As sad as it may seem, there is still no conclusive medical test that can predict Parkinson’s disease. Understandably, the disease is too difficult to assess especially in patients with mild symptoms. Still, this should not be a reason to stop living a proactive life. In fact, experts found that symptoms progress slower with people who take a proactive and positive stance in their condition. Maintaining a positive attitude may be difficult to do at all times, but it is essential for one to be actively engaged and happy.
