Deep brain stimulation and exercise restore movement in ataxia

New research from scientists at Baylor College of Medicine shows that a combination of deep brain stimulation (DBS) and exercise has potential benefits for the treatment of ataxia, a rare genetic neurodegenerative disease characterized by progressive, irreversible problems with movement.

Working with a mouse model of the human condition, researchers at Baylor and the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital found that the combination of DBS targeting the cerebellum, a major motor center in the brain, and the exercise saved the coordination of limbs and walking. and that the benefits continued without further stimulation. In addition, the study reports that stimulation of mice with ataxia at an early stage showed the most dramatic improvements. These and other results, published in the journal Nature communications, provide valuable new information in the design of future DBS strategies to treat the human condition.

“People with ataxia usually have progressive movement problems, including balance and coordination problems that affect a person’s ability to walk, speak and use fine motor skills. There are limited treatment options for this condition, and patients typically survive 15 to 20 years after symptoms. appear for the first time, ”said first author Lauren Miterko, a graduate student of Dr. Roy Sillitoe’s lab at Baylor.

DBS is currently used to relieve motor dysfunction in Parkinson’s disease and other movement conditions, but its value in the treatment of ataxia has not been widely explored. In this study, the researchers worked with Car8, a mouse model of inherited ataxia to determine whether adjusting DBS parameters and the location of the stimulation target would help increase the effectiveness of treatment for the disease.

Frequency matters

“We first targeted the cerebellum because it is a primary motor center in the brain and this target location for DBS has seen encouraging success in treating motor problems associated with other conditions, such as stroke. “said Miterko. “We systematically targeted the cerebellum with different frequencies of DBS and determined if there was an optimal frequency that would increase the effectiveness of the treatment. When we used a particular frequency, 13 Hz, that’s when the function motor movement improved in our Car8 mice. ”

DBS plus exercise improved results

Neurostimulation with DBS improved muscle function and general mobility in Car8 mice, but researchers looked for additional ways to improve the condition.

“We know that exercise in general can benefit both muscle and neuronal health, and previous work in Parkinson’s disease and stroke patients has mentioned that neuromodulation techniques combined with physical stimulation had benefits, so we decided to include exercise in our investigation, ”Miterko said. “We found that when animals received DBS during exercise on a treadmill, there were improvements in motor coordination and gait that we did not see with DBS alone.”

“In our model of ataxia, the improvements did not disappear after a week of treatment, which has important practical implications for potential clinical applications,” said co-author Dr Meike E. van der Heijden, Associate postdoctoral fellow at the Sillitoe laboratory. “Additionally, all of the young mice with early-stage ataxia responded, suggesting that it is possible that early treatment may also offer the greatest benefit to patients in the future.

The researchers also obtained information on the type of brain cells involved in the process of restoring movement in this mouse model of ataxia. They found that neurotransmission of Purkinje cells is necessary for DBS to be effective. Purkinje cells are a type of neuron located in the cerebellar cortex of the brain. These cells are involved in the regulation of movement, balance and coordination among other functions.

“One of our goals is to better elucidate the role Purkinje cells play in recovery from ataxia,” said van der Heijden.

“We are particularly excited by the results of this study as it is possible to extrapolate our approach to treat not only other motor diseases, but possibly non-motor neuropsychiatric conditions as well,” said the corresponding author, the Dr Roy Sillitoe, Associate Professor of Pathology. and Immunology and Neuroscience at Baylor College of Medicine, and Director of the Center for Neuropathology at the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital.

  27. I have been examinating out a few of your posts and i can claim clever stuff. I will definitely bookmark your website.

  28. I have been exploring for a little bit for any high-quality articles or weblog posts in this kind of area . Exploring in Yahoo I eventually stumbled upon this web site. Studying this information So i am glad to show that I have an incredibly good uncanny feeling I found out exactly what I needed. I most without a doubt will make certain to don抰 forget this website and give it a look on a relentless basis.

  29. I just could not depart your website prior to suggesting that I really enjoyed the standard information a person provide for your visitors? Is gonna be back often to check up on new posts

  30. I appreciate, cause I found exactly what I was taking a look for. You have ended my four day lengthy hunt! God Bless you man. Have a nice day. Bye

  31. Interesting post here. One thing I would like to say is most professional fields consider the Bachelor Degree as the entry level standard for an online college degree. Whilst Associate Diplomas are a great way to begin with, completing the Bachelors presents you with many entrance doors to various employment goodies, there are numerous online Bachelor Diploma Programs available coming from institutions like The University of Phoenix, Intercontinental University Online and Kaplan. Another thing is that many brick and mortar institutions offer you Online versions of their college diplomas but typically for a considerably higher charge than the companies that specialize in online degree programs.

  32. I think this is one of the most significant information for me. And i’m glad reading your article. But should remark on some general things, The site style is wonderful, the articles is really nice : D. Good job, cheers

  33. Thanks for this glorious article. One other thing is that almost all digital cameras can come equipped with some sort of zoom lens that enables more or less of your scene to be included by way of ‘zooming’ in and out. Most of these changes in focusing length tend to be reflected inside the viewfinder and on big display screen right on the back of the exact camera.

  34. I am grateful for your post. I’d like to write my opinion that the tariff of car insurance varies from one plan to another, due to the fact there are so many different issues which contribute to the overall cost. For example, the brand name of the automobile will have a large bearing on the cost. A reliable outdated family automobile will have a lower priced premium than the usual flashy fancy car.

  35. You are really a good webmaster, you have done a well job on this topic!

  36. That is very attention-grabbing, You are an excessively professional blogger. I have joined your feed and stay up for seeking extra of your excellent post. Additionally, I’ve shared your website in my social networks!
