Although, for those neurobiologically set up with OCD, many have not experienced symptoms that have interfered with their daily lives until experiencing a stressful life event. Examples of stressful events often seen to trigger symptoms include major illness, childbirth and parenting a newborn (often called "Postpartum OCD"), a trauma or an accident, etc..
With a major stressor, OCD can truly explode creating the perspective that it "came out of nowhere". However, generally speaking, the OCD was merely lying dormant, waiting for the right trigger. It can be truly jarring and disrupt life with intense suffering.
Hence, public awareness of OCD is vital, so that those suffering in silence and lack of knowledge about this syndrome can get the help they need.
