Q

Origin of bipolar disorders

A
  • A family history of bipolar disorder is a significant risk factor for bipolar disorders.
  • The concordance rate for bipolar disorders in identical twins are higher than in fraternal twins.
  • Higher concordance rates in identical twins suggest a stronger genetic influence on the trait or disorder being studied.
  • In the 1980s, the Amish community was involved in a genetic research study.
  • Amish keep genealogical records, and few outsiders marry into their community.
  • Families where bipolar disorder occurred among members, all seemed to have similar genetic traits or differences compared to other families.
  • These genetic similarities were linked to the presence of bipolar disorder within those specific families.
  • Bipolar disorders are inherited through a combination of genes, not just one.
  • Scientists are looking at many genes that might be involved.
  • In families with bipolar disorders, each new generation tends to have more severe symptoms starting at younger ages.
