Motor neurone disease

Also called MND, Amyotrophic lateral sclerosis, or ALS

Motor neurone disease (MND) is a rare condition that affects the brain and nerves. It causes weakness that gets worse over time, affecting movement, speech, swallowing and eventually breathing. It usually affects people in their 60s and 70s. A small number of cases run in families.

What it is

There is no cure, but medicine such as riluzole may slow it slightly.

A specialist team helps with mobility, speech, nutrition, breathing support and planning ahead.

Common signs

  • Weakness in the ankle or leg, tripping
  • Slurred speech
  • Weak grip
  • Muscle cramps and twitches
  • Weight loss
  • Difficulty swallowing

How it is usually diagnosed

  • Examination by a neurologist
  • Nerve conduction studies and EMG
  • MRI scans and blood tests to rule out other conditions

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Neurology letters
  • EMG reports
  • Breathing test results
  • Care plans and advance decisions

Questions to ask your doctor

  • What support will we have from the specialist team?
  • When should we think about breathing or feeding support?
  • Should my family have genetic testing?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Choking or sudden difficulty breathing: call 112
