FND is sometimes referred to as Dissociative Neurological Symptom Disorder (DNSD), particularly in older diagnostic terminology. Both terms describe the same group of symptoms.

FND is recognised within contemporary neurological and psychiatric frameworks and sits at the intersection of brain functioning, emotional regulation, and stress physiology. Symptoms are real, involuntary, and can be debilitating without the right support.

How might FND present?

FND can present in a wide range of ways, including

• Dissociative (non-epileptic) seizures
• Functional limb weakness or paralysis
• Tremors or abnormal movements
• Speech or swallowing difficulties
• Sensory disturbances
• Episodes of collapse or unresponsiveness
• Severe fatigue or mobility impairment

Symptoms often fluctuate and may worsen during periods of stress, anxiety, sensory overload, or emotional distress.

For some individuals, FND develops in the context of trauma, prolonged stress, neurodevelopmental differences, or significant life events.

Understanding symptom reinforcement and escalation

Contemporary models of FND emphasise the interaction between neurological functioning, attention, emotional regulation and threat perception.

When symptoms are frightening or unpredictable, individuals may understandably become hypervigilant to bodily sensations. Increased monitoring, anxiety, and repeated medical investigations can unintentionally reinforce the brain’s threat response, making symptoms more persistent.

In structured or inpatient settings, if symptoms are responded to primarily through crisis management or increased restriction, without addressing stress regulation and functional confidence, this can contribute to dependency, fear of movement, and reduced autonomy.

Modern rehabilitation approaches highlight the importance of:

• Validation of symptoms
• Consistency in response
• Gradual functional exposure
• Rebuilding self-efficacy
• Reducing unnecessary medicalisation

What are the risks if FND is not understood?

Without coordinated, multidisciplinary support, individuals may experience:

• Reduced independence and mobility
• School or occupational disengagement
• Increased anxiety and avoidance
• Emotional distress and lowered confidence
• Repeated admissions or placement instability

Feeling invalidated or misunderstood can intensify distress and reinforce symptom patterns.

Recovery is possible, particularly when care integrates neurological understanding with psychological and functional rehabilitation.

FND-informed treatment at Ellern Mede

Ellern Mede provides formulation-led, multidisciplinary inpatient care for individuals with FND and related functional presentations.

Our approach may include:

• Consultant psychiatric and medical oversight
• Psychological therapy addressing stress, trauma, and emotional regulation
• Occupational therapy to rebuild functional skills
• Physiotherapy input where appropriate
• Sensory and environmental adaptations
• Family involvement and psychoeducation

Across our services, we offer different levels of support across our ward environments. This enables individuals to move through treatment pathways as their mental health improves and independence increases.

Restrictive measures are used only where necessary for safety, are proportionate, and are subject to regular multidisciplinary review. Our aim is to steadily restore autonomy and self-efficacy wherever possible.
