UT researchers study intersection of trauma, genetics in bipolar disorder development

Researchers at the University of Texas and the University of Cincinnati are conducting a five-year study to understand the development of bipolar disorder in young adults.

The researchers are nearing the end of the first year of the study, which involves participants ages 14 to 21 who have a biological parent with bipolar disorder.

Bipolar disorder is “about 85% purely genetic in origin,” said Dr. Stephen Strakowski, a professor of psychiatry and behavioral sciences and one of the study’s principal investigators.

The researchers are still recruiting participants, and they plan to track the same people throughout the study.

Dr. Jorge Almeida, the director of the Bipolar Disorder Center at Mulva Clinic for the Neurosciences and the study’s other principal investigator, said the research includes regular mood assessments, yearly neuroimaging, cognition studies and functional magnetic resonance imaging to investigate how the prefrontal cortex in the brain develops in people at risk of developing bipolar disorder.

Strakowski said the unique aspect of the study is that it looks at how both childhood trauma and genetic risk might affect the development of bipolar disorder. Similar studies don’t focus on childhood trauma at the level this study does, Strakowski said.

“People who experience childhood trauma also experience changes in brain development. We’re evaluating histories of trauma and seeing how it intersects with genetic risk,” Strakowski said.

Avery Bowman, a neuroscience and health and society junior at UT with bipolar disorder, said she received her diagnosis when she was 19. Bowman said receiving an early diagnosis was crucial in helping her regulate her symptoms.

“I experience psychosis, and psychosis gets worse over time, so because I was able to get diagnosed early, I was able to get on the right treatment plan to stop that in its tracks,” Bowman said.

People with bipolar disorder experience states of mania and depression. The researchers said they are hopeful that their study can encourage earlier intervention for people with bipolar disorder who struggle with these symptoms.

“It’s a disease that starts in young adults,” Almeida said. “If (people with bipolar disorder) are not properly treated from the beginning, that can significantly impact and deteriorate the rest of their lives.”

Strakowski said cost barriers may restrict some people’s access to mental health care, and the Bipolar Disorder Center is breaking down those barriers.

“Our bipolar programs are working with a large insurance company to figure out a way to intervene earlier and help families before they end up in the hospital,” Strakowski said.

Almeida said the life span for people with the disorder is 10 years less than the average life span. There is also a high rate of suicide for people with the disorder, Almeida said. For these reasons, Almeida said bipolar is an important disorder to study.

“If you intercept these recurring illnesses earlier, the outcomes are always better,” Strakowski said. “If we can intervene, we can stop it from negatively impacting people’s lives.”
