What Is Parkinsons Disease
Parkinsons disease is a nervous system disease that affects your ability to control movement. The disease usually starts out slowly and worsens over time. If you have Parkinsons disease, you may shake, have muscle stiffness, and have trouble walking and maintaining your balance and coordination. As the disease worsens, you may have trouble talking, sleeping, have mental and memory problems, experience behavioral changes and have other symptoms.
What Are The Symptoms
Symptoms of PD vary from person to person, as does the rate of progression. A person who has Parkinson’s may experience some of these more common “hallmark” symptoms:
- Bradykinesia – slowness of movement, impaired dexterity, decreased blinking, drooling, expressionless face.
- Tremor at rest – involuntary shaking that decreases with purposeful movement. Typically starts on one side of the body, usually the hand.
- Rigidity – stiffness caused by involuntary increase in muscle tone.
- Postural instability – sense of imbalance. Patients often compensate by lowering their center of gravity, which results in a stooped posture.
Other symptoms that may or may not occur:
Freezing or being stuck in place Shuffling gait or dragging of one foot Stooped posture Cognitive impairment
Do Animals Suffer From Parkinsons Disease
PD is one of many human diseases which do not appear to have spontaneously arisen in animals. The characteristic features of the disease can however be more or less faithfully imitated in animals through the administration of various neurotoxic agents and drugs disturbing the dopaminergic neurotransmission.

Symptoms That May Be Related To Pd But That Few People Know About
People with PD and care partners may suspect that a particular symptom is related to PD, but they cant find information about it, so they are not sure. Two symptoms that pop up in this category are runny nose and breathing problems, which well focus on today. Of course, if these are new symptoms for you, they could be indicative of a new problem, including infection with COVID-19, so make sure to get yourself checked out by your doctor. However, if all else is ruled out, PD could be to blame. Excessive sweating and specific skin disorders are in this category as well and have been addressed previously.
Exercise And Healthy Eating
Regular exercise is particularly important in helping relieve muscle stiffness, improving your mood, and relieving stress.
There are many activities you can do to help keep yourself fit, ranging from more active sports like tennis and cycling, to less strenuous activities such as walking, gardening and yoga.
You should also try to eat a balanced diet containing all the food groups to give your body the nutrition it needs to stay healthy.

Research And Statistics: Who Has Parkinsons Disease
According to the Parkinsons Foundation, nearly 1 million people in the United States are living with the disease. More than 10 million people worldwide have Parkinsons.
About 4 percent of people with Parkinsons are diagnosed before age 50.
Men are 1.5 times more likely to develop the disease than women.

Physical Issues Of Your Sex Drive
Parkinsons affects ones autonomic nervous system, which controls sexual response and functioning. Parkinsons acts upon neurons in the brains substantia nigra, causing dopamine-producing nerve cells to die. Since dopamine is a chemical that transmits signals between parts of the brain that usually coordinate smooth muscle movement, this is critical to sexual function on two fronts.

First, this dopamine drop may result in a decreased sex drive and sexual interest. Second, the lower levels of dopamine that result are believed to cause ones loss of balance, changes in walking pattern and posture, muscle rigidity, Bradykinesia , and tremors when resting.

How Quickly Does Parkinsons Disease Develop
In most cases, symptoms change slowly, with substantive progression taking place over the space of many months or years. Many people with PD have symptoms for at least a year or two before a diagnosis is actually made. The longer symptoms are present, the easier it is to predict how a person with PD will do over time.

Environmental Factors And Exposures
Exposure to pesticides and a history of head injury have each been linked with PD, but the risks are modest. Never having smoked cigarettes, and never drinking caffeinated beverages, are also associated with small increases in risk of developing PD.
Low concentrations of urate in the blood is associated with an increased risk of PD.
Drug-induced parkinsonism
Different medical drugs have been implicated in cases of parkinsonism. Drug-induced parkinsonism is normally reversible by stopping the offending agent. Drugs include:
What Is Wrong With Conventional Surgery
The use of multi-level open surgery in Parkinsons Syndrome Sufferers including microdiscectomy, decompression, solid or flexible fusion and is an overkill with negative side-effects including blood loss, potential nerve and tissue damage, extended post-operative care and unnecessarily operating on pain-free levels is fraught with aggravation of the current symptom status. It is not as effective as Foraminoplasty in addressing and ameliorating the effects of Parkinsons Syndrome Sufferers, rather it runs the risk of increased neurological complications as well as causing the complications of recurrent disc bulging, infection, nerve damage and scarring round the nerve, implant failure, major vessel damage or sexual dysfunction.

What Are The Causes
The cause of Parkinson’s is largely unknown. Scientists are currently investigating the role that genetics, environmental factors, and the natural process of aging have on cell death and PD.
There are also secondary forms of PD that are caused by medications such as haloperidol , reserpine , and metoclopramide .
Medicines For Parkinson’s Disease
Medicines prescribed for Parkinson’s include:
- Drugs that increase the level of dopamine in the brain
- Drugs that affect other brain chemicals in the body
- Drugs that help control nonmotor symptoms
The main therapy for Parkinson’s is levodopa, also called L-dopa. Nerve cells use levodopa to make dopamine to replenish the brain’s dwindling supply. Usually, people take levodopa along with another medication called carbidopa. Carbidopa prevents or reduces some of the side effects of levodopa therapysuch as nausea, vomiting, low blood pressure, and restlessnessand reduces the amount of levodopa needed to improve symptoms.
People with Parkinson’s should never stop taking levodopa without telling their doctor. Suddenly stopping the drug may have serious side effects, such as being unable to move or having difficulty breathing.
Other medicines used to treat Parkinsons symptoms include:
- Dopamine agonists to mimic the role of dopamine in the brain
- MAO-B inhibitors to slow down an enzyme that breaks down dopamine in the brain
- COMT inhibitors to help break down dopamine
- Amantadine, an old antiviral drug, to reduce involuntary movements
- Anticholinergic drugs to reduce tremors and muscle rigidity

What Causes Parkinson Disease
Parkinson disease arises from decreased dopamine production in the brain. The absence of dopamine makes it hard for the brain to coordinate muscle movements. Low dopamine also contributes to mood and cognitive problems later in the course of the disease. Experts don’t know what triggers the development of Parkinson disease most of the time. Early onset Parkinson disease is often inherited and is the result of certain gene defects.
Be Honest With Yourself And Your Doctor
It is important to discuss alcohol consumption with your doctor to make sure you are approaching it safely. Elements of PD, including motor symptoms such as bradykinesia and dyskinesia , will vary from person to person, so its important to make decisions based on your medical history.
Taking into account environmental factors such as how central alcohol is to your social life can affect the decisions you make. Be honest with your doctor about your habits and preferences remember, your doctor wants to work with you to make your symptoms as manageable as possible, not to judge or shame you.
As you decide how alcohol may fit into your life post-diagnosis lifestyle, there are many factors to consider, such as the type of alcoholic beverage, your other risk factors, and your neurologists recommendations specific to your medical history. Most importantly, monitor how you feel when you drink alcohol and be willing to have open and honest conversations about drinking with your doctor and other important people in your life.
I am not even a big drinker, but miss the odd one, wrote a MyParkinsonsTeam member. So, I had an alcohol-free beer, which tasted OK, to be honest.

How Does Alcohol Affect Parkinsons Medication
The interaction between Parkinsons medications and alcohol is a common topic on MyParkinsonsTeam. I miss my red wine and whiskey on occasion, one member wrote. I found that it just makes my meds stop working. Another member said, My husband has been told he shouldn’t drink with his meds.
Alcohol can exacerbate the side effects of one of the most common Parkinsons medications, levodopa/carbidopa. Many neurologists recommend avoiding alcohol while taking this drug.
I have to limit myself to one Scotch on the rocks now, a MyParkinsonsTeam member said. I used to have three or four, but the side effects are too bad. Another wrote, Never really a good idea to mix alcohol with meds.
Whether you decide to continue your current drinking habits, cut down, or eliminate alcohol altogether, its important to listen to your body and have open conversations about these topics with your neurologist.
If you find yourself drinking alcohol to cope with other issues, such as depression and anxiety, you may find that healthy practices such as physical activity can help. In addition, participating in activities such as tai chi, yoga, and meditation may help ease the symptoms and complications of PD.
Eat Fresh Raw Vegetables
If you needed more reasons to eat your vegetables, this should be the clincher. Studies show that increased amounts of the B vitamin folic acid, found primarily in vegetables, can significantly reduce the risk of Parkinsons.
The best sources of folic acid are simultaneously some of the healthiest foods on the planet, namely dark green vegetables like broccoli, spinach, collard greens, brussels sprouts, asparagus and okra all of which can be grown in your backyard! This B vitamin can also be found in avocado, legumes and lentils.

Parkinson ‘s Disease Is A Progressive Loss Of Functioning Of The Brain
Introduction:Parkinsons disease is a progressive loss of functioning of the brain that results in stiffness, trembling and loss of fine motor control. This disease mainly affects the neurons in the particular area called the substantia nigra with a total loss of dopamine, the absence of these dopamine-producing cells causes the loss of the brains ability to control the body movements progressively . Parkinsons disease is very common, with about 70000 Australians as
Symptoms That Are Commonly Associated With Pd
These symptoms include sleep disorders, abnormalities in blood pressure, urinary problems, constipation, depression, and anxiety. Even though these symptoms are so commonly seen in PD, they are also commonly associated with other issues that have nothing to do with PD, so it is vital to keep an open mind about their cause. If any symptom is new or worsening, it could be an indication of a new medical problem. For example, urinary problems are extremely common in PD, but may be a sign of an enlarged prostate, which can be treated in an entirely different way.

What Causes Parkinsons Disease
Parkinsons disease occurs when nerve cells in an area of the brain called the substantia nigra become impaired or die. These cells normally produce dopamine, a chemical that helps the cells of the brain communicate . When these nerve cells become impaired or die, they produce less dopamine. Dopamine is especially important for the operation of another area of the brain called the basal ganglia. This area of the brain is responsible for organizing the brains commands for body movement. The loss of dopamine causes the movement symptoms seen in people with Parkinsons disease.
People with Parkinsons disease also lose another neurotransmitter called norepinephrine. This chemical is needed for proper functioning of the sympathetic nervous system. This system controls some of the bodys autonomic functions such as digestion, heart rate, blood pressure and breathing. Loss of norepinephrine causes some of the non-movement-related symptoms of Parkinsons disease.
Scientists arent sure what causes the neurons that produce these neurotransmitter chemicals to die.
Causes Of Parkinsons Disease
At present, we do not know the cause of Parkinsons disease. In most people there is no family history of Parkinsons Researchers worldwide are investigating possible causes, including:
- environmental triggers, pesticides, toxins, chemicals
- genetic factors
- combinations of environment and genetic factors
- head trauma.

Signs Of Parkinsons Disease
In 1817, Dr. James Parkinson published An Essay on the Shaking Palsy describing non-motor, as well as, motor symptoms of the illness that bears his name. Parkinsons is not just a movement disorder, explained Dr. Shprecher. Constipation, impaired sense of smell, and dream enactment can occur years before motor symptoms of Parkinsons. The latter, caused by a condition called REM sleep behavior disorder, is a very strong risk factor for both Parkinsons and dementia . This has prompted us to join a consortium of centers studying REM sleep behavior disorder.
Causes And Risk Factors Of Parkinsons Disease
Most cases of Parkinsons disease are idiopathic, meaning the cause is unclear.
Its widely believed that a person with Parkinsons may have been genetically vulnerable to the disease, and that one or more unknown factors in the environment eventually triggered the disease.
Most of the symptoms of Parkinsons disease come from the loss of neurons in an area of your brain called the substantia nigra.
Normally, the neurons in this part of the brain make the chemical messenger dopamine, which allows communication with another area of the brain, the corpus striatum.
This communication helps produce smooth, purposeful movement. When the neurons in the substantia nigra die, the resulting loss of communication leads to the motor symptoms of Parkinsons.
Although the cause of this cell death is unknown, many researchers believe that the cells are killed by clumped proteins called Lewy bodies.

Living With Parkinsons Disease
Depending on severity, life can look very different for a person coping with Parkinsons Disease. As a loved one, your top priority will be their comfort, peace of mind and safety. Dr. Shprecher offered some advice, regardless of the diseases progression. Besides movement issues Parkinsons Disease can cause a wide variety of symptoms including drooling, constipation, low blood pressure when standing up, voice problems, depression, anxiety, sleep problems, hallucinations and dementia. Therefore, regular visits with a neurologist experienced with Parkinsons are important to make sure the diagnosis is on target, and the symptoms are monitored and addressed. Because changes in your other medications can affect your Parkinsons symptoms, you should remind each member of your healthcare team to send a copy of your clinic note after every appointment.
Dr. Shprecher also added that maintaining a healthy diet and getting regular exercise can help improve quality of life. Physical and speech therapists are welcome additions to any caregiving team.
Can The Sources Of Pain Be Pinpointed
Aware state surgical examination enables the patient to give the surgeon feedback, guiding him or her to the point that is responsible for the pain. This live approach allows the causal level in Parkinsons Syndrome Sufferers to be accurately defined and then viewed using endoscopic instruments through a tiny incision. In this way, neural anomalies and strange nerve combinations can be detected and diagnostic errors regarding the disc level responsible for the pain, avoided. Thus, the surgeon is guided to the precise source of pain at that specified inter-vertebral point and the understanding of the actual mechanisms underlying the causation of Parkinsons Syndrome Sufferers.

Motor Circuit In Parkinson Disease
The basal ganglia motor circuit modulates the cortical output necessary for normal movement .
Signals from the cerebral cortex are processed through the basal ganglia-thalamocortical motor circuit and return to the same area via a feedback pathway. Output from the motor circuit is directed through the internal segment of the globus pallidus and the substantia nigra pars reticulata . This inhibitory output is directed to the thalamocortical pathway and suppresses movement.
Two pathways exist within the basal ganglia circuit, the direct and indirect pathways, as follows:
-
In the direct pathway, outflow from the striatum directly inhibits the GPi and SNr striatal neurons containing D1 receptors constitute the direct pathway and project to the GPi/SNr
-
The indirect pathway contains inhibitory connections between the striatum and the external segment of the globus pallidus and between the GPe and the subthalamic nucleus striatal neurons with D2 receptors are part of the indirect pathway and project to the GPe
The STN exerts an excitatory influence on the GPi and SNr. The GPi/SNr sends inhibitory output to the ventral lateral nucleus of the thalamus. Dopamine is released from nigrostriatal neurons to activate the direct pathway and inhibit the indirect pathway. In Parkinson disease, decreased striatal dopamine causes increased inhibitory output from the GPi/SNr via both the direct and indirect pathways .
