Anti-NMDA receptor encephalitis - Wikipedia. Anti-NMDA receptor encephalitis, also known as NMDA receptor antibody encephalitis, is an acute form of encephalitis that is potentially lethal but has a high probability for recovery with treatment.
It is caused by an autoimmune reaction, primarily against the NR1 subunit of the NMDA receptor (N-methyl D-aspartate receptor). The condition is associated with tumours, mostly teratomas of the ovaries, and thus can be considered a paraneoplastic syndrome. However, there are a substantial number of cases with no detectable tumour, and in fact it appears that most patients do not have a tumour. The disease was officially categorized and named by Josep Dalmau and colleagues in 2007. High Levels of Glutamate in Brain May Kick-Start Schizophrenia. NEW YORK — An excess of the brain neurotransmitter glutamate may cause a transition to psychosis in people who are at risk for schizophrenia, reports a study from investigators at Columbia University Medical Center (CUMC) published in the current issue of Neuron.
The findings suggest 1) a potential diagnostic tool for identifying those at risk for schizophrenia and 2) a possible glutamate-limiting treatment strategy to prevent or slow progression of schizophrenia and related psychotic disorders. “Previous studies of schizophrenia have shown that hypermetabolism and atrophy of the hippocampus are among the most prominent changes in the patient’s brain,” said senior author Scott Small, MD, Boris and Rose Katz Professor of Neurology at CUMC. “The most recent findings had suggested that these changes occur very early in the disease, which may point to a brain process that could be detected even before the disease begins.” ATSDR - Environmental Medicine & Environmental Health Education - CSEM. Acetylcholinesterase/paraoxonase genotype and expression predict anxiety scores in Health, Risk Factors, Exercise Training, and Genetics study.
Cholinergic crisis - Wikipedia. A cholinergic crisis is an over-stimulation at a neuromuscular junction due to an excess of acetylcholine (ACh), as of a result of the inactivity (perhaps even inhibition) of the AChE enzyme, which normally breaks down acetylcholine.
This is a consequence of some types of nerve gas, (e.g. sarin gas). In medicine, this is seen in patients with myasthenia gravis who take too high a dose of their cholinesterase inhibitor medications, or seen following general anaesthesia, when too high a dose of a cholinesterase inhibitor drug is given to reverse surgical muscle paralysis.

Syrian chemical attack used sarin and was worst in 25 years, says UN. The Guardian. September 17, 2013. Personal web site of Prof. Hermona Soreq. Our research is centered on acetylcholine functioning; with a focus on molecular biology and genomic applications to the study of cholinergic signaling, and especially on its microRNA regulation.
Our work spans both basic and biomedical studies on cholinergic signaling in health and disease, particularly on anxiety-related topics. MicroRNAs (miRNAs) rapidly emerge as global regulators of gene expression, yet the full scope of their roles in brain functioning is largely unknown. We combine advanced sequencing technologies with computational and transgenic engineering tools to investigate miRNA functions in the healthy and diseased brain, in particular acetylcholine-related processes. A blood test to detect anxiety. According to IsraCast, a team of Israeli scientists has discovered a very innovative way to detect people suffering from anxiety disorders but who appear to be healthy.
A simple blood test will reveal if you're unable to handle stress and if you need a medical treatment without the need for any psychological advise. Such a simple test would be particularly helpful for soldiers returning from war zones or for people having being subjected to severe stress, such as after terrorist attacks or natural disasters. This blood test should be available next year. But the researchers are already working on another diagnosis tool, this one for depression.
This blood test is based on research done by Hermona Soreq and her colleagues at the Alexander Silberman Institute of Life Sciences of the Hebrew University of Jerusalem, Israel. Organophosphates Profile – Urine. The Organophosphates Profile is a urine test that identifies a patient's prolonged exposed to organophosphate pesticides.
The Organophosphates Profile uncovers exposure to these pesticides, insecticides, and herbicides to determine if avoidance and detoxification are needed for optimal health. Organophosphate pesticides/insecticides are nerve agents that inactivate an important enzyme which is essential to nerve function. This can cause neurodevelopment disorders in small children and fetuses.
Photosensitive epilepsy - Wikipedia. Photosensitive epilepsy (PSE) is a form of epilepsy in which seizures are triggered by visual stimuli that form patterns in time or space, such as flashing lights, bold, regular patterns, or regular moving patterns.
Signs and symptoms People with PSE experience epileptiform seizures upon exposure to certain visual stimuli. Flicker vertigo - Wikipedia. This phenomenon has been observed during helicopter flight; a Dr.
Bucha identified the phenomenon in the 1950s when called upon to investigate a series of similar and unexplained helicopter crashes. Flicker vertigo in a helicopter occurs when the pilot or front passenger looks up through the blades of the main rotor as it turns in the sun causing the light to strobe. Flicker (screen) - Wikipedia. Flicker is a visible fading[clarification needed] between cycles displayed on video displays, especially the refresh interval on cathode ray tube (CRT) as well as Plasma based computer screens and/or TVs.
Flicker occurs on CRTs when they are driven at a low refresh rate, allowing the brightness to drop for time intervals sufficiently long to be noticed by a human eye – see persistence of vision and flicker fusion threshold. For most devices, the screen's phosphors quickly lose their excitation between sweeps of the electron gun, and the afterglow is unable to fill such gaps – see phosphor persistence. Irlen syndrome - Wikipedia. Irlen syndrome, occasionally referred to as scotopic sensitivity syndrome (SSS) or Meares-Irlen syndrome, very rarely as asfedia, and recently also as visual stress, is a proposed disorder of vision. It is not recognised by any scientific or medical body. History In 1980 New Zealand teacher Olive Meares described the visual distortions some individuals reported when reading from white paper.
