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.
Medical experts believe that environmental causes may help trigger Parkinson's disease. Exposure to farming chemicals, like pesticides and herbicides; Vietnam-era exposure to Agent Orange; and working with heavy metals, detergents and solvents have all been implicated and studied for a clearer link.
What can trigger Parkinson's? The cause of Parkinson's is unknown, but a stressful or traumatic event can sometimes trigger symptoms. After the death of a family member, a big operation, or a car accident, tremors may become very prominent. Additionally, stress, anxiety, and sleep deprivation always make tremors worse.
Anxiety as an Early Warning Sign
Parkinson's disease, like Alzheimer's disease, has what experts call a long approach, he says, and anxiety may be part of that long approach. One theory is that the anxiety that comes before Parkinson's results from the same underlying changes in brain chemistry and circuitry.
Rapid-onset dystonia-parkinsonism (RDP) is a very rare movement disorder, characterized by the abrupt onset of parkinsonism and dystonia, often triggered by physical or psychological stress.
The first symptom may be a barely noticeable tremor in just one hand. Tremors are common, but the disorder may also cause stiffness or slowing of movement.
While people are diagnosed with Parkinson's at an average age of 60, anything younger than 50 is considered young-onset Parkinson's, or YOPD.
Parkinson's disease (PD), like most common disorders, involves interactions between genetic make-up and environmental exposures that are unique to each individual. Caffeinated-coffee consumption may protect some people from developing PD, although not all benefit equally.
“Movement, especially exercises that encourage balance and reciprocal patterns [movements that require coordination of both sides of your body], can actually slow progression of the disease,” she says.
Anxiety: Symptoms and treatment
Cognitive behavioral therapy. Psychotherapy. Relaxation techniques. Adjust the carbidopa-levodopa (Sinemet) regiment to treat any anxiety that occurs during medication “off” times.
What causes Parkinson's disease? The most prominent signs and symptoms of Parkinson's disease occur when nerve cells in the basal ganglia, an area of the brain that controls movement, become impaired and/or die. Normally, these nerve cells, or neurons, produce an important brain chemical known as dopamine.
How long does it take for Parkinson's disease to progress? The progression of PD varies, and it can range from a few years to several decades. This partly depends on when the first symptoms begin. For example, in people who develop PD before age 50, the symptoms often take a long time to progress — 20 years or longer.
Although tremor in particular tends to worsen when a person is anxious or under stress, all the symptoms of PD, including slowness, stiffness, and balance problems, can worsen. Symptoms, particularly tremor, can become less responsive to medication.
Because Parkinson's primarily affects people as they grow older, the steady increase in humanity's average age means an inevitable increase in the prevalence of Parkinson's.
Most cases of Parkinson's aren't hereditary. But people who get early-onset Parkinson's disease are more likely to have inherited it. Having a family history of Parkinson's disease may increase the risk that you'll get it. This means that having a parent or sibling with Parkinson's slightly increases the risk.
By the time Parkinson's is diagnosed, most people have lost an estimated 60 to 80 percent of their dopamine-producing cells in the substantia nigra. While loss of dopamine accounts for the characteristic features of the disease, recent studies have revealed that a number of other brain systems are also damaged.
Parkinson's disease can't be cured, but medications can help control the symptoms, often dramatically. In some more advanced cases, surgery may be advised. Your health care provider may also recommend lifestyle changes, especially ongoing aerobic exercise.
Studies show targeted nutrition may slow Parkinson's advancement. Eating a whole-food, plant-based, Mediterranean-style diet — including fresh vegetables, fruit and berries, nuts, seeds, fish, olive and coconut oils and more — may be linked to slower PD progression.

The U.S. Food and Drug Administration (FDA) recently approved a new, easy-to-break levodopa/carbidopa tablet. Avion Pharmaceuticals' Dhivy can be taken whole or easily snapped in half or quarters for smaller, more precise dosing.
Because the symptoms of Parkinson's vary and often overlap other conditions, it is misdiagnosed up to 30% of the time, Dr. Fernandez says. Misdiagnosis is even more common in the early stages.
Green Tea Intake and Parkinson's Disease Progression: A Mendelian Randomization Study. Epidemiological studies have suggested green tea intake was associated with a reduced risk of Parkinson's disease (PD). However, whether green tea intake has an effect on PD progression is unknown.
Years can pass before symptoms are obvious enough to make a person to go to the doctor. There's no 'one size fits all' when it comes to Parkinson's disease — different people will experience different symptoms, and of varying severity.
In fact, recent research confirms that the average life expectancy for a patient with PD onset at age 60 is 23.3 years (83.3 total years of age). This is directly comparable to the latest United States Life Tables published in 2020 as part of the National Vital Statistics Reports.
If a person receives a diagnosis of Parkinson's disease before the age of 50 years, this is called early onset Parkinson's disease. The person may have the hallmark symptoms of tremor, rigidity, and slowness of movement, but confusion and balance problems are less likely than with a later diagnosis.
