Amyotrophic lateral sclerosis (ALS). This is the 'classical' MND and the most common type. About 8 in 10 people with MND have this type. Symptoms tend to start in the hands and feet. The muscles tend to become stiff as well as weak at first. Progressive bulbar palsy (PBP). About 2 in 10 people with MND have this type. The muscles first affected are those used for talking, chewing and swallowing (the bulbar muscles). Progressive muscular atrophy (PMA). This is an uncommon form of MND. The small muscles of the hands and feet are usually first affected, but the muscles are not stiff. Primary lateral sclerosis (PLS). This is a rare type of MND. It mainly causes weakness in the leg muscles. Some people with this type may also develop clumsiness in the hands or develop speech problems.
