The motor neurone diseases (MND) are a group of              neurological disorders that selectively affect motor neurons.

MND includes the following clinical types: Both upper and lower motor neuron damage result in amyotrophic lateral sclerosis (ALS). The diseases resulting from lower motor neuron damage include progressive spinal muscular atrophy (PSMA) and progressive bulbar palsy (PBP). ALS is the most typical and common type. All over the world, ALS is considered to be synonymous with MND. It is also called Lou Gehrig's disease in the USA.

Amyotrophic lateral sclerosis is characterized by the gradual degeneration and death of motor neurons. ALS is an invariably fatal neurological disease that attacks the nerve cells (neurons) responsible for controlling voluntary muscles (such as those in the arms, legs, and face).
