This review describes the wide spectrum of paroxysmal events during sleep in infancy and childhood. The differential diagnosis between sleep-related non-epileptic paroxysmal events and epileptic seizures is difficult in special occasions. The nocturnal frontal lobe seizure and of the more common non- epileptic paroxysmal events during sleep are described. The main differentiating features characterizing parasomnias are: onset in early childhood, rare episodes of long duration, relatively lower frequency per night, absence of stereotypy, gradual disappearance of older age. Video-polysomnography is the gold standard to diagnosing and differentiating parasomnias from nocturnal frontal lobe seizures.

We report adult-onset sleep terrors in a patient with idiopathic Parkinson's disease. A 42-year-old woman presented with abnormal behaviors during sleep. Neurologic examination revealed mild hypomimia, resting tremor and bradykinesia in her right upper limb indicating early Parkinson's disease. An episode would consist of sitting up in bed, screaming, then clapping her hands and more talking, shouting, screaming, and appearing frightened. Polysomnography documented 2 episodes of parasomnia which occurred in slow wave sleep indicating sleep terrors.

Nocturnal panic involves sudden awakening from sleep in a state of panic characterized by various somatic sensation of sympathetic arousal and intense fear. Many(18-71%) of the spontaneous panic attacks tend to occur from a sleeping state unrelated to the situational and cognitive context. Nocturnal panickers experienced daytime panics and general somatic sensation more frequently than other panickers. Despite frequent distressing symptoms, these patients tend to exhibit little social or occupational impairment and minimal agoraphobia and have a high lifetime incidence of major depression and a good response to tricyclic antidepressants. Sleep panic attacks arise from non-REM sleep, late stage 2 or early stage 3. The pathophysiology and the similarity of nocturnal panic to sleep apnea, dream-induced anxiety attacks, night terrors, sleep paralysis, and temporal lobe epilepsy are discussed.

PURPOSE: To investigate the frequency of childhood sleep problems at pediatric clinics in Seoul and Gyeonggi provinces. METHODS: Children (n=936) and their parents who visited 5 primary and 1 secondary pediatric outpatient clinics were invited to complete a Pediatric Sleep Questionnaire. RESULTS: Among patients, 901 (96.3%) answered questionnaires in sufficient detail for evaluation. The participant's mean age was 4.35±3.02 years (range, 0–18 years). The male to female ratio was 1:0.93 (466 boys, 435 girls). Habitual snoring (>3 day/week) was reported in 16.9% of the participants. The prevalence of habitual snoring in children <2 years and those between 2–5 years was 9% and 18%, respectively. Sleep disordered breathing was found in 15.1% (106 of 700) of children >2 years. Insomnia was reported in 13.2% of children. The prevalence of sleepwalking, night terrors, and bruxism, is 1.6%, 19%, and 21.1%, respectively. Snoring was associated with increased incidence of sleepwalking, night terrors, and bruxism. Age was associated with insomnia and habitual snoring (P<0.05). Insomnia was more prevalent in younger (21%) than in older children (6%). Snoring was more frequent in both preschool (34%) and school-aged children (33%). The frequency of sleep disordered breathing and insomnia did not vary significantly with gender. However, snoring was more prevalent in boys. CONCLUSION: Sleep problems are frequent among children in Korea. Children with snoring have an increased risk of sleepwalking, night terror, and bruxism. Primary clinicians should consider children's sleep habits to improve their health.
