Researchers Identify New Type of Vertigo, According to Study Published in ‘Neurology’
With vertigo, people have episodes of dizziness that can last from minutes to days. Vertigo can be caused by serious conditions, such as tumors, or conditions that are fairly benign, such the inner ear disorder Meniere’s disease. But for some people, no cause can be found.
In this new study, neurologists have identified a new type of vertigo where treatment may be effective.
“These conditions can be difficult to diagnose and quite debilitating for people, so it’s exciting to be able to discover this new diagnosis of a condition that may respond to treatment,” said study author Ji-Soo Kim, MD, PhD, of Seoul National University in Seongnam, South Korea.
To diagnose this new condition, the person sits in a dark room and the examiner moves the patient’s head forward and then the head is shaken horizontally for about 15 seconds. Then the patient opens his or her eyes and a video recording is taken of eye movements. The neurologists discovered that after the test, people with this new condition had eye movements called nystagmus that lasted longer than for other people. The new condition is called recurrent spontaneous vertigo with head-shaking nystagmus.
Among 338 people with vertigo with no known cause, 35 had this new condition and were included in the study. The participants had attacks of vertigo ranging from two or three times a week to once a year. They also experienced nausea or vomiting, headaches, and intolerance of head motions during the attacks.
The participants were compared to 35 people with other conditions that can cause vertigo, such Meniere’s disease, vestibular migraine, and vestibular neuritis. The test measured the time constant, or the time that represents the speed with which the reflexive eye movements can respond to change. For those with the new condition, the time constant during the primary phase of the nystagmus was 12 seconds, while it was six seconds for those with Meniere’s disease and five seconds for those with vestibular neuritis and vestibular migraine.
The neurologists also found that people with the new type of vertigo were more likely to have severe motion sickness than those with other types of vertigo.
A total of 20 of the 35 people with the new type of vertigo who had frequent attacks and severe symptoms were given preventive medication. About one-third of those had partial or complete recovery with the new medication. During the long-term follow-up of an average of 12 years after the first symptoms for 31 participants, five reported no more attacks, 14 said their symptoms had improved, and only one said symptoms had gotten worse.
Kim said that people with this condition may have a hyperactive mechanism in their vestibular system that helps the brain respond to movement of the body and in the environment.
“It’s possible that the vertigo occurs when this unstable mechanism is disrupted by factors either within the person’s body or in their environment,” Kim said.

New Hearing Devices in Development May Expand Range of Human Hearing
Researchers at Case Western Reserve University are developing atomically thin ‘drumheads’ able to receive and transmit signals across a radio frequency range far greater than what we can hear with the human ear, the University announced in a press release.
But the drumhead is tens of trillions times (10 followed by 13 zeros) smaller in volume and 100,000 times thinner than the human eardrum.
It’s been said that the advances will likely contribute to making the next generation of ultralow-power communications and sensory devices smaller and with greater detection and tuning ranges.
“Sensing and communication are key to a connected world,” said Philip Feng, an associate professor of electrical engineering and computer science and corresponding author on a paper about the work published March 30 in the journal Science Advances. “In recent decades, we have been connected with highly miniaturized devices and systems, and we have been pursuing ever-shrinking sizes for those devices.”
The challenge with miniaturization: Also achieving a broader dynamic range of detection, for small signals, such as sound, vibration, and radio waves.
“In the end, we need transducers that can handle signals without losing or compromising information at both the ‘signal ceiling’ (the highest level of an undistorted signal) and the ‘noise floor’ (the lowest detectable level),” Feng said.
While this work was not geared toward specific devices currently on the market, researchers said, it was focused on measurements, limits, and scaling which would be important for essentially all transducers.
Those transducers may be developed over the next decade, but for now, Feng and his team have already demonstrated the capability of their key components—the atomic layer drumheads or resonators—at the smallest scale yet.
The work represents the highest reported dynamic range for vibrating transducers of their type. To date, that range had only been attained by much larger transducers operating at much lower frequencies—like the human eardrum, for example.
“What we’ve done here is to show that some ultimately miniaturized, atomically thin electromechanical drumhead resonators can offer remarkably broad dynamic range, up to ~110dB, at radio frequencies (RF) up to over 120MHz,” Feng said. “These dynamic ranges at RF are comparable to the broad dynamic range of human hearing capability in the audio bands.”
New dynamic standard
Feng said the key to all sensory systems, from naturally occurring sensory functions in animals to sophisticated devices in engineering, is that desired dynamic range.
Dynamic range is the ratio between the signal ceiling over the noise floor and is usually measured in decibels (dB).
Human eardrums normally have dynamic range of about 60 to 100dB in the range of 10Hz to 10kHz, and our hearing quickly decreases outside this frequency range. Other animals, such as the common house cat or beluga whale, can have comparable or even wider dynamic ranges in higher frequency bands.
The vibrating nanoscale drumheads developed by Feng and his team are made of atomic layers of semiconductor crystals (single-, bi-, tri-, and four-layer MoS2 flakes, with thickness of 0.7, 1.4, 2.1, and 2.8 nanometers), with diameters only about 1 micron.
They construct them by exfoliating individual atomic layers from the bulk semiconductor crystal and using a combination of nanofabrication and micromanipulation techniques to suspend the atomic layers over microcavities predefined on a silicon wafer, and then making electrical contacts to the devices.
Further, these atomically thin RF resonators being tested at Case Western Reserve show excellent frequency ‘tunability,’ meaning their tones can be manipulated by stretching the drumhead membranes using electrostatic forces, similar to the sound tuning in much larger musical instruments in an orchestra, Feng said.
The study also reveals that these incredibly small drumheads only need picoWatt (pW, 10^-12 Watt) up to nanoWatt (nW, 10^-9 Watt) level of RF power to sustain their high frequency oscillations.
“Not only having surprisingly large dynamic range with such tiny volume and mass, they are also energy-efficient and very ‘quiet’ devices,” Feng said. “We ‘listen’ to them very carefully and ‘talk’ to them very gently.”

City, University of London to Pilot Language and Reading Intervention for Children
Researchers from City, University of London have been awarded £97k ($USD approximately $136,479) from the Nuffield Foundation to pilot a language and reading intervention with 120 children in their first year of formal education, the school announced on its website.
Involving Dr Ros Herman, Professor Penny Roy, and Dr Fiona Kyle from the School of Health Science’s Division of Language and Communication Science, in collaboration with Professor Charles Hulme from Oxford University, the study—which is reportedly the first reading intervention study to include both deaf and hearing children—will trial the new intervention in primary schools for a year and compare outcomes with other schools that offer the standard literacy teaching.
The research team have shown in previous research that many severely and profoundly deaf children have significant reading delays, yet are typically excluded from reading intervention research.
In this new study, teachers will be trained to deliver the intervention program, comprising systematic phonics teaching alongside a structured vocabulary program, during the school literacy hour. The study will investigate whether all children, or only specific groups of children, benefit from the integrated program and whether a full-scale evaluation is merited.
Dr Herman said, “Our previous research has revealed the scale of reading difficulties among deaf children. Our findings suggest that deaf children will benefit from specialist literacy interventions such as those currently offered to hearing children with dyslexia. In addition, deaf children and many hearing children require ongoing support to develop the language skills that underlie literacy.
“As a result we hope our new study, which will pilot a combined language and reading intervention, will address these issues so that teachers can provide the vital support needed to prevent both hearing and deaf children from unnecessarily falling behind their peers.”

GN Store Nord Develops Device to Protect Soldiers’ Hearing
The global market for military communication systems is estimated to be about $630 million, and features competitors such as Peltor (3M), INVISIO, Silynx, Racal Acoustics, and MSA Sordin, according to long-time hearing industry analyst Niels Granholm-Leth of Carnegie Investment Bank in Copenhagen. GN has embarked on several projects in its GN Stratcom organization, which is currently part of GN Hearing, although the company could eventually establish it as a stand-alone division alongside its Hearing (ReSound, Beltone, and Interton) and Headset divisions (Jabra).
The new patented hearing protection solution is designed specifically for defense and security forces. GN says the solution offers the user a communication headset which is designed to be comfortable, highly durable, and protects the user against high volume noise. At the same time, by leveraging GN’s expertise within situational awareness, the solution allows its user to clearly identify important sound in 360°.
“The GN Group encompasses consumer, professional, and medical grade hearing technology under the same roof,” says CEO of GN Hearing, Anders Hedegaard. “This unique platform makes it possible to expand GN’s business into adjacent opportunities within the sound space. With our user-centric approach we aim to be the leader in intelligent audio solutions to transform lives through the power of sound.”
GN will be starting to build a small, swift group related to this new business opportunity. This year, GN will participate in military tenders in the United States and with other NATO-countries. The new product line will, under the name GN FalCom, include:
- Comfort. Designed for optimal physical comfort allowing for multiple hours of use in extreme combat situations;
- Clarity. Enables users to localize sounds all around them without the need to remove the earpiece. To maintain high quality communications at all times, GN FalCom will integrate seamlessly with military radio technology, and
- Protection. Allows users to stay connected while benefitting from noise protection. For example, users will experience the highest level of safety without blocking out wanted sounds.
The hearing protection solution builds on GN’s expertise in sound processing from both GN Hearing and GN Audio—and across R&D teams in the United States and Denmark. It is a successful result of corporate level investments made through GN’s Strategy Committee guided initiatives to explore opportunities outside of, but related to, GN’s existing business areas. According to the company, the hearing protection solution will be manufactured at GN’s existing production facilities in Bloomington, Minn, and will not impact GN’s financial guidance for 2018.
