Cognition In General Animal Models: Evidence For Exercise
As mentioned, dementia develops in most patients with PD over the long term, and is often the reason for nursing home placement. The substrate is proliferation of the Lewy neurodegenerative process.e2-e4 Animal studies have not specifically addressed the influence of exercise on proliferation of Lewy pathology. However, the influence of exercise on cognition in intact animals has been extensively studied.
Most animal studies investigating exercise influences on cognition have targeted the hippocampus, obviously a crucial brain nucleus for learning. Note that mice/rats voluntarily run for long durations if provided exercise wheels in their cages. Other research paradigms utilize treadmills to control exercise. The outcomes from such studies in mice/rats have been consistent, with evidence of enhanced neuroplasticity in the hippocampus, especially dentate gyrus. These hippocampal findings induced by exercise include the following:
Elevated expression of BDNF, which appears to be a key factor mediating the effects of exercise on cognitione5-e14
Increased expression of the neuroprotective agent, insulin-like growth factor I, which interacts with BDNF to mediate exercise-induced cognitive gainse15; exercise-induced production of this factor protects against neurotoxic hippocampal insultse16 and is acutely elevated by exercise in normal humanse17
Elevated concentrations of synaptic proteins, synapsin I and synaptophysine11,e12
How Do I Tailor A Parkinsons Exercise Program To My Unique Symptoms
A visit to a physical therapist is a good place to start building an exercise program that is tailored to you. Physical therapists can talk with you about your symptoms and personal goals to design an exercise program that is effective and enjoyable. They can also help you find exercise classes in your area.
Incorporating activities that have been shown to address specific symptoms can help you practice and maintain everyday motor functions that directly impact quality of life. Some exercise principles to consider for your exercise program include:

What Are The Different Stages Of Parkinsons Disease
Each person with Parkinsons disease experiences symptoms in in their own unique way. Not everyone experiences all symptoms of Parkinsons disease. You may not experience symptoms in the same order as others. Some people may have mild symptoms; others may have intense symptoms. How quickly symptoms worsen also varies from individual to individual and is difficult to impossible to predict at the outset.
In general, the disease progresses from early stage to mid-stage to mid-late-stage to advanced stage. This is what typically occurs during each of these stages:
Early symptoms of Parkinsons disease are usually mild and typically occur slowly and do not interfere with daily activities. Sometimes early symptoms are not easy to detect or you may think early symptoms are simply normal signs of aging. You may have fatigue or a general sense of uneasiness. You may feel a slight tremor or have difficulty standing.
Often, a family member or friend notices some of the subtle signs before you do. They may notice things like body stiffness or lack of normal movement slow or small handwriting, lack of expression in your face, or difficulty getting out of a chair.
Standing and walking are becoming more difficult and may require assistance with a walker. You may need full time help to continue to live at home.
Slowing Down The Progression Of Parkinsons Disease
How Often Do Patients Need To Exercise To Benefit
How Do You Start
Seeing a physical therapist specialized in treating Parkinsons patients is the best choice. You may also work with a personal trainer or find a group class for exercise.
Most importantly you should find a type of exercise you ENJOY. Any exercise is beneficial. Some examples:
- Tai Chi or yoga for balance and breathing
- Dancing or boxing for coordination, agility, and balance
- Cycling, walking, or running for aerobic conditioning
- Online classes
There are five stages of Parkinsons disease; it doesnt matter what stage you are in, exercises can be adapted for sitting, standing and even lying down. The most important aspect is moving!!
Theracycle And Forced Exercise
Rock Steady boxers are encouraged by coaches and peers to attempt moves and workout intensities that seem to push the limits of their abilities.
The Theracycle takes this idea a;step further, using a motor that forces patients to pedal the stationary bike faster than they could on their own, theoretically maximizing workout effects.
Jay Alberts, PhD, a biomedical engineer at the Cleveland Clinic and an avid cyclist, went on a 200-mile trip in 2003;on a tandem bike with a friend, who also happened to be a Parkinsons patient. The friend was forced to pedal at Alberts pace, which was about 30 revolutions per minute faster than she would have been able to pedal on her own.; According to Alberts, her tremors disappeared during the ride and for a period of time afterward.;
Alberts brought another patient on his tandem bike and noticed similarly striking results.;
But requiring a strong cyclist to take patients out on tandem bike rides regularly is not a practical treatment plan for 10 million patients worldwide.
The Theracycle, a motorized stationary bicycle based on the exercycle;invented in 1932, gives patients a safe way to engage in forced exercise exercise where, in this case, a motor helps them pedal at a speed they wouldnt be able to reach on their own at home without a tandem bike or partner.
Both regimens have one thing in common pushing patients to do more than they may think they are capable of doing.
What Kind Of Exercise Can I Do If I Have Trouble Standing Or Walking
Even with advanced Parkinsons symptoms, you can still reap the benefits of some activities. If you have trouble walking or balancing, hold a bar or rail to exercise and stretch. If standing or getting up is tough, exercise and stretch in a chair or bed. Physical exercise performed in a seated position, such as biking on a recumbent bike can allow you to exert yourself in a safe manner.
Facial exercises may help combat difficulties speaking or swallowing:
- Chew your food longer and more vigorously.
- Exaggerate your face and lip movements when you speak.
- Make faces in the mirror.
- Sing or read out loud.
Mental exercises give your brain a workout and can improve memory. For example:
- Name as many animals as you can in 1 minute.
- Play brain games and do puzzles.
- Solve math problems in your head.
You can also add activity in small bits throughout your day:
- Park further away from stores so you walk longer distances.
- Stretch or do leg exercises while watching TV.
- Swing your arms more when you walk, and take long strides.
- Take the stairs instead of the elevator.

A Completely New Way To Replace Lost Cells
Parkinson’s UK Deputy Director of Research David Dexter said:
“Replacing the cells that are lost in Parkinson’s is a possible way to reverse its symptoms, and could one day be a cure for the condition.
“This research is hugely promising, as it offers a completely new way to replace cells that are lost in Parkinson’s.
“However, the location of the new cells created through this process could make it difficult to control the delivery of dopamine to the brain.
“Further development of this technique is now needed, so it encourages dopamine to be produced and released in a controlled manner, like the original brain cells.
“If successful, it would turn this approach into a viable therapy that could improve the lives of people with Parkinson’s and, ultimately, lead to the cure that millions are waiting for.”
What Does A Parkinson’s
Its important to practice Parkinsons specific exercises rather than general exercise training to improve movement because of the type of brain stimulation each type of exercise produces.
Your brain has the ability to help you move better. It learns from all stimulation applied to it, including exercise, and has an enormous capacity to re-wire the neural connections for improved movement. You may not have noticed, but, getting off a low chair, rolling in bed and picking up a cup of water all require infinite amounts of fine-tuning as your brain prepares, conducts and evaluates the task. Your brain is receiving constant feedback about the environment so that it can move with the appropriate amount of speed, power and accuracy to be effective and efficient.
Dopamine deficiency can lead to the continuing reduction of movement, speed and power. Instead of getting up from the chair first time round, it may mean that you have to use your arms to push up, or rock back and forth a bit to get enough momentum to stand up. It is the chronic reduction in a movement that makes big movements like walking and small movements like writing so challenging.
Parkinsons specific exercise will teach you how to move with amplitude, power and speed in everyday tasks so that you can get back to doing the things you enjoy doing. By increasing your overall activity level, Parkinsons specific exercise may also slow down the symptom progression of your Parkinsons.

Molecular Mechanisms For The Benefits Of Exercise
Animal studies suggest several different mechanisms in which exercise leads to neuroprotective effects and promotes neuroplasticity. Neuroplasticity, defined as the ability of neuronal circuits to make structural and functional adaptive changes, can be induced by exercise and effect the nigrostriatal and related motor circuits that are involved in the pathophysiology of PD.3,4 Endurance exercises promote neurogenesis and neuroprotection in animals.9 Several studies have shown that exercise exerts neuroprotective effects against dopaminergic neurotoxins 6-hydroxydopamine and 1-methyl,4-phenyl,1,2,3,6-tetrahydropyridine .10,11 In a transgenic mouse model of diffuse Lewy body disease, mice that exercised for 3 months had significantly less -synuclein aggregation than in the brains of sedentary mice.12 These findings suggest that in animal models of PD, exercise has neuroprotective effects.
Exercise has been shown to increase dendritic length and complexity and dendritic spine density within the hippocampus. Exercise increases expression of genes associated with neuroplasticity and downregulates genes linked to oxidative stress.3 In a study involving a transgenic mouse model of Alzheimers disease , 5 months of exercise significantly reduced brain amyloid concentrations.3,14 These changes are associated with improved performance in spatial memory and object recognition.3
Cell Replacement In Parkinson’s
Parkinson’s is caused by the loss of dopamine producing brain cells. Dopamine is used to help the brain communicate messages about movement, but as these cells are lost the brain cannot control movement effectively.
If successful, it would turn this approach into a viable therapy that could improve the lives of people with Parkinson’s and, ultimately, lead to the cure that millions are waiting for.
There are currently no treatments that can slow or stop Parkinson’s, but cell replacement could help to reverse the condition.
Ongoing research in people with Parkinson’s is attempting to transplant pre-made cells into the right part of the brain.
The study shows that;astrocytes, a type of cell that supports other brain cells and is not affected in Parkinson’s, could be turned into dopamine-producing cells inside the brain. This could pave the way to replacing the cells lost in Parkinson’s without the need for a transplant.
Best Physical And Occupational Therapy Exercises
Physical therapy exercises target your areas of concern. They can help develop your strength, balance, and coordination. Youll also enhance your functional mobility by improving concentration, flexibility, and range of motion.
Occupational therapy exercises are intended to help you perform daily activities related to work, school, or home with greater ease.
Frequently Asked Exercise Questions
Q: If one part of my body needs more attention what should I do?
If you have noticed more symptoms in one particular arm or leg, you may wish to focus on that limb more intensively during each exercise station. Make sure that the particular limb you are focusing on is leading the exercise in effort and amplitude and that you have symmetry between both sides. You may also wish to double the repetitions on that side, especially if there is a marked difference from one side to the other.
Q: How do I avoid injuring myself?
It is really important that you warm up first and follow the instructions for each exercise to avoid injury. If you are just starting out, be gentle on yourself, especially if you are new to exercise or dont exercise regularly.; As you become more confident with the exercises you can start to work towards an effort level of 80% and full range of movement weight shift and amplitude. If anything hurts while you are doing the exercises or you feel unbalanced stop immediately. All of the exercises can be modified to be made easier as well as harder so listen to your body.
Q: What about my medication. Is there a better time to do the exercises?
Q: What Clothing & Footwear Should I Wear?
Wear loose, comfortable clothing that breathes well. Layers may help if you have extremes of temperature where you train or are prone to overheating. Your footwear needs to be supportive such as trainers or walking shoes.

What Is Parkinsons Disease
Parkinsons disease is a neurological condition afflicting about one percent of men and women over the age of seventy years old.
Individuals with Parkinsons disease have tremor of the hands, rigidity, poor balance, and mild intellectual deterioration. The tremor is most apparent at rest and is less severe with movement. Shaking or tremors are an early symptom of Parkinsons disease. Progression leads to trembling in arms, legs, jaw, and rigidity or stiffness of the limbs.
Research has shown that Parkinsons disease occurs when a small region in the brain, called the substantia nigra, begins to deteriorate. The neurons of the substantia nigra use the brain chemical dopamine. Tremors begin to happen and movement slows when you have inhibited dopamine function.
Dopamine is broken down in the brain by an enzyme called monoamine oxidase . When the activity of MAO is inhibited, dopamine stays around longer, and this is beneficial to those with Parkinsons disease.
Dr Jay Alberts Discovers The Magic Of Forced Exercise For Parkinsons Patients
In 2003 Dr. Jay Alberts rode the Des Moines Registers Annual Great Bike Race Across Iowa with his friend Cathy, who has Parkinsons disease. Dr. Alberts rode the front of a tandem bicycle with Cathy pedaling behind him. Cathy remarked, for this week it did not feel like I had Parkinsons. After several days of riding, Dr. Alberts noticed that Cathys motor control, most notably her handwriting, had improved. This set him on a path toward groundbreaking research on the benefits of forced exercise for Parkinsons patients.
When the effects of exercise are tested in animal models of Parkinsons, the exercise is often forced, meaning that the animal is forced to exercise at a more intense level than they would choose to on their own. Researchers have found that this forced exercise is far more effective than voluntary exercise in stimulating the release of neurotrophic factors and enhancing neurogenesis. Researchers suggest that contradictory results in human and animal studies are caused by differences between voluntary versus forced exercise patients with PD may not be able to exercise at sufficiently high rates to trigger the endogenous release of the neurotrophic factors thought to underlie global improvements in motor function.

Exercise And The Rate Of Pd Motor And Non
Exercise may also be disease-modifying in fully manifest PD as well as in prodromal and preclinical stages. Longitudinal cohort studies have demonstrated that exercise can be a predictor of slower progression of both motor and non-motor symptoms. In the population-based Parkinsons Environment and Gene study in central California, Paul et al. evaluated the association between physical activity and progression of both motor and non-motor symptoms in 244 subjects with early PD . They analyzed the subjects history of ever having participated in competitive sports and their overall physical activity level, in metabolic-equivalent hours per week , across 4 age periods of adulthood. Over 5.3 years of follow-up they observed that those with a history of competitive sports were less likely to suffer a 4-point decline on the Mini-Mental State Exam , or convert to stage 3 on the Hoehn and Yahr scale of motor disability . There was also a trend between higher MET-h/week and slower progression on MMSE and conversion to Hoehn and Yahr stage 3, with HR 0.71 , and 0.73 , respectively, .
What Is Needed For A Parkinsons Disease Dementia Diagnosis
There is no definitive medical test that confirms cognitive decline or dementia in Parkinsons disease. The most accurate way to measure cognitive decline is through neuropsychological testing.
- The testing involves answering questions and performing tasks that have been carefully designed for this purpose. It is carried out by a specialist in this kind of testing.
- Neuropsychological testing addresses the individuals appearance, mood, anxiety level, and experience of delusions or hallucinations.
- It assesses cognitive abilities such as memory, attention, orientation to time and place, use of language, and abilities to carry out various tasks and follow instructions.
- Reasoning, abstract thinking, and problem solving are tested.
- Neuropsychological testing gives a more accurate diagnosis of the problems and thus can help in treatment planning.
- The tests are repeated periodically to see how well treatment is working and check for new problems.
Imaging studies: Generally, brain scans such as CT scan and MRI are of little use in diagnosing dementia in people with Parkinsons disease. Positron emission tomographic scan may help distinguish dementia from depression and similar conditions in Parkinsons disease.
