Understanding Functional Neurological Disorder and the Mind-Body Connection

Functional Neurological Disorder, or FND, is a condition that affects many people yet remains widely misunderstood. If you or someone you know has been experiencing unexplained neurological symptoms, understanding what FND actually is (and what it is not) can make a real difference to how you approach your wellbeing.

What is Functional Neurological Disorder?

Functional Neurological Disorder is a condition in which the brain sends and receives signals in ways that produce real, involuntary neurological symptoms. These can include:

• Weakness or paralysis
• Seizures or episodes of shaking
• Sensory changes
• Difficulty with movement or coordination

The word “functional” refers to how the brain is functioning, not to any structural damage. Brain scans in people with FND often look normal because there is no physical injury or disease to detect. This does not mean the symptoms are imagined. They are very real, and they arise from genuine changes in how the brain’s networks are operating.

To understand Functional Neurological Disorder, we need to recognise the mind-body connection.

FND is not “all in the mind”

One of the most harmful misconceptions about Functional Neurological Disorder is that it is somehow made up or exaggerated. This could not be further from the truth.

For several years, FND was viewed purely through a psychological lens. The older theory suggested that emotional distress or repressed trauma was “converted” into physical symptoms. While this may be relevant for some individuals, we now understand it to be far more complex.

Many people with FND are not depressed or anxious, and have no history of psychological illness or adverse childhood experiences. Meaning FND does not require a psychological cause, and it’s important that this is understood both by those living with the condition and by the people around them, because stigma only adds to the burden of an already challenging experience.

The brain, the body, and life experience

Modern research shows that FND sits at the intersection of neurology, the body, and lived experience. Stressful life events, both recent and from earlier in life, may increase a person’s vulnerability to developing FND. 

Trauma can influence how the brain processes signals, how the nervous system responds to threat, and how the body interprets physical sensations. For some people, these factors play a role in the onset or continuation of symptoms.

It is also worth noting a growing area of interest around FND and COVID-19. Since the pandemic, a number of people have reported new or worsening neurological symptoms following infection, and in some cases, these overlap with FND. The pandemic itself also created conditions of prolonged stress, fear, isolation, and loss that placed considerable strain on the nervous system, even for those who were not consciously aware of feeling traumatised.

Internal, unprocessed stress can manifest in a variety of ways:

• Chronic overwhelm
• Emotional suppression
• Hypervigilance

When this kind of internal pressure combines with physical illness or significant life disruption, the brain and nervous system can become more vulnerable. For some people, this creates the conditions in which functional symptoms emerge.

A holistic approach to Functional Neurological Disorder

Understanding FND as a disorder of brain functioning rather than brain damage opens the door to a more compassionate and complete approach to care. 

Rather than looking for a single cause or assigning blame, a holistic perspective considers the relationship between the brain, the body, the nervous system, and a person’s life experiences.

This is where counselling and psychotherapeutic support can play a meaningful role. While counselling does not treat the neurological aspects of FND directly, it can help with the emotional weight that often accompanies a chronic or confusing health condition. 

Living with unpredictable symptoms, navigating a stretched healthcare system, managing the impact on daily life, and processing any underlying stress or trauma are all areas where talking in a supportive environment can genuinely help.

It is also important to recognise that for some people with FND, past experiences such as domestic abuse, prolonged stress, or adverse life events may have had an impact on their nervous system and overall mental health. Exploring these experiences in a safe, supportive space can be an important part of a wider journey towards recovery and wellbeing.

Navigating FND with support 

If you are living with Functional Neurological Disorder, or if you are struggling with the emotional and psychological impact of a health condition you do not fully understand yet, support is available. 

Counselling offers a space to make sense of your experiences, process what you are carrying, and find a way forward that feels right for you.

I offer Psychotherapeutic Counselling in a warm, non-judgemental environment, with specialist approaches including Sandplay therapy and dog therapy, which can be particularly helpful for those who find it difficult to put their experiences into words.
