JRCT ID: jRCTs031230715

Registered date:18/03/2024

Basic Information

• Date of first enrollment: 18/03/2024
• Target sample size: 20
• Study type: Interventional
• Intervention(s): Administration unapproved drug

Outcome(s)

• Primary Outcome: Has a history of adversity/suicidal behavior, Has a history of adversity/no history of suicidal behavior, Healthy person, Differences in AMPA receptor density in the brain between the three groups

Secondary Outcome

1) Has a history of adversity/suicidal behavior, Has a history of adversity/no history of suicidal behavior, Correlation between AMPA receptor density in the brain and psychological test results (HAM-D (depression), ACEs (adversity experiences), C-SSRS (suicidal tendency) for the above two groups.
2) Has a history of adversity/suicidal behavior, Has a history of adversity/no history of suicidal behavior, Correlation between brain AMPA receptor density and epigenomic results for the above two groups.
