POTS After a Concussion: Understanding Symptoms and Recovery

After a concussion, symptoms such as headaches, dizziness, and sensitivity to light or sound are often expected during the recovery process. However, some people notice a different set of symptoms emerging days or even weeks later. They may feel lightheaded when standing up, experience a racing heartbeat, struggle with unexplained fatigue, or find that routine activities suddenly feel more physically demanding.

Because these symptoms are not always associated with a typical concussion recovery, they can be confusing and easy to overlook. In some cases, they may be related to changes in the autonomic nervous system, including a condition known as Postural Orthostatic Tachycardia Syndrome (POTS). Understanding this connection can be an important step toward finding appropriate support and care.

What Is POTS? 

Postural Orthostatic Tachycardia Syndrome (POTS) is a form of dysautonomia, a group of conditions that affect the autonomic nervous system. This system controls many of the body’s automatic functions, including heart rate, blood pressure, digestion, temperature regulation, and blood flow.

In people with POTS, the body may have difficulty adjusting to changes in position, particularly when moving from sitting or lying down to standing. As a result, the heart rate can increase significantly, while blood flow may not be regulated as efficiently. This can contribute to symptoms such as lightheadedness, fatigue, brain fog, dizziness, rapid heartbeat, and exercise intolerance.

Because many of these symptoms overlap with those experienced during concussion recovery, POTS after a concussion can sometimes go unrecognized. A thorough evaluation may include a standing test or tilt table test, which measures changes in heart rate and blood pressure to assess how the autonomic nervous system responds to positional changes.

Can POTS Be Caused by Trauma? 

Research suggests that trauma, including concussions and other forms of traumatic brain injury, may contribute to the development of POTS in some individuals. While not everyone who experiences a concussion will develop autonomic dysfunction, changes in nervous system regulation can occur during the recovery process.

One study published in Activity and Exercise Intolerance After Concussion found that 11.4% of individuals diagnosed with POTS reported the onset of symptoms within three months of sustaining a concussion. Additional research has suggested that traumatic stress may affect autonomic balance, potentially disrupting the body’s ability to regulate heart rate, blood pressure, and circulation.

When the autonomic nervous system is not functioning efficiently, symptoms such as dizziness, lightheadedness, fatigue, exercise intolerance, and rapid heart rate may become more noticeable. Because these symptoms can overlap with common post-concussion complaints, the underlying cause may not always be immediately recognized.

Identifying autonomic dysfunction early can be an important part of the recovery process. Understanding the relationship between concussion and POTS may help guide a more targeted evaluation and support plan, particularly for individuals experiencing persistent or unexplained symptoms.

How Functional Neurology Can Help

Functional neurology can complement a conventional medical approach to managing POTS after a concussion. While traditional treatments often focus on managing symptoms such as rapid heart rate, blood pressure fluctuations, and dizziness, functional neurology evaluates how the brain and nervous system are functioning as a whole. By identifying areas of autonomic dysfunction, care can be tailored to support nervous system regulation and overall recovery.

Comprehensive Evaluation

The first step is understanding how the autonomic nervous system is functioning and whether neurological factors may be contributing to ongoing symptoms. A comprehensive assessment may include a review of medical history, symptom patterns, physical examination findings, and specialized testing.

Areas commonly evaluated include:

• Heart rate and blood pressure responses to positional changes
• Balance, coordination, and postural control
• Eye movements and visual tracking
• Sensory processing and neurological function
• Symptoms associated with autonomic dysfunction

This information helps create a clearer picture of how concussion-related changes may be affecting the body’s ability to regulate itself.

Individualized Treatment Plans

Because no two individuals experience POTS after a concussion in the same way, treatment plans are designed around each person’s unique needs and recovery goals. Depending on the findings, care may incorporate:

• Exercises that support autonomic nervous system function
• Balance and vestibular rehabilitation
• Visual-motor training and eye movement exercises
• Activities designed to promote neuroplasticity
• Strategies to improve tolerance to movement and activity

The goal is to support more efficient communication between the brain and body while addressing the specific challenges each individual faces.

Lifestyle and Dietary Recommendations

Recovery often involves more than rehabilitation exercises alone. Functional neurologists may recommend lifestyle adjustments that help support nervous system health and symptom management.

Recommendations may include:

• Maintaining proper hydration
• Supporting healthy sleep habits
• Gradually increasing activity levels
• Identifying factors that may worsen symptoms
• Nutrition strategies that support overall well-being

These adjustments can play an important role in helping the body better regulate heart rate, blood pressure, and energy levels throughout the recovery process.

Ongoing Support and Monitoring

Recovery from autonomic dysfunction can take time, particularly when symptoms develop following a concussion. Regular follow-up allows progress to be monitored and treatment plans to be adjusted as needed.

Ongoing care may help:

• Track symptom changes over time
• Identify improvements and remaining challenges
• Modify exercises and therapy recommendations
• Support long-term recovery goals

This personalized approach helps ensure that care continues to evolve alongside the individual’s recovery journey.
