Nurse Helping Elderly Doctors are not exactly sure what causes Parkinson’s Disease, but numerous medical studies have found that this condition results from problems with the brain’s neurological structure. Certain nerve cells in Parkinson’s patients malfunction and effectively die for no apparent reason in the region of the brain known as the substantia nigra. According to the National Institutes of Health, the nerve cells located in this portion of the brain are responsible for releasing neurotransmitters such as dopamine that assist the body in controlling such functions as movement and coordination. Although we are not sure what the cause(s) of Parkinson’s Disease may be and there is no cure for the disease today, there are a number of warning signs that accompany its onset. Detecting and diagnosing the disease earlier can help improve patient outcomes.
