Authorizes the Secretary of HHS to expand and intensify activities pertaining to postpartum depression or postpartum psychosis, including research to expand the understanding of the causes of, and treatments for, postpartum conditions. Expresses the sense of the Congress requesting the NIH to conduct a nationally representative longitudinal study over the FY 2010-2019 period of relative mental health consequences for women of resolving a pregnancy. Requires a report to the Congress on these efforts by March 23, 2015 and periodically thereafter (and other reports as called for in the section). Stipulates that the Secretary may make grants available to eligible entities for projects for the establishment, operation, and coordination of effective and cost-efficient systems for the delivery of essential services to individuals with or at risk for postpartum conditions and their families. Authorizes to be appropriated (but does not delineate a separate Congressional appropriation) $3 million for FY 2010 and such sums as may be necessary for FYs 2011-2012.
