From the Guidelines

Being transgender is fundamentally different from a delusional belief, as it is a genuine experience of gender that differs from one's sex assigned at birth, recognized by major medical and psychological organizations as a normal variation of human experience. This understanding is supported by recent guidelines and research, including the revised Endocrine Society 2017 treatment guidelines, which emphasize the importance of knowledgeable and trained providers, safe and effective hormone regimens, and fertility preservation counseling for transgender and gender-diverse (TGD) patients 1.

Key Differences

  • Transgender identity is not a fixed false belief, but rather a deeply felt internal sense of self that is aware of the physical body but experiences a persistent incongruence between gender identity and physical characteristics.
  • Unlike delusions, transgender identities have biological underpinnings, including genetic and neurological factors, as suggested by research in the field of TGD medicine 1.
  • Treatment approaches for transgender individuals, such as gender-affirming care, including social transition, hormone therapy, or surgeries, consistently improve psychological well-being and quality of life, which would not occur if their identity were delusional in nature.

Medical Recognition

The World Health Organization's International Classification of Diseases (ICD) has moved away from using the term "gender dysphoria" for the diagnosis of transgender individuals, replacing it with "gender incongruence" in a new chapter on sexual health, reflecting a shift towards recognizing transgender identities as a normal variation of human experience rather than a mental health condition per se 1.

Implications for Care

Given the significant differences between being transgender and holding a delusional belief, healthcare providers should approach transgender individuals with a comprehensive understanding of their unique needs and experiences, providing care that respects and affirms their gender identity, rather than attempting to correct a perceived false belief. This approach is crucial for improving the health outcomes, morbidity, mortality, and quality of life for transgender individuals, as highlighted by the need to address the unique healthcare disparities they face, including lack of access to healthcare, discrimination, and gaps in medical and mental health research 1.

From the Research

Definition of Transgender

  • Transgender individuals are those whose gender identity differs from that recorded at birth, usually based on visualization of external sexual anatomy 2.
  • Gender identity is a person's internal sense of being male, female, or something else, which may or may not align with their assigned sex at birth.

Difference from Delusional Belief

  • Transgender identity is not considered a delusional belief, but rather a legitimate aspect of human diversity 3, 4.
  • Research suggests that transgender individuals have a unique brain phenotype that differs from cisgender individuals, which may contribute to their gender identity 5.
  • Gender-affirming hormone therapy has been shown to be effective in aligning physical characteristics with gender identity and improving mental health symptoms 3, 4, 6.

Key Characteristics

  • Transgender individuals may experience gender dysphoria, which is a feeling of discomfort or distress due to the mismatch between their gender identity and assigned sex at birth 3.
  • Gender-affirming care, including hormone therapy and surgery, can help alleviate gender dysphoria and improve overall well-being 2, 3, 4, 6.
  • Transgender individuals require respectful and individualized care, including the use of preferred names and pronouns, to ensure a positive and supportive healthcare experience 4.
