Claudio L Bassetti, Panagiotis Bargiotas
Rapid eye movement sleep behavior disorder (RBD) is a brain disorder, characterized by the dream enactment during rapid eye movement (REM) sleep due to a lack of physiologic muscle atonia and increased muscle twitching. Schenk was the first to describe this disorder in 1986; however, few authors reported in the 1970-1980s loss of physiological muscle atonia combined with dream enactment in the course of brainstem disorders and as a consequence of alcoholism and antidepressant treatment. RBD affects less than 1% of the adult population, but can be found in up to 25-50% of neurodegenerative disorders including Parkinson's disease, multisystem atrophy, and dementia with Lewy body...

Children exposed to maternal smoking during pregnancy (MSDP) exhibit difficulties in executive function (EF) from infancy through adolescence. Due to the developmental significance of EF as a predictor of adaptive functioning throughout the life span, the MSDP-EF relation has clear public health implications. In this paper, we provide a comprehensive review of the literature on the relationship between MSDP and offspring EF across development; consider brain-based assessments, animal models, and genetically informed studies in an effort to elucidate plausible pathways of effects; discuss implications for prevention and intervention; and make calls to action for future research...

Exercise therapy is a promising nonpharmacological therapy in people with multiple sclerosis (MS). Although exercise training may induce a transient worsening of symptoms in some MS patients, it is generally considered safe and does not increase the risk of relapses. Exercise training can lead to clinically relevant improvements in physical function, but should be considered an adjunct to specific task-based training. Exercise has also shown positive effects on the brain, including improvements in brain volume and cognition...

BACKGROUND AND PURPOSE: Segmentation of human brain structures is crucial for the volumetric quantification of brain disease. Advances in algorithmic approaches have led to automated techniques that save time compared to interactive methods. Recently, the utility and accuracy of template library fusion algorithms, such as Local MAP PSTAPLE (PSTAPLE), have been demonstrated but there is little guidance regarding its reproducibility compared to single template-based algorithms such as FreeSurfer and FSL-FIRST...

Aim: Alzheimer's disease (AD) and other forms of dementia create a noncurable disease population in world's societies. To develop a blood-based biomarker is important so that the remedial or disease-altering therapeutic intervention for AD patients would be available at the early stage. Materials & methods: TDP-43 levels were analyzed in postmortem brain tissue and platelets of AD and control subjects. Results: We observed an increased TDP-43 (<60%) in postmortem AD brain regions and similar trends were also observed in patient's platelets...

Alzheimer's disease (AD) is an age-related neurodegenerative disorder of the brain. The presence of amyloid-beta (Aβ) plaques, neurofibrillary tangles (NFTs), loss of neurons, synapses, and altered sensory perceptions, including memory loss, delineate AD. However, the cause of AD is not clearly known. Several genetic and nongenetic factors have been implicated in the disease. Of the genes, the ɛ4 allele of apolipoprotein E is the largest known genetic risk factor of AD. This review article focuses on the various genetic and other predisposing factors that account for AD, pathophysiology of the disease, and the mechanisms by which Aβ plaques and NFTs are formed and could affect AD brain...

Confabulation, or the unintentional production of false, distorted or displaced memories, is commonly seen in people who have brain injury. However, it is most common in the acute phase, with persistent confabulation being comparatively rare. In this paper, we describe the case of Joe, a 24-year-old man who showed confabulation in the chronic phase of his rehabilitation, three years after traumatic brain injury. We describe our approach to therapy for this confabulation, and in particular how collaborative formulation enabled Joe to understand his confabulation, and then to manage it effectively, using a diary and "detective" procedure to identify whether or not evidence existed to support potentially confabulated memories...

The main objective of "Lifebrain" is to identify the determinants of brain, cognitive and mental (BCM) health at different stages of life. By integrating, harmonising and enriching major European neuroimaging studies across the life span, we will merge fine-grained BCM health measures of more than 5,000 individuals. Longitudinal brain imaging, genetic and health data are available for a major part, as well as cognitive and mental health measures for the broader cohorts, exceeding 27,000 examinations in total...

Heavy episodic drinking, also termed binge drinking, is commonly practiced by young adults. It is accompanied by a range of cognitive, affective, and social problems, but the neural dynamics underlying changes in emotional functions is poorly understood. To investigate the behavioral and brain indices of affective processing as a function of binge drinking, young, healthy participants (23.3 ± 3.3 years) were assigned to two groups (n = 32 each) based on their drinking habits. Binge drinking (BD) participants reported drinking heavily with at least five binge episodes in the last 6 months, whereas light drinkers (LD) reported no more than one binge episode in the last 6 months...

BACKGROUND: Patients presenting with an early GCS score of 3-5 after blunt or penetrating skull-brain assaults are categorized as having sustained a very severe Traumatic Brain Injury (vs-TBI). This category is often overlooked in literature. Impact on patients and families lives however is huge and the question "whether to surgically treat or not" frequently poses a dilemma to treating physicians. Little is known about mortality and outcome, compared to what is known for the group of severe TBI patients (s-TBI) (GCS 3- 8)...

Patients with multiple sclerosis (MS) are often nonadherent to their disease modifying therapy (DMT). While recent studies demonstrate enhanced DMT adherence following intervention grounded in motivational interviewing (MI), little is known about how to address DMT reinitiation among MS patients who have prematurely discontinued DMT against medical advice and do not intend to reinitiate. We examined baseline predictors of DMT reinitiation among patients with MS who discontinued medications against medical advice following a telephone-based MI and Cognitive Behavioral Therapy (MI-CBT) intervention...

Introduction: Inconsistent results from previous studies of exercise and cognitive function suggest that rigorously designed randomized controlled trials are urgently needed. Here, we describe the design of the Intense Physical Activity and Cognition (IPAC) study, which will assess the impact of a 6-month high-intensity exercise intervention on cognitive function and biomarkers of dementia risk, compared with a 6-month moderate-intensity exercise intervention and control group (no study-related exercise)...

Depression is a syndrome of stress- and emotion-dysregulation, involving compromised structural integrity of frontal-limbic networks. Meta-analytic evidence indicates that volumetric reductions in the hippocampus, anterior cingulate cortex, prefrontal cortex, striatum, and amygdala, as well as compromised white matter integrity are frequently observed in depressed adults. Exercise has shown promise as an effective treatment for depression, but few studies have attempted to characterize or identify the neural mechanisms of these effects...

BACKGROUND: Brain-Computer Interface (BCI) is a set of technologies that are of increasing interest to researchers. BCI has been proposed as assistive technology for individuals who are non-communicative or paralyzed, such as those with amyotrophic lateral sclerosis or spinal cord injury. The technology has also been suggested for enhancement and entertainment uses, and there are companies currently marketing BCI devices for those purposes (e.g., gaming) as well as health-related purposes (e...

Many smokers attempt to quit every year, but 90% relapse within 12 months. Converging evidence suggests relapse is associated with insufficient activation of the prefrontal cortex. Delay discounting rate reflects relative activity in brain regions associated with relapse. High-frequency repetitive transcranial magnetic stimulation (rTMS) of the left dorsolateral prefrontal cortex (LDLPFC) increases cortical excitability and reduces delay discounting rates, but little is known about feasibility, tolerability, and potential efficacy for smoking cessation...

Cognitive impairment is one of the most important clinical features of neurodegenerative disorders including multiple sclerosis (MS). Conducted research shows that up to 65 percent of MS patients have cognitive deficits such as episodic memory, sustained attention, reduced verbal fluency; however, the cognitive MS domain is information processing speed. It is the first syndrome of cognitive dysfunction and the most widely affected in MS. Occasionally these impairments occur even before the appearance of physical symptoms...

Neurorehabilitation training is a therapeutic intervention for the loss of neural function induced by focal cerebral ischemia, however, the effect varies depending on the neurorehabilitation exercises. Willed movement (WM) training is defined as task‑oriented training, which increases enthusiasm of patients to accomplish a specific task. The current study was performed to the evaluate effect of WM training on neurorehabilitation following focal cerebral ischemia, and further investigate the influence on neural plasticity‑associated signaling pathway...
