Nose-picking and burping. Mucophagy, which is eating the extracted mucus, may be considered more taboo, and is sometimes portrayed in comedies. To be caught nose-picking may be considered humiliating. When nose picking becomes a body-focused repetitive behavior or obsessive–compulsive disorder it is known as rhinotillexomania. Most cases do not meet this pathological threshold. When it does, however, treatments similar to other BFRBs can be employed. The environment of the nose and the dried secretions removed contain many microorganisms. When a person is contagious with a cold, flu or other virus, it is important that hands or other objects used to remove
Biology of obsessive–compulsive disorder Biology of obsessive–compulsive disorder The biology of obsessive-compulsive disorder(OCD) refers biologically based theories about the mechanism of OCD. Cognitive models generally fall into the category of executive dysfunction or modulatory control. Neuroanatomically, functional and structural neuroimaging studies implicate the prefrontal cortex (PFC), basal ganglia (BG), insula, and posterior cingulate cortex (PCC). Genetic and neurochemical studies implicate glutamate and monoamine neurotransmitters. The cortico-basal ganglia-thalamo-cortical loop (CBGTC) model is based on the observation that the basal ganglia loops related to the OFC and ACC are implicated in OCD by neuroimaging studies, although the directionality of volumetric and functional changes is not consistent.
