Idiopathic intracranial hypertension (IIH) is a neurological disorder involving too much cerebrospinal fluid pressure, resulting in severe headaches, swelling of the optic nerves, vision loss, double vision, and a whooshing noise in the ears. The disease affects about one in 5,000 people, and is more common in women.
Researchers reviewed the medical records of 721 people with this kind of intracranial hypertension. Only nine percent of the group was male. Participants underwent eyesight exams and brain scans.
The study found that men with intracranial hypertension were two times more likely to experience severe vision problems in one or both eyes. Severe vision loss was defined as meeting the criteria for legal blindness.
“While IIH occurs less often in men, their increased frequency of severe vision loss compared to women is a major concern,” said lead study author Beau Bruce, MD, of Emory University in Atlanta and member of the American Academy of Neurology. “Our findings suggest that men with this condition should have more careful monitoring of their eyesight and likely should be treated more aggressively when they do have evidence of vision loss.”
The study also found men were more likely to have diagnosed sleep apnea. Bruce says that more prospective studies are needed to evaluate the role of sleep apnea in the treatment of people with intracranial hypertension, but that doctors should consider referring all appropriate people, both men and women with IIH, for sleep studies.
The study was supported by a grant from Research to Prevent Blindness, Inc. and by the National Institutes of Health.
The American Academy of Neurology, an association of more than 21,000 neurologists and neuroscience professionals, is dedicated to improving patient care through education and research. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as stroke, Alzheimer’s disease, epilepsy, Parkinson’s disease, and multiple sclerosis.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
