Machine Learning Study Finds Standardized Brain Scan Biomarkers Detect Depression with 66% Accuracy

Machine Learning Study Finds Standardized Brain Scan Biomarkers Detect Depression with 66% Accuracy

Posted on: March 16th, 2021 by NeuroHealth Associates

Neurofeedback Therapy is based on cognitive mapping and neurocognitive evaluations of a patient’s brain. The brain is the most complex organ in the human body, so using technology to help doctors and clinicians understand it has helped the field move into the future at an astounding rate. Machine learning is being used to try and map the human brain and how it functions.

Research into Biological Signs of Depression

Scientists have been studying biological signs of depression in the brain, looking for markers that could be used to identify the disorder. A team of scientists recently developed a technique using machine learning that can identify whether a given patient’s brain scan shows one of depression’s neural signatures…

Clinicians currently diagnose major depressive disorder, commonly called depression, based on a patient’s reported symptoms, like changes in mood, activity enjoyment, appetite, or sleeping, for example. But people with depression can show a wide range of different symptoms, which means that depression looks different in each person … Grouping people with wide-ranging symptoms under one category also masks the fact that different processes in the brain might underlie depression in different individuals. For these reasons, neuroscientists have been looking for neural signatures or biomarkers of depression…

Using the brain network biomarker, their algorithm could correctly identify which participants had depression 66% of the time.

While 66% accuracy may not sound high, it is an improvement on current accuracy levels of diagnosis by human clinicians, particularly general physicians who aren’t trained in psychiatry.

What Clients Say About Us


Julie W.
Teachers made huge comments on his math skills and behavior. I also saw this at home with understanding of what I said to him registering more with him. I saw this in his eyes: recognition. Fewer outbursts of anger.

Anita M.
I am extremely happy with my son’s outcomes and feel very fortunate to have encountered Dr. Bonesteel early in my child’s life. This method has dramatically changed his ability to focus and take initiative. I feel confident that my son’s life has been dramatically enhanced. I can’t express my appreciation fully in words.

Mary B.
Dr. Bonesteel has masterfully, compassionately, and extremely kindly helped me navigate through a history of childhood and marital abuse, a child with twenty years of struggle with life-threatening physical and emotional illness, extended family discord, and disharmony with my child with severe depression. I am blessed to have found Neurohealth Associates.
