Getting an MND Diagnosis: The Pathway and What to Insist On

Getting an MND diagnosis: thirteen months, and how to shorten them

The average Australian with motor neurone disease spends 13 months between noticing the first symptom and being told what it is. That figure comes from MND Australia’s 2025 report and it is worth holding against the other figure everyone quotes — an average survival of two to three years from diagnosis.

Put the two together and the arithmetic is unforgiving. More than a third of the time from first symptom to death is spent not knowing. And it is spent not knowing in a particular way: being treated for a trapped nerve, a back problem, a tennis elbow, stress, a small stroke that did not show on the scan. Reasonable management of reasonable hypotheses, one at a time, each taking six to twelve weeks to fail.

Nobody is being negligent in most of those thirteen months. MND is uncommon, the early signs genuinely look like commoner things, and there is no blood test for it. But some of the delay is avoidable, and this guide is about which part.

It covers why the delay happens, what the diagnostic pathway actually consists of, which conditions have to be excluded and why that matters, what to insist on if things are moving too slowly, and what to do in the first fortnight after a diagnosis is given. It is not a substitute for a neurologist. It is intended to make you a more effective participant in your own referral chain.

Why it takes thirteen months

Four reasons, and they stack.

There is no single test. Diagnosis is clinical — made by a neurologist examining the person, supported by investigations that mostly serve to exclude other things. MND Australia’s own description is that diagnosis “often takes several months and sometimes up to a year,” and that doctors must rule out other neurological conditions with similar early symptoms. You cannot order a test for MND the way you can order one for diabetes.

The first symptom is almost always mundane. A foot that catches on the carpet. A grip that fails on a jar lid. A voice that sounds tired by evening. Twitches in a calf. Any GP in Australia will see these presentations weekly, and in the overwhelming majority of cases they are not MND.

The base rate is doing the work, and it is usually right. A 58-year-old with a weak right hand is far more likely to have a cervical radiculopathy or an ulnar nerve entrapment than MND. Probability-based reasoning is good medicine and in this condition it generates a predictable, systematic delay.

And the referral chain is long. GP, then physiotherapy, then perhaps an orthopaedic surgeon or a sports physician, then imaging, then a neurologist, then nerve conduction studies and electromyography, then possibly a second opinion at a specialist clinic. Each step has a waiting list. Six steps at eight weeks each is eleven months without anybody doing anything wrong.

The pattern that should break the chain, and often does not, is progression and spread. A trapped nerve does not get worse every month. It does not move from one limb to another. It does not add slurred speech to a weak hand. Anything that is progressing steadily and spreading anatomically needs a neurologist, not another cycle of conservative management.

The signs that should prompt urgency

If you are reading this because something is not being taken seriously, these are the features that justify pushing:

Progressive weakness that has not plateaued. Weeks and months of steady worsening, with no better days.

Spread to a new region. It began in the right hand and now involves the right shoulder, or the left hand, or the leg.

Visible muscle wasting. A hollow between the thumb and index finger. A shoulder that has lost its contour. A tongue that looks shrunken or furrowed.

Fasciculations. Fine, continuous rippling twitches under the skin, often in the calf, thigh, shoulder or tongue. Benign twitching is common and usually harmless; twitching together with weakness and wasting in the same muscle is a different matter.

Painless weakness. Nerve entrapments and disc problems usually hurt. MND typically does not, at least at first.

Any bulbar symptom. Slurred or quieter speech, a change in voice quality, nasal speech, difficulty swallowing, coughing on fluids, drooling, or food catching. In an adult with no other explanation these warrant a neurologist promptly.

Weight loss without dieting.

A weak cough, breathlessness lying flat, waking with a headache, or needing more pillows. These indicate diaphragm weakness and should trigger both a neurological and a respiratory referral.

Both stiffness and wasting. Brisk reflexes in a wasted limb is an odd combination that points towards motor neurone involvement at both levels, and it is the pattern a neurologist is looking for.

One more, for completeness: personality or behaviour change preceding the weakness. In a minority of people, frontotemporal changes come first, and the family has been managing an unexplained character change for a year or two before any physical sign appears. See cognitive and behaviour change in MND.

The pathway, step by step

The GP. The job here is to get a neurology referral, and to get it with enough detail that it is triaged properly. A referral saying “weakness in right hand, please assess” will sit in a queue. A referral that says “progressive painless weakness and wasting in the right hand over four months, now involving the right shoulder, with fasciculations and brisk reflexes, no sensory loss, 4kg unintentional weight loss, query motor neurone disease” is triaged differently. Ask your GP to write the progression and the specific findings into the referral. Ask for it to be marked urgent.

The neurologist. The clinical examination is the central event in the whole process. A neurologist is looking for upper motor neurone signs (spasticity, brisk reflexes, clonus, extensor plantar responses) and lower motor neurone signs (wasting, weakness, fasciculations, reduced tone and reflexes) in the same person, in several regions, with sensation intact. That combination is the fingerprint. Many neurologists form a strong working impression at this first appointment, long before the tests return.

Nerve conduction studies and electromyography (NCS and EMG). The two key tests. NCS measures how well nerves conduct signals and helps distinguish nerve from muscle problems and identify treatable neuropathies. EMG involves a fine needle recording electrical activity in muscle; in MND it shows evidence of denervation and reinnervation — fibrillations, positive sharp waves, large motor units — in muscles supplied by different nerve roots and different regions. EMG is uncomfortable rather than painful, and it is diagnostically decisive in a way nothing else is.

MRI of the brain and cervical spine. Mostly to exclude other causes. This is where cord compression in the neck gets found, and it is important because that is surgically treatable and can closely mimic MND.

Blood tests. A broad panel to exclude mimics and treatable conditions: thyroid function, vitamin B12, creatine kinase, inflammatory markers, protein electrophoresis, anti-GM1 antibodies, HIV and syphilis serology in some cases, heavy metals where there is an exposure history, and tests for inflammatory neuropathies.

Lumbar puncture, sometimes, where an inflammatory or infective cause is being considered.

Respiratory function testing. Seated and lying forced vital capacity, and sometimes sniff nasal inspiratory pressure. This should be done at diagnosis as a baseline, not only when breathing becomes a problem. See breathing and MND.

Genetic testing, offered in some circumstances — particularly where there is a family history, where onset is young, or where identifying a SOD1 mutation would open access to tofersen, now subsidised on the PBS. Genetic counselling should come before testing, not after.

And a second opinion or referral to a specialist MND clinic. This is normal practice, not a sign of doubt about the first neurologist, and it is worth asking for. Multidisciplinary clinic attendance is associated with better outcomes.

The conditions that have to be excluded, and why it matters

This part of the process can feel like stalling when you want an answer. It is not. Several conditions mimic MND and some of them are treatable, which means getting this wrong in the other direction is worse.

Cervical spondylotic myelopathy. Degenerative compression of the spinal cord in the neck. Produces wasting and weakness in the hands with brisk reflexes and a stiff gait in the legs — upper and lower motor neurone signs together, which is exactly the MND pattern. Treated surgically. The single most important exclusion and the reason for the cervical MRI.

Multifocal motor neuropathy. Progressive asymmetric weakness without sensory loss, which looks very like lower-motor-neurone-predominant MND. It responds to intravenous immunoglobulin. Found on nerve conduction studies by identifying conduction block, and this is a large part of why NCS is done properly rather than briefly.

Chronic inflammatory demyelinating polyneuropathy. Immune-mediated, treatable.

Myasthenia gravis. Fluctuating, fatigable weakness that often affects eyelids, eye movements, speech and swallowing — easily confused with bulbar-onset MND. Treatable. Antibody tests and repetitive nerve stimulation distinguish it.

Inclusion body myositis. A muscle rather than nerve disease, weakening thigh and finger-flexor muscles with swallowing difficulty. Progresses slowly.

Kennedy’s disease (spinal and bulbar muscular atrophy). Genetic, X-linked, affects men, slowly progressive with a much better prognosis. Worth excluding by genetic test in men with slowly progressive bulbar and proximal weakness.

Spinal muscular atrophy, adult-onset.

Thyroid disease, severe B12 deficiency, lead or mercury exposure, Lyme disease in relevant exposure settings, and HIV-associated motor syndromes.

Benign fasciculation syndrome. Twitching without weakness or wasting. Common, harmless, and a very frequent reason people arrive at a neurologist terrified about MND. A normal EMG is reassuring here and the reassurance is real.

What to insist on, and how to say it

If the process is moving too slowly, these are the specific asks that work. Vague escalation does not; naming the thing you want does.

“Can you write the progression into the referral, and mark it urgent?” Triage decisions are made on referral letters. A letter describing steady monthly worsening and anatomical spread gets a different appointment than one describing a weak hand.

“Has motor neurone disease been considered and excluded?” A direct question, politely asked, forces an explicit answer. It also gets written in the notes, which matters for everything afterwards.

“Can I be referred for nerve conduction studies and EMG?” The decisive investigation. Knowing its name and asking for it by name changes the conversation.

“Can I have an MRI of the cervical spine?” The exclusion that matters most.

“Can I be referred to a specialist MND clinic?” Multidisciplinary clinics exist in most capital cities and attendance is associated with longer survival and better access to interventions. Ask early, and ask again.

“Can I have respiratory function tests as a baseline?” Seated and lying FVC. If weakness is progressing, this should not wait for breathlessness.

“Can I see the actual report?” Request copies of everything — imaging reports, NCS and EMG reports, clinic letters. You will need them repeatedly for funding applications and for second opinions, and getting them later is harder than getting them now.

And if you are near 65: ask whether an NDIS access request can be lodged on current functional impairment while the diagnosis is still being investigated. Access depends on age at application, the deadline does not move for anybody, and a thirteen-month diagnostic delay can be the difference between being in the scheme and never being eligible. See MND over 65.

Being told

Worth saying something about this, because how the diagnosis is delivered shapes the years that follow and the delivery is frequently poor.

What good practice looks like: a dedicated, unhurried appointment; a support person present; plain language with the words actually said rather than circled; an honest answer about prognosis if asked, framed as a range rather than a number; a clear statement of what can be done, because a great deal can; written information to take away; a named contact; and a follow-up appointment within weeks rather than months.

What happens too often: the diagnosis delivered at the end of a short appointment, alone, with a pamphlet, no follow-up booked and no idea what to do next.

If that is what happened to you, two things help. Ask for a second appointment specifically to go through it properly, with a support person — this is a reasonable request and most clinicians will make the time. And ring your state MND association on 1800 777 175 the same week. They do this every day. They will assign an MND advisor, explain what happens next, and tell you about the equipment loan library, which is frequently the first genuinely useful piece of information anybody provides.

The first fortnight

In order, because order matters more here than in almost any condition.

1. Ring the state MND association on 1800 777 175. Free. Get an advisor. Ask about equipment loans in the same call.
2. If the person is under 65, lodge the NDIS access request now, flagged urgent and requesting a priority eligibility decision. See MND and the NDIS. If over 65, ring My Aged Care on 1800 200 422 and ask for priority assessment, with a letter saying the condition is rapidly progressive.
3. Ask for referral to a multidisciplinary MND clinic.
4. Get the diagnosis in writing, with the type, the date, current function described in tasks, and the rate of change. Everything downstream needs this letter.
5. Ask for respiratory referral and baseline testing even if breathing is fine.
6. Ask for an occupational therapy assessment, functional and home.
7. See a solicitor about enduring power of attorney and enduring guardianship, while capacity is beyond question.
8. Find every insurance policy and superannuation fund and request the terminal illness and total and permanent disablement wording. Do this before resigning from anything.
9. Start voice banking if there is any speech change at all, and arguably even if there is not. It cannot be done retrospectively. See communication and voice banking.
10. Ask about palliative care referral. Early palliative involvement in MND is symptom management, not end-of-life care, and it is one of the most effective services available.
11. Tell two people you trust. Not everybody. Two.

What a multidisciplinary MND clinic actually does

Referral to a specialist clinic is the single recommendation in this guide with survival evidence attached to it — multidisciplinary care has been estimated to add seven to twenty-four months — and most people have no idea what one is or why it would make that much difference.

What it is. A clinic where the relevant disciplines see the person in the same place, usually on the same day, and talk to each other about them. Typically a neurologist, a respiratory physician or respiratory nurse, a speech pathologist, a dietitian, an occupational therapist, a physiotherapist, a social worker, a nurse coordinator, and often a palliative care clinician and an MND association advisor.

Why it works. Not because the individual clinicians are better, but because of what the structure prevents. Respiratory function gets measured at every visit rather than when somebody remembers. Weight gets tracked. The gastrostomy conversation happens before it is urgent. Ventilation gets discussed early rather than after a crisis. The equipment prescription anticipates the next six months. And the person makes one trip instead of seven, which in a condition where travel and waiting rooms are exhausting is itself a clinical intervention.

And because somebody is holding the whole picture. The failure mode in fragmented MND care is that every clinician manages their own part competently while nobody notices that the person has lost six kilos, stopped using their ventilator and cannot get into their bathroom.

The access problem. Clinics exist in most capital cities and are thin on the ground outside them, which is part of why Australian MND care varies by postcode. FightMND has committed $2 million to an Adelaide University-led project to produce Australia’s first national evidence-based MND care guideline, on the explicit basis that care pathways are currently inconsistent and that families face uncertainty and delays as a result. Until that lands, the clinic you can reach is the main determinant of the care you get.

What to do. Ask the neurologist for referral at the first appointment. Ask the state MND association on 1800 777 175 which clinic is nearest and whether they can help with the referral. If distance is the obstacle, ask whether the clinic offers telehealth review between visits, and whether a local team can carry out the measurements and send them in.
