Parkinsons disease is an illness that affects the part of your brain that controls how you move your body, MuscleHowever, Larger numbers of people with PD have relatedParkinsons disease is a progressive disorder of the brain and is the most common type of Parkinsonism, A deficiency in vitamin D can lead to complications, even if the future seems bleak, In the later stages of the disease, Progressive supranuclear palsy 3.Parkinsons disease belongs to a group of conditions called motor system disorders, a person with Parkinsons may have a fixed or blank expression, But over time, 2019, Causes, Nearly every person who lives with PD will experience some degree of muscle rigidity, due to a combination of abnormal protein accumulation in cells, Surveys show that between 20% and 40% of people with Parkinsons disease suffer from serious constipation
What Does Parkinson’s Do To The Brain
Deep down in your brain, there’s an area called the substantia nigra, which is in the basal ganglia. Some of its cells make dopamine, a chemical that carries messages around your brain. When you need to scratch an itch or kick a ball, dopamine quickly carries a message to the nerve cell that controls that movement.
When that system is working well, your body moves smoothly and evenly. But when you have Parkinson’s, the cells of your substantia nigra start to die. There’s no replacing them, so your dopamine levels drop and you can’t fire off as many messages to control smooth body movements.
Early on, you won’t notice anything different. But as more and more cells die, you reach a tipping point where you start to have symptoms.
That may not be until 80% of the cells are gone, which is why you can have Parkinson’s for quite a while before you realize it.

Surgery For People With Parkinsons Disease
Deep brain stimulation surgery is an option to treat Parkinsons disease symptoms, but it is not suitable for everyone. There are strict criteria and guidelines on who can be a candidate for surgery, and this is something that only your doctor and you can decide. Surgery may be considered early or late in the progression of Parkinsons.;When performing deep-brain stimulation surgery, the surgeon places an electrode in the part of the brain most effected by Parkinsons disease. Electrical impulses are introduced to the brain, which has the effect of normalising the brains electrical activity reducing the symptoms of Parkinsons disease. The electrical impulse is introduced using a pacemaker-like device called a stimulator.;Thalamotomy and pallidotomy are operations where the surgeon makes an incision on part of the brain. These surgeries aim to alleviate some forms of tremor or unusual movement, but they are rarely performed now.
Parkinsons Tremor: Effects On The Body
Parkinsons disease causes damage to the nerves in the brain, causing a reduction of dopamine cells and an accumulation of alpha-synuclein also known as Lewy bodies. This damage is what causes the motor symptoms of Parkinsons disease, such as tremors and Parkinsons disease gait.
Despite what many people think, the Parkinson’s tremor isn’t the most challenging symptom of Parkinson’s disease. For many, tremors are irritating or uncomfortable, but they aren’t debilitating. There is evidence to suggest that those who experience tremor as a major symptom have milder versions of the disease and live longer, though no one knows quite why this happens.

What Are The Treatments For Parkinson’s Disease
There is no cure for PD, and no treatment prevents the disease from progressing. However, treatments can usually ease symptoms.
- At first, you may not need any treatment when the symptoms are mild. A specialist may simply see you every now and then to monitor how the disease is progressing.
- A medicine that eases symptoms is usually started when symptoms become troublesome.
- Therapies such as physiotherapy, occupational therapy and speech therapy may also be useful as the disease progresses.
- Surgery may be an option for severe cases.
Parkinsons Disease Effects On The Body Tremor Motor Symptoms
The Parkinson’s tremor affects 80% of people with Parkinson’s disease. Sadly, it is also one of the more difficult symptoms to treat. The PD tremor is characterized by a quivering movement or shakes that occurs at rest, but it presents differently in everyone. People in the early stages of PD usually experience tremors starting in one hand, leg or foot, but the tremor may eventually progress to both sides of the body. Find out the effects of Parkinson’s tremor on the body and explore ways to treat motor symptoms of the disease.

What Research Is Being Done
The mission of the National Institute of Neurological Disorders and Stroke is to seek fundamental knowledge about the brain and nervous system and to use that knowledge to reduce the burden of neurological disease. ;The NINDS is a component of the National Institutes of Health , the leading supporter of biomedical research in the world.
Researchers are working to better understand the underlying brain functions that cause tremor, identify the genetic factors that make individuals more susceptible to the disorder, and develop new and better treatment options.
Brain functioningIt can be difficult to distinguish between movement disorders such as Parkinson’s disease and essential tremor. These debilitating movement disorders have different prognoses and can respond very differently to available therapies. NINDS researchers are working to identify structural and functional changes in the brain using non-invasive neuroimaging techniques to develop sensitive and specific markers for each of these diseases and then track how they change as each disease progresses.
Other researchers are using functional magnetic resonance imaging technology to better understand normal and diseased brain circuit functions and associated motor behaviors. ;Scientists hope to design therapies that can restore normal brain circuit function in diseases such as Parkinson’s disease and tremor.
Medications and other treatment methods
What Are The Different Categories Or Types Of Tremor
Tremor is most commonly classified by its appearance and cause or origin. ;There are more than 20 types of tremor. ;Some of the most common forms of tremor include:
Essential tremor is one of the most common movement disorders. ;The exact cause of essential tremor is unknown. ;For some people this tremor is mild and remains stable for many years. ;The tremor usually appears on both sides of the body, but is often noticed more in the dominant hand because it is an action tremor.
The key feature of essential tremor is a tremor in both hands and arms, which is present during action and when standing still. ;Additional symptoms may include head tremor without abnormal posturing of the head and a shaking or quivering sound to the voice if the tremor affects the voice box. ;The action tremor in both hands in essential tremor can lead to problems with writing, drawing, drinking from a cup, or using tools or a computer.
Tremor frequency may decrease as the person ages, but the severity may increase, affecting the persons ability to perform certain tasks or activities of daily living. ;Heightened emotion, stress, fever, physical exhaustion, or low blood sugar may trigger tremor and/or increase its severity. ;Though the tremor can start at any age, it most often appears for the first time during adolescence or in middle age . ;Small amounts of alcohol may help decrease essential tremor, but the mechanism behind this is unknown.

How Is Parkinsons Disease Diagnosed
Diagnosing Parkinsons disease is sometimes difficult, since early symptoms can mimic other disorders and there are no specific blood or other laboratory tests to diagnose the disease. Imaging tests, such as CT or MRI scans, may be used to rule out other disorders that cause similar symptoms.
To diagnose Parkinsons disease, you will be asked about your medical history and family history of neurologic disorders as well as your current symptoms, medications and possible exposure to toxins. Your doctor will look for signs of tremor and muscle rigidity, watch you walk, check your posture and coordination and look for slowness of movement.
If you think you may have Parkinsons disease, you should probably see a neurologist, preferably a movement disorders-trained neurologist. The treatment decisions made early in the illness can affect the long-term success of the treatment.
The Spread Of Parkinsons
Researchers have found that areas of the brain stem below the substantia nigra show cell loss in Parkinsons. And cells in these areas have been found to contain clumps of alpha-synuclein protein, which may form before those in the substantia nigra.
These findings have led some researchers to suggest that Parkinsons spreads up the spinal cord to the substantia nigra. Indeed, there is evidence that, for some, Parkinsons may start in the gut and travel up the vagus nerve, which connects the gut and the brain, to the substantia nigra.
The theory that Parkinsons may spread up the brain stem and progress throughout the brain is the basis of the Braak staging of Parkinsons.
The 6 stages in Braaks theory aim to describe the spread of Parkinsons through the brain:
While there is still some debate over the origin of Parkinsons, and even competing and more complex theories about the spread of Parkinsons, attempts to understand how and why different areas of the brain are involved in the motor and non-motor symptoms are helping in the development of better treatments.

How Does Parkinsons Disease Affect The Body
Recognising the signs
A combination of signs can help a doctor make an early diagnosis. If Parkinsons disease is diagnosed early, the chances of being able to treat and manage the condition are greater.;Individual signs may not be an indication of Parkinsons disease.;Some signs such as loss of smell could be caused by an infectious illness, or;joint stiffness by conditions like arthritis.
Parkinsons is most commonly diagnosed with a very;physical examination;and assessment of a persons;medical history. There are very specific markers for diagnosis which doctors use to assess for possible Parkinsons disease. These markers have a lot to do with a combination of very specific signs and symptoms and if recognised early enough, can be better managed.
1. Primary motor symptoms
2. Secondary motor symptoms
Other motor symptoms include:
Some individuals may also experience the following:
- Hunched over / stooped posture – When standing, the body may begin to slouch or lean inwards, causing a hunched over appearance.
- Impaired gross motor coordination
- Impaired fine motor dexterity and motor coordination
- Difficulties with swallowing or chewing
- Production of excess saliva and drooling
- Sexual dysfunction
3. Non-motor symptoms
Symptoms that do not involve physical movement or coordination, and often precede motor problems, can include:
Symptoms are initially mild, even if they develop suddenly, and typically affect one side of the body at first.
How Is Tremor Classified
Tremor can be classified into two main categories:
Resting tremor occurs when the muscle is relaxed, such as when the hands are resting on the lap. ;With this disorder, a persons hands, arms, or legs may shake even when they are at rest. ;Often, the tremor only affects the hand or fingers. ;This type of tremor is often seen in people with Parkinsons disease and is called a pillrolling tremor because the circular finger and hand movements resemble rolling of small objects or pills in the hand.;;
Action tremor occurs with the voluntary movement of a muscle. Most types of tremor are considered action tremor. ;There are several sub-classifications of action tremor, many of which overlap.
- Postural tremor occurs when a person maintains a position against gravity, such as holding the arms outstretched.
- Kinetic tremor is associated with any voluntary movement, such as moving the wrists up and down or closing and opening the eyes.
- Intention tremor is produced with purposeful movement toward a target, such as lifting a finger to touch the nose. ;Typically the tremor will become worse as an individual gets closer to their target.
- Task-specific tremor only appears when performing highly-skilled, goal-oriented tasks such as handwriting or speaking.
- Isometric tremor occurs during a voluntary muscle contraction that is not accompanied by any movement such as holding a heavy book or a dumbbell in the same position.

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.
Treatment For The Motor Symptoms Of Parkinson’s Disease
There are many ways to deal with Parkinsons disease motor symptoms, including medications, occupational therapy and lifestyle adjustments. You may find that tremors make you more susceptible to accidents such as tripping, falling or spilling hot liquids so you must take care and ask for the help and support you need.
Unlike other Parkinson’s motor symptoms, tremors can be hard to treat with medication. However, medicines can be helpful for treating symptoms such as Parkinson’s disease gait impairments, which can have a major impact on your life. The gait of Parkinson’s disease presents slightly differently in each patient. Some experience the Parkinson’s disease shuffling gate, which can make movement markedly slower and make it look like you are “dragging your feet.” You may also experience reduced arm movement while walking.
In Parkinson’s disease, freezing of gait is characterized by hesitation before stepping forward, or a feeling like your feet have frozen to the floor. Frozen gait usually only lasts for a step or two, but you will need to be careful when crossing busy streets and try to minimize your risk of falling wherever possible.
You can talk to your doctor about medications to try, as well your surgical and homeopathic options. However, there is no cure for Parkinson’s disease and no way to stop the symptoms entirely, but scientists are working to change that.

How Is Parkinsons Disease Currently Treated
Since many of the major features of PD are caused by the loss of neurons that release dopamine, treatment focuses on replacing dopamine or imitating its effects with drugs that mimic its actions that have produced great clinical benefit since the 1960s. However, over time these drugs create significant side effects of their own, including erratic motor responses and involuntary movements as well as neuropsychiatric problems. Thus, these drugs, which need to be consistently taken, create problems that ultimately may be as problematic as the disease they are being used to treat.
For later, more advanced stages of the disease, invasive deep brain surgical stimulation may also be used, but is not without risks, and, like the pharmaceutical options, may offer only temporary symptomatic relief.
How Is Parkinson Disease Diagnosed
Parkinson disease can be hard to diagnose. No single test can identify it. Parkinson can be easily mistaken for another health condition. A healthcare provider will usually take a medical history, including a family history to find out if anyone else in your family has Parkinson’s disease. He or she will also do a neurological exam. Sometimes, an MRI or CT scan, or some other imaging scan of the brain can identify other problems or rule out other diseases.

How Parkinson’s Affects The Nervous System
It has long been understood that Parkinson’s disease does not just cause movement symptoms, but also causes a litany of non-motor symptoms with effects throughout the body. One of the organ systems that is affected is the cardiac system, encompassing the heart, as well as the major and minor blood vessels.
Secondly, what are the changes to the brain caused by Parkinson’s disease? The brain changes caused by Parkinson’s disease begin in a region that plays a key role in movement, leading to early symptoms that include tremors and shakiness, muscle stiffness, a shuffling step, stooped posture, difficulty initiating movement and lack of facial expression.
Similarly one may ask, does Parkinson’s affect your spine?
Low back pain and back of the neck pain are probably the most common pain conditions in PD. The reason Parkinson’s Disease patients have so many problems with their low back and their neck is their posture. Because of the stooped posture, the muscles in the lower back have to pull much harder to keep the spine upright.
Does stress cause Parkinson’s?
Research suggests that stressful life events may increase the risk of Parkinson’s disease. In addition, animal studies indicate that stress damages dopamine cells, resulting in more severe parkinsonian symptoms. In humans, acute stress can worsen motor symptoms, including bradykinesia, freezing, and tremor.
