Combating depression is UCLA’s second Grand Challenge

Genetic study of 100,000 people will be the largest ever on a single disorder

Depression is the leading cause of disability worldwide, but research spending on the disorder substantially lags that of other illnesses.

In an effort to place depression front and center on the national and international research agendas, UCLA has launched the Depression Grand Challenge, which aims to reduce the health and economic impacts of depression by half by the year 2050.

Depression costs the U.S. economy more than $200 billion annually in medical costs and lost productivity. It also is the largest contributor to the risk for suicide, and more than 40,000 Americans take their own lives each year.

And although depression is the leading cause of disability worldwide, research spending on the disorder substantially lags that of other illnesses.

The UCLA effort is in line with President Barack Obama’s 2013 call for companies, research universities and other organizations to solve grand challenges — which he referred to as “ambitious but achievable goals.” UCLA’s Depression Grand Challenge is the largest university-led grand challenge, with an anticipated budget of $525 million for the first 10 years of its planned 35-year duration.

The program is UCLA’s second Grand Challenge, following the ongoing Sustainable L.A., a research initiative launched in 2013 to develop a blueprint to transition Los Angeles County to 100 percent renewable energy, 100 percent locally sourced water and enhanced ecosystem health by 2050.

“The two Grand Challenges are the biggest, most collaborative and potentially most transformative efforts UCLA has ever undertaken,” said UCLA Chancellor Gene Block. “They represent a new way of conducting research to solve the biggest problems of our society, and they are challenges we’re uniquely qualified to take on.”

The new grand challenge focused on depression comprises four components:

  • A 100,000-person study to discover the causes of depression — the largest-ever genetic study for a single disorder.
  • An effort called Discovery Neuroscience that is aimed at understanding how depression arises. Researchers will use findings from the genetic study and examine the molecular mechanisms and brain circuitry through which genetic and environmental factors lead to depression.
  • An innovative treatment center that will provide state-of-the-art treatment for tens of thousands of study participants. As Discovery Neuroscience reveals better ways to treat depression, the treatment center will deliver new, effective therapies and preventive measures.
  • A focus on understanding and eliminating the stigma associated with depression. Research has shown that the shame or frustration felt by those with depression often is a barrier to seeking diagnosis and to beginning and continuing treatment. To overcome this hurdle, the grand challenge will begin a research, outreach and education program targeting both the local and global communities.

Conceived in 2012 through the brainstorming efforts of more than 30 UCLA faculty members, the Depression Grand Challenge team now comprises more than 100 researchers from more than 25 academic departments.

The grand challenge is being led by Dr. Nelson Freimer, UCLA’s Maggie G. Gilbert Professor of Psychiatry and Biobehavioral Science and director of the Center for Neurobehavioral Genetics in the Jane and Terry Semel Institute for Neuroscience and Human Behavior at UCLA.

“Advances in technology for genetic research have now made it possible for us to discover the causes of depression,” Freimer said. “We know a genetics-based strategy will be successful, just as it has been with heart disease, diabetes and cancer. But finding the causes of depression is just the first step.

“We have to understand not just why, but how, depression arises, and we have to be in a position to take that knowledge directly back to our patients. Depression is such a complex disease that we are going to have to understand it from all angles — its basis in the brain, its environmental roots and its social impact. This is why a university-wide effort is essential.”

To lead the massive genetics study, UCLA has recruited a world-renowned authority on the genetics of depression. Jonathan Flint, formerly of Oxford University, led the first study that obtained clear evidence of the specific genes contributing to the disorder.

The two other members of the challenge’s leadership group are Michelle Craske, a professor of psychology, psychiatry and biobehavioral sciences and the director of the Anxiety and Depression Research Center at UCLA, who will lead the development of the innovative treatment center; and S. Lawrence Zipursky, a UCLA professor of biological chemistry and Howard Hughes Medical Institute investigator, who will lead the development of Discovery Neuroscience. Zipursky recently received the Louisa Gross Horwitz Prize for his work on a molecular identification system that helps neurons to navigate and wire the brain.
