review of the possible relationship and hypothetical links between attention deficit hyperactivity Disorder adhd and the simple sleep related Movement Disorders parasomnias hypersomnias and circadian rhythm Disorders
Journal of Clinical Sleep Medicine, 2008Co-Authors: Arthur S Walters, R Silvestri, Marco Zucconi, Ranju Chandrashekariah, Eric KonofalAbstract:Recent evidence has been accumulating that the sleep of individuals with attention deficit hyperactivity Disorder (ADHD) is not only disrupt- ed in a nonspecific way but that ADHD has an increased association with simple sleep related Movement Disorders such as restless legs syndrome/periodic limb Movements in sleep (RLS/PLMS), Rhythmic Movement Disorder (body rocking and head banging), and parasom- nias, such as Disorders of partial arousal (sleep walking, sleep ter- rors, and confusional arousals). In addition increased associations have been reported between ADHD and hypersomnias such as nar- colepsy and sleep apnea as well as circadian rhythm Disorders, such as delayed sleep phase syndrome. These relationships are reviewed and the implications for such associations are explored. Patients with sleep Disorders should be queried about the symptoms of ADHD and vice versa.

simple sleep related Movement Disorders of childhood including benign sleep myoclonus of infancy Rhythmic Movement Disorder and childhood restless legs syndrome and periodic limb Movements in sleep
Sleep Medicine Clinics, 2007Co-Authors: Arthur S WaltersAbstract:The simple sleep-related Movement Disorders of childhood must be distinguished from childhood parasomnias. The simple sleep-related Movement Disorders are usually monophasic and do not seem to be goal directed. The parasomnias are often complex and seem to be goal directed, but the behavior is inappropriate and outside the conscious awareness of the individual. The simple sleep-related Movement Disorders of childhood include benign sleep myoclonus of infancy, Rhythmic Movement Disorder, and childhood restless legs syndrome and periodic limb Movement Disorder in sleep.

Parasomnia Overlap Disorder: RBD and NREM Parasomnias
Rapid-Eye-Movement Sleep Behavior Disorder, 2018Co-Authors: Carlos H. Schenck, Michael J HowellAbstract:Parasomnia overlap Disorder (POD) was formally described and named in 1997 with a series of 33 cases of RBD combined with a Disorder of arousal from NREM sleep (confusional arousals, sleepwalking, sleep terrors) that emerged idiopathically or symptomatically with neurological and other Disorders. The presenting complaint was sleep-related injury; mean age was 34 years, and mean age of parasomnia onset was 15 years (range 1–66 years); 70% were males. POD is classified as a subtype of RBD in the International Classification of Sleep Disorders, 3rd edition. An updated classification of POD also includes RBD-sleep-related eating Disorder, RBD-sexsomnia, RBD-Rhythmic Movement Disorder, and POD with Parkinson’s disease and other neurological Disorders, including the newly identified autoimmune tauopathy with antibodies against IgLON5 (“anti-IgLON5 syndrome”) manifesting as RBD, NREM parasomnia, sleep-related breathing disturbance and striking, and progressive neurological features. POD may be a distinct pathophysiological entity, and not just a variant of RBD, given its typically younger age of onset and apparent lack of progression to neurodegeneration that contrasts with typical RBD in middle-aged and older adults. POD is usually controlled with bedtime clonazepam and other therapies.

Spectrum of rapid eye Movement sleep behavior Disorder (overlap between rapid eye Movement sleep behavior Disorder and other parasomnias)
Sleep and Biological Rhythms, 2013Co-Authors: Carlos H. Schenck, Michael J HowellAbstract:Parasomnia Overlap Disorder (POD) was described and named in 1997 with a series of 33 cases of rapid eye Movement (REM) sleep behavior Disorder (RBD) combined with a Disorder of arousal from non-rapid eye Movement (NREM) sleep (sleepwalking, sleep terrors) that emerged idiopathically or symptomatically with neurological and other Disorders. POD is a subtype of RBD in the International Classification of Sleep Disorders Diagnostic and Coding Manual , second edition (ICSD-2). An updated classification of POD also includes subclinical RBD-NREM parasomnia, RBD-sleep-related eating Disorder, RBD-sexsomnia, RBD-Rhythmic Movement Disorder, and status dissociatus (SD), which is another subtype of RBD in the ICSD-2. Similar to POD, a core feature of SD is sleep motor-behavioral dyscontrol, with release of dream-related behaviors suggestive of RBD, but with nearly continuous ambiguous polygraphic sleep precluding the identification of NREM/REM sleep states. SD exemplifies extreme state dissociation. SD is always a symptomatic Disorder, and is causally associated with a broad range of neurologic Disorders, often with thalamic, limbic, striatal, and pontine involvement. The parasomnia behaviors associated with POD and SD — typical RBD behaviors — can often be controlled with bedtime clonazepam therapy, including the abnormal dreaming.

sleep related Rhythmic Movement Disorder revisited
Journal of Sleep Research, 2007Co-Authors: Geert Mayer, Johanna Wildefrenz, Brigitte KurellaAbstract:Summary To classify sleep related Rhythmic Movement Disorder (SRMD) based on clinical, polysomnographic and videometric evaluation in a predominantly adult population, twenty-four patients (four females) aged 11–67 years identified by polysomnography and videometry were classified for type of SRMD, its duration and frequency during wakefulness and in the different sleep stages. SRMD persisted unto child- and adulthood in all patients. SRMD is not restricted to sleep-wake transition, occurs most frequently in wake, stages NREM 1 and 2, but also in REM and slow wave sleep. Most patients have one form of SRMD, few have two forms in one night. Longest duration is in wakefulness. Duration does not differ from one sleep cycle to another. Sleep is not fragmented by SRMD, and sleep stages generally do not change when SRMD occurs. Only few patients have short awakenings after SRMD. In four patients with sleep apnea SRMD coincided frequently with the onset of the apnea related arousal. Two patients had a family history of SRMD. In contrast to the ICSD-2 SRMD seems to persist into adulthood frequently with male preponderance. Familial forms are rare. SRMD in the investigated population is always occurring during sleep, even if patients reported it to occur strictly at wake-sleep transition. Polysomnography is a useful method to uncover SRMD aggravated by other sleep Disorders and allows insight in some aspects of the pathology of this Disorder, which is not well understood. In the adult patients it is not associated with mental pathologies and can be triggered by sleep apnea.

Parasomnias associated with sleep-Disordered breathing and its therapy, including sexsomnia as a recently recognized parasomnia
Somnologie - Schlafforschung und Schlafmedizin, 2008Co-Authors: Carlos H. Schenck, Mark W. MahowaldAbstract:Parasomnias are defined in the International Classification of Sleep Disorders-2nd Edition (ICSD-2) as undesirable physical events or experiences that occur during entry into sleep, within sleep, or during arousals from sleep. Instinctual behaviors can inappropriately emerge with the parasomnias, including appetite behaviors (feeding, sex), locomotion, aggression, and violence. Sleep Disorders and their therapies carry their own risk for parasomnias, including sleep-Disordered breathing (SDB) and its therapy with nCPAP. A Pub Med literature search was conducted for peer-reviewed journal articles with key words "parasomnia" (and other specific parasomnias) linked with "sleep apnea" or "sleep Disordered breathing." Eight of the 12 parasomnias found in the ICSD-2 are associated with SDB, along with 3 of the 4 parasomnia variants in ICSD-2, for a total of 11 of 16 (68.7 %) parasomnias and their variants being associated with SDB. The list of parasomnias includes confusional arousals (and its variants, severe morning sleep inertia, and sleep related abnormal sexual behaviors [sexsomnia, sleepsex]); sleepwalking; sleep terrors; sleep related eating Disorder; REM sleep behavior Disorder (and "OSA pseudo RBD"); parasomnia overlap Disorder (RBD combined with a Disorder of arousal); nightmare Disorder; sleep related groaning (catathrenia); and sleep enuresis. Sleep Related Movement Disorders include sleep related bruxism and sleep related Rhythmic Movement Disorder. Other conditions include gastrooesophageal reflux Disorder with sleep related laryngospasm; cerebral anoxic attacks; nocturnal seizures (Complex Partial Seizures; Nocturnal Frontal Lobe Epilepsy); sleep related anxiety reactions and panic attacks; chronic hiccups; and sleep choking syndrome. A case report is included of a man with moderately severe OSA and with recurrent, unconscious sexsomnia with his wife, who fully responded to nCPAP therapy that normalized his SDB and complete ly eliminated the sexsomnia, which presumably had emerged during OSA confusional arousals. A current classification of sexsomnia, a recently recognized parasomnia variant, is reviewed, along with comments on OSA-sexsomnia.
