Role of the level of alertness. Based upon 25 new cases. The author, after referring to the leg muscle bed syndrome associated with exercise, reports the frequency of painful spasticity of the calves, occurring initially at rest and in particular at night in the form of a restless legs syndrome, then secondarily during the day with varying degrees of persistence at rest and during exercise. This problem frequently has a lateral dominance and appears to be induced by self-maintained functional muscular spasticity of the gastrocnemii and soleus, explained by a study. It is frequently attributed to a venous etiology. This study based upon 25 cases enabled definition of the diagnosis and showed the probable links between EMG hyperactivity and a high level of alertness indicative of a predisposing situation.

Antiepileptic drugs (AEDs) affect various neurotransmitters (i.e. GABA, glutamate), receptors (i.e. GABAergic, glutamatergic), and ion channels (i.e. for sodium or calcium) which is responsible for their anticonvulsant activity. However, this broad spectrum of action may be also utilized in other pathological conditions. For example, both conventional and newer AEDs may be used in patients suffering from neuropathic pain, migraine, essential tremor, spasticity, restless legs syndrome and a number of psychiatric disorders (f.e. bipolar disease or schizophrenia). Also, isolated data point to their potential use in Parkinson's or Alzheimer's disease. There is experimental background indicating a potent neuroprotective efficacy of AEDs in numerous models of brain ischemia. However, the clinical data are very limited and this problem requires careful assessment.

Treatment of multiple sclerosis (MS)-related fatigue is still a challenging task, given that no proven therapies exist and its mechanisms are not known. Our review highlights the relationship between MS-related fatigue and sleep disorders (SD). Although many studies suggest a higher overall prevalence of SD in MS, there are no valid and robust data to confirm this hypothesis until now except for restless legs syndrome (RLS): the prevalence of RLS in MS patients-especially in those with severe pyramidal and sensory disability-seems to be four times higher than in controls subjects. RLS is sometimes difficult to distinguish from spasticity and in case of doubt, probatory dopaminergic therapy or polysomnographic (PSG) investigations may be helpful. Nocturia may impact MS-related fatigue and should be considered. The treatment of underlying SD led to an improvement of MS-related fatigue. From a scientific point of view, SD should be examined in all studies investigating MS-related fatigue and be considered as a relevant confounder.

Cramps are painful sensations caused by intense involuntary contractions of skeletal muscles, mostly in the calves, usually lasting from a few seconds to several minutes. Although cramps are mostly idiopathic, theycan bea symptom of other forms of myalgia, restless legs syndrome or spasticity. Especially nocturnal cramps can cause considerable distress for patients requiring fast pain reduction and effective prophylaxis. Stretching the calf muscles helps preventing nocturnal cramps. Pharmacological treatment of leg cramps includes magnesium and quinine.

Mitochondrial disease presents with a wide spectrum of clinical manifestations that may appear at any age and cause multisystem dysfunction. A broad spectrum of movement disorders can manifest in mitochondrial diseases including ataxia, Parkinsonism, myoclonus, dystonia, choreoathetosis, spasticity, tremor, tic disorders and restless legs syndrome. There is marked heterogeneity of movement disorder phenotypes, even in patients with the same genetic mutation. Moreover, the advent of new technologies, such as next-generation sequencing, is likely to identify novel causative genes, expand the phenotype of known disease genes and improve the genetic diagnosis in these patients. Identification of the underlying genetic basis of the movement disorder is also a crucial step to allow for targeted therapies to be implemented as well as provide the basis for a better understanding of the molecular pathophysiology of the disease process. The aim of this review is to discuss the spectrum of movement disorders associated with mitochondrial disease.

Amyotrophic lateral sclerosis (ALS) is a progressive motor neuron disease inevitably leading to generalized muscle weakness and premature death. Sleep disturbances are extremely common in patients with ALS and substantially add to the burden of disease for both patients and caregivers. Disruption of sleep can be caused by physical symptoms, such as muscle cramps, pain, reduced mobility, spasticity, mucus retention, and restless legs syndrome. In addition, depression and anxiety may lead to significant insomnia. In a small subset of patients, rapid eye movement (REM) sleep behavioral disorder may be present, reflecting neurodegeneration of central nervous system pathways which are involved in REM sleep regulation. With regard to overall prognosis, sleep-disordered breathing (SDB) and nocturnal hypoventilation (NH) are of utmost importance, particularly because NH precedes respiratory failure. Timely mechanical ventilation is one of the most significant therapeutic measures to prolong life span in ALS, and transcutaneous capnometry is superior to pulse oxymetry to detect NH early. In addition, it has been shown that in patients on home ventilatory support, survival time depends on whether normocapnia, normoxia, and elimination of apneic events during sleep can be reliably achieved. Several studies have investigated sleep patterns and clinical determinants of sleep disruption in ALS, but exact prevalence numbers are unknown. Thus, constant awareness for sleep-related symptoms is appropriate. Since no curative treatment can be offered to affected patients, sleep complaints should be thoroughly investigated in order to identify any treatable etiology and improve or stabilize quality of life as much as possible. The use of hypnotics should be confined to palliation during the terminal phase and refractory insomnia in earlier stages of the disease, taking into account that most compounds potentially aggravate SDB.
