PD Guide
Medical History
Image from NIA, NIHMedical history may also affect risk for PD. A physically active lifestyle is associated with reduced risk for PD (Chen et al., 2005). A lower incidence of cancer has been proposed to correlate with a higher risk of PD, though further confirmation of this association is needed (Olsen et al., 2005; Inselberg et al., 2007; Driver et al., 2007). As cancer can have both environmental and genetic causes, this potential correlation provides and interesting link between the two diseases. Head trauma has been also linked with development of PD (Goldman et al., 2006).
