Many patients with epilepsy complain of decreased energy and somnolence. There is increased awareness that comorbidity, especially depression, plays an important role in determining the quality of life for patients with epilepsy. We set out to determine how subjective somnolence is affected by depression, age, hours of sleep, sleep apnea, seizure frequency, and numbers of antiepileptic drugs and central nervous system drugs. A questionnaire and chart review were used to investigate patients in a tertiary referral center. We found that subjective somnolence was prominent and that it relates mainly to depression, less to obstructive sleep apnea, and not to the other variables. Further investigation is needed into the relationship between depression and subjective somnolence in patients with epilepsy.

The authors present a pediatric case of ganglioglioma occurring in the medulla oblongata. A 7-year-old boy was referred to our hospital with complaints of ataxia, seizure and sleep apnea. MRI of the brain disclosed a large tumor occupying the medulla oblongata, and the upper portion of the cervical spinal cord was also involved. The patient underwent midline suboccipital craniotomy and laminectomy of C1 to attempt radical resection of the tumor, which resulted only in partial removal of the tumor due to severe bradycardia during the operation. The histological diagnosis was ganglioglioma, WHO grade 2. Although both radiotherapy and chemotherapy were performed following the operation, the tumor remained unchanged. The patient died of respiratory arrest five months after the operation. Gangliogliomas usually occur in the supratentorial region, which permits easy surgical access and good prognosis. Only 3% of gangliogliomas occur in the brain stem, and its management can be challenging because of the difficulty of radical resection and poor response to both radiotherapy and chemotherapy.

Vagus nerve stimulation (VNS) is an acceptable and effective adjunctive therapy for pharmacoresistant epilepsy. It is generally well tolerated and the most frequent side effects reported include respiratory dysfunction. We report the case of a female patient with intractable epilepsy who was implanted with the device and achieved a significant reduction in the number of her seizures. However, she developed central-type sleep apnea documented polysomnographically. Upon reduction of her VNS parameters, the apnea resolved and her sleep study reverted to normal. To our knowledge, this is the first case reported with polysomnographic evidence of VNS induction of central-type sleep apnea.

Patients with epilepsy were reported to have concomitant sleep apnea, but it has been rarely linked to the epilepsy itself. We present a case of a 28-year-old, obese man with secondary medically resistant partial complex epilepsy due to a brain trauma, with progressive snoring, and sleep agitation, apneas, and important daytime somnolence. It was noticed in the polysomnographic study that he had several sleep respiratory events, probably due both to the epileptic seizures and the sleep apnea syndrome as a co-morbidity. Apnea and epilepsy will be discussed. A careful video-EEG-polysomnography study is important in evaluating refractory epileptic patients and/or epileptic patients with snoring.

Following the decision in the Gillet Case it may no longer be safe to rely on the Austroads guidelines when considering fitness to drive. This paper examines the case and its implications. Although the Guidelines claimed '... the identification and application of world best-practice...', they were disregarded by the court in Gillet. Both expert witnesses testified that on disclosure of epilepsy the accused would have been endorsed as fit for a licence application to the Roads & Traffic Authority, on the basis of 10 years of only nocturnal seizures, in accordance with the guidelines. The Court rejected this evidence and interpreted failure to disclose epilepsy as recognition of perceived risk and the previously undiagnosed sleep apnoea as the basis for that risk, despite being diagnosed after the accident. There needs to be greater certainty in the application of the guidelines, with legislative intervention and licenses should display a bold statement advising drivers of their responsibility to notify authorities of illnesses that could potentially affect driving.

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.

Associations between obstructive sleep apnea and motor speech disorders in adults have been suggested, though little has been written about possible effects of sleep apnea on speech acquisition in children with motor speech disorders. This report details the medical and speech history of a nonverbal child with seizures and severe apraxia of speech. For 6 years, he made no functional gains in speech production, despite intensive speech therapy. After tonsillectomy for obstructive sleep apnea at age 6 years, he experienced a reduction in seizures and rapid growth in speech production. The findings support a relationship between obstructive sleep apnea and childhood apraxia of speech. The rather late diagnosis and treatment of obstructive sleep apnea, especially in light of what was such a life-altering outcome (gaining functional speech), has significant implications. Most speech sounds develop during ages 2-5 years, which is also the peak time of occurrence of adenotonsillar hypertrophy and childhood obstructive sleep apnea. Hence it is important to establish definitive diagnoses, and to consider early and more aggressive treatments for obstructive sleep apnea, in children with motor speech disorders.

Hunter disease (mucopolysaccharidosis type II, MPS II) is an X-linked lysosomal storage disease caused by deficiency of iduronate-2-sulfatase. Accumulation of chondroitin sulfate B and heparan sulfate in various tissues is the biochemical consequence of MPS II. Children with Hunter disease are normal at birth, and symptoms occur between 2 and 10 years of age. Typical symptoms include coarse facies with enlarged tongue and prominent forehead as well as a short, stocky built stature with short neck. The cardiovascular, respiratory and gastrointestinal systems may be affected, and oral, dermatological and psychiatric as well as neurological complications are described. Life expectancy is markedly reduced and may be limited to 12 years for severely affected patients. The most common causes of death are airway obstruction and cardiac failure. The most severe symptoms may result from neurological symptoms or complications including hydrocephalus, spinal cord compression, cervical myelopathy, optic nerve compression, and hearing impairment. Patients may also develop carpal tunnel syndrome, sleep apnoea, seizures or mental retardation. This review describes characteristic neurological manifestations in MPS II and its underlying pathophysiology. In addition, an appraisal is given whether or not enzyme replacement therapy may be able to improve in particular the neurological symptoms of Hunter disease.

Stroke in the elderly has more major differences compared to young people: it is the first complication of atherothrombosis disease associated with the following risk factors: hypertension, diabetes, hypercholesterolemia, tobacco consumption and sleep apnea syndrome; AVC is the first consequence of atrial fibrillation; from a clinical point of view, seizure at the onset of the stroke is more frequent; prognosis is characterized by a high risk of dementia (20%); primary and secondary prevention is very efficacious even in very old patients, not only on the risk of stroke, but also on the risk of dementia; time trends at Dijon show a slight decrease of incidence rates of stroke only over 85 years, while prevention of stroke has taken advantage of real progress in precocious diagnosis and innovative treatments. In contrast, we observed a decrease of case-fatality rates at any day with a delay in age of onset of stroke, reaching five years in men and eight years in women, suggesting an increase of life expectancy without stroke, reflecting a certain efficacy of prevention.

An observational study of cases of obstructive sleep apnoea-hypopnoea syndrome (OSAHS), both suspected and established, presenting to general neurology outpatient clinics over a 5-year period was undertaken. Only eight new cases of OSAHS, confirmed by sleep studies, were identified, most with neurological problems (poor seizure control, blackouts and headache) in addition to excessive daytime somnolence. OSAHS appears to be a rare cause of new symptomatic neurological presentations, although cases may have been overlooked as judgement was based on the index of clinical suspicion alone.
