Though it is not possible for a definitive diagnosis of sexsomnia, a series of factors are considered to determine the presence of the condition. Clinical tests may also be utilized for further study. Determining factors Determining factors include but are not limited to: * a family history of somnambulism, or<unk> walking * prior episodes of somnambulism * disorientation when awoken * observed confusional or autonomic behavior * amnesia of episode * trigger factors the individual possesses * lack of regard to conceal episode * the nature of event compared to the individual's baseline character Clinical tests 365x365px Electroencephalography Electroencephalograms, or EEG, are tests used to depict electrical activity and waves produced by the brain. This test has the ability to detect abnormalities that are associated with disorders that affect brain activity. Episodes of sexsomnia occur most commonly during slow-wave-sleep, or SWS. During this stage of<unk> , brain waves tend to slow down and become larger. Through the use of electroencephalography, health professionals are able to determine if the sexual behaviors are occurring during non-REM<unk>  or if the individual is fully conscious. Polysomnography Polysomnography is a study conducted while the individual being observed is<unk> . A polysomnograph (PSG) is a recording of an individual's body functions as they<unk> . Specialized electrodes and monitors are connected to the individual and remain in place throughout study. Video cameras can be used to record physical behaviors that occur while the subject is<unk> . Typically, the unwanted sexual behaviors do not present on film and the majority of information is taken from a<unk>  study. The image above depicts an individual undergoing a<unk>  study. A PSG cannot determine a diagnosis every time it is performed, but can assist in determining what diagnoses should be considered or excluded. While PSG is a useful diagnostic tool, it cannot replace forensic examination. A PSG study may identify sexsomnia, but cannot determine whether it was responsible for an individual's actions or present during the time of an alleged crime. Likewise, the study may not identify sexsomnia, but that does not mean that the patient has never experienced it, so it is essential to collect information from as many sources as possible. This could include interviews with friends, family, and significant others, as well as medical records concerning the individual's<unk>  previous patterns. Polysomnography is also used in the diagnosis of other<unk>  disorders such as obstructive<unk>  apnea, narcolepsy, and restless leg syndrome. Body functions measured by a PSG * inspiratory and expiratory air flow * oxygen saturation in blood * respiratory effort * respiratory rate * eye movements * brain waves * electrical activity in muscles * position of body
