What Happens With Parkinson’s

Can Imaging Tests Diagnose Lewy Body Dementia

Imaging tests, such as computed tomography or magnetic resonance imaging , are done to rule out other causes of dementia such as brain tumors, brain bleeds, stroke, hydrocephalus or other structural causes. Imaging studies for Lewy body dementia are usually normal. The only way to make an absolute diagnosis of LBD is by examining the brain at autopsy.

What Is Parkinson Disease

Parkinson disease is a movement disorder. It can cause the muscles to tighten and become rigid This makes it hard to walk and do other daily activities. People with Parkinsons disease also have tremors and may develop cognitive problems, including memory loss and dementia.

Parkinson disease is most common in people who are older than 50. The average age at which it occurs is 60. But some younger people may also get Parkinson disease. When it affects someone younger than age 50, it’s called early-onset Parkinson disease. You may be more likely to get early-onset Parkinson disease if someone in your family has it. The older you are, the greater your risk of developing Parkinson disease. It’s also much more common in men than in women.

Parkinson disease is a chronic and progressive disease. It doesn’t go away and continues to get worse over time.

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.

Diagnosis Of Parkinsons Disease

A number of disorders can cause symptoms similar to those of Parkinson’s disease. People with Parkinson’s-like symptoms that result from other causes are sometimes said to have parkinsonism. While these disorders initially may be misdiagnosed as Parkinson’s, certain medical tests, as well as response to drug treatment, may help to distinguish them from Parkinson’s. Since many other diseases have similar features but require different treatments, it is important to make an exact diagnosis as soon as possible.

There are currently no blood or laboratory tests to diagnose nongenetic cases of Parkinson’s disease. Diagnosis is based on a person’s medical history and a neurological examination. Improvement after initiating medication is another important hallmark of Parkinson’s disease.

How Is Parkinson’s Disease Treated

If a doctor thinks a person has Parkinson’s disease, there’s reason for hope. Medicine can be used to eliminate or improve the symptoms, like the body tremors. And some experts think that a cure may be found soon.

For now, a medicine called levodopa is often given to people who have Parkinson’s disease. Called “L-dopa,” this medicine increases the amount of dopamine in the body and has been shown to improve a person’s ability to walk and move around. Other drugs also help decrease and manage the symptoms by affecting dopamine levels. In some cases, surgery may be needed to treat it. The person would get anesthesia, a special kind of medicine to prevent pain during the operation.

What Is Parkinsonism Is It Different From Parkinsons

Parkinsons disease is the most common cause of parkinsonism, a category of neurological diseases that cause slowed movement.

No quick or easy diagnostic tests exist for Parkinsons disease, so a patient may receive an initial diagnosis of parkinsonism without a more specific condition being confirmed.

Classic Parkinsons disease referred to as idiopathic because it has no known cause is the most common and most treatable parkinsonism.

About 15 percent of people with parkinsonism have atypical variants, which are also known as Parkinsons plus syndromes.

What Are The Risk Factors For Parkinsons Disease

Risk factors for Parkinsons disease include:

Genetics

People with a first-degree relative with Parkinsons are at an increased risk for the disease possibly as much as 9 percent greater.

Fifteen to 25 percent of people with Parkinsons have a known relative with the disease, but a condition called familial Parkinsons, which has a known genetic link, is relatively rare.

The average age of onset is 60 years, and the incidence rises with advancing age. About 10 percent of people have early-onset or young-onset disease, which begins before age 50.

Gender

Parkinsons affects about 50 percent more men than women, for unknown reasons.

Pesticide Exposure

Exposure to some pesticides has been shown to raise the risk of developing Parkinsons.

Problematic chemicals include organochlorine pesticides like DDT, dieldrin, and chlordane. Rotenone and permethrin have also been implicated.

Fungicide and Herbicide Exposure

Exposure to the fungicide maneb or the herbicides 2,4-dichlorophenoxyacetic acid , paraquat, or Agent Orange may raise the risk of Parkinsons.

The U.S. Veterans Health Administration considers Parkinsons to be a possible service-related illness if the person was exposed to significant amounts of Agent Orange.

Head Injuries

Head injuries may contribute to the development of Parkinsons in some people.

Coffee and Smoking

People who drink coffee or smoke tobacco have been found to have a lower risk of Parkinsons disease, for reasons that remain unclear.

Symptoms Of Parkinsons Disease

Parkinson’s 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 constipation skin problems and sleep disruptions.

Symptoms of Parkinsons and the rate of progression differ among individuals. Sometimes people dismiss early symptoms of Parkinson’s 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 Parkinson’s 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 Parkinson’s. They may see that the person’s face lacks expression and animation, or that the person does not move an arm or leg normally.

People with Parkinson’s often develop a parkinsonian gait that includes a tendency to lean forward, small quick steps as if hurrying forward, and reduced swinging of the arms. They also may have trouble initiating or continuing movement.

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 Diagnosed

Doctors use your medical history and physical examination to diagnose Parkinson’s disease . No blood test, brain scan or other test can be used to make a definitive diagnosis of PD.

Researchers believe that in most people, Parkinson’s is caused by a combination of environmental and genetic factors. Certain environmental exposures, such as pesticides and head injury, are associated with an increased risk of PD. Still, most people have no clear exposure that doctors can point to as a straightforward cause. The same goes for genetics. Certain genetic mutations are linked to an increased risk of PD. But in the vast majority of people, Parkinsons is not directly related to a single genetic mutation. Learning more about the genetics of Parkinsons is one of our best chances to understand more about the disease and discover how to slow or stop its progression.

Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.

Men are diagnosed with Parkinsons at a higher rate than women and whites more than other races. Researchers are studying these disparities to understand more about the disease and health care access and to improve inclusivity across care and research.

Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.

The Michael J. Fox Foundation has made finding a test for Parkinsons disease one of our top priorities.

What Types Of Sleep Problems Do People With Parkinsons Disease Have

Parkinsons disease affects every person differently. It also impacts sleep in different ways. People with Parkinsons may have:

• Insomnia, finding it hard to fall asleep.
• Fragmented sleep, waking up many times over the night.
• Excessive daytime sleepiness, finding it hard to stay awake during the day.
• Very vivid dreams, which may cause hallucinations or confusion after waking up.
• Emotional dreams or nightmares, which may make you feel emotionally drained after waking up.

Living With Parkinson’s Disease

Coming to terms with a diagnosis of Parkinson’s and living with the disease is challenging and will take a lot of adjustment. There are still things you can do that can help you to feel more in control of your situation and to stay positive. Some things that might help could include:

• choosing to lead a healthy lifestyle
• making informed decisions related to your treatment
• keeping a diary of your symptoms in preparation for meetings with health and social care professionals
• attending a self-management course

Hospice Eligibility For Parkinsons Disease

Due to the progressive nature of Parkinsons disease, it can be challenging for families to know when their loved one is eligible for the support of hospice care. If a loved one has been diagnosed with six months or less to live or if they have experienced a decline in their ability to move, speak, or participate in the activities of daily living without caregiver assistance, it is time to speak with a hospice professional about next steps.

What Makes Pd Hard To Predict

Parkinsonâs comes with two main buckets of possible symptoms. One affects your ability to move and leads to motor issues like tremors and rigid muscles. The other bucket has non-motor symptoms, like pain, loss of smell, and dementia.

You may not get all the symptoms. And you canât predict how bad theyâll be, or how fast theyâll get worse. One person may have slight tremors but severe dementia. Another might have major tremors but no issues with thinking or memory. And someone else may have severe symptoms all around.

On top of that, the drugs that treat Parkinsonâs work better for some people than others. All that adds up to a disease thatâs very hard to predict.

How Do I Prevent Falls From Common Hazards

• Floors: Remove all loose wires, cords, and throw rugs. Minimize clutter. Make sure rugs are anchored and smooth. Keep furniture in its usual place.
• Bathroom: Install grab bars and non-skid tape in the tub or shower. Use non-skid bath mats on the floor or install wall-to-wall carpeting.
• Lighting: Make sure halls, stairways, and entrances are well-lit. Install a night light in your bathroom or hallway and staircase. Turn lights on if you get up in the middle of the night. Make sure lamps or light switches are within reach of the bed if you have to get up during the night.
• Kitchen: Install non-skid rubber mats near the sink and stove. Clean spills immediately.
• Stairs: Make sure treads, rails, and rugs are secure. Install a rail on both sides of the stairs. If stairs are a threat, it might be helpful to arrange most of your activities on the lower level to reduce the number of times you must climb the stairs.
• Entrances and doorways: Install metal handles on the walls adjacent to the doorknobs of all doors to make it more secure as you travel through the doorway.

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.

What Medications Are Used To Treat Parkinsons Disease

Medications are the main treatment method for patients with Parkinsons disease. Your doctor will work closely with you to develop a treatment plan best suited for you based on the severity of your disease at the time of diagnosis, side effects of the drug class and success or failure of symptom control of the medications you try.

Medications combat Parkinsons disease by:

• Helping nerve cells in the brain make dopamine.
• Mimicking the effects of dopamine in the brain.
• Blocking an enzyme that breaks down dopamine in the brain.
• Reducing some specific symptoms of Parkinsons disease.

Levodopa: Levodopa is a main treatment for the slowness of movement, tremor, and stiffness symptoms of Parkinsons disease. Nerve cells use levodopa to make dopamine, which replenishes the low amount found in the brain of persons with Parkinsons disease. Levodopa is usually taken with carbidopa to allow more levodopa to reach the brain and to prevent or reduce the nausea and vomiting, low blood pressure and other side effects of levodopa. Sinemet® is available in an immediate release formula and a long-acting, controlled release formula. Rytary® is a newer version of levodopa/carbidopa that is a longer-acting capsule. The newest addition is Inbrija®, which is inhaled levodopa. It is used by people already taking regular carbidopa/levodopa for when they have off episodes .

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.

What Can I Expect If I Or My Loved One Have A Diagnosis Of Lewy Body Dementia

Each persons experience with Lewy body dementia is unique to them. How slowly or quickly the disease progresses is impossible to know, but may be influenced by your general health and any existing diseases you may have. Because LBD is a progressive disease, difficulties with mind and body functions get worse over time. Currently, there is no known way to stop the progression of the disease. After diagnosis, most people with LBD live between five and seven years. Some people with LBD live up to 20 years after their diagnosis.

However, theres always hope. Research on LBD, dementia with lewy bodies, Alzheimers disease, Parkinsons disease with dementia are ongoing. New medications are being developed and new approaches to treatment are being investigated.

Symptoms Of Parkinson’s Disease

These common symptoms of Parkinson’s disease often begin gradually and progress over time:

• Shaking or tremor
• Poor posture
• Slowing of body movements

As the disease continues to progress, additional symptoms can occur such as slurred or soft speech, trouble chewing and/or swallowing, memory loss, constipation, trouble sleeping, loss of bladder control, anxiety, depression, inability to regulate body temperature, sexual dysfunction, decreased ability to smell, restless legs and muscle cramps.

How Parkinsons Disease Affects The Human Body

More than one million people live with Parkinsons disease in the U.S., but no two experiences are the same. Parkinsons affects individuals in vastly different ways: for some, Parkinsons may first show up as slight hand tremors, and in others, it might appear as an unusual level of stiffness. For one person it may progress slowly, and in someone else, it may spread frighteningly fast.

There are some consistencies in how the disease works, however, and understanding these similarities can help prepare for what to expect if you or a loved one is diagnosed with Parkinsons disease. From how it starts to how it progresses through its five stages, here are some of the ways Parkinsons affects the human body.
