Gradual freezing disease is medically called motor neuron disease. The main reason is that a large number of motor nerves die, resulting in a series of sensory and perceptual obstacles. In the later stage, patients will gradually lose a series of functions such as swallowing and breathing, and eventually die. Its etiology is related to heredity, poisoning and other reasons, but it is only a guess and there is no basis. So at present, all treatments are symptomatic, and the current medical level can't overcome this disease.

In recent years, with the development of media network, the word "gradual freezing" has become more and more familiar to the public. Although the incidence rate is very low, because the patients are awake during the whole onset process, they are feeling the passing of life bit by bit, so the mental pressure is huge and their emotions are often out of control.
