What Causes Parkinson’s Syndrome

Complementary And Alternative Therapies

What causes Parkinson’s disease?

Some people with Parkinson’s disease find complementary therapies help them feel better. Many complementary treatments and therapies claim to ease the symptoms of Parkinson’s disease.

However, there’s no clinical evidence they’re effective in controlling the symptoms of Parkinson’s disease.

Most people think complementary treatments have no harmful effects. However, some can be harmful and they shouldn’t be used instead of the medicines prescribed by your doctor.

Some types of herbal remedies, such as St John’s wort, can interact unpredictably if taken with some types of medication used to treat Parkinson’s disease.

If you’re considering using an alternative treatment along with your prescribed medicines, check with your care team first.

What Are The Symptoms

PSP affects movement, control of walking and balance, speech, swallowing, eye movements and vision, mood and behavior, and thinking. The pattern of signs and symptoms can be quite different from person to person. The most frequent first symptom of PSP is a loss of balance while walking. Individuals may have abrupt and unexplained falls without loss of consciousness, a stiff and awkward gait, or slow movement.

As the disease progresses, most people will begin to develop a blurring of vision and problems controlling eye movement. These symptoms may include:

  • Slow eye movements.

Medications For People With Parkinsons Disease

Symptoms of Parkinsons disease result from the progressive degeneration of nerve cells in the brain and other organs such as the gut, which produce a neurotransmitter called dopamine. This causes a deficiency in the availability of dopamine, which is necessary for smooth and controlled movements. Medication therapy focuses on maximising the availability of dopamine in the brain. Medication regimes are individually tailored to your specific need. Parkinsons medications fit into one of the following broad categories:

  • levodopa dopamine replacement therapy
  • dopamine agonists mimic the action of dopamine
  • COMT inhibitors used along with levodopa. This medication blocks an enzyme known as COMT to prevent levodopa breaking down in the intestine, allowing more of it to reach the brain
  • anticholinergics block the effect of another brain chemical to rebalance its levels with dopamine
  • amantadine has anticholinergic properties and improves dopamine transmission
  • MAO type B inhibitors prevent the metabolism of dopamine within the brain.

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.

The Nervous System & Dopamine

To understand Parkinson’s, it is helpful to understand how neurons work and how PD affects the brain .

Nerve cells, or neurons, are responsible for sending and receiving nerve impulses or messages between the body and the brain. Try to picture electrical wiring in your home. An electrical circuit is made up of numerous wires connected in such a way that when a light switch is turned on, a light bulb will beam. Similarly, a neuron that is excited will transmit its energy to neurons that are next to it.

Neurons have a cell body with branching arms, called dendrites, which act like antennae and pick up messages. Axons carry messages away from the cell body. Impulses travel from neuron to neuron, from the axon of one cell to the dendrites of another, by crossing over a tiny gap between the two nerve cells called a synapse. Chemical messengers called neurotransmitters allow the electrical impulse to cross the gap.

Neurons talk to each other in the following manner :

Other Causes Of Parkinsonism

“Parkinsonism” is the umbrella term used to describe the symptoms of tremors, muscle rigidity and slowness of movement.

Parkinson’s disease is the most common type of parkinsonism, but there are also some rarer types where a specific cause can be identified.

These include parkinsonism caused by:

  • medication where symptoms develop after taking certain medications, such as some types of antipsychotic medication, and usually improve once the medication is stopped
  • other progressive brain conditions such as progressive supranuclear palsy, multiple systems atrophy and corticobasal degeneration
  • cerebrovascular disease where a series of small strokes cause several parts of the brain to die

You can read more about parkinsonism on the Parkinson’s UK website.

What Are The Different Stages Of Parkinsons Disease

Each person with Parkinsons disease experiences symptoms in in their own unique way. Not everyone experiences all symptoms of Parkinsons disease. You may not experience symptoms in the same order as others. Some people may have mild symptoms others may have intense symptoms. How quickly symptoms worsen also varies from individual to individual and is difficult to impossible to predict at the outset.

In general, the disease progresses from early stage to mid-stage to mid-late-stage to advanced stage. This is what typically occurs during each of these stages:

Early stage

Early symptoms of Parkinsons disease are usually mild and typically occur slowly and do not interfere with daily activities. Sometimes early symptoms are not easy to detect or you may think early symptoms are simply normal signs of aging. You may have fatigue or a general sense of uneasiness. You may feel a slight tremor or have difficulty standing.

Often, a family member or friend notices some of the subtle signs before you do. They may notice things like body stiffness or lack of normal movement slow or small handwriting, lack of expression in your face, or difficulty getting out of a chair.

Mid stage

Mid-late stage

Standing and walking are becoming more difficult and may require assistance with a walker. You may need full time help to continue to live at home.

Advanced stage

Don’t Miss: What Is The Life Expectancy Of Someone With Parkinson’s Disease

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 Surgical Treatments For Parkinsons Disease

What Causes Parkinson’s Disease?

Most patients with Parkinsons disease can maintain a good quality of life with medications. However, as the disease worsens, medications may no longer be effective in some patients. In these patients, the effectiveness of medications becomes unpredictable reducing symptoms during on periods and no longer controlling symptoms during off periods, which usually occur when the medication is wearing off and just before the next dose is to be taken. Sometimes these variations can be managed with changes in medications. However, sometimes they cant. Based on the type and severity of your symptoms, the failure of adjustments in your medications, the decline in your quality of life and your overall health, your doctor may discuss some of the available surgical options.

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.

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.

Can Drug Induced Parkinsonism Be Prevented

Although there is no surety in the prevention of drug-induced parkinsons disease, but efforts may be made to check the dosage of drugs so prescribed-

Be Cautious with Antipsychotics: The patient or in some cases the caregiver should make sure that antipsychotic drugs are given at their least effective dosage.

Inform the Doctor: The doctor should be informed well before in case the patient already has symptoms of Parkinsons disease so that they do not appear to get worse with the starting of some prescribed drugs.

Abrupt Stoppage of Medicine: It is never a wise decision to stop taking a medicine by oneself. It is important to talk to the doctor in case of any concerns.

What Are The Causes

What Are The Best Essential Oils And Recipes To Manage ...

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 Treatments Are Available

Many Parkinson’s patients enjoy an active lifestyle and a normal life expectancy. Maintaining a healthy lifestyle by eating a balanced diet and staying physically active contributes to overall health and well-being. Parkinson’s disease can be managed with self-care, medication, and surgery.

Self careExercise is as important as medication in the treatment of PD. It helps maintain flexibility and improves balance and range of motion. Patients may want to join a support group and continue enjoyable activities to improve their quality of life. Equally important is the health and well being of the family and caregivers who are also coping with PD. For additional pointers, see Coping With Parkinsons Disease.

These are some practical tips patients can use:

Medications There are several types of medications used to manage Parkinson’s. These medications may be used alone or in combination with each other, depending if your symptoms are mild or advanced.

After a time on medication, patients may notice that each dose wears off before the next dose can be taken or erratic fluctuations in dose effect . Anti-Parkinsons drugs can cause dyskinesia, which are involuntary jerking or swaying movements that typically occur at peak dosage and are caused by an overload of dopamine medication. Sometimes dyskinesia can be more troublesome than the Parkinsons symptoms.

Mapping The Future Of Parkinsons Disease

PD GENEration: Mapping the Future of Parkinsons Disease is a Parkinsons Foundation initiative that offers genetic testing and genetic counseling at no cost for people with Parkinsons disease . When you participate, you can help scientists in their journey to advance understanding of PD, leading to new, more effective PD therapies.

Parkinsons disease has four main symptoms:

  • Tremor in hands, arms, legs, jaw, or head
  • Stiffness of the limbs and trunk
  • Slowness of movement
  • Impaired balance and coordination, sometimes leading to falls

Other symptoms may include depression and other emotional changes difficulty swallowing, chewing, and speaking urinary problems or constipationskin problems and sleep disruptions.

Symptoms of Parkinsons and the rate of progression differ among individuals. Sometimes people dismiss early symptoms of Parkinsons as the effects of normal aging. In most cases, there are no medical tests to definitively detect the disease, so it can be difficult to diagnose accurately.

Early symptoms of Parkinsons disease are subtle and occur gradually. For example, affected 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.

Tremors Caused By Medications

In addition to drug-induced parkinsonism, which includes rest tremor and is caused by medications that block the dopamine receptor, there are also a wide variety of medications that do not block the dopamine receptor, but can cause other types of tremors, such as postural and action tremors. So if you have these types of tremors, but without the slowness, stiffness and other PD-like symptoms, you could have drug-induced tremor .

A postural tremor occurs when a body part is held against gravity. Postural tremors occur for example, when the arms are extended, such as when holding a tray. An action tremor occurs when a body part is moving. Action tremors occur for example, when the arm is moving toward the mouth to eat.

Drug-induced tremors typically are symmetric or equal on both sides of the body. The medications that can cause tremor include, but are not limited to, lithium, valproic acid, amiodarone, beta-adrenergic agonists, and selective serotonin reuptake inhibitors . Be attentive to whether a tremor starts after any new medication is started. If it does, discuss this with your doctor.

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

Treatments And Outcomes Of Dip

DIP is generally treated by cessation of the offending drugs. Patients who cannot stop taking antipsychotic drugs because of their psychiatric diseases, such as those with schizophrenia or major depressive disorders, may be switched to atypical antipsychotics that have a lower risk of EPS. People who are prescribed dopamine antagonists due to simple GI disturbance, headache, dizziness, or insomnia should stop taking the offending drugs as soon as possible. Anticholinergics including trihexyphenidyl, benztropine, amantadine, and levodopa have been empirically tested for their ability to relieve symptoms of DIP, but this has produced no clear evidence of their effects in DIP patients.,,,,

What Is The Difference Between Drug Induced Parkinsons Disease And Typically Occurring Parkinsons Disease

Understanding the Brain: Final Project

It has been seen that drug-induced Parkinsonism usually occur on both sides of your body while usual Parkinsons starts from one side of the body. Apart from this, the medication-induced signs generally are seen to go away after the medicine is finished. However, it may take few months to stop, but is does stop eventually. On the contrary, the typically occurring Parkinsons disease cannot be reversed. Another thing to be kept in mind is that medication-induced Parkinsons disease is not progressive, unlike the typical Parkinsons disease.
