Scientists discover 5 hidden brain patterns behind depression
Researchers at the University of Helsinki have identified five distinct brain activity patterns associated with major depressive disorder. This discovery suggests that depression is biologically heterogeneous, which could lead to more personalized treatment approaches.
Why it matters
Moving toward precision psychiatry could significantly improve the efficacy of treatments for millions of people suffering from depression.
Two people diagnosed with depression can experience vastly different symptoms. One might struggle with persistent anxiety and repetitive negative thoughts, while another may experience trauma related symptoms or substance abuse. But do these differences also appear in the way their brains function?
Researchers at the University of Helsinki investigated this question and uncovered a striking finding: people with the same depression diagnosis can have dramatically different patterns of brain activity. In some cases, communication between brain regions was unusually strong, while in others, it was weaker than normal.
Depression is a major global health concern. According to the World Health Organization (WHO, 2025), approximately 332 million (5.2%) adults worldwide are affected. In Finland, depression is the leading individual cause of both extended sick leave and disability pensions.
