Deep Brain Stimulation (DBS)is a surgical treatment for movement disorders such as Parkinsons disease (PD), essential tremor (ET) and dystonia. In Parkinsons disease, DBS is best suited for patients whose medication fails to provide adequate symptom control or in whom medications cause intolerable side effects.
Parkinsons patients who undergo DBS typically experience a dramatic reduction in their medications and more consistent motor function. They typically have a more fluid movement without the highs and lows of medications wearing off. DBS will reduce rigidity, improve bradykinesia (slowness), improve akinesia (freezing) and diminish tremors. The dyskinesias usually resolve due to medication reduction. DBS is also very effective for patients with essential tremor, eliminating the need for medications and reducing tremor by 60-90%.
DBS provides a constant, high frequency electrical signal to a specific area of the brain, which overrides the abnormal circuitry in the brains of patients with movement disorders, providing therapeutic benefits for many symptoms associated with these diseases.

My condition is not bad enough to necessitate DBS.
In Parkinsons disease, there is a window of opportunity wherein one can undergo DBS. If a patient has progressed to moderate or severe dementia, DBS is not an option. Furthermore, DBS is appropriate when medication still has a positive effect but is becoming less reliable, or, when side effects are intolerable. Once medications are ineffective, DBS will not be a treatment option. One should inquire about DBS when PD symptoms and effectiveness of medications change, and before dementia sets in. A neurosurgeon or neurologist can help to monitor your symptoms. DBS does not cure PD, and if it progresses we can fine tune programming for continued effectiveness.
DBS is experimental and should be used as a last resort.
DBS has been approved in the US for more than 10 years, since 1997. There are over 100,000 patients with DBS worldwide. In the case of essential tremor, the American Academy of Neurology recommends DBS for a 60-to-90 percent improvement in limb tremor. For PD, DBS has now been proven to provide better motor symptom control than medications alone, as well as lead to reductions in medication and improved quality of life. The risks of DBS are too high. The rate of infection for this procedure is three-to-five percent over the course of a patients lifetime. The risk of stroke is less than 1%. This procedure has been proven to be safe and effective in the treatment of Parkinsons disease, dystonia and essential tremor. It is in fact the gold standard in treatment of Parkinsons disease. There is minimal post operative pain and most patients spend only one night in the hospital.
The battery needs to be replaced often and will include an invasive procedure.
Generator replacement takes 15 minutes, can be accomplished under local anesthesia and is done every three-to-five years on average.
Once I have DBS I cannot try any new treatments in the future.
DBS is reversible and if more advanced treatment options for movement disorders become available, all of the hardware can be removed. DBS only works for tremor. DBS also helps with stiffness, slowness and freezing associated with movement disorders such as PD, and is also effective for essential tremor and dystonia If my doctor hasnt recommended DBS I must not be a good candidate. Often medical doctors may not recommend procedures they are not familiar with and they may not be educated on this advanced technology. If you have questions about DBS you can schedule a consultation with a neurosurgeon to evaluate your candidacy. You can also ask your doctor if this therapy might be right for you.
I cannot afford DBS.DBS is covered by all major insurances, including Medicare and Medicaid

What Can Cognitive Screening Show (and When Should You Get It?

Growing older comes with outward signs of aging that you might find difficult to accept. Spotty skin, graying hair, and an achy body arent exactly perks of aging. But changes are unavoidable, even when it comes to your brain.Did you realize that your brain shrinks with age? This process begins as early as your 30s and 40s. This shrinkage also affects your learning and memory center, known as the hippocampus. Age-related decline also decreases blood flow to your brain while increasing inflammation. Communication between nerve cells (neurons) becomes less effective as you age.While you might not look or feel as well as you once did, your brain is also experiencing changes. While this might all seem bleakits just a normal part of aging most of the time. Age-related cognitive decline happens gradually for most people.Sometimes neurodegenerative changes arent arent so normal in older adults. Cognitive screens at the right time can help you catch declines early and even address underlying causes to slow or reverse these negative changes.What Is Mild Cognitive Impairment (MCI)?MCI is an early stage of declining cognitive (thinking) function. It usually involves some degree of memory or language loss that is greater than expected at someone's age or health. When you have MCI, you can function in daily life without help, but symptoms can progress until theyre no longer mild. You may eventually require assistance with daily tasks.Although MCIs exact cause isnt known, its apparent that certain processes in the brain trigger toxic clumps of proteins to collect, allowing other toxic proteins to damage and kill neurons. For some, this decline is connected to the early stages of dementia or Alzheimers, which are considered more advanced cognitive impairment that includes functional impairment (or loss of abilities).Of course, age increases your risk of MCI but so does a genetic predisposition to Alzheimers. Other medical conditions like high blood pressure, diabetes, and depression are also MCI risk factors.The Benefits of Cognitive ScreeningEarly detection can be key to stopping or reversing neurodegeneration. Cognitive screening can help you catch negative changes before they cause serious problems. Often, abnormal cognitive decline has underlying causes that can be addressed, such as medication side effects or nutritional deficiencies. And both lifestyle changes and new medications can slow the progression of dementia if detected in the early stages.What Is Cognitive Screening?Cognitive screening includes testing assesses different aspects of your mental functions with the purpose of detecting any problems with thinking, memory, problem solving, language, and other cognitive abilities.This type of screening is usually brief, like a questionnaire. But its not used to diagnose a condition and is instead a means of determining if you need further evaluation to make a diagnosis. It's evaluating whether youre experiencing difficulty with mental functions before you or those close to you notice there is a problem. Think of it as a pre-assessment or preliminary step.When Is the Best Time for Cognitive ScreeningBest rule of thumb: dont wait. Once youre noticing memory problems that are disrupting your life, youre already past the screening stage. At that point, its time for diagnostic testing to determine the specific cause and treatment. You should get a screening to make you aware of what is not yet noticeable, something that might be lurking but correctable, something to be addressed to prevent further decline.You might wonder when to get your first assessment. Its reasonable and worthwhile to get one at age 65 when you enroll in Medicare. It should be included in your annual wellness checkup, but be sure to confirm this or ask your doctor. This is especially if you havent had any symptoms prior to age 65. But if youre in tune with your body and feel like something is off, even without obvious symptoms, its reasonable to get screened prior to 65.Your primary care physician can perform a cognitive screening if there is no reason why you should see a specialist.What Is the Cognitive Screening Process?Its typically about 10 minutes or less and covers three assessments:Montreal Cognitive AssessmentMini-Mental State ExamSaint Louis University Mental State ExamYou can expect to be asked brief questions without any prior preparation. For example, during the Mini-Mental State Exam, you will be given three words and are asked to repeat them after a few minutes. You will also need to draw a circular clock and position the hands at a specified time. Other tests assess your orientation to ensure you know the date, your name, and where you are. These tests include questions to evaluate your:Attention spanShort-term learning abilitiesBoth short- and long-term memoryConcentrationLanguage abilitiesThese screenings are designed to assess different areas of brain function.Can You Do Online Screenings at Home?The most reputable, do-it-yourself, online cognitive screening is the Self-Administered Gerocognitive Exam (SAGE). Its a short, written exam that can be taken at home and doesnt require a trained professional to administer. It takes about 10-15 minutes to complete. It measures a range of abilities like reasoning, memory, language, and orientation.However, you dont get immediate results, because you dont determine the results yourself. There is no answer key or way to score it on your own. Its designed to be completed and given to your primary care physician who will score it and interpret the results. It will be up to your doctor to determine if you need further examination.What Happens After Cognitive Testing?For many people, cognitive testing yields positive results and requires no further evaluation. But you may need further testing if the screening indicates a degree of cognitive impairment. If this is you, dont panic. Not everyone with mild cognitive impairment (MCI) has or will develop dementia.According to the Mayo clinic, only about 10-15% of people with MCI later develop dementia. Many underlying causes can be addressed, like thyroid problems, sleep issues, and vitamin deficiencies like B12. When you treat these causes, your brain impairment is likely to improve.Sometimes a brain scan is necessary to determine if you have inflammation, tumors, or small strokes. It can also detect infection and structural problems in the brain.What Does an MCI Diagnosis Mean?If you get an MCI diagnosis, you can think of it as the stage between normal cognitive decline (due to aging) and more concerning decline like dementia. But remember, MCI doesnt mean that dementia is inevitable. As mentioned previously, most people with MCI dont move into the more serious state of cognitive decline, known as dementia.But its not easy to distinguish between MCI and the typical effects of aging on the brain. Its not uncommon for doctors to completely miss an MCI diagnosis. While having MCI is a risk factor for dementia or Alzheimers disease, these conditions arent inevitable. Its possible for your MCI symptoms to remain the same or improve.Talk to your doctor about lifestyle changes that can help slow declining mental function.Recommended Lifestyle Changes for Improved Brain HealthBoosting brain health means taking steps that improve your health in general. In fact, youve probably heard most of these recommendations before.Quality and sufficient sleepExerciseNutritious dietSocializationThis is not headline news, but adopting these healthy habits can have a notable impact on your cognitive health. For instance, sleep is crucial, because during this time your body removes toxins from your brain, which is key to preventing dementia and Alzheimers.Concerning diet, experts recommend a Mediterranean-style diet for brain function. This would include diets like the original Mediterranean Diet, the MIND Diet, and the Mediterranean-DASH Intervention for Neurodegenerative Delay). These eating plans involve less red meat and more produce. People who eat according to these plans have fewer signs of Alzheimers according to a study sponsored by the National Institute on Aging.Despite the importance of all these lifestyle factors, the addition of exercise has the strongest evidence for improving various cognitive functions. This is according to a review of 65 research studies.What If You Need Medication for MCI?Sometimes, it takes more than lifestyle changes to effectively battle MCI and stave off early on-set Alzheimers disease. Medications can help slow both MCI and Alzheimers, but this is a decision for you to make with your doctor.Medication to consider include:aducanumab (Aduhelm)lecanemab (Leqembi)donanemab (likely to be approved soon)You and your doctor can weigh the benefits of medication against the side effects.Cognitive Screening Is a Tool Worth UsingWhen you turn 65 and are enrolled in Medicare you can take advantage of cognitive screening during your annual wellness visit. The cost should be included in the annual exam. But not all seniors get their annual physical and miss this free cognitive screening. And some who do get an annual physical through Medicare claim they never got the screening. Be sure to ask about cognitive screening when you schedule your annual physical with your Medicare plan.You can be proactive in preventing mild cognitive impairment and the onset of dementia but there are no guarantees. Cognitive conditions like dementia and Alzheimers have a genetic component that you cannot change. But you may be able to delay the onset with good lifestyle habits like regular exercise, good sleep, socialization, and a Mediterranean-style diet.TYE Medical offers premium incontinence products in a variety of sizes and absorbency levels.

Community Benefit Statement at Via Mobility

You may have first experienced our nonprofit organization as a provider of paratransit services to the elderly and people with temporary or permanent disabilities. Or perhaps you became familiar with Via without even knowing who we are as you rode on the City of Boulder HOP bus route. This service has been operated and maintained by Via since 1994. Initially envisioned by the City and Via, the route makes it possible to get from the University of Colorado campus to the historic Pearl Street shopping district, and the 29th Street shopping and entertainment area without getting into a car. Via has also operated FlexRide, formerly Call-n-Ride, and Access-a-Ride services for RTD for many years. We also operate well-loved commuter micro transit routes such as the Lyons Flyer, HOP to Chautauqua, RideFree Lafayette, and the Omnibus for the City of Littleton. While initially headquartered and focused in Boulder County, Via has grown into Broomfield, Larimer, Weld Counties, and in 2020, on short notice, we took over from a Wheat Ridge based nonprofit that provided services to the mobility handicapped throughout the Denver metro area that had decided to end its paratransit service. This brought Vias signature door-through-door service to the four-county Denver area. When local government contracts with Via for shuttles or other public transit, there are several unique benefits that we provide at no additional cost.These include:1. REINVESTMENT IN COMMUNITY PARATRANSITVia directs the earned income from our contracts into affordable paratransit services for that community. This revenue, combined with other funding, is used to leverage additional federal and state grants, vastly increasing the services provided to our communities. This is unique to Via, as no other service provider reinvests its earned income to increase and expand necessary mobility services to our most vulnerable community members.2. PUBLIC DOLLARS REMAIN IN THE COMMUNITYAs a community-based nonprofit organization, Via works hard to be an efficient and cost-effective operation. We invest over 85 percent of our resources on direct program support; our revenues are reinvested in our communities, our employees, our facilities, and our sustainability programs and are not diverted to remote shareholders.3. CRISIS RESPONSE & COMMUNITY SAFETYWhen local government contracts with Via we offer our First and Second Crisis Response services. Via provided emergency response evacuations to residents during the 2013 floods and multiple wildfire events over the years, including the Marshall Fire in 2022. Via has been recognized by the Boulder County Sheriffs Office as a heroic and vital component of the Office of Disaster Management. Via is not paid for these services, but we underwrite the costs as a community reinvestment.4. PUBLIC ACCESS PARTNERSHIPSA further community benefit of working with Via includes access to our facilities: our 12-acre east Boulder campus is available to be used as a crisis center and public meeting space. In the aftermath of the horrific King Soopers killings, Via quickly organized our facility into a crisis response center where families could meet privately with law enforcement, counselling, and other critical resourcesVia is there for the community.5. ENVIRONMENTAL SUSTAINABILITY LEADERSHIPVia has been a leader in and is committed to Environmental Sustainability and will be fully converting our fleet to zero emission vehicles. We are also partnering with the City of Boulder and Boulder County to continue to build out our on-site solar microgrid. We coordinate closely with our local government partners to ensure that we represent their policies and priorities in the services we offer and the way we conduct our business.6. WORKFORCE TRAINING & DEVELOPMENTVia recently launched a relationship with CareerWise Colorado to begin our first auto mechanic apprenticeship program in 2024 with student employees. It is our goal to mentor and train young people in the newest emerging battery electric and hydrogen technologies, and then be able to offer a full-time, market-based position following graduation.Why Partner with Via Mobility Services?Via Mobility Services is a vital partner for your local government.Despite our many strengths, it would be increasingly difficult for Via Mobility Services to compete head-to-head with national and international for-profit companies intent on entering the market with a strategy of losing money but gaining market share. This is a reality that we face, but when local and county governments fully understand our business model and policy direction, the advantages of a partnership with Via Mobility Services are clear. Thank you for choosing to work with us!

Resources for Social Distancing

Older adults and people with disabilities experience the adverse side effects of social isolation at a higher rate than the average American. Humans are social creatures, and plenty of those we serve are already far too familiar with the struggles of social isolation. Access to affordable, accessible transportation removes one of the many barriers to staying connected that people limited mobility options face. But transportation is only one part of a more extensive network of services that people need.As we being to face the realities of the novel coronavirus, COVID-19, we are all being encouraged to practice social distancing to help stop the spread of this disease. Were acutely aware of the challenges that those in isolation, whether by choice or necessity, face, and we understand that this is an uncertain and stressful time. At Via, we have already seen a decline in ride requests as our riders decide to stay home. Over the past week, senior and recreation centers, adult day facilities, and public events and spaces have made the difficult decision to close or reduce hours as a precaution to help minimize the effects of this outbreak in our community. You can learn more about Vias response here. We have compiled a list of resources to help you and your loved ones access the services you need, and weve included some other ideas of how everyone can stay connected and engaged.If you have any resources that you would like to share, we would love to hear from you! Please email your ideas and resources to so we can add them to this list.
