Glossitis Geographic tongue, also termed benign migratory glossitis, is a common condition which usually affects the dorsal surface of the tongue. It is characterized by patches of depapillation and erythema bordered by a whitish peripheral zone. These patches give the tongue the appearance of a map, hence the name. Unlike glossitis due to nutritional deficiencies and anemia, the lesions of geographic tongue move around the tongue over time. This is because in geographic tongue, new areas of the tongue become involved with the condition whilst previously affected areas heal, giving the appearance of a moving lesion. The cause is unknown, and

It has been found that BPO errors (i.e. use of BPO pantomimes in place of the IO pantomimes dominant in typical adult individuals) are made by patients with schizophrenia. Given that BPO errors are associated with apraxia, and that past research has indicated that schizophrenic patients have apraxia-like symptoms, this is perhaps not a surprising finding. This BPO-schizophrenia association has not been extensively explored to date, and more research is required in order to better understand it. Body part as an object
