Study Identifies Specific Brain Regions Showing Boosted Activity in Individuals with Depression
In a groundbreaking neuroimaging study, researchers have found that individuals with depression display notably elevated blood flow across several brain regions. The study’s key findings reveal increased blood flow in essential areas such as the frontal cortex, anterior cingulate cortex, basal ganglia, thalamus, and cerebellum among those with depression.
These heightened levels of regional cerebral blood flow (rCBF) are associated with more intense depression symptoms, underscoring the complex connection between brain activity and mental health.
Published in Translational Psychiatry, this large-scale study is among the most comprehensive to date, examining 338 patients with major depressive disorder (MDD) alongside 103 healthy participants. Neuroscientists from Children’s Hospital Los Angeles, USC, and NYU led the research, drawing on data from eight Amen Clinics locations nationwide.
With 11 outpatient psychiatric centers across the nation, Amen Clinics has led the way in utilizing single photon emission computed tomography (SPECT) imaging for over three decades.
Dr. Daniel G. Amen, founder of Amen Clinics, underscored the importance of the study’s findings, stating, “This study highlights the crucial role of brain imaging in understanding mental health. It’s clear that to achieve good mental health, we must first focus on maintaining a healthy brain.”
The study revealed that women and older adults with depression exhibited especially elevated blood flow in certain brain regions, indicating that blood flow patterns in depression may differ according to age and gender.

Brain SPECT Imaging Brings Fresh Hope for Depression Treatment
This innovative study underscores the powerful potential of brain SPECT imaging for diagnosing and treating major depression. This innovative imaging method could revolutionize clinical practice, equipping doctors with valuable new tools to support patient care.
Basic Results
Correlation to Severity: The study found that higher levels of depression severity were associated with increased blood flow in the basal ganglia, hippocampus, and cerebellum. This indicates that SPECT scans can be used not only to diagnose depression but also to evaluate its severity, allowing doctors to tailor treatments more precisely.
Age and Gender Perspectives: The study revealed that older adults and women exhibited more significant changes in brain blood flow, suggesting that SPECT imaging can provide important insights into how depression uniquely impacts different demographic groups. This could pave the way for more tailored and effective treatment plans.
Target for New Treatments: Increased blood flow in patients with depression likely reflects pathogenic hypermetabolism. This insight opens up possibilities for developing innovative therapies aimed at addressing this hypermetabolic activity, providing renewed hope for patients unresponsive to existing treatments.
The Clinical Implications
Brain SPECT imaging serves as a valuable tool for advancing researchers’ understanding of depression. By offering detailed visualizations of brain activity, it enables doctors to make more precise diagnoses, gauge the condition’s severity, and create tailored treatment plans. This imaging technique’s capacity to detect shifts in brain function also paves the way for innovative treatments that address the metabolic changes linked to depression.
Upcoming Directions:
This study represents a major advancement in understanding and treating depression. Upcoming research will likely aim to enhance these imaging methods further and to design targeted treatments informed by these insights. SPECT imaging holds immense potential to transform mental health care, providing renewed hope to millions of patients globally.
