“My speech has got slurred and I keep dropping things and tripping — but I’ve no pain at all”

PROGRESSIVE, PAINLESS, PURELY MOTOR weakness with a MIX of upper and lower motor neurone features — muscle WASTING, FASCICULATIONS and weakness alongside brisk reflexes/spasticity/upgoing plantars — plus BULBAR symptoms (dysarthria, dysphagia) and NOTABLY no sensory loss and (early) no eye-movement or sphincter involvement, is the highly concerning red-flag pattern of MOTOR NEURONE DISEASE (MND/ALS). The painless, motor-only, progressive nature with fasciculations is the key flag. Look deliberately for combined UMN and LMN signs across regions and intact sensation (recorded findings, video inspection, or an in-person examination if not yet done), which strongly suggests MND, and briefly consider mimics (cervical myelopathy/radiculopathy — usually with sensory signs; multifocal motor neuropathy; myasthenia — fatigable, no wasting/fasciculations; stroke — sudden; benign fasciculations — no weakness/wasting). Refer URGENTLY to NEUROLOGY without delay, specifying the possible diagnosis of MND in the referral letter (NICE NG42): MND is a clinical diagnosis confirmed by a neurologist (with EMG/nerve conduction and investigations to exclude mimics), and early referral matters for timely diagnosis, disease-modifying treatment (riluzole), and access to the multidisciplinary team (respiratory/NIV, nutrition/SALT/PEG, physiotherapy, OT, communication aids, palliative care and advance care planning) — so do not watch-and-wait a progressive motor syndrome. The communication core is handling a frightening, potentially life-limiting possibility honestly but compassionately WITHOUT giving him a firm diagnosis you cannot confirm in primary care (NG42: the consultant neurologist gives the diagnosis): be honest that the symptoms are significant and need urgent specialist assessment, avoid both false reassurance and a definitive label, explore concerns, and answer honestly if the patient asks directly (acknowledging what is being looked for) while supporting him, and asking about driving (stop if symptoms make it unsafe; the DVLA must be told once MND is diagnosed).
