G30-G32: Other degenerative diseases of the nervous system

G31: Other degenerative diseases of nervous system, not elsewhere classified

The group of conditions classified under "Other degenerative diseases of the nervous system, not elsewhere classified" refers to a set of diseases characterized by progressive deterioration of the nervous system. These diseases generally involve the gradual loss of nerve function, which can affect both the central and peripheral nervous system. Common symptoms across this group can include incoordination, muscle weakness, cognitive decline and abnormal movements. Often, these conditions begin subtly and progress slowly over time, making early detection challenging. The causes behind these diseases can be various, ranging from genetic mutations to environmental factors such as exposure to certain toxins. As these conditions progress, they often affect a person’s ability to move, think, and even perform basic tasks. However, the specific symptoms and disease progression can vary widely among the different conditions in this group.
