Arthur Silverstein is experiencing flashbacks and nightmares stemming from his traumatic past. What is the likely diagnosis?

The symptoms of flashbacks and nightmares that Arthur Silverstein is experiencing are characteristic of Post-Traumatic Stress Disorder (PTSD). PTSD commonly arises after an individual has been exposed to a traumatic event, and it is marked by persistent re-experiencing of that trauma through intrusive memories, flashbacks, or distressing dreams related to the event.

Flashbacks serve as a way for the individual to relive the traumatic experience, which can be overwhelming and cause significant distress. Nightmares can add to the emotional toll, disrupting sleep and contributing to a cycle of anxiety and fear surrounding the trauma.

In contrast, the other conditions mentioned do not predominantly include these specific symptoms. Generalized Anxiety Disorder primarily involves excessive worry and anxiety about various aspects of life without the reliving aspect seen in PTSD. Major Depressive Disorder focuses more on pervasive sadness, lack of interest, and other depressive symptoms, while Bipolar Disorder is characterized by episodes of depression and mania or hypomania rather than trauma-related symptoms. Hence, Arthur's experiences strongly align with PTSD, confirming it as the most appropriate diagnosis.
