What are the first symptoms of motor neurone disease?

Motor neurone disease (MND) symptoms usually begin gradually. The most common first sign is muscle weakness in a limb – a stumble, dropping objects, or weakening grip.

Clumsiness, tripping and dropping things more often are typical early complaints, sometimes with a leg dragging or foot drop from weaker ankle muscles. Studies show that a quarter of cases begin differently, with slurred speech or swallowing problems instead.

In roughly one in four cases, the first symptoms affect speech and swallowing muscles, with increasingly slurred speech often the earliest sign. Other early features include muscle twitching, cramps, fatigue and unexplained weight loss.

Progression varies between patients – some people decline rapidly, while others deteriorate much more slowly. Weakness spreads to other limbs, then to speech, swallowing and breathing muscles. Most patients need a wheelchair within months of diagnosis.

There’s no cure, and MND is ultimately fatal, though survival time ranges from under a year to many years, with average life expectancy after diagnosis typically two to five years.
