Does Parkinson’s Cause Anxiety

Medication Not Working The Way It Used To

Ask the MD: Depression and Anxiety in Parkinson’s Disease

In the early stages, taking medicine works well to get rid of symptoms. But as Parkinsons progresses, your medication works for shorter periods of time, and symptoms return more easily. Your doctor will need to change your prescription.

Dr. Valerie Rundle-Gonzalez, a Texas-based neurologist, says to pay attention to how long your medicine takes to kick in and when it stops working. She says you should feel like symptoms significantly improve or are almost gone while on medication.

Parkinsons Disease And Anxiety: Causes And Treatments

It’s no surprise that Parkinson’s disease and anxiety go hand-in-hand. However, the level of anxiety in a person with PD does not always correspond with their degree of illness or disability. It’s easy to assume that anxiety is just another offshoot of Parkinson’s disease and a result of the emotional challenges of a long-term illness. However, Parkinson’s disease anxiety is not just feeling nervous or unsure about your condition; it is a clinical syndrome that deserves proper recognition and treatment.

What Are The Symptoms Of Parkinson Disease

Parkinson disease symptoms usually start out mild, and then progressively get much worse. The first signs are often so subtle that many people don’t seek medical attention at first. These are common symptoms of Parkinson disease:

  • Tremors that affect the face and jaw, legs, arms, and hands
  • Slow, stiff walking

Pessimism And Anxiety Linked To Parkinson’s

Researchers See Connection Between Personality Traits and Development of Parkinson’s Disease

“This is the first study to show that people with high levels of an anxious or pessimistic personality are at higher risk for developing Parkinson’s disease up to several decades later,” says James Bower, MD, a neurologist at the Mayo Clinic in Rochester, Minn., and a researcher on the study.

The researchers followed nearly 5,000 men and women who took a standardized personality test between 1962 and 1965; 128 of them developed Parkinson’s disease over the next 35 to 40 years.

People who scored highest on anxiety scores were 60% more likely to develop Parkinson’s disease than those scoring lower, Bower says. And those who scored in the top 25% on the pessimism scale were 50% more likely to develop the progressive neurological disease, he tells WebMD.

The people who developed Parkinson’s disease had anxieties that go beyond common worries about what’s for dinner or job stress, Bower says. “These are the chronic worriers — the people who worry about things that most people never seem to worry about.”

Parkinson’s disease, a disorder that affects nerve cells in the part of the brain controlling muscle movement, is characterized by trembling, muscle rigidity, difficulty walking, and problems with balance and coordination. These symptoms generally develop after age 50, although the disease affects a small percentage of younger people as well.

How Does Anxiety Cause Freezing Of Gait

Does Anxiety Cause Hand Tremors

Recently, imaging studies have begun to identify neural correlates associated with freezing behaviour. Although these studies did not focus on inducing anxiety to provoke freezing of gait, it is interesting that decreases in activation were found in the medial prefrontal cortex, left anterior insula and left ventral striatum during motor arrests compared to walking . Although these regions are involved in an array of functions such as the cognitive control network , these areas also have a well-established role in emotional processing . A recent review highlighted that nearly 60% of emotional induction studies reported activation of the insula , and furthermore the insula has been suggested to participate in evaluation of distressing thoughts and interoceptive emotional responses . Imaging results have also shown that Freezers have significantly less BOLD signal in the bilateral anterior insula and bilateral ventral striatum compared to Non-Freezers during simulated walking in virtual reality with increased cognitive load . Taken together, these results align with the current findings and theoretical framework suggesting that dysfunctional processing of emotional information in the ventral striatum might be one explanation of the current results showing that anxiety increased freezing of gait.

Identifying And Treating Depression

Between 17 to 50 percent of patients with Parkinsons have depression. Depression and Parkinsons have so many similar-looking symptoms that it is hard to tell the difference between them.

Its important to note, however, that depression is not a reaction to the disability. Rather, it seems to be related to the degeneration of specific neurons in Parkinsons disease itself.

Typical symptoms include:

Does Anxiety Cause Freezing Of Gait

Although baseline levels of anxiety were not different between groups, anxiety induced during the walking paradigm was significantly amplified in Freezers beyond the level of Non-freezers. This would suggest that in Freezers, goal-oriented movement has the potential to induce greater anxiety, leading to a cautious and potentially maladaptive movement response such as freezing of gait. Thus, in other circumstances such as walking in darkness, or approaching doorways and narrow spaces, the anxiety-driven need for cautious movement might explain the occurrence of freezing in these situations. One might question whether freezing precedes anxiety or if anxiety does in fact lead to a freeze episode. Panic attacks and heart rate increases have been identified prior to and during a freezing episode. However, inferring a causal relationship would be difficult since there was no manipulation of anxiety-inducing conditions. Rather, associations make it ambiguous as to whether panic attacks and autonomic responses provoke freezing of gait or are a reactive response. The current findings support and extend this research, demonstrating that anxiety is in fact a cause of freezing of gait rather than simply a response, since manipulations of anxiety directly influenced the amount of freezing of gait participants experienced. Spatiotemporal gait changes , which have been previously linked with freezing behaviour, were also increased when anxiety was heightened.

What The Research Says

Researchers believe that depression and anxiety in Parkinson’s are;due to changes in brain chemistry;that are caused by the disease itself. The same pathways that create dopamine in the brain which are impacted in PD also create the brain chemical serotonin, which regulates mood, appetite and sleep. Scientists think that the effect of Parkinson’s on serotonin, as well as other brain chemicals that support mood, is responsible for symptoms of depression and anxiety.

The Michael J. Fox Foundation actively pursues research that can shed light on the connection between mood changes and Parkinson’s and lead to treatment breakthroughs for people living with the disease. The MJFF-funded;Study of Antidepressants in Parkinson’s Disease;found that certain antidepressants eased depression in people with Parkinson’s without worsening movement symptoms. Still, more work remains to find more and better treatments for depression and anxiety. Researchers are looking at several different therapies: medications such as buspirone for anxiety, as well as cognitive behavioral therapy and non-invasive brain stimulation for both depression and anxiety.;Join recruiting studies in your area through MJFF’s online tool Fox Trial Finder.

Anxiety As An Early Warning Sign

It may be that anxiety disorders that are diagnosed as much as two decades before Parkinsons disease may be a harbinger of the disease, says Gregory Pontone, M.D., director of the Johns Hopkins Movement Disorders Psychiatry Clinic. Parkinsons disease, like Alzheimers 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 Parkinsons results from the same underlying changes in brain chemistry and circuitry. Others believe that Parkinsons disease and anxiety share a common genetic risk factor. Either way, taking a closer look at the link can help doctors understand the causes of Parkinsons and treat patients with the disease.

Depression And Parkinsons Disease

Depression can be a disabling symptom of PD, and it may negatively affect a persons long-term outcomes by causing them to withdraw from social situations, avoid activities like exercise, or being more reluctant to seek care. Some people experience depression as an early symptom of PD before the characteristic motor symptoms appear.2

Depression has a variety of symptoms, not all of which are experienced by every patient. Symptoms of depression can also range in severity or vary over time. Common symptoms of depression include:

  • Persistent sad, anxious, or empty mood
  • Feelings of hopelessness or pessimism
  • Feelings of guilt, worthlessness, helplessness
  • Loss of interest or pleasure in hobbies or activities, especially those which were previously enjoyable
  • Difficulty concentrating, remembering, and making decisions
  • Difficulty sleeping, early-morning awakening or oversleeping
  • Appetite and/or weight changes
  • Thoughts of death or suicide
  • Restlessness, irritability
  • Persistent physical symptoms3

There are many treatment options for depression that work well in people with PD. There are several types of antidepressants, including selective serotonin reuptake inhibitors , tricyclic antidepressants, and selective norepinephrine reuptake inhibitors . Many people also experience relief from their depression through psychological counseling, such as cognitive behavioral therapy. In addition, regular exercise has been shown to ease symptoms of depression.1,4

Anxiety And Laterality Of Parkinson’s Disease

A number of studies have examined the relationship between anxiety and laterality of parkinsonian symptoms. These studies have shown that anxiety in patients with Parkinson’s disease was associated with mainly left sided symptoms. If anxiety in patients with Parkinson’s disease was a psychological response to disability, then patients with right sided parkinsonism would be expected to be more anxious: in fact the opposite is the case.

Can Parkinsons Dementia Be Reversed


No specific cure has been identified for Parkinsons Disease Dementia. Rather, treatments have been aimed at reducing the symptoms of dementia and helping the patient maintain a high quality of life. Doctors treating patients of PD Dementia generally prescribe medications such as:

  • Antidepressants
  • Cholinesterase inhibitors
  • Clonazepam and L-dopa

Serotonin reuptake inhibitors are known to reduce depression symptoms. The ones widely prescribed by doctors include:

  • Prozac
  • Zoloft and
  • Lexapro

Cholinesterase inhibitors help reduce the effects of cognitive decline in people with dementia whereas Clonazepam helps enhance sleep quality. L-dopa helps reduce movement issues caused by PD but runs the risk of making confusion and dementia symptoms worse.

Doctors treating PD Dementia patients may also prescribe antipsychotic drugs but generally do so with caution, the reason being these reduce psychotic episodes but increase Parkinsons symptoms. The use of these drugs may also cause increased confusion and change in consciousness. For the record, Pimavanserin and Nuplazid have been identified as effective antipsychotic drugs.

What Is Aggressive Parkinsons Disease

As written above, Parkinsons dementia aggression is that form of Parkinsons which makes the patient exhibit aggressive behavior. They vent out their aggression either verbally or physically, in the various forms that have been written above. Besides verbal and physical outbursts, PD Dementia patients are also prone to hallucinating caused by the medication administered. Hallucinations in PD Dementia patients primarily occur because of the effects of dopaminergic agents for motor symptoms.

Loss of dopamine neurons in the ventral tegmental area is one of the likeliest of all neuropathological causes as changes in serotonin and norepinephrine systems are not. For the uninitiated, the ventral tegmental area is the origin of the mesolimbic dopaminergic projection. Plenty of studies have gone into analyzing the cause behind the aggression in PD Dementia patients. Depression in PD Dementia patients has been identified due to changes in the medial frontal cortex and the anterior cingulate. Akinetic-rigid variants have been found in patients showing signs of major depression.

What Are The Complications Of Parkinson Disease

Parkinson disease causes physical symptoms at first. Problems with cognitive function, including forgetfulness and trouble with concentration, may arise later. As the disease gets worse with time, many people develop dementia. This can cause profound memory loss and makes it hard to maintain relationships.

Parkinson disease dementia can cause problems with:

  • Speaking and communicating with others
  • Problem solving
  • Forgetfulness
  • Paying attention

If you have Parkinson disease and dementia, in time, you likely won’t be able to live by yourself. Dementia affects your ability to care of yourself, even if you can still physically do daily tasks.

Experts don’t understand how or why dementia often occurs with Parkinson disease. Its clear, though, that dementia and problems with cognitive function are linked to changes in the brain that cause problems with movement. As with Parkinson disease, dementia occurs when nerve cells degenerate, leading to chemical changes in the brain. Parkinson disease dementia may be treated with medicines also used to treat Alzheimer’s disease, another type of dementia.

What Are You Hoping To Find

Having zero anxiety would not be good for us. Fear has evolved to keep us safe from real danger. A person with no fear would not survive very long. However, no drug and no psychological treatment makes a person fearless. We are just aiming to turn down the level so it stops being unpleasant and problematic.

Reviewanxiety: An Ignored Aspect Of Parkinsons Disease Lacking Attention

Vlog #23 Stress and Anxiety in Parkinson’s Disease

Anxiety is a neuropsychiatric complication of Parkinsons disease .

Anxiety has been given less attention while treating PD.

Management of anxiety is crucial to improve quality of life of the affected patients.

Use of complementary based medicines could be beneficial.

Alternative approaches will lead to novel therapeutic treatment for PD and various complications associated with it.

Other Complementary Therapies For Anxiety In Pd

Complementary therapies are a growing group of treatments which may improve the symptoms of PD without medication. I have written past blogs on two complementary therapy approaches for several symptoms of PD art therapy and music therapy.

Various complementary therapy modalities have been developed that may lower stress and anxiety in PD. These include yoga, massage, the Alexander technique, neurofeedback and others. Some of these therapies have been studied in small trials with data suggesting that they may be helpful for the anxiety of PD. Others have not yet been studied, although anecdotally, people with PD may feel that they are very useful in combatting anxiety. In general, this group of therapies may be effective for the anxiety of PD but needs to be studied more rigorously.

As Well As Movement Symptoms People With Parkinsons May Also Experience Other Symptoms Such As Anxiety In This Blog We Explore The Research Into This Challenging Symptom

Anxiety is a feeling of unease, worry, fear or dread, although it can feel different for everyone. Anxiety also has physical symptoms, which can include sweating, heart palpitations, breathlessness, dizziness, indigestion and nausea. Sometimes, people experience symptoms of depression as well as those of anxiety.

Everyone feels anxious occasionally, and different situations perhaps a trip to the dentist or a flight will cause different people to feel anxious. For most people, these anxious moments are few and far between and are over quite quickly. For someone who struggles with anxiety, these feelings can happen more often, last longer, and feel more intense.

Anxiety is a normal response when we find ourselves in a threatening or dangerous situation. It exists to help us fight an enemy or flee from danger. A surge of adrenaline makes our hearts beat faster, our breathing deeper and blood rush to our muscles preparing us to deal with a stressful situation. Now that we do less fighting and running from danger, this response can be activated inappropriately.

Whilst anyone can experience anxiety, it is estimated that at any given time, around 31% of people with Parkinsons will have significant symptoms of anxiety.

What Is The Connection Between Parkinsons And Anxiety

Anxiety, like all behaviour and emotion, is ultimately controlled by our brain. Anxiety is related to a complex set of brain areas and chemicals, many of which are affected in Parkinsons. However, there is little evidence that dopamine is involved in anxiety. This means that dopamine medication tends to have little effect on whether a person feels anxious or not.

People with Parkinsons seem more prone to anxiety than people without. Some of this will be down to brain chemicals. However, some of it will be down to how anxiety and Parkinson’s interact. When stressed and anxious the symptoms of Parkinsons tend to get worse because of wide-spread effects on different systems in the brain. This in turn can make someone feel even more anxious, and so on, in a vicious circle.
