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
Cause of obsessive-compulsive disorder OCD in a Han Chinese population and found that one SNP, rs10491734, was significantly more frequent in OCD patients than in controls. However, the exact SNPs identified in the different studies vary, though it is possible that this is because the studies were conducted on different ethnic populations. For example, a family-based association study analyzed the instances of SNPs in and around SLC1A1 in families from throughout the US and found that a different SNP, rs4740788, and a 3-SNP haplotype, rs4740788-rs10491734-rs10491733, were both related to OCD. Several mouse models have been developed for the study of obsessive-compulsive disorder. Model organisms
