In short
- FND symptoms are real and not imagined, exaggerated or your fault — the nervous system is not working properly, even though it is not damaged.
- The diagnosis is made by a neurologist using positive signs on examination, not only by ruling other things out.
- Understanding the diagnosis is part of the treatment, alongside approaches such as specialist physiotherapy and psychological therapy.
- Many people improve and some recover, but the course varies, and a clear, believed diagnosis is an important first step.

What is a functional neurological disorder (FND) assessment?
Functional neurological disorder (FND) is a condition where the nervous system is not working properly, even though the brain and nerves are not damaged. The symptoms are real and not imagined, made up or under your control. They can be very disabling and include limb weakness, tremor, walking problems, blackouts or seizure-like episodes (called dissociative or functional seizures), numbness, vision or speech problems, and difficulties with memory and concentration.
An FND assessment is a specialist neurology appointment to make the diagnosis. Importantly, FND is not simply a label given when tests are normal. A neurologist makes the diagnosis using positive signs on examination — for example, Hoover's sign for functional leg weakness, or specific features of a functional tremor — that show the nervous system can work normally in some situations but not others.
The assessment explains what FND is and is not. It is a problem with how the brain sends and receives signals (the software), not a structural disease (the hardware). Understanding this is itself part of treatment, because it points towards approaches such as specialist physiotherapy and psychological therapy that can genuinely help.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Options at a glance
These are the main approaches described in this guide. The right option depends on the diagnosis, your goals and what your clinician thinks is safe.
Functional limb weakness
Weakness of an arm or leg where examination shows the muscle can work in some situations but not others, such as a positive Hoover's sign.
Dissociative (functional) seizures
Episodes that can look like epileptic seizures or faints but have a different cause. Distinguishing them from epilepsy matters because the treatment is different.
Functional movement disorders
Tremor, jerks, spasms or abnormal postures that vary with attention and have specific examination features.
Functional sensory symptoms
Numbness, tingling, altered sensation or visual symptoms that do not follow the expected pattern of nerve damage.
Preparing for your test
- Write down your symptoms: what they are, when they started, what makes them better or worse, and how they affect daily life.
- Note any episodes or blackouts, and bring an account from someone who has witnessed them if you can.
- Bring a list of your medicines and any previous test results, scans or clinic letters.
- Note other symptoms that often accompany FND, such as fatigue, pain, poor sleep, low mood or anxiety.
- Think about your goals — for example walking better, fewer episodes, or understanding what is happening.
- It can help to bring someone with you for support and to remember what is discussed.
- Come prepared to discuss stresses or life events, while knowing FND is not caused by 'just stress' and is not your fault.
What happens
The neurologist takes a detailed history of your symptoms and how they affect you, and asks about episodes, mood, sleep, pain and previous health. They then examine you carefully.
A key part of the examination is looking for positive signs of FND, such as Hoover's sign or the way a functional tremor changes with distraction. These signs help confirm the diagnosis rather than relying only on normal tests.
Sometimes investigations such as an MRI scan, blood tests or, for episodes, an EEG are arranged — often to clarify the picture or because symptoms overlap with other conditions. The neurologist should then explain the diagnosis in plain language: that the symptoms are genuine, that the nervous system is not damaged, and how that understanding points towards treatments that can help. A good assessment ends with a clear explanation and a plan, not just reassurance that 'nothing is wrong'.
Is this test right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Anyone with sudden, new stroke-like symptoms — they need 999 emergency care, not a routine assessment.
- People whose picture clearly points to another acute neurological emergency needing immediate treatment.
- Those at immediate risk of self-harm, who need urgent mental health support first.
- A clinician without genuine FND experience, as a poor explanation can do real harm.
Delay or rearrange if…
- You have a new or rapidly changing symptom that needs urgent assessment in its own right.
- You are in mental health crisis or at risk of self-harm and need urgent support first.
- Key previous results or letters are missing and would help the assessment.
- An acute illness or infection is making your symptoms hard to interpret.
Alternatives to discuss
- NHS neurology assessment, which is the standard route.
- GP review and onward referral if symptoms are early or unclear.
- Specialist FND or neuropsychiatry services for complex or severe cases.
- Direct access to FND-trained physiotherapy or psychological therapy where available and appropriate.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Provides a clear, positive diagnosis rather than years of uncertainty
- Confirms that symptoms are genuine and explains why they happen
- Distinguishes FND from other conditions such as epilepsy or multiple sclerosis where needed
- Opens the door to treatments that can help, such as specialist physiotherapy and psychological therapy
- Reduces unnecessary repeated tests once the diagnosis is made
Risks & complications
- Emotional distress or relief when hearing the diagnosis
- Feeling dismissed if the diagnosis is not explained well
- Uncertainty if symptoms overlap with other conditions
- Disappointment that there is no single quick fix
- Difficulty accepting the diagnosis, especially if it was poorly communicated before
- Incidental findings on a scan that lead to further tests
- A coexisting condition being present alongside FND that also needs treatment
- A different, treatable diagnosis emerging later that changes the plan
- Significant low mood or thoughts of self-harm needing urgent support
The main risk in FND is a poor explanation, which can leave people feeling disbelieved or that they have been told the symptoms are 'all in the mind'. They are not. A good assessment gives a positive diagnosis based on examination signs and a clear, respectful explanation. If you feel dismissed, it is reasonable to ask the neurologist to explain how the diagnosis was made and what the plan is.
Published figures to discuss
Outcomes in FND vary widely. Some people improve substantially or recover, while others have persistent symptoms, and the course is hard to predict at diagnosis. A clear, believed diagnosis and access to appropriate therapy improve the chances of getting better, but no firm percentage can be given for an individual. Coexisting conditions, the type and duration of symptoms, and access to treatment all influence the outlook.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Misunderstanding the diagnosis as 'not real' | Common harmful pitfall | FND symptoms are real and potentially disabling; explanation should be positive and respectful, not dismissive. | Guide sourcesClinical context |
| Missing coexisting neurological disease | Recognised | FND can coexist with epilepsy, migraine, MS or other disorders, so assessment still needs careful neurology. | Guide sourcesClinical context |
| Over-investigation | Recognised | Repeated scans and tests can reinforce uncertainty when the clinical signs already support FND. | Guide sourcesClinical context |
| Recovery variability | Highly variable | Early explanation, physiotherapy/psychological therapy and addressing triggers help some people, but improvement is not instant or guaranteed. | Guide sourcesClinical context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is no physical recovery from the assessment. What happens afterwards is understanding the diagnosis, starting any therapy, and working towards your goals — improvement can take time and is rarely instant.
- Strong emotions on hearing the diagnosis, including relief, doubt or distress
- Needing time to understand what FND is and is not
- Symptoms that fluctuate from day to day
- Improvement that is gradual rather than immediate
- Setbacks at times of stress or illness, which do not mean the diagnosis is wrong
Aftercare
- Read trusted, neurologist-written information to understand the diagnosis.
- Engage with any recommended physiotherapy or psychological therapy.
- Set realistic, specific goals with your therapist or clinician.
- Look after sleep, pace activity, and manage pain and fatigue as advised.
- Tell your GP about the diagnosis so your care is joined up.
- Know who to contact for support and what to do during a setback.
- Seek urgent help if you have thoughts of harming yourself.
- A written account of your symptoms and episodes
- A witness account of any blackouts or seizure-like episodes
- A list of your medicines and previous test results
- Notes on mood, sleep, pain and fatigue
- Your goals for what you would most like to improve
- Someone to attend with you for support if possible
- Questions about how the diagnosis was made and what treatment is available
⚠ Get urgent help if…
- Thoughts of harming yourself or ending your life — seek urgent help now. Call 999 or go to A&E if you are in immediate danger, or call the Samaritans free on 116 123 at any time. For urgent advice you can also call NHS 111 in England, Scotland or Wales; in Northern Ireland, contact your GP out-of-hours service or your HSC Trust's Phone First service.
- A sudden, new or very different symptom from your usual pattern — get it checked, as it may be unrelated to FND
- Sudden severe headache, facial droop, new weakness or slurred speech — call 999 in case of stroke (FAST)
- A first-ever seizure, or a seizure-like episode that is longer or different from usual
- New problems with bladder or bowel control alongside weakness or numbness
- Rapidly worsening weakness or difficulty breathing or swallowing
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your specialist gives you.
Results & realistic expectations
A good outcome from an FND assessment is a clear, positive diagnosis that you understand and feel is believed, together with a plan. Knowing that the symptoms are genuine and that the nervous system is not damaged is reassuring for many people and is itself the first step of treatment.
The assessment cannot promise how quickly or fully you will improve, as the course of FND varies. It also cannot rule out every other condition forever; if symptoms change in a new way, that should be reviewed. The aim is a confident diagnosis, a clear explanation, and access to treatments that can help.
FND can improve, recover or persist, and the picture can change over time. The diagnosis and plan may need reviewing, especially after setbacks or if new symptoms appear. Treatment such as physiotherapy or psychological therapy may be needed in courses rather than all at once, and skills learned can be used again during flares.
Related tests, treatments or support
FND often sits alongside other symptoms such as chronic pain, fatigue, migraine, low mood or anxiety, and these may be addressed together. Some people have both FND and another neurological condition, such as epilepsy alongside dissociative seizures, so treatment is tailored to the whole picture.
Follow-up & long-term care
Follow-up usually involves starting the agreed therapies, reviewing progress, and adjusting the plan. Care is often shared between the neurologist, physiotherapist, psychologist and GP. Any new or changed symptoms should be reviewed rather than assumed to be FND.
- Ongoing physiotherapy or rehabilitation exercises for movement symptoms
- Psychological therapy skills to manage symptoms and setbacks
- Self-management of sleep, pacing, pain and fatigue
- Review of the diagnosis and plan if symptoms change
- Coordination between neurology, therapy services and the GP
Repeat, follow-on and what comes next
- The diagnosis may be reviewed if symptoms change in a way that does not fit FND.
- Some people have FND alongside another neurological condition, which becomes clearer over time.
- Treatment is often delivered in courses, and skills may need refreshing during flares.
- Reassessment is reasonable if a new, unexplained symptom develops.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A clear, respectful explanation that the symptoms are real, with written information.
- A concrete plan, including referral to FND-trained physiotherapy or psychological therapy.
- A named contact and advice on managing setbacks.
- Joined-up care between neurology, therapy services and the GP.
- A clear crisis and safety plan, including urgent mental health support if needed.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- The neurologist's appointment length, which may need to be longer than usual.
- The clinician's specific experience in FND, which affects the quality of diagnosis and explanation.
- Any tests arranged, such as an MRI scan, EEG or blood tests.
- Follow-up appointments and how the diagnosis is communicated.
- Access to specialist physiotherapy and psychological therapy, which are central to treatment.
- Coordination with your GP and other services.
- The neurologist's fee and the length of the appointment
- Whether the clinician specialises in FND
- Which tests are included and which are charged separately
- Follow-up arrangements and how the diagnosis is explained
- How referral to physiotherapy and psychological therapy is arranged
- What happens if the diagnosis is uncertain or symptoms change
On the NHS? FND assessment and treatment are available on the NHS through neurology and therapy services; private assessment may be used for speed or choice, provided the clinician genuinely specialises in diagnosing and explaining FND.

Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Being told only that 'nothing is wrong' or that tests are normal, without a positive explanation.
- Language that implies the symptoms are imagined, exaggerated or the person's fault.
- Not explaining which examination signs were used to make the diagnosis.
- No clear plan for treatment or who to contact.
- Failing to address related symptoms such as pain, fatigue or low mood.
Marketing red flags
- Promising a quick cure for FND.
- Offering unproven or expensive treatments without evidence.
- Claiming to diagnose FND from scans alone rather than clinical examination.
- Dismissive framing that suggests the symptoms are not genuine.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- How was my diagnosis made, and which positive signs did you find?
- Could my symptoms be caused by another condition, or could I have both?
- What treatments are available, and which is right for my symptoms?
- How do I access specialist physiotherapy or psychological therapy?
- What should I do during a setback or if a new symptom appears?
- Where can I find trustworthy information about FND?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my test, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this test not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
