Is Parkinson’s Disease A Motor Neuron Disease

Parkinsons Disease Vs Als Differences In Symptoms Causes And Treatment

Parkinsons disease and ALS can cause difficulties in movement and are both known to be progressive neurological diseases.

ALS is part of a cluster of disorders known as motor neuron diseases that involve gradual degeneration and death of motor neurons. In a healthy individual, messages from motor neurons in the brain are transmitted to the motor neurons in the spinal cord and sent to the particular muscles. In ALS, this communication degenerates and cells begin to die. As a result, the message that is transmitted is incomplete. Unable to function, the muscles begin to weaken and waste away over time. Eventually, communication from the brain to muscles is lost completely.

In its early stage, ALS also known as Lou Gehrigs disease may appear as Parkinsons disease, which is also a neurological disease similar to ALS. Here we will outline the causes, symptoms, and treatment options for both ALS and Parkinsons disease to help you understand the differences between the two.

These diseases both affect your nerves. MS can break down the coating, called myelin, that surrounds and protects your nerves. In Parkinson’s, nerve cells in a part of your brain slowly die off. Both can start out with mild symptoms, but they get worse over time.

Furthermore, is Parkinson disease and upper motor neuron lesion? Rigidity of the muscles on passive movement is characteristic of Parkinson’s disease but must be distinguished from the rigidity resulting from upper motor neuron lesions, for example, in patients with a stroke. Additionally, patients with Parkinson’s disease may show a cogwheel type of rigidity.

Similarly, is Lou Gehrig’s disease the same as Parkinson’s?

Parkinson’s disease is a movement disorder that afflicts over one million in the U.S.; amyotrophic lateral sclerosis is less prevalent but also has a high incidence. The two disorders sometimes present together, making a comparative study of interest.

Who gets motor neurone disease?

The condition can affect adults of all ages, including teenagers, although this is extremely rare. It’s usually diagnosed in people over 40, but most people with the condition first develop symptoms in their 60s. It affects slightly more men than women.

What Is The Prognosis And Life Expectancy For Parkinsons Disease

The severity of Parkinsons disease symptoms and signs vary greatly from person to peson, and it is not possible to predict how quickly the disease will progress. Parkinsons disease itself is not a fatal disease, and the average life expectancy is similar to that of people without the disease. Secondary complications, such as , falling-related injuries, and choking can lead to death. Many treatment options can reduce some of the symptoms and prolong the quality of life.

No One Definitive Cause Of Parkinsons


There are no biomarkers or objective screening tests that indicate one has Parkinsons. That said, medical experts have shown that a constellation of factors are linked to it.

Parkinsons causes are likely a blend of genetics and environmental or other unknown factors. About 10 to 20 percent of Parkinsons disease cases are linked to a genetic cause, says Ted Dawson, M.D., Ph.D., director of the Institute for Cell Engineering at Johns Hopkins. The types are either autosomal dominant or autosomal recessive .

But that leaves the majority of Parkinsons cases as idiopathic, which means unknown. We think its probably a combination of environmental exposure to toxins or pesticides and your genetic makeup, says Dawson.

Age. The biggest risk factor for developing Parkinsons is advancing age. The average age of onset is 60.

Gender. Men are more likely to develop Parkinsons disease than women.

Genetics. Individuals with a parent or sibling who is affected have approximately two times the chance of developing Parkinsons. Theres been an enormous amount of new information about genetics and new genes identified over the past 10 or 15 years that have opened up a greater understanding of the disease, says Dawson.

Make Sure You Get Enough Vitamin D And Omega

Vitamin D deficiency is associated with an increased risk of Parkinsons disease, whereas vitamin D supplementation and sunlight exposure are associated with a reduced risk. How does vitamin D combat neurodegeneration in Parkinsons disease? A high density of vitamin D receptors reside in the part of the brain most affected by Parkinsons disease; this finding suggests that vitamin D regulates the function of neurons.

Vitamin D also lessens the severity of autoimmunity and regulates neurotrophins, proteins that induce the survival, development, and function of neurons. Vitamin D is one nutrient you wont want to skimp on if your goal is to prevent Parkinsons disease!Safe sun exposure is the best method for boosting vitamin D levels. However, full-body sun exposure is not possible for most people year-round; in this case, I recommend you take cod liver oil and eat fatty cold-water fish, beef liver, and egg yolks to obtain dietary vitamin D.

Omega-3 fatty acids, like EPA and DHA, are critical for normal brain development and function across the lifespan. Low levels of EPA and DHA increase the risk of neurodegeneration, whereas omega-3 supplementation can help reduce neuron death in the brain, alleviate neuroinflammation, boost antioxidant enzymes, and relieve motor symptoms in PD. EPA and DHA are abundant in seafood, so I recommend consuming two to three servings of seafood per week to achieve a healthy intake of these neuroprotective fatty acids.

Who Is At Risk

MNDs occur in both adults and children. In children, MNDs are typically due to specific gene mutations, as in spinal muscular atrophy. Symptoms can be present at birth or appear in early childhood. In adults, MNDs are more likely to be sporadic, meaning the disease occurs with no family history. Symptoms typically appear after age 50, though onset of disease may occur at any age.

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.

Incidence And Prevalence: Als Compared With Parkinsons

All neurodegenerative diseases are conditions where there is an impact on the brain and/or the central nervous system.

According to statistics, ALS currently affects around 30,000 people in the USA, with around 6,000 new cases being identified each year.

Parkinsons Disease affects around a million people in America and there are about 60,000 new cases annually.

Famous individuals affected by Parkinsons include Michael J Fox and Scottish comedian Billy Connelly. In terms of ALS, the late Professor Stephen Hawking was one prominent public figure who had been diagnosed with a form of ALS. The late legendary US baseball player Lou Gehrig was also diagnosed with ALS and subsequently the condition has been commonly referred to as Lou Gehrigs disease ever since.

Parkinsons is perhaps a much more well known condition, due to its increased prevalence throughout the world, however ALS has received a lot more attention and awareness since the Ice Bucket Challenge which went viral on social media during the summer of 2014.

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. NINDS is a component of the National Institutes of Health , the leading supporter of biomedical research in the world.

supports a broad range of research aimed at discovering the cause of MNDs, finding better treatments, and, ultimately, preventing and curing the disorders. Various animal and cellular models are being used to study disease pathology and identify chemical and molecular processes involved with MNDs.

Research is focused on creating new and better medicines and identifying genetic mutations and other factors that may influence the development of these diseases.

Drug interventions

Researchers are testing whether different drugs, agents, or interventions are safe and effective in slowing the progression of MNDs.

SMA occurs when individuals do not have enough SMN protein. supported researchers are testing drug-like compounds that increase SMN levels to determine if any of them offer potential benefits for treating the disease. If these experiments are successful, researchers will begin testing these compounds in human clinical trials.

Other compounds and medications, including minocycline, ceftriaxone, dexpramipexole, coenzyme Q10, and lithium, have been tested but were not effective in treating MNDs.

Gene therapy

How Are Motor Neuron Diseases Treated


There is no cure or standard treatment for MNDs. Symptomatic and supportive treatment can help people affected by these diseases be more comfortable while maintaining their quality of life.

Multidisciplinary clinics, with specialists from neurology, physical therapy, respiratory therapy, and social work are particularly important in the care of individuals with MNDs.


Supportive therapies

  • Physical therapy and rehabilitation. These therapies may help improve posture, prevent joint immobility, and slow muscle weakness and atrophy. Stretching and strengthening exercises may help reduce stiffness, as well as increase range of motion and circulation. Some individuals require additional therapy for speech, chewing, and swallowing difficulties. Applying heat may relieve muscle pain. Assistive devices such as supports or braces, orthotics, speech synthesizers, and wheelchairs may help some people maintain independence.
  • Proper nutrition and a balanced diet. These things are essential to maintaining weight and strength. People who cannot chew or swallow may require a feeding tube.
  • Ventilators. Non-invasive positive pressure ventilation at night can prevent sleep apnea. Some individuals may also require assisted ventilation during the day due to muscle weakness in the neck, throat, and chest.

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 :

Black Americans And Parkinsons Disease

Most research suggests that Parkinsons disease is more likely to affect whites and Hispanics.

But, some studies have shown that Black patients may be less likely to receive proper care for the disease. 

A review published in 2018 in  found there are racial disparities when it comes to managing Parkinsons disease.

Researchers identified one study that showed Black patients were 4 times less likely than whites to be started on treatment for Parkinsons.

Another study found an average seven-year delay in diagnosis among Black patients.

Stage One Of Parkinsons Disease

In stage one, the earliest stage, the symptoms of PD are mild and only seen on one side of the body , and there is usually minimal or no functional impairment.

The symptoms of PD at stage one may be so mild that the person doesnt seek medical attention or the physician is unable to make a . Symptoms at stage one may include , such as intermittent tremor of one hand, , or one hand or leg may feel more clumsy than another, or one side of the face may be affected, impacting the expression.

This stage is very difficult to diagnose and a physician may wait to see if the symptoms get worse over time before making a formal diagnosis.

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.

Muscle Cramps And Stiffness

Medications, such as botulinum toxin injections. blocks the signals from the brain to the stiff muscles for about 3 months.

Baclofen, a muscle relaxer, may help relieve muscle stiffness, spasms, and yawning. A doctor can surgically implant a small pump outside the body to deliver regular doses to the space around the spinal cord, from where it can reach the nervous system.

Some people may find physical therapy helps alleviate cramps and stiffness.

What Causes Parkinsons Disease

Parkinsons disease occurs when nerve cells, or neurons, in an area of the brain that controls movement become impaired and/or die. Normally, these neurons produce an important brain chemical known as dopamine. When the neurons die or become impaired, they produce less dopamine, which causes the movement problems of Parkinsons. Scientists still do not know what causes cells that produce dopamine to die.

People with Parkinsons also lose the nerve endings that produce norepinephrine, the main chemical messenger of the sympathetic nervous system, which controls many functions of the body, such as heart rate and blood pressure. The loss of norepinephrine might help explain some of the non-movement features of Parkinsons, such as , irregular blood pressure, decreased movement of food through the digestive tract, and sudden drop in blood pressure when a person stands up from a sitting or lying-down position.

Many brain cells of people with Parkinsons contain Lewy bodies, unusual clumps of the protein alpha-synuclein. Scientists are trying to better understand the normal and abnormal functions of alpha-synuclein and its relationship to genetic mutations that impact Parkinsons disease and Lewy body dementia.

Treatment Of Prion Disorders

The problem with prion disorders is a similar problem to cancer. A pathological process has been switched on which then has a momentum of its own. Stopping the smoker from smoking does not cure his lung cancer! However one should be able to slow down the progression of the disease hopefully to an extent where healing and repair exceeds damage. There has to be a reason why Stephen Hawking has survived motor neurone disease for 30 years when for most the prognosis is much worse!

1. Identify the initiator – identify toxic exposures and detox. See Chemical poisons and toxins. Deal with these specifically – see Detoxification – an overview and Detoxing – Far Infrared Sauna . Heavy metals are commonly implicated and the best test for these is to measure urinary toxic metals following DMSA challange . ]

3. Because there is an element of autoimmunity in prion disorders, tackle Autoimmune diseases – the environmental approach to treating

4. Anything to reduce inflammation is likely to be helpful See especially high dose vitamin D. Tests of antioxidant status are important ]

How Will Parkinsons Disease Affect Your Life

130 best images about Neuroanatomy on Pinterest

Finding out that you have a long-term, progressive disease can lead to a wide range of feelings. You may feel angry, afraid, sad, or worried about what lies ahead. It may help to keep a few things in mind:

  • Usually this disease progresses slowly. Some people live for many years with only minor symptoms.
  • Many people are able to keep working for years. As the disease gets worse, you may need to change how you work.
  • It is important to take an active role in your health care. Find a doctor you trust and can work with.
  • Depression is common in people who have Parkinsons. If you feel very sad or hopeless, talk to your doctor or see a counselor.
  • It can make a big difference to know that youre not alone. Ask your doctor about Parkinsons support groups, or look for online groups or message boards.
  • Parkinsons affects more than just the person who has it. It also affects your loved ones. Be sure to include them in your decisions.

Als Vs Parkinsons Disease: Symptoms

ALS is a neurodegenerative disease that affects the neurons in the body. It usually starts as a localized issue in an area like the hands or legs. A person diagnosed with ALS will often feel weakness in a certain part of the body. The disease destroys the neurons and begins to spread throughout the whole body causing damage elsewhere.

Parkinsons disease is also a neurodegenerative disorder but it actually affects a particular part of the brain rather than all neurons. It specifically attacks parts of the brain called the basal ganglia and the substantia nigra. Early symptoms may include difficulty sleeping and loss of sense of smell rather than loss of motor movement.

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 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 .

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.


Is Huntington’s Disease A Motor Neuron Disease

4.3/5motor neuron diseaseHuntington diseasemotor neuron disease

Huntington’s disease and amyotrophic lateral sclerosis are both relentlessly progressive neurodegenerative disorders for which diagnostic and predictive gene testing have been available for ~20 years. HD is a single gene autosomal dominant disorder whereas ALS is highly heterogeneous and complex.

Beside above, who gets motor neurone disease? The condition can affect adults of all ages, including teenagers, although this is extremely rare. It’s usually diagnosed in people over 40, but most people with the condition first develop symptoms in their 60s. It affects slightly more men than women.

Correspondingly, what are first signs of motor neuron disease?

Symptoms of motor neurone disease

  • muscle aches, cramps, twitching.
  • weakness or changes in hands, arms, legs and voice.
  • slurred speech, swallowing or chewing difficulty.
  • fatigue.

What Is Parkinson’s Disease

Parkinsons disease is a degenerative, progressive disorder that affects nerve cells in deep parts of the brain called the basal ganglia and the substantia nigra. Nerve cells in the substantia nigra produce the neurotransmitter dopamine and are responsible for relaying messages that plan and control body movement. For reasons not yet understood, the dopamine-producing nerve cells of the substantia nigra begin to die off in some individuals. When 80 percent of dopamine is lost, PD symptoms such as tremor, slowness of movement, stiffness, and balance problems occur.

Body movement is controlled by a complex chain of decisions involving inter-connected groups of nerve cells called ganglia. Information comes to a central area of the brain called the striatum, which works with the substantia nigra to send impulses back and forth from the spinal cord to the brain. The basal ganglia and cerebellum are responsible for ensuring that movement is carried out in a smooth, fluid manner .

The action of dopamine is opposed by another neurotransmitter called acetylcholine. In PD the nerve cells that produce dopamine are dying. The PD symptoms of tremor and stiffness occur when the nerve cells fire and there isn’t enough dopamine to transmit messages. High levels of glutamate, another neurotransmitter, also appear in PD as the body tries to compensate for the lack of dopamine.

In Summary Reduce Your Stress

The most important thing we can do for our long-term health, both physical and cognitive, is to reduce the stress in our bodies. All stress physical, emotional and chemical causes inflammation and long-term damage throughout the body.

Whether youre seeking Parkinsons prevention techniques or ways to alleviate symptoms, any of the above dietary and lifestyle practices can have long-term health benefits. Drinking green tea, eating organic, local vegetables, and regular aerobic exercise all significantly reduce the long-term cumulative damage done by stress.
