Parkinson Disease
Parkinson’s disease is a nervous system disease that affects your ability to control movement. The disease usually starts out slowly and worsens over time.
Causes:
Genes : Researchers have identified specific genetic mutations that can cause Parkinson's disease. But these are uncommon except in rare cases with many family members affected by Parkinson's disease.
Environmental triggers : Exposure to certain toxins or environmental factors may increase the risk of later Parkinson's disease, but the risk is relatively small.
Symptoms:
Tremor: A tremor, or shaking, usually begins in a limb, often your hand or fingers. You may rub your thumb and forefinger back and forth, known as a pill-rolling tremor. Your hand may tremble when it's at rest.
Rigid muscles :Muscle stiffness may occur in any part of your body. The stiff muscles can be painful and limit your range of motion.
Impaired posture and balance : Your posture may become stooped, or you may have balance problems as a result of Parkinson's disease.
Speech changes : You may speak softly, quickly, slur or hesitate before talking. Your speech may be more of a monotone rather than have the usual inflections.
