Modafinil for the Improvement of Patient Outcomes Following Traumatic Brain Injury
Conclusion. Modafinil is a central nervous system stimulant with well-established effectiveness in the treatment of narcolepsy and shift-work sleep disorder. There is conflicting evidence about the benefits of modafinil in the treatment of fatigue and EDS secondary to TBI. One randomized, controlled study states that modafinil does not significantly improve patient wakefulness, while another concludes that modafinil corrects EDS but not fatigue. An observational study provides evidence that modafinil increases alertness in fatigued patients with past medical history of brainstem diencephalic stroke or multiple sclerosis. ...

Role of repetitive transcranial magnetic stimulation in stroke rehabilitation.
Authors: Pinter MM, Brainin M Abstract In recent years, efforts have focused on investigating the neurophysiological changes that occur in the brain after stroke, and on developing novel strategies such as additional brain stimulation to enhance sensorimotor and cognitive recovery. In the 1990s, repetitive transcranial magnetic stimulation (rTMS) was introduced as a therapeutic tool for improving the efficacy of rehabilitation for recovery after stroke. It is evident that disturbances of interhemispheric processes after stroke result in a pathological hyperactivity of the intact hemisphere. The rationale of using r...

A Case of Transient Global Amnesia: A Review and How It May Shed Further Insight into the Neurobiology of Delusions
Conclusion In closing, our patient’s episode of TGA combined with her emotional and perceptual response lends credence to the proposal of a “fear/paranoia” circuit in the genesis of paranoid delusions—a circuit incorporating amygdala, frontal, and parietal cortices. Here, neutral or irrelevant stimuli, thoughts, and percepts come to engender fear and anxiety, while dysfunction in frontoparietal circuitry engenders inappropriate social predictions and maladaptive inferences about the intentions of others.[54] Hippocampus relays information about contextual information based on past experiences and the current situat...

Probable Nootropic-induced Psychiatric Adverse Effects: A Series of Four Cases
Conclusion Healthcare providers in general, and specifically those in the mental health and substance abuse fields, should keep in mind that nootropic use is an under recognized and evolving problem. Nootropic use should be considered in cases where there are sudden or unexplained exacerbations of psychiatric symptoms in patients who have been stable and medication adherent. It is also important to remember that most nootropics are not detected on standard drug toxicology screening tests. We have very little clinical information on how nootropics may interact with psychotropics (or other medications) and potentially cause ...

Autism in the Son of a Woman with Mitochondrial Myopathy and Dysautonomia: A Case Report
Conclusion Given emerging evidence that mitochondrial dysfunction, particularly in the electron transport chain needed for cellular energy production, is an underlying pathophysiological mechanism for some varieties of ASD, clinicians should have a high index of suspicion for mitochondrial disease, especially when they encounter a patient with unusual neurological or constitutional symptoms. The prevalence of mitochondrial disease in ASD patients may be as high as five percent, which means that it is not the “zebra”[27] diagnosis that it might be in a non-ASD patient, where prevalence is about 0.01 percent.10 Reference...

Effects of unilateral stereotactic posterior striatotomy on harmaline‐induced tremor in rats
Although long known and the most prevalent movement disorder, pathophysiology of essential tremor (ET) remains controversial. The most accepted hypothesis is that it is caused by a dysfunction of the olivocerebellar system. Vilela Filho et al. [2001; Stereotact Funct Neurosurg 77:149–150], however, reported a patient with unilateral hand ET that was completely relieved after a stroke restricted to the contralateral posterior putamen and suggested that ET could be the clinical manifestation of posterior putamen hyperactivity. The present study was designed to evaluate this hypothesis in the most often used model of ET, ha...

Resting-state sensorimotor rhythm (SMR) power predicts the ability to up-regulate SMR in an EEG-instrumental conditioning paradigm
During instrumental conditioning of EEG activity (EEG-IC), participants receive feedback of a specific aspect of their brain signals (Lubar et al., 1995), e.g. feedback on the power of a certain frequency band. Desired patterns of EEG activity are rewarded by visual or auditory stimuli, thus enabling participants to modulate their brain activity by means of instrumental conditioning. EEG-IC training has been used to treat patients with disorders such as epilepsy (Sterman and Egner, 2006), attention deficit hyperactivity disorder (Arns et al., 2009) and stroke (Doppelmayr et al., 2007), as well as in healthy participants (H...

Assessment of potential cardiovascular risks of methylphenidate in comparison with sibutramine: do we need a SCOUT (trial)?
Abstract With the recent approval of methylphenidate (MPH) for treating attention-deficit/hyperactivity disorder (ADHD) in adults, the number of patients exposed will increase tremendously. The ongoing debate on the cardiovascular safety of MPH has triggered two large retrospective cohort studies in children and adolescents as well as in young to middle-aged adults. These studies looked into serious cardiovascular events (sudden cardiac death, acute myocardial infarction and stroke) as primary endpoints and concluded that MPH was safe after a mean duration of 2.1 years of follow-up in children and adolescent...

Rhynchophylline Protects Against the Amyloid β-Induced Increase of Spontaneous Discharges in the Hippocampal CA1 Region of Rats.
Abstract Accumulated soluble amyloid β (Aβ)-induced aberrant neuronal network activity has been recognized as a key causative factor leading to cognitive deficits which are the most outstanding characteristic of Alzheimer's disease (AD). As an important structure associated with learning and memory, the hippocampus is one of the brain regions that are impaired very early in AD, and the hippocampal CA1 region is selectively vulnerable to soluble Aβ oligomers. Our recent study showed that soluble Aβ1-42 oligomers induced hyperactivity and perturbed the firing patterns in hippocampal neurons. Rhynchophylline (RIN...

Electroencephalographic neurofeedback: Level of evidence in mental and brain disorders and suggestions for good clinical practice
Publication date: Available online 6 November 2015 Source:Neurophysiologie Clinique/Clinical Neurophysiology Author(s): J.-A. Micoulaud-Franchi, A. McGonigal, R. Lopez, C. Daudet, I. Kotwas, F. Bartolomei The technique of electroencephalographic neurofeedback (EEG NF) emerged in the 1970s and is a technique that measures a subject's EEG signal, processes it in real time, extracts a parameter of interest and presents this information in visual or auditory form. The goal is to effectuate a behavioural modification by modulating brain activity. The EEG NF opens new therapeutic possibilities in the fields of psychiat...

Transcranial Magnetic and Direct Current Stimulation in Children
AbstractPromising results in adult neurologic and psychiatric disorders are driving active research into transcranial brain stimulation techniques, particularly transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), in childhood and adolescent syndromes. TMS has realistic utility as an experimental tool tested in a range of pediatric neuropathologies such as perinatal stroke, depression, Tourette syndrome, and autism spectrum disorder (ASD). tDCS has also been tested as a treatment for a number of pediatric neurologic conditions, including ASD, attention-deficit/hyperactivity disorder, ...

Neuroscience is the Next Oncology
by Michael D. Ehlers, MD, PhD Dr. Ehlers is with Biogen in Cambridge, Massachusetts. Innov Clin Neurosci. 2018;15(3–4):15–16 Funding: No funding was received for the preparation of this article. Disclosures: Dr. Ehlers is an employee and shareholder at Biogen Inc. in Cambridge, Massachusetts. Prominent and expensive failures in Alzheimer’s disease therapies have led to a contagious belief system in some parts of the biopharma industry that neuroscience is just too hard, too risky, and too uncertain. But, might this belief system itself be a residual bias of the past? Close inspection reveals all the signs of a coming...
