The condition known as ___________ is caused by a psychological traumatic event outside of usual human experience.

Post-traumatic stress disorder (PTSD) is characterized by the development of certain symptoms following exposure to a traumatic event that is outside the realm of typical human experience, such as military combat, natural disasters, or violent assaults. Individuals with PTSD may experience flashbacks, severe anxiety, and uncontrollable thoughts about the event. These reactions are a way the body attempts to cope with overwhelming stress and trauma.

In contrast, psychosis refers to a disconnection from reality, which may involve hallucinations or delusions but is not necessarily tied to a specific traumatic event. Bipolar disorder involves mood swings between depression and mania, while borderline personality disorder is characterized by instability in moods, behavior, self-image, and functioning. These disorders do not specifically develop as a direct result of a traumatic experience in the same manner as PTSD. Hence, PTSD clearly stands out as the condition linked directly to experiencing a psychological trauma outside of usual human experience.
