This refers to a group of progressive disorders where there is destruction of motor neurones (the nerves that control voluntary muscle activity such as speaking, walking, breathing, and swallowing.)  Symptoms include: gradual weakening, shrinking of muscles and uncontrollable twitching of the muscles.  Sensation, memory and personality are not usually affected.

 

The diagnosis is made by history, examination findings, nerve conduction studies and electomyography tests.  There are often other tests looking for other diseases to exclude before the diagnosis is confirmed.

There is no cure for MND. Physiotherapy and occupational therapy can improve posture, prevent joint pain and maximise independence. There are some medicines used to treat particular symptoms. There is a specialist clinic for patients with MND at the Greenlane Clinical Centre.

 

The course of disease varies depending on the type of MND and the age of onset but it is progressive.
