Orthostatic Hypotension And Parkinsons: Could Sitting Up Be Affecting Your Memory
Orthostatic hypotension is among the most common non-motor symptoms in Parkinsons disease with prevalence reported as high as 53%. Yet, accurate diagnosis and management can often elude patients, who may be sent to a variety of specialists, including cardiology for management of fluctuations in blood pressure.
Both hypertension and hypotension contribute to cognitive decline, and a combination of vascular risk factors during an individuals lifetime could accelerate functional cognitive loss later in life.; According to some researchers, both elderly and younger individuals with orthostatic hypotension show relative deficits in verbal memory and sustained attention, both of which are predictors of subsequent cognitive decline that is greater than would be expected in the context of normal aging. Orthostatic hypotension, when it occurs in Parkinsons disease, is a sign of autonomic dysregulation. A better understanding of OH by patients and professionals treating Parkinsons patients is important as delayed treatment of fluctuating blood pressure can result in injuries from falls and also be associated with reversible cognitive decline.
Symptoms of OH include lightheadedness, fatigue, neck pain, presyncope, and syncope (syncope is a temporary loss of consciousness caused by a fall in blood pressure.

More Water And Salt: Simple Steps To Battle Low Blood Pressure
Increasing the amount of water you take can do wonders for your low blood pressure, especially if you were drinking too little initially. More salt in your diet is another pretty effective strategy as you’ll know, since you’ll have heard that people with high blood pressure need to stay away from sodium. Though salt will get your blood pressure up, don’t binge on salty foods without asking your doctor, as it can have other adverse effects, on your kidneys for instance.

Monitor Your Blood Pressure
You may find it useful to keep a diary of what triggers your symptoms and what makes them better or worse. This will help manage the problem.
If you have low blood pressure, you may need to tell the relevant driving authority, depending on what you drive.
At the time of printing, the government website states that you need to tell the DVLA in England Scotland and Wales or the DVA in Northern Ireland, if treatment for blood pressure causes side effects that could affect your ability to drive.
Please check with your relevant authority if you have problems with your blood pressure, as the rules may have recently changed.
Remember that you must contact your relevant driving licensing agency when you are diagnosed with Parkinsons.;

Understanding The Neurologic Control Of The Cardiac System
Before we explore this issue, lets first learn a bit about the autonomic nervous system and about the cardiac systems place within it. The ANS is part of the peripheral nervous system, a network of nerves throughout the body. The ANS exerts control over functions that are not under conscious direction such as respiration, heart function, blood pressure, digestion, urination, sexual function, pupillary response, and much more.; The ANS is further subdivided into the parasympathetic nervous system and the sympathetic nervous system. Both the parasympathetic and sympathetic nervous systems regulate most major organs. Often, they have opposite effects, with the sympathetic nervous system activating a system and the parasympathetic system calming it down.
One of the systems controlled by the ANS is cardiac regulation. Blood pressure sensors, known as baroreceptors, reside in the heart as well as in the carotid artery, the major artery in the neck. If the baroreceptors sense a change in the blood pressure, a signal is sent to particular areas in the brain. From there, the autonomic nervous system sends signals to the heart to control heart rate and cardiac output. Signals are also sent to the blood vessels to change the size of their diameter, thereby regulating blood pressure.
Low Blood Pressure In Parkinson’s Disease
This 2-page article discusses the frequency of orthostatic hypotension in those with PD, the cause, symptoms and several simple measures that can be used to restore normal blood pressure regulation, including medication evaluation, increase of fluids and salty foods, caffeine, frequent small meals, environment, clothing, slow position change, bed position and medication options.

How Parkinsons Disease Affects The Autonomic Nervous System And The Heart
In PD, there are two major reasons why the automatic control of the cardiac system is impaired. First, areas of the brain that control this system often contain Lewy bodies and have undergone neurodegeneration. In addition, the autonomic nervous system itself is directly affected by Lewy body-like accumulations and neurodegeneration. This means, when the baroreceptors in the heart and carotid artery sense a drop in blood pressure and try to generate a signal to the heart and blood vessels to increase the blood pressure, the message may not get through. This results in neurogenic orthostatic hypotension , or drops in blood pressure upon standing due to autonomic nervous system dysfunction. There are no medications that can cure nOH by restoring the autonomic nervous system in PD. nOH however, can be treated. Read more about nOH and its treatments here.
Structural problems of the heart such as coronary artery disease or cardiomyopathy are not thought to be part of the pathology of PD, although of course, could co-exist with PD.
Changes In Blood Pressure Cholesterol Levels May Predate Motor Symptoms In Parkinson Disease
Changes in blood pressure, percentage of red blood cells, and serum cholesterol levels were found to occur in patients with Parkinson disease before the onset of motor symptoms, suggesting potential biomarkers for early diagnosis and treatment.
Changes in blood pressure, percentage of red blood cells, and serum cholesterol levels were found to occur in patients with Parkinson disease before the onset of motor symptoms, according to study findings published in Scientific Reports.
PD, the second most common neurodegenerative disorder after Alzheimer disease, is a commonly misdiagnosed condition. In fact, a prior survey found that 21% of patients with PD had to see their general provider 3 times before being referred to a specialist.
As the studys accompanying press release notes, more than half of all dopaminergic neurons are already lost in PwP when motor symptoms like tremor and stiffness begin. Recent attempts to identify diagnostic biomarkers have indicated that some nonmotor symptoms, such as constipation and vision and eye issues, may predate the onset of motor symptoms in PD.
“If we can detect biological changes in the patients’ bodies well before the onset of the motor symptoms, we can start medical treatments in an early stage,” said Masahisa Katsuno, MD, professor in the Department of Neurology at the Nagoya University Graduate School of Medicine, in a statement.

Hypertension And Risk Of Subsequent Motor Pd
Seven cohort studies published between 2007 and 2015 included 3,170 persons who met the criteria for PD diagnosis and 339,517 participants who had not met the criteria for PD diagnosis during follow-up. Among them, four studies reported that hypertension is associated with an increased risk of PD , whereas the other three studies indicated that there was no significant association .

Can Parkinsons Disease Be Prevented
Unfortunately, no. Parkinsons disease is long-term disease that worsens over time. Although there is no way to prevent or cure the disease , medications may significantly relieve your symptoms. In some patients especially those with later-stage disease, surgery to improve symptoms may be an option.

What Is The Outlook For Persons With Parkinsons Disease
Although there is no cure or absolute evidence of ways to prevent Parkinsons disease, scientists are working hard to learn more about the disease and find innovative ways to better manage it, prevent it from progressing and ultimately curing it.
Currently, you and your healthcare teams efforts are focused on medical management of your symptoms along with general health and lifestyle improvement recommendations . By identifying individual symptoms and adjusting the course of action based on changes in symptoms, most people with Parkinsons disease can live fulfilling lives.
The future is hopeful. Some of the research underway includes:
- Using stem cells to produce new neurons, which would produce dopamine.
- Producing a dopamine-producing enzyme that is delivered to a gene in the brain that controls movement.
- Using a naturally occurring human protein glial cell-line derived neurotrophic factor, GDNF to protect dopamine-releasing nerve cells.
Many other investigations are underway too. Much has been learned, much progress has been made and additional discoveries are likely to come.
What Are The Primary Motor Symptoms Of Parkinsons Disease
There are four primary motor symptoms of Parkinsons disease: tremor, rigidity, bradykinesia and postural instability . Observing two or more of these symptoms is the main way that physicians diagnose Parkinsons.
It is important to know that not all of these symptoms must be present for a diagnosis of Parkinsons disease to be considered. In fact, younger people may only notice one or two of these motor symptoms, especially in the early stages of the disease. Not everyone with Parkinsons disease has a tremor, nor is a tremor proof of Parkinsons. If you suspect Parkinsons, see a neurologist or movement disorders specialist.

Parkinsons Disease And Low Blood Pressure Whats The Link
Low blood pressure is one of the most common non-motor signs of Parkinsons disease that affects one in 5 people with the disease . Although the problem can appear at any stage, people with mid and late-stage of Parkinsons disease are generally more affected.
For most patients, drop in the blood pressure happens early in the morning or after taking medication. For others, it can occur at any time of the day.
Research shows that lower blood pressure appears many years before the development of motor symptoms . Therefore, it is now being considered as one of the early warning signs of Parkinsons disease development.
Smaller Meals More Often
Postprandial “after meal” hypotension is more commonly associated with larger meals. If you have experienced this, try moving away from the more traditional three larger meals a day, and instead try six smaller meals. This approach can further help fight nausea, another problem that can strike as a side effect of Parkinson’s medications.

Underlying Causes Of Tachycardia You Must Know About
Ever felt your heart going too fast and wondered what was going on? When your heart starts beating too fast, at a rate of more than 100 beats per minute its known as tachycardia. So how does this happen? Your heart has two sides, a left side and a right side. And both sides have an upper chamber known as atrium which collects blood thats coming back to the heart and a lower chamber known as the ventricle which pumps blood away from the heart to other parts of the body. This pumping is regulated by an electrical current which starts in your sinoatrial node and spreads through your atria causing it to contract and squeeze blood into your ventricles. The electrical impulse then travels to the atrioventricular node which connects to your ventricles like a wire and sends the electrical signal to both of your ventricles simultaneously and causes them to contract.1 If these normal electrical pathways of your heart get disrupted then it can cause your heart to beat irregularly. Some people dont experience any symptoms when they have tachycardia. When symptoms are felt they can include palpitations, feeling dizzy or light headed, shortness of breath, fatigue, and chest pain.2 There are three main kinds of tachycardia classified according to the part of the heart where they originate ¬ atrial or supraventricular tachycardia, ventricular tachycardia, and sinus tachycardia. Lets take a look at some of the factors which can cause these abnormally fast heart rate:
How To Deal With Low Pressure In Parkinsons Disease
If you are a Parkinsons patient, it is very important to keep your eyes open on your blood pressure. Monitor and measure your blood pressure on regular bases, even if you dont feel any obvious signs. When taking blood pressure, do it in both seated and standing positions. It is good to take it 2-3 times a day. If you observed that your blood pressure is constantly low, talk to your caregiver immediately.
Here are some of the ways that can help you to maintain your blood pressure at a normal range.
- Drink a lot of water and avoid too much eating at once.
- If you have no issue with heart and kidney, increase the intake of salt in your food as it has been shown to elevate the blood pressure.
- Stop or reduce the consumption of alcohol and hot drinks. They widen the blood vessels and drop the blood pressure abruptly.
- Try to avoid excessive exercise as it can exacerbate the condition.
- Avoid changing your position suddenly. Take time to move from lying to sitting or from sitting to standing.
- Avoid standing for a long time.
- Consider the use of assistive devices like compression hose and an abdominal binder.

Stress Takes Its Toll In Parkinson’s Disease
- Date:
- Northwestern University
- Summary:
- A stressful lifestyle could lead to the premature death of a group of neurons, whose loss triggers the symptoms of Parkinson’s disease, according to a new study. Isradipine, a drug already approved for human use by the FDA, has been shown in preclinical studies to reduce the stress on these neurons and rejuvenate them. Scientists currently are conducting a clinical trial to find out if isradipine can be used safely and is tolerated by patients with Parkinson’s.
We all know that living a stressful lifestyle can take its toll, making us age faster and making us more susceptible to the cold going around the office.
The same appears to be true of neurons in the brain. According to a new Northwestern Medicine study published Nov. 10 in the journal Nature, dopamine-releasing neurons in a region of the brain called the substantia nigra lead a lifestyle that requires lots of energy, creating stress that could lead to the neurons’ premature death. Their death causes Parkinson’s disease.
The good news is preclinical research shows this stress can be controlled with a drug already approved for human use. By preventing calcium entry, the drug isradipine reduced the mitochondrial stress in dopamine-releasing neurons to the levels seen in neurons not affected by the disease.

Can Flomax Cause High Blood Pressure
Hello. This is Heart Health Tuesdays! Today, well talk about flomax and high blood pressure.;Flomax is an alph-blocker, or a special type of medication that blocks the alpha receptors in your body. These alpha blockers, and most notably Flomax, is used to treat men with an enlarged prostate gland, or benign prostatic hyperplasia . The effect is to reduce the problems that they have with urination. So can flomax cause high blood pressure?
Actually, Flomax can also be used in combination with other medications to treat hypertension when high blood pressure is difficult to control.
One of the side effects of using an alpha-blocker is that the blood pressure of the patient is often lowered slightly. This effect can be useful in patients who suffer not only from BPH but also from hypertension or high blood pressure. When Flomax is used in combination with other mild anti-hypertensive drugs the patient receives two benefits from their medication. They have relief from the BPH and their blood pressure comes under control.
Patients may ask their physician if Flomax causes high blood pressure but even the side effects of the medication are caused by lowering the blood pressure of the patient and not raising it accidentally.
Other side effects include abnormal ejaculation, back pain, cough, diarrhea, infections, runny nose, sore throat, and sinus problems.

What About High Blood Pressure
High blood pressure;is much more common in the general population than low blood pressure. It can lead to serious conditions such as;stroke;and heart attacks, but prompt treatment can avoid such complications.
Parkinsons does not cause high blood pressure, although people may have it as an unrelated condition. It can be effectively treated, but a careful balance has to be found so that low blood pressure does not result.
