Anxiety in Parkinson’s: Symptoms, Causes, and Treatment

Anxiety is a common non-motor symptom of Parkinson’s disease. It can appear as persistent worry, panic attacks, fear of crowds, fear of falling, social anxiety, or a general feeling of inner tension and unease. In some people, anxiety may even begin before the classic motor symptoms of Parkinson’s are clearly recognized. Research increasingly supports anxiety as an important psychiatric and non-motor manifestation of Parkinson’s, not simply a psychological reaction to the diagnosis. Anxiety in Parkinson’s can have several causes. Changes in brain chemistry, including dopamine, serotonin, and norepinephrine systems, may contribute. Anxiety can also be linked to medication fluctuations, “off” periods, freezing of gait, tremor, fear of falling, sleep problems, shame about visible symptoms, or the emotional burden of living with a progressive disease. Because anxiety can overlap with Parkinson’s motor symptoms, it is often recognized late.

This article explains how anxiety can show up in Parkinson’s, why it may happen, how it is diagnosed, and which treatments can help — from medication and cognitive behavioral therapy to exercise, relaxation techniques, music, and social support.

How common is anxiety in Parkinson’s?

Anxiety is one of the most common non-motor symptoms in Parkinson’s disease. Studies suggest that about one-third of people with Parkinson’s meet criteria for an anxiety disorder at a given point, and many more experience anxiety symptoms at some time during the course of the disease. Reported rates vary because studies use different definitions, scales, and patient groups.

Anxiety can occur on its own, but it often overlaps with depression, sleep problems, fatigue, apathy, motor fluctuations, and reduced quality of life. This is clinically important because anxiety can make Parkinson’s symptoms feel worse, reduce confidence, increase avoidance, and make everyday situations harder to manage.

What are the symptoms of anxiety in Parkinson’s?

Anxiety affects the body, thoughts, emotions, and behavior. In Parkinson’s, it can be difficult to recognize because some anxiety symptoms resemble Parkinson’s symptoms or medication-related changes.

Common signs of anxiety may include:

• A strong sense of inner restlessness
• Feeling tense, on edge, or unable to relax
• Muscle tension
• Feeling unsafe, threatened, or overwhelmed
• A strong urge to leave a situation
• Fear of losing control
• Shortness of breath or the feeling of not being able to breathe properly
• A racing or irregular heartbeat
• Sweating
• Shaking or trembling that is not caused by Parkinson’s tremor
• Persistent worrying about different areas of life
• Fast or deep breathing, also called hyperventilation, which may cause dizziness
• Trouble concentrating
• Sleep problems, including difficulty falling asleep, staying asleep, or lying awake for long periods at night

In Parkinson’s, anxiety may also appear as fear of freezing, fear of falling, fear of being unable to move in public, or fear that symptoms will become visible to others.

How anxiety and Parkinson’s symptoms can reinforce each other

Anxiety and Parkinson’s symptoms can create a difficult cycle. Anxiety can increase muscle tension, make tremor feel worse, disturb sleep, and reduce confidence while walking or speaking. At the same time, Parkinson’s symptoms such as freezing of gait, tremor, speech changes, balance problems, or unpredictable “off” periods can trigger anxiety.

For example, someone who freezes while crossing a street may become afraid of walking in public. That fear can lead to avoidance. Avoidance can reduce activity, confidence, balance, and social contact. Over time, this can increase both anxiety and functional limitations.

This cycle is one reason anxiety should be treated as part of Parkinson’s care. It is not “just nerves.” It can directly affect mobility, independence, social participation, and quality of life.

What types of anxiety can occur in Parkinson’s?

Anxiety in Parkinson’s can take different forms. Some people experience one main type, while others have several overlapping anxiety patterns.

Panic attacks and panic disorder

Panic attacks are sudden episodes of intense fear or distress. They may seem to come out of nowhere and often last several minutes, although some last longer. Symptoms may include shaking, shortness of breath, chest discomfort, sweating, dizziness, a racing heartbeat, or a feeling of losing control.

In Parkinson’s, panic-like symptoms may sometimes occur during medication wearing-off, but they can also happen independently of medication timing.

Generalized anxiety disorder

Generalized anxiety disorder involves persistent, excessive worry that is difficult to control. The worry may involve health, family, appointments, finances, safety, the future, or everyday responsibilities. People may not always be able to identify one clear reason for the anxiety, but the feeling can remain constant and exhausting.

Phobias

Phobias are intense fears of specific situations, places, or triggers. In Parkinson’s, these may include:

• Agoraphobia: fear of places or situations where escape might be difficult, such as crowds, public places, buses, trains, airplanes, or unfamiliar environments.
• Social anxiety disorder: fear of being watched, judged, misunderstood, or embarrassed in front of others.
• Acrophobia: fear of heights.
• Claustrophobia: fear of enclosed or narrow spaces.

Phobias can become especially limiting when they combine with Parkinson’s symptoms such as tremor, freezing of gait, balance problems, speech changes, or fear of falling.

What causes anxiety disorders in Parkinson’s?

Anxiety in Parkinson’s is usually multifactorial. It can be related to disease-related brain changes, medication fluctuations, motor symptoms, falls, social stress, sleep disruption, and the emotional impact of living with a progressive neurological disease.

Changes in brain chemistry

Parkinson’s affects several brain systems involved in mood, motivation, stress regulation, and emotional processing. The disease is strongly associated with the loss of dopamine-producing neurons, but anxiety and depression in Parkinson’s are not explained by dopamine alone. Serotonin, norepinephrine, and other neurotransmitter systems may also contribute.

Dopamine deficiency is closely linked to motor symptoms such as bradykinesia, rigidity, and tremor. Anxiety symptoms, however, often involve broader networks that regulate stress, arousal, sleep, mood, and threat perception. This is why anxiety should be treated as a real part of Parkinson’s, not dismissed as a purely emotional response.

Medication fluctuations and “off” periods

Parkinson’s medications such as levodopa/carbidopa are used to support dopamine signaling and improve motor symptoms. Over time, some people experience fluctuations in medication effect. During “off” periods, symptoms return or worsen as medication levels fall. These symptoms may include slowness, stiffness, tremor, freezing, dystonia, fatigue, low mood, or anxiety.

For some people, anxiety increases as medication wears off. They may feel physically slower, less mobile, more rigid, or less in control — and anxiety rises along with these changes. In others, anxiety may occur during “on” periods as well. This can reflect individual differences in brain circuits, medication sensitivity, emotional processing, or non-dopaminergic symptoms.

A symptom and medication diary can be very helpful. Tracking anxiety in relation to medication timing, sleep, meals, tremor, freezing, falls, and “on/off” periods can help the treatment team identify patterns.

Shame, embarrassment, and fear of being seen

Anxiety can also develop because people with Parkinson’s worry about how others will react to visible symptoms. Tremor, freezing of gait, slow movement, stiffness, speech changes, drooling, or reduced facial expression can feel difficult to hide. Some people fear being stared at, judged, misunderstood, or treated as less capable.

This can make everyday situations more stressful: eating in public, speaking in a group, walking through a crowded place, boarding public transportation, or attending a family event. The result may be avoidance, even when the person would like to stay socially active.

Falls and fear of falling

People with Parkinson’s may develop balance problems, postural instability, gait changes, or freezing of gait. Falls can be frightening and may cause serious injuries, especially near stairs, curbs, furniture, or hard surfaces.

After one or more falls, some people develop a strong fear of falling again. This fear is understandable, but it can lead to reduced movement and fewer activities. Moving less can weaken balance, strength, confidence, and social participation — which may then increase both fall risk and anxiety over time.

How is anxiety in Parkinson’s diagnosed?

Anxiety in Parkinson’s is often recognized late. One reason is that anxiety symptoms can overlap with Parkinson’s motor symptoms or medication effects. Trembling, inner restlessness, muscle tension, sweating, sleep problems, or difficulty concentrating may be attributed only to Parkinson’s, even when an anxiety disorder is also present.

People with Parkinson’s should speak openly with their neurologist, primary care physician, psychiatrist, psychologist, or other healthcare professional if they experience panic attacks, persistent worry, sleep problems, fear of falling, avoidance, or anxiety that interferes with daily life.

The earlier anxiety is recognized and treated, the better the chance of improving quality of life and preventing avoidance from becoming more entrenched.

Medical history, questionnaires, and tests

Doctors may use several tools to evaluate anxiety in Parkinson’s.

• Medical history: The clinician asks about symptoms, timing, frequency, duration, triggers, sleep, falls, medication use, “off” periods, and whether anxiety appears in specific situations.
• Medication review: Anxiety can be related to wearing-off, medication side effects, sleep problems, or other treatments. A careful medication review can help identify patterns.
• Symptom and medication diary: A diary can help track whether anxiety occurs before the next medication dose, during freezing episodes, after poor sleep, in crowded places, after falls, or at certain times of day.
• Questionnaires: Parkinson-specific tools such as the Parkinson Anxiety Scale, or PAS, can help assess anxiety severity and anxiety patterns in Parkinson’s. Recent validation data support the English self-rated PAS as a reliable screening and severity tool for people with Parkinson’s.
• Screening for other causes: Blood tests may be used in some cases to rule out contributors such as thyroid overactivity, vitamin deficiencies, medication effects, or other medical conditions.

How is anxiety in Parkinson’s treated?

Treatment should be individualized. The right approach depends on the type of anxiety, Parkinson’s stage, medication schedule, sleep, cognition, fall risk, depression, daily routines, and the person’s goals.

For many people, treatment works best when it combines Parkinson’s medication optimization, mental health care, psychotherapy, exercise, relaxation training, and practical self-management strategies.

Medication options

Medication may be helpful when anxiety is persistent, severe, linked to depression, or significantly interferes with daily life. Medication decisions should be made with a clinician who understands Parkinson’s, because some drugs can affect movement, cognition, sleepiness, balance, or fall risk.

• SSRIs and SNRIs: Selective serotonin reuptake inhibitors, or SSRIs, and serotonin-norepinephrine reuptake inhibitors, or SNRIs, are commonly used to treat anxiety and depression. Examples include medications such as citalopram or venlafaxine. These medications may take several weeks to work and should be monitored for side effects, interactions, and tolerability.
• Other medications for selected cases: In some situations, clinicians may consider other medications, such as pregabalin, especially when generalized anxiety or panic symptoms are prominent. This is not a universal first-line Parkinson’s anxiety treatment; use depends on the individual situation, other medications, and side effect risk.
• Adjusting Parkinson’s medication: If anxiety is closely linked to wearing-off or “off” periods, the Parkinson’s medication schedule may need to be reviewed. Adjusting levodopa/carbidopa timing, dose, formulation, or add-on therapy may help when anxiety rises as motor symptoms return. Dopamine agonists can also affect mood and anxiety in some people, but they require careful monitoring because they can cause side effects such as sleepiness, hallucinations, swelling, or impulse control disorders.
• Benzodiazepines: Medications such as lorazepam or clonazepam can reduce anxiety quickly, but they carry important risks in Parkinson’s. They can cause sedation, confusion, balance problems, dependence, and increased fall risk. For that reason, they are generally used cautiously, usually only for short periods or specific situations when other options are not sufficient.

Cognitive behavioral therapy for anxiety in Parkinson’s

Cognitive behavioral therapy, or CBT, is one of the best-studied psychological approaches for anxiety. In CBT, people learn to recognize anxiety patterns, understand how thoughts and behaviors can maintain anxiety, and practice strategies that help them respond differently. Reviews suggest CBT can be helpful for anxiety and depression in Parkinson’s, although more high-quality Parkinson-specific trials are still needed.

CBT may include:

• Breathing techniques for acute anxiety or panic
• Strategies to calm the body during moments of tension
• Identifying anxious thoughts and replacing them with more helpful thoughts
• Gradual exposure to feared situations
• Planning ways to remain socially active despite Parkinson’s symptoms
• Building confidence in situations that have become difficult
• Addressing avoidance, fear of falling, or fear of being seen with symptoms

The goal is not to pretend that Parkinson’s is easy. The goal is to prevent anxiety from controlling daily life and to help people regain confidence, flexibility, and participation.

What can help with anxiety in Parkinson’s?

Medication and psychotherapy can be important, but they are not the only tools. Many everyday strategies can help reduce anxiety, support mood, improve sleep, and create a stronger sense of control.

The goal is to stay active, stay connected, and build positive experiences that help anxiety take up less space.

Music therapy and singing

Music can support relaxation, mood, social connection, and emotional expression. Singing in a choir can be especially helpful because it combines breathing, voice, rhythm, social contact, and shared enjoyment. For people with Parkinson’s, singing may also support speech and voice confidence.

Listening to calming music, favorite music, or learning an instrument may also support mood and reduce stress.

Exercise and movement

Exercise is one of the most important supportive strategies in Parkinson’s care. Activities such as dancing, table tennis, swimming, Nordic walking, boxing, tai chi, strength training, and walking can support physical health, mobility, mood, and confidence.

Exercise can help reduce stress, improve sleep, and support neurotransmitter systems involved in mood and motivation. Group-based exercise can be especially helpful because it adds social connection. The right program should be adapted to the person’s abilities, fall risk, and medical situation.

Relaxation techniques

Relaxation methods can help calm the nervous system and reduce the physical tension that often comes with anxiety. Helpful options may include:

• Yoga
• Meditation
• Mindfulness
• Progressive muscle relaxation
• Tai chi
• Qigong
• Breathing exercises

With regular practice, these techniques may help reduce stress, improve body awareness, and strengthen confidence in managing difficult moments.

4-7-8 breathing for acute anxiety

For acute anxiety, a simple breathing technique may help:

• Breathe in through your nose for 4 seconds.
• Hold your breath for 7 seconds.
• Breathe out slowly through your mouth for 8 seconds, with your lips slightly parted.
• Repeat the cycle several times.

Focus only on your breathing while you do the exercise. If holding your breath feels uncomfortable, shorten the counts and breathe in a way that feels safe and manageable.

Social connection and support groups

Regular contact with people you trust can make anxiety easier to manage. Friends, family members, support groups, and Parkinson’s communities can provide reassurance, practical advice, and a sense of belonging.

A Parkinson’s support group can be especially valuable because it connects you with people who understand the disease from lived experience. These groups can reduce isolation, provide practical strategies, and sometimes lead to new friendships.

When should you seek help?

You should seek professional help if anxiety affects your sleep, movement, medication routine, relationships, social life, or ability to leave the house. You should also talk to a healthcare professional if you have panic attacks, intense fear of falling, persistent worrying, increasing avoidance, or symptoms of depression.

Contact your neurologist or Parkinson’s care team especially if anxiety appears to follow a medication pattern — for example, if it regularly occurs before the next levodopa dose, during “off” periods, with freezing, or as movement symptoms return.

Anxiety in Parkinson’s is common, but it is not something you simply have to accept. With the right diagnosis, treatment, and support, many people can reduce anxiety, regain confidence, and participate more fully in daily life.
