, spatial mapping impairments is associated with hippocampal lesions and is associated with both anterograde and reterograde amne sia for enriched details in especially the spatial area (Kolb and Whishaw, 2008).
