Can Parkinsons Be Passed From Parent To Child
Its rare for Parkinsons disease to be passed down from parent to child. Most cases of Parkinsons arent hereditary. But people who get early-onset Parkinsons disease are more likely to have inherited it.
Having a family history of Parkinsons disease may increase the risk that youll get it. This means that having a parent or sibling with Parkinsons slightly increases the risk.
In most cases, the cause of Parkinsons disease remains unknown. But researchers have identified multiple risk factors that can increase your chances of getting this disease.
Risk factors for Parkinsons disease include:
- mutations in specific genes associated with Parkinsons
- having a family history of Parkinsons or a first-degree family member with Parkinsons
- being older, especially above the age of 60
- exposure to herbicides and pesticides
- being assigned male at birth
- history of brain injury
The Role Of Estrogen In Parkinsons Disease
PD affects multiple areas of the body and brain. One of the areas most clearly affected is the substantia nigra pars compacta. There is great damage and death of nerve cells in the substantia nigra. These cells make dopamine, a chemical messenger that carries the signal for the muscles to produce smooth, purposeful movements. Damage to the substania nigra causes the movements common to PD, such as tremor, rigidity, and loss of spontaneous movement.2
Estrogen has been shown to have multiple effects on dopamine, including the amount of dopamine absorbed into the nerve cells.7 Plus, estrogen appears to have a protective effect on the neurons that produce dopamine.8 Estrogens effects on dopamine change based on menstrual cycles, menopause, and hormone replacement therapies.
Researchers are interested in the possible use of estrogen to slow the progression of PD. However, the complexities of estrogen pose challenges in designing clinical studies.7 In addition, not all studies show that estrogen has a protective effect.3 However, larger scale, placebo-controlled studies are needed.
Parkinsons Strikes More Men Than Women Researchers Have Worked For Decades To Learn Why
J. William Langston, who has been studying and treating Parkinsons disease for nearly 40 years, always has found it striking that so many more men than women show up in his clinic. His observation is not anecdotal. It is grounded in science and shared by many physicians: Men are roughly 1.5 times more likely than women to develop Parkinsons, a progressive disorder of the nervous system that impairs movement and can erode mental acuity.
Its a big difference that is quite real, says Langston, clinical professor of neurology, neuroscience and of pathology at the Stanford University School of Medicine and associate director of the Stanford Udall Center. Its pretty dramatic. I think anyone who sees a lot of Parkinsons will tell you that.
While the disproportionate impact is clear, the reasons for it are not. Its a great mystery, Langston says. Researchers still dont know what it is that makes men more susceptible to Parkinsons, or what it is about women that may protect them or both. But they are trying to find out.
Parkinsons results from the death of key neurons in the substantia nigra region of the brain that produce the chemical messenger dopamine. Over time, the loss of these nerve cells disrupts movement, diminishes cognition, and can cause other symptoms, such as slurred speech and depression.
Such a Parkinsons study could do the same, she says.

Improving Life For Women With Parkinson’s Disease
As an audiologist, Sharon Krischer used her skills to help others improve their hearing. But for a long time, she couldnt hear what her own body was telling her.
The mother of three daughters and grandmother of four remembers writing thank you notes one day when her right foot started shaking. It continued happening occasionally, but the inconsistency made Krischer think nothing of it until she broke her opposite leg and the twitch in her right foot returned. This time it wasnt going away.
People living with Parkinsons disease can experience symptoms affecting their movement, as well as other health consequences.
Krischers internist prescribed anti-anxiety medication, but the tremor spread to her right hand. She saw a neurologist who said she had a Parkinsons-like tremor and prescribed an anti-Parkinson drug.
After experiencing hallucinations from the medication, her internist referred her to a movement disorders specialist at University of California, Los Angeles. There, 18 months after first seeing symptoms, she received a diagnosis of Parkinsons disease . She was 57 years old.
The first year is very, very hard if you are a young woman with PD because you dont know how people will react, Krischer said. Its also hard to go from being the caregiver to receiving care, especially if you have children.
How Might Parkinsons Affect Women
Although almost 50% of people with Parkinsons are women , there has been very little research into the additional challenges that women may encounter. In fact, most information is anecdotal rather than based on clinical research and tends to emerge as a result of the sharing of problems. However, not everyone is forthcoming with their difficulties so the overall picture is perhaps not truly representative of the broad range of experiences of Parkinson’s in women.

How Early Can Parkinson’s Disease Be Diagnosed
A: A true determination of Parkinson’s disease is a clinical diagnosis, which means certain motor symptoms have to be present, but we now know more about some early signs of Parkinson’s disease that, while they don’t always lead to the condition, are connected.
In terms of how early we can detect, we can detect a mutation that is associated with an increased risk of Parkinson’s as early as birth. In the minority of patients who may have a known Parkinson’s-related genetic mutation , that gene could be tested for at any time in life. At the same time, that’s not diagnosing Parkinson’s it’s just identifying the risk.
Early warning signs are what we call prodromal, or preclinical, symptoms. Prodromal symptoms are an early warning sign that someone might get Parkinson’s disease. Though some of these symptoms have a very high probability of signaling future Parkinson’s, having one or more of them is still not a 100 percent probability. Some prodromal symptoms are loss of sense of smell, REM behavior disorder, anxiety or depression, and constipation.
Is Parkinsons Disease Inherited
Scientists have discovered gene mutations that are associated with Parkinsons disease.
There is some belief that some cases of early-onset Parkinsons disease disease starting before age 50 may be inherited. Scientists identified a gene mutation in people with Parkinsons disease whose brains contain Lewy bodies, which are clumps of the protein alpha-synuclein. Scientists are trying to understand the function of this protein and its relationship to genetic mutations that are sometimes seen in Parkinsons disease and in people with a type of dementia called Lewy body dementia.
Several other gene mutations have been found to play a role in Parkinsons disease. Mutations in these genes cause abnormal cell functioning, which affects the nerve cells ability to release dopamine and causes nerve cell death. Researchers are still trying to discover what causes these genes to mutate in order to understand how gene mutations influence the development of Parkinsons disease.
Scientists think that about 10% to 15% of persons with Parkinsons disease may have a genetic mutation that predisposes them to development of the disease. There are also environmental factors involved that are not fully understood.

Men More Likely To Get Parkinson’s Disease
Men May Face Greater Risk of Parkinson’s Disease Than Women
Researchers analyzed several studies on the incidence of Parkinson’s disease in the population and found that men were 1.5 times more likely to develop the disease than women.
The cause of Parkinson’s disease is unknown, but symptoms of the disease, such as slow movements, tremors, and stiff muscles are caused by low levels of a chemical in the brain called dopamine.
About 1 million people in the U.S. have Parkinson’s disease, and the risk of developing the disease increases with age.
What Causes Parkinsons Disease
Parkinsons disease is a chronic, progressive neurological disease that currently affects about 1 million Americans. Parkinsons disease involves a small, dark-tinged portion of the brain called the substantia nigra. This is where you produce most of the dopamine your brain uses. Dopamine is the chemical messenger that transmits messages between nerves that control muscle movements as well as those involved in the brains pleasure and reward centers. As we age, its normal for cells in the substantia nigra to die. This process happens in most people at a very slow rate.
But for some people, the loss happens rapidly, which is the start of Parkinsons disease. When 50 to 60 percent of the cells are gone, you begin to see the symptoms of Parkinsons.

Pharmacological Therapy Of Motor Symptoms
In the absence of a disease-modifying therapy, PD treatment is currently based on the control of motor symptoms by levodopa supplementation. However, long-term therapy with levodopa is associated with the development of motor complications, such as levodopa-induced-dyskinesia, wearing off and on-off phenomena. It is generally assumed that dyskinesia is associated with sustained levodopa plasma levels . Commonly, women present greater levodopa bioavailability, which is further supported by lower levodopa clearance levels . Dopamine bioavailability in the central nervous system is dependent on the activity of two catabolic enzymes: catechol-O-methyltransferase and monoamine oxidase-B , whose encoding genes are located on the chromosome 22 and X chromosome, respectively . A study that explored the relationship between MAO-B or COMT functional SNPs and levodopa therapy reported that male PD patients carrying the MAO-B G allele had a 2.84-fold increased risk of developing motor complications when treated with high doses of levodopa .
Expressing And Interpreting Emotion
PD rigidity can cause the muscles of the face to freeze. This leads to a mask-like expression. As a result, patients with PD have difficulty expressing emotion with their faces. They also can begin to have difficulty interpreting others facial expressions.
One study suggests that both men and women with PD can have difficulty interpreting anger and surprise, and that men are more likely to lose the ability to interpret fear.
However, women may be more upset by their inability to interpret emotions. All PD patients may benefit from speech and physical therapy to help with this symptom.

Symptoms Of Parkinsons: Men Vs Women
Parkinsons disease in men and women
More men than women are diagnosed with Parkinsons disease by almost a 2 to 1 margin. Several studies support this number, including a large study in the American Journal of Epidemiology.
Usually there is a physiological reason for a difference in disease between men and women. How does being female protect against PD? And do women and men experience PD symptoms differently?
Where Are The Women
When I joined a Parkinsons disease association, my first question was, Where are the women?
The risk of developing Parkinsons disease is almost twice as high in men as in women, but women experience faster disease progression and a higher rate of mortality. It is important to know these differences, and more research is needed on the impact of Parkinsons on women.
Both men and women may suffer incomprehension when our body makes uncontrolled movements, and we all know what isolation and loneliness feel like. Women may also face paternalistic attitudes which undermine their authority in society. Imagine what it is like when we are also vulnerable due to a serious illness.
I think the use of healthcare resources is also different. Women do not abandon roles of wife and mother even when they are sick. And women are more likely to require paid caregivers, while men tend to have caregivers within the family: their wives.
As I found out more about the condition, I kept going over and over the same question in my mind: Where are the women?. So last November, three of my friends Anna Gómez, Laura Román and Teresa Borque and I decided to start a blog to give a voice to women with Parkinsons disease, and to raise awareness about how the condition affects us.

Living With Parkinson’s Disease
As Parkinson’s develops, a person who has it may slow down and won’t be able to move or talk quickly. Sometimes, speech therapy and occupational therapy are needed. This may sound silly, but someone who has Parkinson’s disease may need to learn how to fall down safely.
If getting dressed is hard for a person with Parkinson’s, clothing with Velcro and elastic can be easier to use than buttons and zippers. The person also might need to have railings installed around the house to prevent falls.
If you know someone who has Parkinson’s disease, you can help by being a good friend.
Women Have To Learn To Be Their Own Highest Priority In Life
I think the most important task for any organisation is to teach Parkinsons patients to take care of themselves. When we are diagnosed with Parkinsons, usually we know as much about the brain as anyone else almost nothing. Many patients end up sitting down, taking their medication and waiting for a cure. This is a very complex disease that requires very thorough management. Our quality of life largely depends on it.
I encourage women to stop trying to prove anything, with or without Parkinsons. We base our self-esteem on other peoples recognition of ourselves but women have to learn to be their own highest priority in life. We have to learn to say me first, we have to learn to say no on our own, without the consent of the group. We have to learn to be impervious to social judgment even more so if health is at stake.

What Is Rem Behavior Disorder And How Is It Connected To Parkinson’s
A: REM behavior disorder is different than other sleep problems, like insomnia. People who have it may jerk or kick it’s as though they are acting out their dreams. In a similar pattern to anosmia, people with idiopathic REM sleep behavior disorder have at least a 50 percent chance of eventually developing 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 Parkinsons Disease
Parkinsons disease is a progressive brain disorder that affects mobility and mental ability. If you or a loved one has been diagnosed with Parkinsons, you may be wondering about life expectancy.
According to some research, on average, people with Parkinsons can expect to live almost as long as those who dont have the condition.
Gender Differences In Clinical Symptom Presentation
In a larger-scale study, Scott and colleagues contrasted symptom characteristics at disease onset and later . Relative to onset, at time of second evaluation men listed more symptoms, though women reported that their symptoms caused them more distress . The investigators suggested the reporting differences may have arisen from âdifferences in social acceptance of communicating emotionality.â

Parkinson does follow a broad pattern. While it moves at different paces for different people, changes tend to come on slowly. Symptoms usually get worse over time, and new ones probably will pop up along the way.
Parkinsonâs doesnât always affect how long you live. But it can change your quality of life in a major way. After about 10 years, most people will have at least one major issue, like dementia or a physical disability.
Women And Parkinson’s Disease: What We Don’t Know
“It’s an unknown unknown,” Amie Hiller, M.D., says. She’s a neurologist at OHSU’s Parkinson Center and Movement Disorders Program, and she’s talking about how the impact of Parkinson’s disease on women might be different from the disease’s impact on men.
Parkinson’s disease is a neurological disorder that affects the nervous system. It’s a chronic disease that gets worse over time, and there is no cure. Parkinson’s disease can cause tremors, slowness, stiffness, and balance problems. In the advanced stages, it can impact cognitive function.
Most people diagnosed with Parkinson’s disease are over the age of 60, and as many as one million people in the United States have the disease. The disease is more common in men, but scientists don’t yet understand why.
As Dr. Hiller notes, this isn’t the only mystery about Parkinson’s disease, especially when it comes to women.
Outcomes may be worse for women
“Parkinson’s disease research has focused more on men, and we treat women the same way we treat men,” says Dr. Hiller. “We don’t know if the disease might behave differently in women.”
It’s possible that women are underdiagnosed due to symptoms presenting differently, or that the best treatment for women is different than the best treatment for men. Dr. Hiller is part of a team putting together a “Women and PD: TALK” forum at OHSU to tackle these questions.
