Research Is Underway To Further Understand The Cardiac Effects Of Parkinsons
It is possible to image the sympathetic nervous system of the human heart by injecting a radioactive tracer, meta-iodo-benzyl-guanidine, . Development of this technique, known as MIBG cardiac imaging, holds much promise as a test to confirm the diagnosis of PD , to identify those who are at risk of developing PD in the future, and to distinguish PD from related disorders. MIBG cardiac imaging is still considered an experimental procedure for detection of PD and is not yet in use as a clinical tool for this purpose.
A recent research study was conducted in monkeys in which the destruction of the sympathetic nerves of the heart was chemically induced to mimic the changes that are seen in PD. The cardiac system was then imaged using a number of new-generation radioactive tracers, which bind to markers of inflammation and oxidative stress. This model system may help to shed light on the molecular changes that accompany the loss of the sympathetic nerves of the heart and can also be used to track the response of the cardiac system to therapeutic agents.
How Is Parkinsons Disease Treated
There is no cure for Parkinsons disease. However, medications and other treatments can help relieve some of your symptoms. Exercise can help your Parkinsons symptoms significantly. In addition, physical therapy, occupational therapy and speech-language therapy can help with walking and balance problems, eating and swallowing challenges and speech problems. Surgery is an option for some patients.

Vyvanse And The Circulatory And Respiratory Systems
One of the more common cardiovascular system side effects is a slightly faster heart rate. You may also have a substantial elevation in heart rate or blood pressure, but this is less common. It can also cause cardiac arrhythmias.
Vyvanse can also cause problems with circulation. You may have circulation problems if your fingers and toes feel cold or numb, or if your skin turns blue or red. If that happens, tell your doctor.
Rarely, Vyvanse can cause shortness of breath.
Vyvanse can affect your digestive system. Some of the more common digestive system problems include:

Assessment Of 20s Proteasome Activity
To determine 20S proteasome activity, C2C12 cells were seeded into clear bottom 96 well black plates at the density of 15,000 cells per cm2 and maintained in 100µl The Proteasome-Glo cell-based reagent. Specific peptide substrate Succinyl-leucine-leucine-valine-tyrosine-aminoluciferin , Z-leucine-arginine- arginine-aminoluciferin and Z-norleucine-proline-norleucine-aspartate-aminoluciferin was added into the wells for the assessment of chymotrypsin-like, trypsin-like and caspase-like activities, respectively. 96-well plate was shaken on a plate shaker for 2min at 700rpm and incubated at room temperature for 10min. Plate was read by Proteasome-Glo programme that is pre-installed by manufacturer using GloMax®96 microplate luminometer . Relative light units detected by the machine were normalized to total protein and represented as percentage of control-siRNA transfected values.
Clinical And Ecg Evaluation
Each patient underwent an extensive evaluation including Hoehn & Yahr stage , Unified Parkinsons Disease Rating Scale , and Scale for Outcomes in PD for autonomic symptoms . Medications and comorbidities were recorded, using the Cumulative Illness Rating Scale . Levodopa Equivalent Daily Dose was also calculated. A long term time domain analysis of heart rate variability using 24-h 12-lead ECG recording , encompassing morning and night hours was performed and evaluated according to the NASPE/ESC Task Force in PD patients and age-matched healthy individuals. Both groups were asked to perform normal daily activity excluding intense physical activity. All time domain parameters analysed have been summarized in Table and calculated using cardioscan II software .

Never Try To Treat Your Cough At Home If You Suspect Heart Failure
Attempting to treat your cardiac cough at home with an over-the-counter cough suppressant can be very dangerous for those with heart failure. The active ingredients in some of thesenamely pseudoephedrine and triprolidine-pseudoephedrine can raise blood pressure and cause fluid retentionboth side effects that can exacerbate heart failure,Richard N. Fogoros, MD, a retired cardiologist, tells Verywell Health.
Instead, continue taking any heart medication that has been prescribed to you and reach out to your doctor for immediate evaluation.

Group Comparison Of Hrv
A General Lineal Model was fitted for each voxel of the 3D HRV-BOLD Sync Map , and group comparisons were performed with two different contrasts: patients> controls and controls> patients. For multiple comparisons, we restricted the analyses to the voxels belonging to a 3mm binary mask of brain gray matter. Correction for multiple comparisons was performed with a cluster-based thresholding method using 3dClustSim of AFNI 19.3, which uses a Monte Carlo simulation with 10,000 iterations to estimate the probability of false positive clusters. After group comparison for each of the HRV metrics, the Fishers statistics was used to pool together the different pi values, each one obtained for a different WL. Thus, assuming k different WLs, the individual pi values for each voxel were transformed into a chi-squared statistic of 2k degrees of freedom, following \. Although the goodness of this procedure requires independence in the different observations providing the pi values, and this was not generally fulfilled as in our case corresponded to different WL-dependent HRV metrics, our strategy achieved to pool all the group differences WL-maps into a final one, that after Bonferroni-correction, was used for further analyses.

Key Teaching Points
Why Check Heart Rate Variability
- It can identify ANS imbalances. When your system is in fight-or-flight mode, the difference between heartbeats is low as compared to when you are in a relaxed mode where the difference between the heartbeats is high.
- HRV can detect stress levels. People with low HRV can easily experience acute stress while people with high HRV rarely experience stress and their cardiovascular system is in great shape. Checking your HRV can help you understand how to respond to stress in a healthier way.
- May increase awareness of your lifestyle habits. Checking your HRV is one way you can know if your lifestyle habits are healthy or unhealthy for your heart and a great tool to motivate behavioral change.
- It can detect your reaction to the environment, and emotions. Your nervous system can tell you how you are reacting to your environment, feelings, and emotions when you track your HRV.
- Can increase your self-awareness. HRV measurements can help increase your awareness of how you live and think, and how your behavior affects your nervous system and bodily functions.

Parkinsons Disease: Causes Symptoms And Treatments
Parkinsons disease is a brain disorder that causes unintended or uncontrollable movements, such as shaking, stiffness, and difficulty with balance and coordination.
Symptoms usually begin gradually and worsen over time. As the disease progresses, people may have difficulty walking and talking. They may also have mental and behavioral changes, sleep problems, depression, memory difficulties, and fatigue.
While virtually anyone could be at risk for developing Parkinsons, some research studies suggest this disease affects more men than women. Its unclear why, but studies are underway to understand factors that may increase a persons risk. One clear risk is age: Although most people with Parkinsons first develop the disease after age 60, about 5% to 10% experience onset before the age of 50. Early-onset forms of Parkinsons are often, but not always, inherited, and some forms have been linked to specific gene mutations.
What Is Congestive Heart Failure
Congestive heart failure is a condition in which the heart becomes enlarged, often due to high blood pressure or narrowing of the coronary arteries.
It leads to an increase in blood volume being pumped out of the left ventricle with each contraction. This leads to fluids backing up in the lungs and body, leading to various symptoms. These include breathlessness, weakness, fatigue and coughing. The most serious complication of congestive heart failure is fluid accumulating around the lungs, known as pulmonary oedema or water on the lung.
1. Congestive heart failure is the most common cardiovascular condition in people over 65 years of age.
2. Heart failure has two major causes: cardiovascular disease or acute myocardial infarction.
3. About one third of heart failure cases are due to dilated cardiomyopathy, in which the heart muscle is damaged by abnormal heart muscle cells .
4. About one third of cases are due to left ventricular hypertrophy .
5. About 15% of cases in males and about 75% in females are idiopathic .
The term congestive heart failure refers to a condition in which the heart becomes enlarged, often due to high blood pressure or narrowing of the coronary arteries.
If untreated, congestive heart failure may progress to decreased exercise tolerance and acute deterioration.

How Can We Reduce Mobility Constraints In People With Parkinsons Disease
Over the last few decades, neuroscience has been providing us with exciting new findings regarding the effects of physical exercise on neuroplasticity , neuroprotection and slowing of neural degeneration. In fact, it has been proven that physical exercise can improve brain function in people with neurological disorders.
Aerobic exercise, such as treadmill training and walking programs, have been tested on individuals with Parkinsons Disease and has been shown to improve gait and quality of life in general. However, the type of exercise chosen should take into account a specific program provided by a specialist. The exercise shouldnt, by any means, put the patients physical integrity at risk, especially if the patient is a senior. In order to address complex mobility issues in people with Parkinsons Disease, a therapist could incorporate tasks such as balance training into the patients rehabilitation. These are exercises that challenge sensorimotor control of dynamic balance and gait to improve mobility.
According to a study by Dr. Ergun Y. Uc, of the University of Iowa, the results suggest that
walking may provide a safe and easily accessible way of improving the symptoms of Parkinsons disease and quality of life.
How Much Intensity
There are two ways to monitor your intensity during exercise: Perceived Exertion and Target Heart Rate.
Certain medications have side effects that influence your heart rate and make target heart rate calculations inaccurate. If you are on these medications, you should monitor exercise intensity using the perceived exertion scale.
Exercise benefits you the most when you work at a high intensity, in the Really Hard 7-8 range on the Borg Perceived Exertion Scale. That said, any exercise is better than no exercise! Work at a level that you can sustain, or try intervals. For interval training, youll alternate between really hard exercise and moderate exercise for the length of your workout.
80% Target Heart Rate= x .80
85% Target Heart Rate= x .85

Much of the disease is not in your control, but what is in your control is how physically fit you are when you tackle the disease. People who exercise do better over all.
**As with all exercises, you should check with your doctor before beginning an exercise regime.

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
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!!
Symptoms Of Parkinsons Disease
Parkinsons has four main symptoms:
- Tremor in hands, arms, legs, jaw, or head
- Muscle stiffness, where muscle remains contracted for a long time
- Slowness of movement
- Impaired balance and coordination, sometimes leading to falls
Other symptoms may include:
The symptoms of Parkinsons and the rate of progression differ among individuals. Early symptoms of this disease are subtle and occur gradually. For example, people may feel mild tremors or have difficulty getting out of a chair. They may notice that they speak too softly, or that their handwriting is slow and looks cramped or small. Friends or family members may be the first to notice changes in someone with early Parkinsons. They may see that the persons face lacks expression and animation, or that the person does not move an arm or leg normally.
People with Parkinson’s disease often develop a parkinsonian gait that includes a tendency to lean forward take small, quick steps and reduce swinging their arms. They also may have trouble initiating or continuing movement.
Symptoms often begin on one side of the body or even in one limb on one side of the body. As the disease progresses, it eventually affects both sides. However, the symptoms may still be more severe on one side than on the other.

Characteristics Of The Population
This was an observational, cross-sectional, comparative pilot study carried-out in an ambulatory setting. Non-demented PD patients were consecutively recruited from our department. Patients with suspected atypical or secondary parkinsonism were excluded, as well as those with comorbidities known to influence HRV , or those patients taking drugs that are known to reduce HRV . Similar exclusion criteria were used for healthy controls , who were matched 1:1 for sex and age to PD patients. All the participants gave their informed consent to participate in the study. The study was approved by the local ethics committee and conducted according to the principles of the Declaration of Helsinki.
During the study period, 127 patients were evaluated. Overall, 104 patients were excluded because they did not meet the inclusion criteria . Five of the final 23 patients invited, refused to participate in the study.
