Parkinson’s is a terrible disease which along with the normal shaking that most people are familiar with often results in dementia. It’s very sad to watch. The disease, which there is very little treatment for, can come on with different symptoms in different people. Some develop a range of motor symptoms like tremors, stiffness and slow movements, while others may experience more non-motor symptoms like anxiety, cognitive changes and even the loss of smell. This has to do with dopamine, which helps the brain control coordination, emotional responses and movement. When you develop Parkinson’s disease, the brain cells that produce dopamine start dying out. If you believe that a loved one is showing symptoms, see a specialist like a neurologist immediately.
