Peripheral vestibular dysfunction can be caused by inner ear disorders, drug toxicity, neuritis, or a number of other causes. In the absence of a fully functional vestibular system, the brain often requires retraining to correctly utilize visual and proprioceptive cues to maintain postural stability.
People with vestibular dysfunction experience multiple problems with posture control and movement, including an unsteady gait and various balance-related difficulties. These effects make it very difficult to walk in the dark or on uneven surfaces without risk of falling. They are typically referred for conventional vestibular therapy. Many patients improve with therapeutic intervention. Some patients reach a plateau and do not return to their previous level of function. The BrainPort balance device transmits head position information via electrotactile stimulation of the tongue. With training, patients learn to use the positional information to correct their balance.
Nearly half of adolescents and young adults with lingering symptoms of concussion suffer from an eye coordination disorder that causes blurred and double vision, headaches and difficulties concentrating. There is no proven method for treating the condition when it occurs after a head injury.
Researchers at the University of Manchester, UK, aimed to systematically review the literature to provide evidence on SARS-CoV-2 and audio-vestibular symptoms. They found that COVID-19 has been tied to hearing loss, vertigo, and tinnitus.
Researchers at the Stanford University School of Medicine have found a way to regenerate hair cells in the inner ears of mice, allowing the animals to recover vestibular function. It's the first time such recovery has been observed in mature mammals.
The U.S. Department of Veterans Affairs should expand the requirement in its disability compensation process regarding who can diagnose traumatic brain injury to include any health care professional with pertinent and ongoing brain injury training and experience, says a new congressionally mandated report from the National Academies of Sciences, Engineering, and Medicine.
Vision problems are a common and sometimes lasting consequence of head injuries—from children and teens with sports-related concussions to military personnel with combat-related traumatic brain injury (TBI).
A new study led by researchers at Massachusetts Eye and Ear found that vestibular thresholds begin to double every 10 years above the age of 40, representing a decline in our ability to receive sensory information about motion, balance and spatial orientation.
Two case reports published in The Journal of the American Osteopathic Association document improvements in concussion-related symptoms following an initial session of osteopathic manipulative treatment (OMT).
A new study at Massachusetts Eye and Ear showed that in some cases of vestibular schwannoma, a sometimes-lethal tumor often associated with neurofibromatosis 2 (NF2), secretions from the tumor contain toxic molecules that damage the inner ear.
Researchers from Massachusetts Eye and Ear and the Harvard Medical School/ Massachusetts Institute of Technology's Program in Speech and Hearing Bioscience and Technology have demonstrated that salicylates, a class of non-steroidal inflammatory drugs (NSAIDs), reduced the proliferation and viability of cultured vestibular schwannoma cells that cause a sometimes lethal intracranial tumor that typically causes hearing loss and tinnitus.
If you have ever looked over the edge of a cliff and felt dizzy, you understand the challenges faced by people who suffer from symptoms of vestibular dysfunction such as vertigo and dizziness. There are over 70 million of them in North America. For people with vestibular loss, performing basic daily living activities that we take for granted (e.g. dressing, eating, getting in and out of bed, getting around inside as well as outside the home) becomes difficult since even small head movements are accompanied by dizziness and the risk of falling.
Rehabilitation is essential for patients with disabling symptoms of dizziness, vertigo, and unsteadiness caused by disorders of the vestibular system. A special issue of The Journal of Neurologic Physical Therapy (JNPT) presents an update on new and emerging vestibular rehabilitation techniques, highlighting the physical therapist's role on the multidisciplinary teams providing patient care and research.
An estimated 35 percent of U.S. adults age 40 and older have vestibular dysfunction (inner ear balance disorders), and those who do may have a higher risk of falling, according to a report in the May 25 issue of Archives of Internal Medicine.
According to health care experts, cochlear implantation in senior citizens seems to be not cost effective, due to a belief that elderly patients perform poorly in the postoperative audiological rehabilitation process due to degenerative processes in the central and peripheral auditory system.
