The term fatigue is used to describe a distressing and persistent symptom of physical and/or mental tiredness in certain clinical populations, with distinct but ultimately complex, multifactorial and heterogenous pathophysiology. Chronic fatigue impacts on quality of life, reduces the capacity to perform activities of daily living, and is typically measured using subjective self-report tools. Fatigue also refers to an acute reduction in the ability to produce maximal force or power due to exercise. The classical measurement of exercise-induced fatigue involves neuromuscular assessments before and after a fatiguing task...

Multiple sclerosis (MS) is a chronic inflammatory and neurodegenerative disease of the central nervous system, characterized by the accumulation of numerous neurological symptoms and signs throughout its course. Fatigue is one of the most distressing complaints that MS patients may experience over their lifetime. In spite of its high prevalence, the pathophysiology of MS fatigue is far from being fully elucidated and a constellation of mechanisms seems implicated in this setting. Several factors could contribute to its development and/or exacerbation, and this requires a careful workup in order to search for all possible underlying causes, such as sleep disturbances, endocrine dysfunction and mood disorders, to cite a few...

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterised by multiple symptoms including fatigue, headaches and cognitive impairment, which have a significantly adverse effect on the normal functioning and well-being of the individual. These symptoms are often triggered or worsened following physical or mental exertion. ME/CFS has long been thought of as having a significant immunological component, but reports describing changes in immune function are often inconsistent between study groups...

The use of non-invasive brain neurostimulation (NIBS) techniques to treat neurological or psychiatric diseases is currently under development. Fatigue is a commonly observed symptom in the field of potentially treatable pathologies by NIBS, yet very little data has been published regarding its treatment. We conducted a review of the literature until the end of February 2017 to analyze all the studies that reported a clinical assessment of the effects of NIBS techniques on fatigue. We have limited our analysis to repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS)...

Cancer-related fatigue (CRF) is a commonly reported and debilitating side effect of cancer and/or cancer treatment. Sleep disorders are also highly reported in the cancer population; however it is unknown if sleep is associated with fatigue. In the general population, exercise has been shown to improve sleep, however in the cancer population this idea is under investigation. The primary purposes of this review were to: (i) review the prevalence and causes of sleep disorders in cancer patients and survivors, (ii) examine the relationship between sleep and CRF and (iii) review the impact of exercise interventions on sleep in cancer patients and survivors...

OBJECTIVES: While generic protocols exist for gait rehabilitation using robotic orthotics such as the Lokomat(®), several settings - guidance, body-weight support (BWS) and velocity - may be adjusted to individualize patient training. However, no systematic approach has yet emerged. Our objective was to assess the feasibility and effects of a systematic approach based on electromyography to determine subject-specific settings with application to the strengthening of the gluteus maximus muscle in post-stroke hemiparetic patients...

INTRODUCTION: We aimed to determine the effect of short day-time sleep on photoparoxysmal epileptic activity in sleep-deprived patients. METHODS: We retrospectively reviewed video-EEG recordings performed between 2003 and 2015. All recordings following at least four hours of sleep deprivation, including intermittent photic stimulation (IPS) both before and after sleep with any form of epileptiform activity were included. The study group was divided into four subgroups: (1) no photoparoxysmal response (PPR) group, with epileptiform activities other than PPRs; (2) increment group, with PPR duration increased by ≥200% after vs...

OBJECTIVE: Psychogenic nonepileptic seizures (PNES) are abrupt, paroxysmal changes in behavior or consciousness that may phenomenologically resemble epileptic seizures. Given the known association between anxiety and PNES, we hypothesized that in these subjects there may be evidence that the nervous system is hypersensitive to external stimuli. We aimed to test our hypothesis by means of the auditory startle reaction (ASR). By investigating ASR, we also had the opportunity to test presence of orienting reaction, which is generally defined as the second phase of response after the auditory stimulus, with longer latency...

OBJECTIVES: The technique of additional visual feedback has been shown to significantly decrease the center of pressure (CP) displacements of a standing subject. Body-weight asymmetry is known to increase postural instability due to difficulties in coordinating the reaction forces exerted under each foot and is often a cardinal feature of various neurological and traumatic diseases. To examine the possible interactions between additional visual feedback and body-weight asymmetry effects, healthy adults were recruited in a protocol with and without additional visual feedback, with different levels of body-weight asymmetry...

The chronic fatigue syndrome (CFS) remains a contentious and controversial presentation despite decades of systematic research from a variety of medical specialties and associated disciplines. Variously championed as a condition of immunological, neurological, neurophysiological, psychiatric or psychological origin, consensus on a cogent and evidenced-based pathway has yet to be achieved. Irrespective of the ambiguity regarding aetiology, what is incontrovertible is the experience of significant depression, which often accompanies this most distressing clinical presentation...

OBJECTIVES: Depression is one of the most prevalent mental illnesses and is associated with changes in emotion processing. The aim of this study was to determine the influence of depressive symptoms on EEG oscillatory dynamics accompanying implicit processing of angry and happy facial expressions in 46 healthy subjects. METHODS: The Beck Depression Inventory was used to assess the presence of depressive symptoms in normal subjects. During the experiment, they were told to categorize the gender of angry, neutral, or happy faces presented to them, while high-resolution EEG was recorded...

Fatigue is complex, representing simultaneously a physiological, psychological and social phenomenon. The sociological approach attempts to understand the experience of fatigue and its characterization at diverse periods and in various social contexts. After giving a sociological history of different forms of fatigue through the ages (acedia, melancholy, neurasthenia, chronic fatigue syndrome, etc.), this article proposes a social epidemiology of fatigue in the current period. Objectification of working and living conditions allows us to illustrate social inequalities in fatigue and exhaustion, but seems to contradict dominant social representations of fatigue today...

OBJECTIVE: To investigate the cause of transient weakness in myotonia congenita (MC) and the mechanism of action of mexiletine in reducing weakness. METHODS: The changes in neuromuscular excitability produced by 1min of maximal voluntary contractions (MVC) were measured on the amplitude of compound muscle action potentials (CMAP) in two patients with either recessive or dominant MC, compared to control values obtained in 20 healthy subjects. Measurements were performed again in MC patients after mexiletine therapy...

OBJECTIVES: Dorsolateral prefrontal cortex (DLPFC) is the main stimulation target for rTMS treatment of depression. DLPFC is located in the middle frontal gyrus and corresponds to the lateral part of Brodmann Areas 9 and 46. Current methods to locate the DLPFC are either based on head landmarks that are inaccurate, or based on MRI-neuronavigation. Neuronavigated-methods are based either on standardized stereotactic coordinates translated to the individual patient or on brain landmarks requiring neuroanatomical skills for their identification...

OBJECTIVE: To assess the efficacy of a combination of cognitive training (COG) and repetitive transcranial magnetic stimulation (rTMS), on cognitive performance, locomotor activity, apathy, caregiver burden and dependence of patients with Alzheimer's disease (AD). METHODS: A combination of COG and rTMS was performed in 10 patients with AD (NeuroAD procedure) for a period of 5weeks (one session per day, 5days a week), without maintenance sessions. Patients were evaluated at the end of the treatment (D45) and 6months later (M6) by the Mini Mental State Examination (MMSE), the Alzheimer disease assessment scale - cognitive subscale (ADAS-Cog), various neuropsychological tests and clinical scores specific for locomotor activity, apathy, caregiver burden, and dependence, recorded before the study (baseline)...

OBJECTIVES: To explore clinical-neurophysiological correlations in anti-myelin-associated glycoprotein (anti-MAG) neuropathy. METHODS: Clinical and electrophysiological data of 42 patients with anti-MAG neuropathy were retrospectively analysed. Disability was evaluated using the Overall Neuropathy Limitation Scale (ONLS), motor impairment through MRC sum score and sensory deficiency through INCAT sensory score. Compound motor action potential (CMAP) sum score was calculated adding the distal CMAP amplitude of the median, ulnar, tibial and fibular nerves of both sides...

In this technical note, a conveniently sized, single-channel somatosensory evoked potentials (SEP)-stimulation-recording unit for bedside use in the intensive care unit is presented. The validation of the SEP N20 wave in intensive care guidelines as initial parameter for the prognostic evaluation of cardiac arrest has increased the demand for a more widespread availability of SEP, outside the electrophysiological domain. A device with a simplified interface that safely guides the user through a complete examination and that includes artifact removal is a prerequisite for such more widespread use, in which expert interpretation can be reduced to a necessary minimum...
