Executive summary
- Think MND in adults with slowly progressive limb or neck weakness, muscle wasting, fasciculations, cramps, progressive dysarthria, or progressive swallowing difficulty.
- Referral urgency matters: NICE says slowly progressive limb or neck weakness should be referred for neuromuscular assessment; swallowing impairment makes this urgent; breathlessness at rest or when lying flat makes it immediate.
- Management is multidisciplinary from the point of diagnosis, with attention to respiratory support, nutrition, communication, mobility, advance planning, and carer support.
Recognition in non-specialist settings
- Common GP presentations: foot drop, hand weakness, clumsiness, frequent tripping, slurred speech, choking episodes, or unexplained weight loss with progressive motor symptoms.
- The pattern is progressive and motor-predominant. Sensory symptoms are not the dominant story, so a “weak but not numb” history should raise suspicion.
- Do not anchor on musculoskeletal explanations when weakness, wasting, and fasciculations are progressive over weeks to months.
Practical GP role after suspicion or diagnosis
- Suspected disease: expedite neurology referral, document swallowing and respiratory symptoms, and avoid delay through repeated community physiotherapy-only pathways.
- Known MND: monitor for orthopnoea, morning headache, ineffective cough, weight loss, aspiration risk, mood symptoms, constipation, sialorrhoea, and pressure-area or equipment needs.
- Drug note: disease-modifying treatment decisions such as riluzole are specialist-led, but primary care often supports ongoing prescribing and wider symptom-control coordination.
Frequently asked questions
What symptom makes the referral urgent rather than routine?
Any evidence of swallowing impairment should make the neuromuscular referral urgent. If the patient has breathlessness at rest or when lying flat, the situation becomes immediate.
What early presentations are often missed?
Progressive hand weakness, foot drop, repeated falls, fasciculations, and gradually worsening speech or swallowing problems are all classic but sometimes initially misattributed to more benign causes.
Is this mainly a sensory disorder?
No. MND is classically a motor syndrome, so the absence of prominent numbness or sensory loss does not make the case less concerning.
