what is the full form of als disease
Amyotrophic lateral sclerosis Amyotrophic lateral sclerosis (ALS), also known as motor neurone disease (MND), and Lou Gehrig's disease, is a specific disease which causes the death of neurons controlling voluntary muscles.[3][5][11] Some also use the term motor neuron disease for a group of conditions of which ALS is the most common.[2] ALS is characterized by stiff muscles, muscle twitching, and gradually worsening weakness due to muscles decreasing in size.[2] This results in difficulty speaking, swallowing, and eventually breathing.[2][3]
Amyotrophic lateral sclerosis ALS itself can be classified a few different ways: by how fast the disease progresses (slow vs fast progressors), by whether it is inherited or sporadic, and by where it starts.[5] Most commonly (~70% of the time) the limbs are affected first. In this case, neurons in the brain (upper motor neurons) and in the spinal cord (lower motor neurons) are dying and this form is called "limb onset". In about 25% of cases, muscles in the face, mouth, and throat are affected first because motor neurons in the part of the brain stem called the medulla oblongata (formerly called the "bulb") start to die first along with lower motor neurons. This form is called "bulbar onset". In about 5% of cases muscles in the trunk of the body are affected first. In all cases the disease spreads and affects other regions.[4] The symptoms may also be limited to one spinal region.
