Подробное описание
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.
Aim 3: To identify if neurocognitive function changes in transgender adults.
The investigators hypothesize that:
- Aim 1: Transgender females will demonstrate increased basal CBF and larger CBF responses to acute stress, particularly in areas involved in cognition, memory, and learning, whereas transgender males will display lower basal CBF and lower CBF responses to acute stress.
- Aim 2: Transgender patients will demonstrate significant changes in: a) overall brain structure, b) functional connectivity, and c) task activation.
- Aim 3: Neurocognitive function will increase in transgender females and decreases in transgender males, primarily in the domains of memory, attention, executive function, and processing speed.

Male at birth undergoing GAHT with their Clinical Care Team
|
Two MRI visits (baseline and after 4-6 months of continuous GAHT) will involve structural scans of the brain, scans while performing cognitive tasks, and a scan taken while responding to an inhaled CO2 stressor.
This visit will take approximately 1.5 hours.
Другие имена:
Two cognition and health test trials (baseline and after 4-6 months of continuous GAHT) will involve a body composition scan to determine body fat percentage, muscle mass, and bone density.
This will be followed by a set of cognitive tasks using the NIH Toolbox.
Optional graded exercise test will be performed if the participant consents to this optional procedure (baseline and after 4-6months of continuous GAHT).
to determine cardiorespiratory fitness.
This test will be performed on a cycle ergometer, with a metabolic allowing for the measurement of maximal oxygen consumption via indirect calorimetry.
