Both functional and organic disorders of the central nervous system (CNS) can cause serious physical harm and emotional distress to patients. Previous research suggests that parent-related factors may be associated with CNS disorders in the population, and in this project we have focused on the genetic factors of both parents, the physical condition of the pregnant woman before and after pregnancy, and the level of health care she receives. Using the ALSPAC data, we hope to further identify specific factors and quantify the strength of their influence.
