Studies show that loss of the sense of smell could be an early indicator of the onset of PD. In some cases, the loss of smell occurs before the loss of motor function. However, not all PD patients will lose their sense of smell. If you find that you cannot smell things you normally would, it could be an indicator that the brain cells controlling this sense are damaged. Sense of smell can however also occur as a side effect of certain drugs or health problems such as a cold.

1. Constipation

Constipation may be caused by a number of factors including lack of fiber in the diet, dehydration or using certain drugs. It can however be a sign of PD. Parkinson’s disease can result in the damage of autonomic nervous system. This is a network of nerves that are responsible for the coordination of the smooth muscles in the bowels. If this damage occurs, bowel movements become slow leading to constipation.
