Absolutely. In fact, the figure that I had quoted in terms of $750 million, those were the direct costs. Nobody talks at all about the indirect costs, and that's one of the largest areas where there's a huge impact in terms of families.
Parkinson's is not just a disease of the elderly. In fact, it starts in some people in their thirties and forties, in the prime of their lives. There have been studies that have actually shown the near millions of dollars of lost income to the person living with Parkinson's, not to mention the fact that the caregiver has to take time off work. It's a natural assumption that the spouse would take care of the person. One of the major issues related to it, and it all ties in together in terms of depression and relationships between people, is the loss of income and the fact that people lose their sense of self, both the patient as well as the caregiver, who has to now stop his or her career also.
Absolutely, the support of caregivers is key. In the Rising Tide report, that was one of the priorities with regard to Alzheimer's disease.
