Parasomnias are undesirable behavioral or experiential phenomena arising from the sleep period. Once felt to be a unitary phenomenon, it is now clear that a wide variety of sleep disorders are capable of resulting in complex behaviors arising during sleep. The most common are disorders of arousal and rapid eye movement sleep disorder. Less common conditions include nocturnal seizures and psychogenic dissociative states. Malingering and Munchausen syndrome by proxy, while they are not actually parasomnias, may masquerade as parasomnias. Careful clinical and sleep laboratory evaluation can usually provide an accurate diagnosis with effective therapeutic implications. Due to the potential forensic implications, sleep medicine specialists may be asked to participate in legal proceedings resulting from sleep-related violence. An awareness of the spectrum of such behaviors, and their clinical and legal evaluation, is becoming more important in the practice of sleep medicine.

A sleep history should be taken routinely in patients with epilepsy. Treatment of sleep disorders and improvement in sleep hygiene may improve seizure control, daytime cognitive functioning, and quality of life. Patients with recurrent sleepiness interfering with daily activities or an Epworth Sleepiness Scale score more than 10 should be considered for additional evaluation by a sleep specialist. Treatment options for insomnia include improvements in sleep hygiene, cognitive behavior therapies, and sedative or hypnotic drugs. Alterations in the timing or type of antiepileptic drugs (AEDs) may be helpful (for example, using sedating medications before bedtime and avoiding evening use of drugs that may exacerbate insomnia ). Improvements in sleep hygiene alone are less effective than cognitive behavioral therapy or pharmacologic therapy. Cognitive behavioral therapy is more efficacious and its effects longer lasting than pharmacologic treatments. Sedative and hypnotic drugs may exacerbate AED cognitive adverse effects during the day and should be used only after other therapies have failed. Excessive daytime sleepiness (EDS) in patients with epilepsy may be secondary to AEDs, nocturnal seizures, or a concomitant sleep disorder such as sleep apnea or restless leg syndrome. Sedating AEDs should be minimized during the day, and activating AEDs should be used as appropriate. Video electroencephalogram polysomnography should be performed when EDS interferes with daily activities and the etiology of sleepiness is unclear. AEDs that are associated with weight gain should be avoided in patients with sleep apnea. AEDs that may promote weight loss should be considered for obese patients with sleep apnea. Continuous positive airway pressure is the treatment of choice for sleep apnea.

The diagnosis of paroxysmal events in sleep represents a significant challenge for the clinician, with the distinction of nocturnal epilepsy from nonepileptic sleep disorders often the primary concern. Diagnostic error or uncertainty is not uncommon in this situation, particularly with respect to nocturnal frontal lobe epilepsy (NFLE), which has a variable and often unusual presentation. Such errors can be minimized if the range of nonepileptic disorders with motor activity in sleep is fully appreciated. Here we review these disorders, before discussing the important clinical and electrographic features that allow their accurate differentiation from seizures. Particular emphasis is placed on the differentiation of nocturnal frontal lobe epilepsy from non-rapid eye movement (NREM) arousal disorders and other parasomnias. The value of recording episodes with video EEG polysomnography is discussed.

Panayiotopoulos syndrome is a relatively frequent and benign epileptic syndrome, characterised by predominantly autonomic symptoms and/or simple motor focal seizures followed or not by impairment of consciousness. Interictal EEG shows occipital spikes although multifocal spikes with high amplitude sharp-slow wave complexes at various locations can be present. This syndrome can imitate gastroenteritis, encephalitis, syncope, migraine, sleep disorders or metabolic diseases. The peculiar aspects should be known not only by epileptologists but also by general doctors because a correct diagnosis would avoid aggressive interventions and concerns on account of its benign outcome. This review focuses on the main clinical and EEG features of this epilepsy underlining its typical and atypical symptoms and its management.

During a viewing of Disney's animated film Cinderella (1950), one author (AI) noticed a dog having nightmares with dream-enactment that strongly resembled RBD. This prompted a study in which all Disney classic full-length animated films and shorts were analyzed for other examples of RBD. Three additional dogs were found with presumed RBD in the classic films Lady and the Tramp (1955) and The Fox and the Hound (1981), and in the short Pluto's Judgment Day (1935). These dogs were elderly males who would pant, whine, snuffle, howl, laugh, paddle, kick, and propel themselves while dreaming that they were chasing someone or running away. In Lady and the Tramp the dog was also losing both his sense of smell and his memory, two associated features of human RBD. These four films were released before RBD was first formally described in humans and dogs. In addition, systematic viewing of the Disney films identified a broad range of sleep disorders, including nightmares, sleepwalking, sleep related seizures, disruptive snoring, excessive daytime sleepiness, insomnia and circadian rhythm sleep disorder. These sleep disorders were inserted as comic elements. The inclusion of a broad range of accurately depicted sleep disorders in these films indicates that the Disney screenwriters were astute observers of sleep and its disorders.

In this paper we explore the prevalence of ictal and interictal epileptiform discharges (IEDs) and sleep disorders in ADHD children referred to a sleep clinic for all night video-PSG. Forty-two ADHD outpatients (35 males and 7 females) underwent video-PSG and a behavioural/neuropsychological assessment. Spearman correlation coefficients (p<0.05 criterion level) were used to assess the association between cognitive, behavioural, clinical (co-morbidity), sleep (sleep efficiency) and EEG (seizures, IEDs, localization of IEDs foci) variables. Sleep disorders were found in 86% of ADHD children; among these, 26% had RLS. 53.1% of ADHD children had IEDs (28.2% centro-temporal spikes, 12.5% frontal spikes, 9.3% temporal-occipital spikes and 2.3% generalized S-W). Nocturnal seizures were recorded in three patients: two with atypical interictal rolandic spikes and one with left frontal slow abnormalities. A significant relationship (p<0.05) emerges between nocturnal seizures and WISC-R IQ score and visual-spatial memory test and between some cognitive variables and interictal rolandic spikes. High levels of inattention, impulsivity/hyperactivity and oppositional behaviours were related (p<0.01 or 0.05) with Restless Leg Syndrome diagnosis. In conclusion, ADHD is a condition often associated with EEG epileptiform abnormalities. Seizures/IEDs presence seems to play a role on cognitive abilities, conversely sleep disorders have a stronger impact on behavioural rather than cognitive indicators.

Sleep disorders are common in childhood. The prevalence of childhood sleep disorders is higher in chronic neurologic disorders, specifically epilepsy. Sleep needs, requirements, and structure are different in children compared with adults. These variables are disrupted severely in patients with epilepsy. Electroencephalogram abnormalities, nocturnal seizures, and medications may contribute further to sleep problems and affect daytime functioning. These sleep disturbances may worsen seizure control and affect quality of life. This article offers an overview of the normal sleep patterns in children, describes the interaction of electroencephalogram, sleep, and commonly found sleep disorders, and reviews the current literature of the main sleep disturbances found in children with epilepsy.

Vagus nerve stimulation (VNS) is an established treatment for selected patients with medically refractory seizures. Recent studies suggest that VNS could be potentially useful in the treatment of resistant depressive disorder. Although a surgical procedure is required in order to implant the VNS device, the possibility of a long-term benefit largely free of severe side effects could give VNS a privileged place in the management of resistant depression. In addition, VNS appears to affect pain perception in depressed adults; a possible role of VNS in the treatment of severe refractory headache, intractable chronic migraine and cluster headache has also been suggested. VNS is currently investigated in clinical studies, as a potential treatment for essential tremor, cognitive deficits in Alzheimer's disease, anxiety disorders, and bulimia. Finally, other studies explore the potential use of VNS in the treatment of resistant obesity, addictions, sleep disorders, narcolepsy, coma and memory and learning deficits.

Sleep and epilepsy are interrelated. Understanding the relationship between epilepsy and sleep is important for optimizing management of the epilepsy patient in several ways. First, sleep modulates the expression of epileptic seizures and interictal epileptiform discharges. Second, epilepsy and its treatment influence sleep organization and daytime alertness, and may contribute to, or ameliorate, sleep disorders. Finally, treatment of a coexisting sleep disorder may improve seizure control, daytime alertness, and health-related quality of life. In this article, aspects related to the interrelationship of sleep and epilepsy will be discussed and the model of how sleep can interact with a neurological disorder will be illustrated.

The frequency of sleep disturbances in patients with epilepsy and their impact on quality of life (QoL) have been documented in a few reports, and the results are conflicting. We identified 124 consecutive epilepsy out-patients who visited the epilepsy out-patient clinics at the University Hospital of Alexandroupolis, the AHEPA Hospital in Thessaloniki and the Aeginitio Hospital in Athens. We measured excessive daytime sleepiness (EDS) with the Epworth Sleepiness Scale (ESS), obstructive sleep apnea (OSA) with the Sleep Apnea scale of the Sleep Disorders Questionnaire (SA-SDQ), and insomnia with the Athens Insomnia Scale (AIS). We evaluated quality of life by the Quality of Life in Epilepsy Inventory (QOLIE-31). EDS was found in 16.9% (21/124) of epileptic patients, OSA in 28.2% (35/124), and insomnia in 24.6% (30/122). In multivariate analysis, we found that insomnia was an independent negative factor for Total score (p<0.001), Overall QoL (p=0.002), Emotional well-being (p<0.001), Energy/fatigue (p<0.001), Cognitive functioning (p=0.04) and Social functioning (p=0.03), and OSA only for Cognitive functioning (p=0.01). According to our findings, EDS, OSA, and insomnia are frequent in epileptic patients. Epileptic patients with sleep disturbance, mainly insomnia, have significant QoL impairment.
