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 Cause of obsessive-compulsive disorder The cause of obsessive-compulsive disorder is concerned with identifying the biological risk factors involved in the expression of obsessive-compulsive disorder (OCD) symptomology. The leading hypotheses propose the involvement of the orbitofrontal cortex, basal ganglia, and/or the limbic system, with discoveries being made in the fields of neuroanatomy, neurochemistry, neuroimmunology, neurogenetics, and neuroethology. Although there has been substantial debate regarding the assessment of DCO, current research has gravitated toward structural and functional neuroimaging. These technological innovations have provided a better understanding of the neuroanatomical risk factors of OCD. These studies can be divided into four basic categories:
