Which disorder includes symptoms such as intrusive memories or flashbacks?

The correct response is connected to Post-Traumatic Stress Disorder (PTSD), which is characterized by specific symptoms that follow exposure to a traumatic event. Intrusive memories and flashbacks are hallmark symptoms of PTSD that reflect an individual's distressing re-experiencing of the trauma. These symptoms can manifest as involuntary and recurrent thoughts, images, or feelings related to the traumatic incident, leading to distress and impairment in daily functioning.

PTSD can occur after experiencing or witnessing events such as natural disasters, combat, sexual assault, or serious accidents, among others. The presence of these intrusive symptoms makes it distinct from other mood and anxiety disorders, where the focus may be more on persistent sadness, generalized worry, or compulsive behaviors, rather than the re-experiencing of past trauma.

In summary, the linkage of intrusive memories and flashbacks to PTSD highlights the disorder's nature as fundamentally connected to trauma and its psychological aftermath, distinguishing it clearly from the other options listed.
