Degenerative nerve disease is a term that describes diseases that affect the body’s activities: balance, movement, heart function, talking and breathing. These activities become harder to perform as the disease intensifies with age. Types of degenerative nerve diseases include Parkinson’s disease, Huntington’s disease, and Lewy body disease. General symptoms for most degenerative nerve diseases include tingling, numbness, limb pain and weakness. Most degenerative nerve diseases occur in middle or old age. A physician can diagnose degenerative nerve disease using specialized nerve tests and a procedure that assesses muscle and nerve function. Most degenerative nerve diseases cannot be cured, so treatment is targeted around managing symptoms. Treatment differs depending on the specific disorder, but commonly medication, physical therapy and sometimes surgery are used to manage symptoms.
