What symptom is associated with Depersonalization?

Feeling disconnected from oneself is a hallmark symptom of depersonalization. Individuals experiencing this phenomenon often report a sense of detachment or estrangement from their own thoughts, feelings, or sense of self. This can manifest as a feeling that they are observing themselves from outside their body or that their thoughts and actions are not their own. This sense of disconnection can be deeply distressing and may occur during episodes of acute anxiety, stress, or trauma.

Other symptoms mentioned in the options, while relevant to various psychological conditions, do not specifically describe depersonalization. The sensation of altered reality can relate to depersonalization but is a broader concept that could also encompass derealization, which refers to a feeling that the external world is unreal. Recurrent flashbacks are typically associated with post-traumatic stress disorder, not depersonalization. Severe mood swings are more characteristic of mood disorders and do not specifically relate to the disconnection and detachment experienced in depersonalization episodes. Thus, the choice best representing depersonalization is the feeling of disconnection from oneself.
