How Does Stress Affect Parkinson’s Patients

Q: Are There Any Studies Of The Effects Of The Covid

How does Parkinson’s disease and its treatment affect sexual functioning?

A: Currently, there is no data that the COVID-19 vaccine has any long-term negative effects on anyone, including those with PD. Some people with PD have reported a worsening of PD symptoms in the short term after vaccination, which then resolve. The Center for Disease Control instituted a vaccine safety monitoring system, called v-safe, which captures side effects of the vaccine. If you have side effects from the vaccine and have PD, you can alert the CDC using this system. This will be an invaluable tool for scientists to discover trends in vaccine side effect profiles.

Emotional Aspects Of Parkinsons

It is important to examine the various emotions that a person living with Parkinsons disease can undergo in living daily with the condition. The emotional factors that affect your loved one can be both internal and external. Some changes that occur can be directly due to the disease process, which causes an alteration in brain chemistry. Other emotional changes are influenced by external factors and the persons reaction to those factors.

Having a chronic neurological condition is stressful, and people react to stress in different ways. Some see it as a challenge and others see it as a problem. Parkinsons disease has a significant impact on family and friends and can create many emotions. These emotions include:


Denial, a feeling of shock and disbelief is a common reaction, especially at the time of initial diagnosis and early in the disease process. Since PD can have a subtle onset before an actual diagnosis is made, people often attribute symptoms to other causes. People also sometimes report a general feeling of uneasiness or an anxious, depressed feeling prior to diagnosis. When a diagnosis is finally made, it can come partially as a relief, but there is often shock and fear of the future.


Depression is one of the most common reactions to Parkinsons disease, occurring in roughly 50 percent of clients. Some doctors feel that depression may actually be part of the disease process. PD medications can also cause depression in some patients.

Serotonin Hypothesis Of Depression

Serotonin is mainly produced in the dorsal raphe nucleus . Serotonin transporters take up released serotonin from the synaptic cleft into serotonergic neurons in a manner that helps to modulate various functions in the brain including mood and emotion . The striatum, the amygdala, and the prefrontal cortex are regions of the brain that are innervated by serotonergic neurons . These brain regions including the dorsal raphe nucleus which is part of the brains serotonergic system, are activated during early maternal stress . Abnormal 5-HT levels in these brain areas have been associated with depression . Pre-clinical and clinical studies have demonstrated that early life stress affects 5-HT levels in the brain and this may lead to depression . Selective serotonin re-uptake inhibitors are a class of antidepressant drugs commonly used to treat depression . SSRIs work by blocking 5-HT re-uptake thus increasing the availability of 5-HT in the synaptic cleft as well as its chance to bind to receptors in the post-synaptic membrane . Therefore, by restoring the levels of monoamines and their transporters in the brain, SSRIs drugs are appropriate treatments to address early life stress dysfunction that predisposes to depression later in life.

The Case Of Fluvoxamine Maleate

The role of serotonergic drugs in PD associated with depression has been receiving considerable attention amongst the research community . As a link between DA and the development of depression in patients with PD has been suggested, the pathophysiological features of both PD and depression have in common DA pathway dysfunction and depletion and/or 5-HT deficit . It has been suggested that an increase in serotonergic tone may indirectly influence DA function and may contribute to increased motor activity which is partially blocked by DA antagonists . Studies have shown that depression may be associated with an abnormal level of DA . As studies have also shown that brain regions affected by abnormal DA processing may also be affected when 5-HT is abnormally processed, we hypothesize that Fluvoxamine maleate treatment may play a role in improving the chemical imbalance caused by low levels of DA in the brain .

The Five Environmental Causes Of Parkinsons Disease


Parkinsons disease is a brain disorder that develops and becomes worse over time. The typical symptoms of the disease include tremor, stiffness, slowness of movement, and balance problems.; These symptoms develop when the brain lost its ability to produce a sufficient amount of dopamine, a neurotransmitter responsible for controlled body movement.

Researchers have identified a variety of environmental factors that are linked to Parkinsons disease. Some of these factors may directly cause the disease symptoms, others may increase the risk of developing it.

Here are the 5 main environmental factors that are linked to Parkinsons disease development.

Q: What Side Effects Can I Expect From The Covid

A: While there have been some varied reactions, the COVID-19 vaccines are approved by the FDA and considered safe. Some people may simply experience a mildly sore arm and that is it . There are some who may have a more noticeable reaction and feel chills, body aches, headaches and/or fatigue for 1-2 days, but these generally clear up quickly.;There have also been some anecdotal reports of PD symptoms temporarily worsening after COVID-19 vaccination.

Weighing the risks of someone with PD getting COVID-19, as well as the significant downsides of all the pandemic-related restrictions on social and physical activities to someone with PD vs. the potential for side effects from the vaccine, I would favor getting the vaccine. As always, discuss all your medical concerns with your neurologist and primary care physician.

Q: Are There Any Reasons Why A Person With Pd Should Not Get A Covid

A: There are no substantiated scientific concerns to suggest that the vaccines have a different safety profile in people with PD as compared to the general population, so what we know about the vaccines for all-comers would hold true for those with PD.; Having PD might lead to;a more complicated infection should you contract COVID-19, plus people with PD also tend to be older which further increases the risk for complicated COVID-19 infection. Because of these issues, vaccination for COVID-19 for people with PD is a good idea. Discuss with your doctor any concerns you have about the COVID-19 vaccine.

Anxiety And Parkinsons Research

What does this finding mean for the future of diagnosis or treatment of Parkinsons? Ongoing research is compelling, says Pontone. Part of what we are doing is looking at anxiety disorders that occur long before the onset of Parkinsons to see if there are characteristics that may differentiate that anxiety or predict an increased risk of Parkinsons disease.

Meanwhile, because theres an established link between anxiety and Parkinsons disease, patients and their families should be upfront with their doctors about anxiety symptoms. Behavioral therapy and medications for example, anti-anxiety meds or antidepressants can effectively treat anxiety disorders. Theres no need for anyone to suffer in silence.

Managing Anxiety And Depression In Parkinsons Disease

Vlog #23 Stress and Anxiety in Parkinson’s Disease

A combination of medication and other therapies can help ease non-motor symptoms affecting those with Parkinsons disease.

Most people think of Parkinsons disease as marked only by tremors, muscular rigidity and slow, imprecise movements, but Parkinsons is more than a movement disorder.

Most people with Parkinsons also have quite a few non-motor symptoms, such as anxiety, depression and psychosis. Many of these symptoms may have started before the Parkinsons disease became obvious.

The effects are widespread. Several years ago, a large clinical study of more than 1,000 people with Parkinsons disease of various durations demonstrated that only 1.4 percent of the participants did not report any non-motor symptoms.In other words, 98.6 percent of the study participants had some form of NMS. Psychiatric symptoms accounted for 60 percent, while visual hallucinations that could have signified psychosis were present in about 35 percent of patients.

Thats why taking action is important. If you or a loved one has had a new diagnosis of Parkinsons disease, we recommend an immediate evaluation for depression, mood and cognitive problems. Frequent monitoring should also be done throughout the course of the disease.

Here are some of the common symptoms and treatment methods for Parkinsons patients with depression and dementia:

Stress Depression And Parkinsons: An Intertwined Story

Research has shown the implication of stress early in life with depression, a common symptom in Parkinson’s Disease. This link may provide a role for antidepressents in the treatment of Parkinson’s disease. Here Dr Ernest Dalle, author of newly published research in Molecular Brain,;tells us more.

Parkinsons disease is a neurodegenerative disease characterized by loss of dopaminergic neurons in part of the mid brain called the substantia nigra pars compacta for which there is no cure. Motor symptoms of PD appear at a late stage of the disease while psychiatric disorders known as non-motor symptoms frequently precede motor symptoms by many years.

Therefore, exposure to stress during early life can have long term effects on brain development and these effects include depression. More precisely, early exposure to emotional stress such as maternal separation has been shown to cause long-term neurochemical and behavioral changes later in life.

Depression is commonly associated with Parkinsons disease with an estimated prevalence of depression in 40 -50 % of PD cases. This high prevalence of depression in PD has prompted the idea that degenerated nigrostriatal system may play a key role in depression.

Neurobiological Aspects Of Stress And Depression

Appropriate responses to external or internal adversity are critical for adaptation and survival. The stress response involves the activation of multiple bodily systems, the most prominent of which are the HPA axis and autonomic nervous system. Activation of the HPA axis creates a neuroendocrine cascade that results in the elevation of glucocorticoid levels. Glucocorticoids subserve important adaptive functions during stress exposure , and also provide negative feedback regulation of HPA axis activation, thereby limiting their own secretion. While initially adaptive, protracted activation of the stress response contributes to physiological abnormalities and may be involved in the development of disease states . Mood disorders are often preceded by stressful life events, whether environmental or physiological , and chronic stress is considered an important risk factor for depression . Notably, glucocorticoid receptors are localized to many regions involved in depressive and neurological pathologies, including the prefrontal cortex , hippocampus, striatum, limbic system, nucleus accumbens, and ventral midbrain , suggesting the potential for glucocorticoids to play a role in disease processes.

Tips and Takeaways

  • Most people who are infected with COVID-19 will recover completely. However, older adults and those with underlying medical issues such as advanced PD are at an increased risk of developing serious outcomes from COVID-19 as compared to those who are younger and healthier.
  • Three COVID-19 vaccines have been approved in the US.
  • Getting vaccinated reduces your chances of contracting COVID-19, but those who are vaccinated can still contract COVID-19.
  • Vaccination is about 90% effective in protecting against severe illness, hospitalization, and death, even for the new Delta variant
  • Continue to monitor CDC guidelines for information on COVID-19.
  • Talk with your doctor about any concerns you have about COVID-19 or COVID-19 vaccines.

Environmental Toxins And Parkinsons Disease

Neuronal cell death in PD may also be triggered by exposure to toxic substances or environmental factors which precipitate the symptoms of the disease as they render the brain vulnerable to subsequent physiological chronic stress . The environmental cause of PD mainly refers to exposure to dopaminergic toxins 6-hydroxydopamine , 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine , paraquat and rotenone as these toxins are known to induce formation of reactive oxygen species and oxidative stress which may result in neuronal cell death .

DA is one of the common neurotransmitters present in most parts of the central nervous system . The mesocortical, mesolimbic, nigrostriatal and tubero-infundibular pathways are the four main pathways that play a key role in dopaminergic signaling . DA cannot cross the blood brain barrier, therefore, it is synthesized from tyrosine which is carried into the brain via amino acid transporters . At the dopaminergic neuron level, tyrosine is then converted into dihydroxyphenylalanine by tyrosine hydroxylase then finally into DA by aromatic L-amino acid decarboxylase . DA is then stored in the vesicle until an action potential allows the vesicle to be discharged into the synapse . Monoamine oxidase is the enzyme that is responsible for breaking down excess DA and is known to similarly act on 6-OHDA inducing oxidative stress resulting in apoptosis .

Noradrenaline Hypothesis Of Depression

Noradrenaline is known to play a role in the regulation of emotions . The deficiency of noradrenaline/norepinephrine mainly produced in the locus coeruleus and affecting certain brain areas such as the prefrontal cortex, the hippocampus or the hypothalamus has been associated with depression . Studies have shown that exposure to chronic stress including early maternal separation decreases noradrenaline levels within the brain leading to depression . This explains why selective norepinephrine re-uptake inhibitors , a new class of antidepressants that work by increasing norepinephrine levels in the brain, have been used to treat depression .
