Doctors will do a multiple sleep latency test, which measures how long it takes a person to fall asleep.Sleep apnea, when breathing repeatedly stops and starts during sleep, can be a serious sleep disorder. Three types of sleep apnea include obstructive sleep apnea, central sleep apnea, and complex sleep apnea. Sleep apnea can be diagnosed at home or with polysomnography at a sleep center. An ear, nose, and throat doctor may further help with the sleeping habits. Sexuality related
Sexual disorders include dyspareunia and various kinds of paraphilia (sexual arousal to objects, situations, or individuals that are considered abnormal or harmful to the person or others). Other
Impulse control disorder: People who are abnormally unable to resist certain urges or impulses that could be harmful to themselves or others, may be classified as having an impulse control disorder, and disorders such as kleptomania (stealing) or pyromania (fire-setting). Various behavioral addictions, such as gambling addiction, may be classed as a disorder. Obsessive-compulsive disorder can sometimes involve an inability to resist certain acts but is classed separately as being primarily an anxiety disorder. Substance use disorder: This disorder refers to the use of drugs (legal or illegal, including alcohol) that persists despite significant problems or harm related to its use. Substance dependence and substance abuse fall under this umbrella category in the DSM. Substance use disorder may be due to a pattern of compulsive and repetitive use of a drug that results in tolerance to its effects and withdrawal symptoms when use is reduced or stopped.
His hallucinations consisted of perceptions of men, women, birds, carriages, buildings, tapestries, physically impossible circumstances and scaffolding patterns. Even though his health was in good shape and he had an absence of any psychiatric disorders, the source of the hallucinations remained unknown. At forty years old, Charles Bonnet himself suffered from an unrevealed cause of severe vision loss and experienced the hallucinations.In 1936, Jean Lhermitte and Julian de Ajuriaguerra, concluded that visual hallucinations consist of thalamic lesions as well as ocular pathology.In 1967, French-Swiss neurologist, Georges de Morsier, coined the term Charles Bonnet Syndrome in Bonnets honor. De Morsier’s description of CBS implies a concentrated neurodegeneration, usually occurring in the elderly with typical cognition. In psychiatric literature, the most commonly accepted interpretation of CBS is that of Gold and Rabins’. In 1989, they detailed that the hallucinations associated with CBS are not affecting other sensory modalities. They believed that the visual hallucinations are oftentimes stereotyped, persistent, and/or repetitive in nature. Society and culture
