Parkinson disease is a progressive disorder of the nervous system. The disorder affects several regions of the brain, especially an area called the substantia nigra that controls balance and movement. Often the first symptom of Parkinson disease is trembling or shaking (tremor) of a limb, especially when the body is at rest. Typically, the tremor begins on one side of the body, usually in one hand. Tremors can also affect the arms, legs, feet, and face.

During your menstrual cycle, the lining of your uterus thickens to get ready for pregnancy. Then, during your period, your body sheds the uterus lining along with blood. The amount of blood and fluid lost is usually between 4 and 12 teaspoons each cycle.The average menstrual cycle lasts 28 days (counting from the first day of bleeding to the first day of the next cycle).For some women, though, cycles can be as short as 21 days. For others, they can be as long as 35 days.
