also referred to as complex trauma and developmental trauma: As opposed to PTSD, which describes the effects individuals may be left with after a one-time big T traumatic event, complex trauma is repeated trauma, which is often (but may not be) more subtle. The long-term exposure to pervasive trauma, abuse and/or neglect affects an individual into adulthood, leaving them with a dysregulated nervous system, intense feelings of shame, compromised safety in this world, and the inability to trust others. While CPTSD is usually developmental trauma (it occurs in early life and literally shapes an individual in a manner that leaves them feeling anxious and isolated), it can also occur later in life when experience prolonged trauma or abuse.
