Which condition is defined by incongruence between assigned gender and experienced gender?

The correct identification of Gender Dysphoria stems from its core definition involving a significant discomfort or distress related to the incongruence between an individual’s assigned gender at birth and their experienced or expressed gender. This condition highlights the mental and emotional challenges a person may face when their gender identity does not align with societal expectations tied to their biological sex.

In the context of the DSM-5, Gender Dysphoria is recognized as a condition that can lead to distress, anxiety, and difficulty functioning due to this misalignment, making it essential for mental health professionals to address and support individuals experiencing these feelings. Treatment often focuses on alleviating that distress and may involve a range of therapeutic approaches, including counseling and, for some, medical interventions.

The other options presented pertain to sleep disorders, which are unrelated to gender identity or gender experience. Sleep Arousal Disorder, Nightmare Disorder, and REM Sleep Behavior Disorder concern varying aspects of sleep disturbances and do not involve gender incongruence as defined in Gender Dysphoria.
