Parasomnias emerging from NREM sleep such as sleep walking, sleep terrors and confusional arousals are considered arousal disorders. Nocturnal video-polysomnography is the gold standard to diagnosing and differentiating parasomnias from other arousals with atypical motor behaviors such as nocturnal frontal lobe epilepsy (NFLE). This form of nocturnal seizures with prominent dystonic-dyskinetic components, in some cases genetic, has been recently identified by means of detailed video-analysis of movements during sleep. The clinical picture of parasomnias (with onset in early childhood, rare episodes of long duration, absence of stereotypy, general disappearance after puberty) is different from that of NFLE (which first occurs between the age of 10 and 20, manifests frequent complex and repetitive behaviors of short duration excluding rare prolonged seizures, nocturnal agitation, some daytime complaints such as fatigue or sleepiness, persistence into adulthood). Patients show no difference from classical sleep parameters whilst microstructure analysis shows sleep instability and arousal fluctuations in parasomnias and NFLE. In children as well, at least in our experience, the differential diagnosis between the two disorders is difficult and requires one or more complete nocturnal video-polygraphic recording. In any case the diagnosis of NFLE should be considered in children with nocturnal motor episodes or nocturnal motor agitation, when the attacks persist; this diagnosis is probably more frequent than expected.

Sleep disturbances are common in neurodegenerative diseases. Disturbed sleep can result in fatigue, irritability, morning headaches, impaired motor and cognitive skills, depression, and daytime somnolence. The major sleep complaints include: insomnia, hypersomnia, parasomnia, excessive nocturnal motor activity, circadian sleep-wake rhythm disturbance, and respiratory dysrhythmia. The pathogenetic mechanisms of sleep disturbances may be secondary to direct structural alteration of the sleep-wake generating neurons or from several other indirect mechanisms. At the biochemical level, neurodegenerative diseases may be largely classified as tauopathies, alpha-synucleinopathies, and other diseases. Overnight polysomnography (PSG) and multiple sleep latency test are the two most important diagnostic laboratory tests in the evaluation of sleep disturbances. Management of sleep disturbances is complex and is based primarily on the nature of the sleep disturbance. The clinical profiles, pathogenetic mechanisms, PSG findings, and management issues are discussed here with reference to some common neurodegenerative diseases.

Sleep-related disturbed breathing and parasomnia in very young children are in the focus of epidemiological interest. The cardinal symptom, i.e. snoring, in connection with nocturnal perspiration, mouth breathing, susceptibility to infection of the upper respiratory tract and tiredness during the day or hypermotility, can be an indication of obstructive sleep apnea (OSA). The common treatment is adenotomy unless there is indication of allergic swelling of the nasal mucous membrane. Other anatomic predispositions for OSA must be considered (tonsillar hypertrophy, midfacial hypoplasia, micro- and retrognathia, e.g. in patients with Down's syndrome or patients with preoperated cleft lip face palate). Inhalative nasal corticoids are a possible alternative to adenotomy in light to medium grade cases of OSA. Tonsillotomy is indicated only in serious OSA cases, tonsillectomy is only justified in cases of chronic tonsillitis or more than 4-6 cases of angina in the last 12 months. Treatment with nasal CPAP is tolerated well also in childhood. Patients with central hypoventilation syndromes, insufficiency of the respiratory musculature or obesitas hypoventilation syndrome can usually be ventilated by non-invasive approach using a nasal mask. Patients suffering from parasomnia should always be asked if they snore at night because if OSA is diagnosed and treated, there are very good prospects of curing somnambulism as well. Like with narcolepsy and REM sleep, a close HLA association has also been identified for family somnambulism. In cases of parasomnia which becomes manifest only after very young age frontal lobe epilepsy should be suspected and searched by polysomnographic and simultaneous continuous nocturnal video surveillance. If reversive development or unclear motoric and utterance phenomena are observed, sleep-bound convulsive disorder should be looked for. Syncopal events can require comprehensive cardiological diagnosis, including exclusion of nightly disorders of the cardiac rhythm.

The objective of the study was to provide further information related to newly described parasomnia variant, Sexual Behaviour in Sleep (SBS, sexsomnia). Previous studies dealt with selected population, typically middle-aged males, featuring extensive medico-legal exposure. At the same time, an anecdotal evidence suggested higher involvement of younger population, and skew towards balance between genders comparable to those seen in other non-Rapid Eye Movement (NREM) sleep parasomnias. The epidemiological information regarding this condition is still virtually non-existent. In order to sample this difficult-to-reach population, a 28-item Internet survey was posted on the sexsomnia reference site and the link was also sent to prospective respondents (mostly registered visitors to this site). The respondents were able to complete the survey anonymously, which resulted in a need for the screening of bogus and duplicate results. At the end, a total of 219 validated responses were collected and analysed. The results showed greater representation of females (31% of the total number), and wider age distribution (mean age of 30.4 years). The respondents typically reported multiple sexsomnia episodes, in most cases precipitated by body contact, stress and fatigue. Relatively small number of respondents reported involvement of legal authorities (8.6% of males and 3% of females) and participation of minors in their sexsomnia (6% of the total sample). In spite of known limitations of such surveys, the study provided much needed insight into this complex nocturnal behaviour. It confirmed the anecdotal evidence about the gender and age distribution, and provided information on some key features, such as precipitating factors, type of behaviour, medication use, personal medical history and medico-legal aspects.

Although sleep appears to be a quiescent, passive state externally, there are a multitude of physiological changes occurring during sleep that can affect cerebral homeostasis and predispose individuals to cerebrovascular disorders. Therefore, it is not surprising that sleep-disordered breathing causes significant nocturnal perturbations, such as obstructive sleep apnea (OSA), that can lead to cerebrovascular disorders. There is evidence to suggest that OSA is a risk factor for stroke, although studies have not been able to clearly discern the absence or presence of OSA before the stroke event. Sleep-disordered breathing, such as OSA and central sleep apnea, can occur as a consequence of stroke. Fortunately, treating OSA appears to decrease morbidity and possibly mortality. Unfortunately, continuous positive airway pressure compliance in this population group is low, and significant efforts and resources may be needed to improve compliance and adherence. Various other sleep disorders, such as insomnia, fatigue, hypersomnia, and parasomnia, can occur following a stroke, and physicians treating patients following a stroke need to be aware of these disorders in order to effectively treat such patients.

Jactatio corporis nocturna is a type of parasomnia. Rhythmic body movements during sleep are commonly observed in infancy and early childhood, and spontaneous resolution is expected after the age of 4 years. Rarely, the body movements persist until adulthood. Rhythmic body movements characteristically occur during the wake-sleep transition period, rather than during other sleep stages. Some psychiatric diseases can co-occur with sleep-related movement disorders. A relationship between parasomnias and dissociative disorders has been recently reported. Herein we present a 33-year-old male with nocturnal repetitive rolling body movements and daytime fatigue. The patient also had loss of memory of some important events (such as the day his daughter underwent surgery), and reported that he sometimes confused reality with dreams had fantasies during which he experienced his spirit rising above to watch his body and fantasy. Detailed neuropsychological assessment showed that the patient also had a dissociative disorder. Video-polysomnographic recordings showed repetitive, rolling body movements that occurred only during rapid eye movement (REM) sleep.
