Vestibular balance

HEALTH INFORMATION

Correcting issues of the vestibular system

WHAT WE KNOW

The vestibular system includes the parts of the inner ear and brain that help control balance and eye movements. Our visual system works with our vestibular system to keep objects from blurring when our head moves and to keep us aware of our position when we walk or when we ride in a vehicle. The system may be damaged by disease, aging, or injury.

The vestibulo-ocular reflex (VOR) is important for maintaining visual stability during tasks that move the head rapidly and unpredictably, for example, as occurs during running or when driving on a bumpy road. The vestibular organs, one in each inner ear, sense rotational and linear head motion and move the eyes to compensate for passive head movements. The vestibular organ can be damaged by disease, degenerative conditions and by chemical or surgical interventions. When both vestibular organs are damaged it can be severely debilitating. The research in this laboratory has two closely related goals: 1) to understand the signal processing mechanisms that control the VOR by analysing vestibular-evoked eye movements and single-unit (vestibular nerve) recordings; and 2) to apply this knowledge of basic vestibular physiology to the diagnosis and treatment of balance disorders in humans.

OUR LATEST RESEARCH

Treating dizziness in older people

Despite effective treatments being available, up to 40% of older people with reported dizziness remain undiagnosed and untreated. A multidisciplinary assessment battery, with new validated assessments of vestibular impairments is required for diagnosing and treating older people with dizziness. This project will therefore aim to conduct a randomised-control trial of a multifaceted dizziness intervention based on a multidisciplinary assessment, and develop a multiple profile assessment of dizziness for use in Specialist Clinics.

Development of a take-home rehabilitation device that improves vision and balance in patients with i

This project will develop a rehabilitation device based on a training technique we invented, which has been shown to significantly normalise the vestibulo-ocular reflex (VOR) response in patients with vestibular organ lesions.

A new mouse model that determines the effects of a unilateral vestibular prosthesis on vestibular pl

Much like a cochlear implant restores auditory function, a vestibular prosthesis restores balance function. It is not clear whether the limited results from vestibular prostheses is due the device not stimulating one component (the otoliths) of the vestibular system essential for self-repair.

The effect of enhanced vestibular efferent transmission on plasticity of the mammalian vestibulo-ocu

We have identified a nerve-pathway crucial for balance adjustment and self-repair. We will test a mouse type that has this pathway genetically made more sensitive to determine whether stimulation of this pathway is a viable approach to improving recovery after balance loss in humans.

What else is happening in Vestibular balance research at NeuRA?

FEEL THE BUZZ IN THE AIR? US TOO.

During three decades on Australian television, two simple words brought us to attention.

‘Hello daaaahling’. Outrageous, flamboyant, iconic – Jeanne Little captivated Australians everywhere with her unique style, cockatoo shrill voice and fashion sense. "Mum wasn't just the life of the party, she was the party.” Katie Little, Jeanne’s daughter remembers. This icon of Australian television brought a smile into Australian homes. Tragically, today Jeanne can't walk, talk or feed herself. She doesn't recognise anyone, with a random sound or laugh the only glimpse of who she truly is. Jeanne Little has Alzheimer's disease. The 1,000 Brains Study NeuRA is very excited to announce the 1,000 Brains Study, a ground-breaking research project to identify the elements in our brains that cause life-changing neurodegenerative diseases like Alzheimer’s, Parkinson’s and other dementias. This study will focus on the key unresolved question: why do some of us develop devastating neurodegenerative diseases, while others retain good brain health? The study will compare the genomes of people who have reached old age with healthy brains against the genomes of those who have died from neurodegenerative diseases, with post mortem examination of brain tissue taking place at NeuRA’s Sydney Brain Bank. More information on the study can be found here. Will you please support dementia research and the 1,000 Brains Study and help drive the future of genetics research in Australia? https://youtu.be/q7fTZIisgAY
