简要总结
The purpose of this study is to test whether and how a person's brain changes in the first few months after starting gender affirming hormone therapy (GAHT). The investigators want to know if GAHT changes: 1) cerebral blood flow (CBF), 2) brain structure, connectivity, and cognitive task performance, and 3) neurocognitive function (memory, attention, executive function, processing speed). 36 male at birth and 36 female at birth participants will conduct baseline studies prior to GAHT, with a second identical set of study visits 4-6 months after GAHT begins.
详细描述
The purpose of this study is to assess the effects of GAHT on cerebral structure and function. To this end, this study has three aims:
Aim 1: To identify if transgender males and females demonstrate changes in
- A) basal CBF and
- B) CBF responses to acute stress-particularly in areas involved in cognition, memory, and learning.
Aim 2: To identify if transgender adults will demonstrate significant changes in:
- A) overall brain structure,
- B) functional connectivity, and
- C) task activation.
