Certain types of nerve damage, if caught early enough, are currently curable by successfully treating the underlying cause of the condition, explains WebMD. However, there are over 100 types of nerve damage that are caused by anything from cancer treatment to diabetes.
An example of nerve damage that is reversible is nerve damage caused by nutritional deficiencies, which is treated by controlling the deficiency, according to WebMD. Surgery or physical therapy is used to address nerve damage caused by compression or trauma to the nerves. In some cases, nerve damage that is caused by certain medications is successfully treated by changing medications.
