COSTA MESA, Calif., Oct. 13, 2014 /PRNewswire-USNewswire/ -- A one-of-a-kind searchable database of almost 100,000 functional brain scans related to behavior on patients from 111 countries is now poised to change the way psychiatry has been practiced for the last 170 years.
Amen Clinics – a group of 6 nationwide psychiatric clinics founded in 1989 by psychiatrist Daniel G. Amen, M.D. – amassed the database of brain SPECT scans (single photon emission computed tomography), a nuclear medicine study that evaluates blood flow and activity levels. With a generous grant from the Seeds Foundation in Hong Kong, Dr. Amen and his research team led by neuroscientist Kristen Willeumier, PhD, have turned the de-identified scans and clinical information into a searchable database that is shared with other researchers around the world.
In 2014 alone, the database has yielded 16 new [i]studies, including collaboration with researchers at UCLA, Thomas Jefferson University, the University of British Columbia and Nova Southeastern University, demonstrating how functional neuroimaging can add valuable information to better guide patient care and treatments for increased positive outcomes.
Two of the studies were presented at the most recent Society of Nuclear Medicine Meeting in St. Louis.
One showed how the significant brain damage suffered by NFL players differed by position. Lineman had more frontal lobe problems, often associated with judgment and impulse control issues, while defensive backs had more evidence of temporal lobe dysfunction, often associated with memory and temper issues.
The second study showed differences in depressed patients of those who responded to treatment versus those who didn't, potentially helping psychiatrists make better decisions for their patients.
In addition, the prestigious Archives of Clinical Neuropsychology recently published 10 studies with findings from the Amen Clinics SPECT imaging database. A few of the highlights of those studies include:
- Patients with eating disorders had more activity in an area of the right frontal lobe during a concentration task, showing they may have a tendency to focus too much on things that are wrong or upset them and giving clinicians potential guidance on an area to target for treatment.
- Patients with aggression showed lower blood flow in multiple areas of the brain, especially in the amygdala – which performs a primary role in the processing of decision-making, memory and emotional reactions – further supporting previously published studies and potentially guiding treatment interventions targeted to those areas.
- Patients with ADD/ADHD have blood flow issues in several areas of the brain, especially the prefrontal cortex (judgment, focus and forethought) and cerebellum (coordination). The study helps understand why strategies to stimulate the brain are often helpful.
The magnitude and clinical significance of the Amen Clinics database – being the world's largest SPECT imaging database having such volume and breadth of data from patients 9 months old to 101 years of age – makes it a treasure trove for researchers to help advance and revolutionize the practice of psychiatry.
"It is my hope," said Dr. Amen, "that our database will begin to change psychiatric practice from the current approach of just making diagnoses based on symptom clusters – which is the same today as in Abe Lincoln's time – to using neuroimaging tools such as SPECT on a day-to-day basis to better target treatment and improve outcomes for people who suffer."
