More than 21 million people worldwide suffer from schizophrenia, a profound mental illness that interrupts thinking, language and perception. Quite a few schizophrenic people experience delusions and hear voices. Many of the disease’s symptoms stem from faulty communication between brain cells. And, for decades, scientists have searched for a cure in the brain.
Now researchers say they’ve discovered that the way to heal schizophrenia might be through the gut. There’s an ecosystem of bacteria and microbes that live in our digestive tracts, known as the gut microbiome. And these may lead to some features of schizophrenia, an international team of scientists announced this week in the journal Science Advances. The discovery could revolutionize treatment options for schizophrenia.
