Causes Of Parkinson’s Disease
Parkinson’s disease is caused by a loss of nerve cells in part of the brain called the substantia nigra. This leads to a reduction in a chemical called dopamine in the brain.
Dopamine plays a vital role in regulating the movement of the body. A reduction in dopamine is responsible for many of the symptoms of Parkinson’s disease.
Exactly what causes the loss of nerve cells is unclear. Most experts think that a combination of genetic and environmental factors is responsible.
Depression May Be An Early Symptom Of Parkinsons
Depression is one of the most common, and most disabling, non-motor symptoms of Parkinsons disease. As many as 50 per cent of people with Parkinsons experience the symptoms of clinical depression at some stage of the disease. Some people experience depression up to a decade or more before experiencing any motor symptoms of Parkinsons.
Clinical depression and anxiety are underdiagnosed symptoms of Parkinsons. Researchers believe that depression and anxiety in Parkinsons disease may be due to chemical and physical changes in the area of the brain that affect mood as well as movement. These changes are caused by the disease itself.
Here are some suggestions to help identify depression in Parkinsons:
- Mention changes in mood to your physician if they do not ask you about these conditions.
- Complete our Geriatric Depression Scale-15 to record your feelings so you can discuss symptoms with your doctor. Download the answer key and compare your responses.
- delusions and impulse control disorders
Embarrassing Symptoms Of Parkinson’s Disease
Some symptoms that may occur in people with Parkinsons disease are not typical of it and so people noticing them may misunderstand them. These symptoms can be particularly embarrassing in social situations where other people witness their discomfort. They distress some people so much that they avoid company other than close friends or family. Most of these symptoms are caused by Parkinsons but some are side effects of the medicines used to treat it. All the symptoms tend to fluctuate in relation to the medication, and some people had learnt to adjust their medicine regime to minimise these effects.
Eating can cause embarrassment in several ways. Both tremor and dyskinesia affect the physical job of cutting up food and directing it into the mouth . Several people had a problem with a piece of steak or chicken that might fly off the plate as they tried to cut it up, or they had a choking fit if they unwisely took too big a piece into their mouth. Humphrey disliked eating out with friends because he tended to drop things.

Elimination Of Other Conditions
Although no test can diagnose Parkinson’s disease itself, your doctor may order blood tests or imaging studies to rule out other causes of your symptoms.
Your doctor will want to know about any medication or recreational drugs you take, since some drugs can cause symptoms similar to those of Parkinson’s.
Doctors sometimes order dopamine transporter SPECT imaging to determine whether a person with suspected Parkinson’s has a different disorder called essential tremor.
What Are The Symptoms Of Parkinsons Disease
Symptoms of Parkinsons disease and the rate of decline vary widely from person to person. The most common symptoms include:
Other symptoms include:
- Speech/vocal changes: Speech may be quick, become slurred or be soft in tone. You may hesitate before speaking. The pitch of your voice may become unchanged .
- Handwriting changes: You handwriting may become smaller and more difficult to read.
- Depression and anxiety.
- Sleeping disturbances including disrupted sleep, acting out your dreams, and restless leg syndrome.
- Pain, lack of interest , fatigue, change in weight, vision changes.
- Low blood pressure.

Symptoms Of Parkinson’s Disease
The symptoms of Parkinson’s disease usually develop gradually and are mild at first.
There are many different symptoms associated with Parkinson’s disease. Some of the more common symptoms are described below.
However, the order in which these develop and their severity is different for each individual. It’s unlikely that a person with Parkinson’s disease would experience all or most of these.
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

Can A Stroke Cause Parkinson’s Disease
A stroke can cause some symptoms of Parkinson’s disease, but not Parkinson’s disease itself. This condition is called Parkinsonism. Parkinsonism is associated with many of the same movement problems of Parkinson’s disease, such as tremors and stiffness. However, it usually does not worsen over time as Parkinson’s disease does. If a stroke causes brain damage in the area of the brain that is associated with Parkinson’s disease, then Parkinsonism can occur.
How Is Parkinson’s Disease Managed
Your doctors will tailor your treatment based on your individual circumstances. You will manage your condition best if you have the support of a team, which may include a general practitioner, neurologist, physiotherapist, occupational therapist, psychologist, specialist nurse and dietitian.
While there is no cure for Parkinson’s disease, symptoms can be treated with a combination of the following.
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 .
What Is Parkinson’s Disease
Parkinsons disease occurs when brain cells that make dopamine, a chemical that coordinates movement, stop working or die. Because PD can cause tremor, slowness, stiffness, and walking and balance problems, it is called a movement disorder. But constipation, depression, memory problems and other non-movement symptoms also can be part of Parkinsons. PD is a lifelong and progressive disease, which means that symptoms slowly worsen over time.
The experience of living with Parkinson’s over the course of a lifetime is unique to each person. As symptoms and progression vary from person to person, neither you nor your doctor can predict which symptoms you will get, when you will get them or how severe they will be. Even though broad paths of similarity are observed among individuals with PD as the disease progresses, there is no guarantee you will experience what you see in others.
Parkinsons affects nearly 1 million people in the United States and more than 6 million people worldwide.

What Are The Non
While Parkinson’s disease is often associated with movement changes, there are a variety of non-motor symptoms, as well. Non-motor symptoms refer to the many other changes to a person’s health and wellbeing that can happen from Parkinson’s.
These symptoms can sometimes have an even greater impact on a person’s life than tremor, rigidity, and slow movement, so it’s important to keep an eye out for them in someone with the disorder. Here are some of the non-motor symptoms of Parkinson’s disease to look out for:
What Are The Symptoms Of Parkinson’s Disease
The main symptoms of Parkinson’s disease are:
- tremor or shaking, often when resting or tired. It usually begins in one arm or hand
- muscle rigidity or stiffness, which can limit movement and may be painful
- slowing of movement, which may lead to periods of freezing and small shuffling steps
- stooped posture and balance problems
The symptoms of Parkinson’s disease vary from person to person as well as over time. Some people also experience:
- loss of unconscious movements, such as blinking and smiling
- difficulties with handwriting
- drop in blood pressure leading to dizziness
- difficulty swallowing
Many of the symptoms of Parkinson’s disease could be caused by other conditions. For example, stooped posture could be caused by osteoporosis. But if you are worried by your symptoms, it is a good idea to see your doctor.
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.
How Is A Diagnosis Made
Because other conditions and medications mimic the symptoms of PD, getting an accurate diagnosis from a physician is important. No single test can confirm a diagnosis of PD, because the symptoms vary from person to person. A thorough history and physical exam should be enough for a diagnosis to be made. Other conditions that have Parkinsons-like symptoms include Parkinsons plus, essential tremor, progressive supranuclear palsy, multi-system atrophy, dystonia, and normal pressure hydrocephalus.

Stiffness And Slow Movement
Parkinsons disease mainly affects adults older than 60. You may feel stiff and a little slow to get going in the morning at this stage of your life. This is a completely normal development in many healthy people. The difference with PD is that the stiffness and slowness it causes dont go away as you get up and start your day.
Stiffness of the limbs and slow movement appear early on with PD. These symptoms are caused by the impairment of the neurons that control movement. A person with PD will notice jerkier motions and move in a more uncoordinated pattern than before. Eventually, a person may develop the characteristic shuffling gait.
Diagnosis And Management Of Parkinsons Disease
There are no diagnostic tests for Parkinsons. X-rays, scans and blood tests may be used to rule out other conditions. For this reason, getting a diagnosis of Parkinsons may take some time.
No two people with Parkinsons disease will have exactly the same symptoms or treatment. Your doctor or neurologist can help you decide which treatments to use.
People can manage their Parkinsons disease symptoms through:
- seeing a Doctor who specialises in Parkinsons
- multidisciplinary therapy provided for example, by nurses, allied health professionals and counsellors
- deep brain stimulation surgery .

What Can You Do If You Have Pd
- Work with your doctor to create a plan to stay healthy. This might include the following:
- A referral to a neurologist, a doctor who specializes in the brain
- Care from an occupational therapist, physical therapist or speech therapist
- Meeting with a medical social worker to talk about how Parkinson’s will affect your life

The mask that is the expressionless face, typical of many people with Parkinsons, probably distresses the people who have to live with it more than it embarrasses the person who has it. It tends to be the position the face falls into when not actively doing something else. Lack of facial expression can be hard for the family.

The 5 Stages Of Parkinsons Disease
Getting older is underrated by most. Its a joyful experience to sit back, relax and watch the people in your life grow up, have kids of their own and flourish. Age can be a beautiful thing, even as our bodies begin to slow down. We spoke with David Shprecher, DO, movement disorders director at Banner Sun Health Research Institute about a well-known illness which afflicts as many as 2% of people older than 65, Parkinsons Disease.
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.

Brain Imaging And Other Tools To Aid Diagnosis Of Parkinsons
In addition to taking a history and performing a detailed neurologic examination, physicians sometimes use brain imaging to help support a particular diagnosis. However, these studies have their limitations in the diagnosis of Parkinsons disease and are typically used only in select patients. Brain imaging is not routinely performed by neurologists or movement disorder specialists when they are considering a diagnosis, especially if the persons symptoms strongly suggest to the physician that idiopathic Parkinsons disease is the correct diagnosis.
Helping diagnose Parkinsons with DaTscan and other tests
Rather, use of imaging is most helpful when the diagnosis is uncertain, or when physicians are looking for changes in the brain that are more typical of one of several Parkinsonian syndromes and other conditions that can mimic Parkinsons. Imaging studies to evaluate Parkinsons disease and Parkinsonian syndromes include magnetic resonance imaging , which examines the structure of the brain, and DaTscan, an imaging test approved by the Food and Drug Administration to detect the dopamine function in the brain. A DaTscan may help differentiate idiopathic Parkinsons disease from certain other neurologic disorders. Most physicians offices will have access to MRI however, DaTscan imaging may only be available at larger hospitals or medical centers.
Support For People With Parkinsons Disease
Early access to a multidisciplinary support team is important. These teams may include doctors, physiotherapists, occupational therapists, speech therapists, dietitians, social workers and specialist nurses. Members of the team assess the person with Parkinsons disease and identify potential difficulties and possible solutions.There are a limited number of multidisciplinary teams in Victoria that specialise in Parkinsons disease management. But generalist teams are becoming more aware of how to help people with Parkinsons disease.

Deep Brain Stimulation For Parkinson’s: Am I A Candidate
Deep brain stimulation is not a cure, but it can relieve your symptoms from Parkinson’s disease when medications are not an option. Only you and your doctor can decide if this surgical procedure is right for you. You may be a candidate for deep brain stimulation if:
- You have idiopathic Parkinson’s disease. Patients with atypical parkinsonism are not candidates.
- You have good motor function and independence during your best “on” state when taking the drug Sinemet.
How Is Parkinson’s Disease Diagnosed
A person doesn’t need to have all the signs and symptoms of Parkinson’s disease to be diagnosed with it.
“In general, people have a combination of the motor symptoms and the non-motor symptoms,” says Dr. Nwabuobi. “Some people have more non-motor symptoms than motor and vice versa, but in order to have a diagnosis of Parkinson’s, you definitely need the motor symptoms. We’re looking for specific things , including a rest tremor, bradykinesia, rigidity, and poor balance.”
According to the Parkinson’s Foundation, a person needs to have two of the four main motor symptoms of Parkinson’s over a period of time to be diagnosed with the disease.
