How Long You Sleep May Be In Your Genes
This study is one of the first to begin identifying these genetic differences, and will hopefully help us better understand the causes of sleep disorders and their relation to other important conditions, such as diabetes and psychiatric disorders." [5 Things You Must Know About Sleep] Previous research has linked both sleeping too much and sleeping too little with health problems such as obesity, diabetes, hypertension, heart disease, psychiatric illness and even premature mortality, according to the study. For example, in a 2013 study published in the journal PLOS ONE, researchers found that the risk of type 2 diabetes wa...

Out of the Frying Pan, Into the Fire: A Case of Heat Shock and Its Fatal Complications
Abstract: Exertional heat stroke incidence is on the rise and has become the third leading cause of death in high school athletes. It is entirely preventable, yet this is a case of a 15-year-old, 97-kg male football player who presented unresponsive and hyperthermic after an August football practice. His blood pressure was 80/30, and his pulse was 180. He had a rectal temperature of 107.3°F, and upon entering the emergency department, he was rapidly cooled in 40 minutes. As he progressed, he developed metabolic acidosis, elevated liver enzymes, a prolapsed mitral valve with elevated troponin levels, and worsening hypotens...

Neurofeedback: How Is It Used for Treatment?
How does neurofeedback treat symptoms such as anxiety, sleeping problems, headaches, memory problems and ADHD? Read how Neurofeedback treats these symptoms, along with causes relating to dysregulation of the brainwaves and/or neural hubs as seen in a concussion, stroke, MS, autism, and parkinson disease. Neurofeedback can also be used to improve brain function!read more

Assessment of potential cardiovascular risks of methylphenidate in comparison with sibutramine: do we need a SCOUT (trial)?
Authors: Antel J, Albayrak O, Heusch G, Banaschewski T, Hebebrand J 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 ...

The spontaneously hypertensive rat/Izm (SHR/Izm) shows attention deficit/hyperactivity disorder-like behaviors but without impulsive behavior: Therapeutic implications of low-dose methylphenidate.
In this study, ADHD-like behaviors in SHR/Izm were evaluated compared to Wistar rats. SHR/Izm showed high locomotor activity in the habituation phase in a novel environment, although locomotor activity in the initial exploratory phase was low. In a behavioral test for attention, spontaneous alternation behavior in the Y-maze test was impaired in SHR/Izm. However, impulsive behavior in the elevated-plus maze test, which is designed to detect anxiety-related behavior but also reflects impulsivity for novelty seeking, was comparable to Wistar rats. Hyperactivity and inattention, detected as ADHD-like behaviors in SHR/Izm, wer...

The Applications of Pharmacogenomics to Neurological Disorders.
Abstract The most common neurological disorders, including neurodegenerative diseases and psychiatric disorders, have received recent attention with regards to pharmacogenomics and personalized medicine. Here, we will focus on a neglected neurodegenerative disorder, cerebral ischemic stroke (CIS), and highlight recent advances in two disorders, Parkinson's disease (PD) and Alzheimer's diseases (AD), that possess both similar and distinct mechanisms in regards to therapeutic targets. Current attempts to link symptoms from other disorders to candidate genes have been effective in identifying candidate genes for stro...

Intravenous methylphenidate: an unusual way to provoke ST-elevation myocardial infarction
Acute ST-T elevation is a sign of myocardial ischemia or infarction usually due to coronary artery atherosclerosis or coronary spasm. Coronary spasm may be spontaneous or can occur as a result of a drug that causes arterial spam. Ritalin, Novartis Pharmaceut. Corporation, USA (methylphenidate hydrochloride), a dopamine reuptake inhibitor, is an oral drug used to treat attention-deficit/hyperactivity disorder and narcolepsy. Sudden deaths, stroke, and myocardial infarction have been reported in adults taking stimulant drugs at usual dose for attention-deficit/hyperactivity disorder [1].

Myocardial injury in a 41-year-old male treated with methylphenidate: a case report
Conclusions: When interpreting troponin results it is important to take into account the context of the patient's clinical presentation, including the possibility of adverse drug reactions. The adverse drug reaction could include a combination of vasospasm and/or increased oxygen demand due to tachycardia. This case should be borne in mind before a diagnosis of myocardial infarction is given, or a decision to perform invasive coronary angiography is made in patients that use methylphenidate or related substances. Cardiac magnetic resonance imaging could be of diagnostic value in such cases.

Joint hypermobility and autonomic hyperactivity: relevance to neurodevelopmental disorders
Conclusion We demonstrate for the first time that rates of hypermobility and symptoms of autonomic dysfunction are particularly high in adults with neurodevelopmental diagnoses. It is likely that the importance of hypermobility and autonomic dysfunction to the generation and maintenance of psychopathology in neurodevelopmental disorders is poorly appreciated. Work underway(autonomic testing, fMRI) will test the hypothesis that autonomic reactivity and interoceptive sensitivity predispose to the expression of psychiatric symptoms, particularly anxiety. It is further hypothesized that inefficient neural co-ordination of effe...

The use of stimulant medications for non-core aspects of ADHD and in other disorders.
Abstract Psychostimulants play a central role in the management of ADHD. Here we review the evidence pertaining to the use of methylphenidate, dexamphetamine and related amphetamine salts, the prodrug lisdexamfetamine and modafinil for the management of comorbid ADHD and non-ADHD indications. There is a growing consensus that stimulant medications are helpful at improving the emotional dysregulation and lability, and oppositional and conduct symptoms that are often associated with ADHD. There is some evidence that psychostimulants may improve outcomes in those with treatment resistant depression, reduce negative s...

Adult onset methylphenidate induced dyskinesia after stroke
Methylphenidate is a stimulant medication that is commonly used to treat attention-deficit/hyperactivity disorder (ADHD). It is also used as adjuvant therapy for improving disability after stroke. Recently, Moreau et al. reported that methylphenidate improved gait hypokinesia and freezing in patients with advanced Parkinson's disease (PD) . The most common side effects of methylphenidate are; insomnia, anorexia, weight loss, abdominal pain, headache, irritability, anxiety, tachycardia, hypertension, and motor tics. Dyskinesia as a side effect of methylphenidate is rare, and only a few cases have been reported . Most of th...

Aberrant CaMKII activity in the medial prefrontal cortex is associated with cognitive dysfunction in ADHD model rats.
Abstract Attention-deficit/hyperactivity disorder (ADHD) is a heterogeneous neurobehavioral disorder accompanied by cognitive and learning deficits, which is prevalent among boys. Juvenile male stroke-prone spontaneously hypertensive rats (SHRSP) exhibit ADHD-like behaviors including cognitive deficits and represent one animal model of ADHD. Here, we define a mechanism underlying cognitive dysfunction observed in SHRSP. Acute methylphenidate (MPH: 1mg/kg, p.o.) administration to SHRSP significantly improved not only inattention in a Y-maze task but also cognitive dysfunction in a novel object recognition test. Int...
