How common is motor neurone disease?
There are three main types of MND: • amyotrophic lateral sclerosis (ALS) – is the most common form of MND and accounts for 60-70% of cases, • progressive bulbar palsy (PBP) – accounts for 20% of MND cases, and • progressive muscular atrophy (PMA) – accounts for 10% of cases. The symptoms of all three forms of MND are similar, although there is a difference in how quickly each type progresses. There is also a very rare form of MND known as primary lateral sclerosis.
