Types of Motor neuron disease

✨Hello everyone, welcome to our video about Types of Motor neuron disease.

Before jumping onto the different forms of motor neuron disease let's have a small review of what is motor neuron disease? It is a group of different conditions that affect the nerves located in the brain and spine that starts losing their function over time. These are the rare neurodegenerative conditions that affect the motor neurons. Motor neurons are the type of cells that send the electrical impulses to the muscles to function properly. These diseases can appear at any age but the symptoms are more commonly seen at the age of 40-45 years. The disease is more common in men when compared to women.
Some people suffer from the severe symptoms of motor neuron disease which are usually widespread. However, in some conditions, the disease initially affects the single-limb, especially it's motor function which then progresses faster to become a generalized disease. Motor neuron disease usually results in wasting or weakness of the muscles leading to twitching or fasciculation which is visible underneath the skin. Motor neuron disease can affect both upper and lower motor neurons. If the upper motor neurons are affected, it results in muscle stiffness while the involvement of lower motor neurons results in fasciculation. Initially, any of these neurons are involved but as the disease progresses it involved both the neurons. The motor neuron disease is divided into different forms which are classified on the types of neurons involved and the body part where these symptoms begin.
